How to Find the Top App Development Companies in Vietnam?

Vietnam is quickly moving up the ranks to become one of the most popular places for app development for a number of reasons. Even so, it is still a fairly new place for many businesses to outsource their work. Because it’s still a fresh market, many businesses are grappling with finding the top app development companies in Vietnam. This article will help alleviate such issues.

In the first section, let us delve into the reason why Vietnam is the market it is today. 

3 Reasons Why Vietnam Is One Of The Top App Development Markets Today

Do you know why so many businesses are starting to hire web and app development companies in such large numbers? It is much easier to have someone else design your website than to hire a full-time team of developers. This not only gets rid of the hiring costs, but it also cuts down on the costs of building structures. Vietnam is a great place for businesses that want to make technological advances because it is a new destination for app development outsourcing.

There are 3 main reasons as to why outsourcing app development to Vietnam is such a good idea these days, which Designveloper will promptly list below.

1. Young, highly educated, and willing to work long hours

“Vietnam has the highest-performing computer science students I’ve ever encountered,” said Neil Fraser, a software engineer who works for Google, which is owned by Alphabet Inc. Sixty percent of the people in Vietnam are under the age of thirty. This means that there are a lot of young people who are eager to learn new things and are willing to work long hours.

2. You save money when outsourcing to the top app development companies in Vietnam

Vietnam’s relatively low cost of labor is one of the main reasons why IT work is often sent there. In this area, your company won’t have to spend a lot of money to find quality app developers. The cost of app development in the U.S. is about 90% higher than the cost of outsourcing software development to Vietnam. Compared to India, it costs anywhere from a third to a seventh as much to make software in Vietnam as it does in India. These numbers make it clear why businesses should start thinking about Vietnam as a place to set up their offshore development operations.

3. Reliability is sought after in a rising market for app development

In Vietnam, the number of companies that specialize in developing websites and apps has grown over the past few years. This means that there are also more people working, and because there is so much competition, the quality of the work is also getting better consistently in order to catch the eye of potential partners. Due to the stability of the country’s social and economic systems, Vietnam is also a great place to invest, not just in app development but in many other areas as well.

5 Things To Consider When Finding App Development Companies In Vietnam

In fact, there is a pattern that everyone follows when looking for a good app development company. Concerning Vietnam, it is still important to pay attention to a few things that are common.

1. Do a lot of research

Before you can start the hiring process, you need to have a basic understanding of what an app developer does. What kinds of programming languages are used? How much do you think most things cost? Your level of understanding of the profession is directly related to how well you can talk about it in professional settings like meetings and interviews. 

2. Thoroughly study the company’s portfolio

By looking at the company’s portfolio, you can get a general idea of the work it has done. You can learn about the UX and UI skills as well as several domains. This lets you figure out if a certain app development company has the experience to make apps for your business domain. For example, Designveloper has a page dedicated solely to the types of services it offers as well as projects the company is handling.

3. Communication is key

If you can’t talk to each other clearly, the quality of your application will go down. Because of this, it’s important to put a lot of effort into getting along during the first meetings. In addition to their skills and experience, you should look at how well they get along with you and how well you both understand each other. Working with Vietnamese app development companies comes with the risk of a language barrier. Because of this, you should make sure that the staff has a good grasp of English before you start working with them.

4. Examine the post-launch support

Putting the app out there is not the last step, because it could still be changed based on users’ reactions. To make changes that make sense, you need the help of developers. These developers are also responsible for keeping the app in good shape. Because of this, app development companies that offer this service should be given more attention.

5. You need transparency

When you meet with app developers, be sure to talk in detail about the app’s idea and the people you want to reach with it. If you know what your company needs and wants, making an application will be a lot easier. Of course, first ensure that the app development company you’re employing and you are on the same page not only regarding your needs but also regarding language.

8 Tips on How to Increase Open Rate in Email Marketing

The statistics on Email marketing as an effective strategy are staggering. The return on investment alone is 4200%, and up to 64% of SMEs use it as the primary tool in client interactions. Email marketing is here to stay, and it is a personal, efficient way to communicate with brands and customers. Note that 80% of online marketers prefer email marketing over social media and other digital strategies. So how to increase open rate in email marketing?

The contention for many email marketing strategies is how to increase the open rate. The primary concern here is how many of your subscribers open the emails you send? Open-Rate is a factor used to determine the effectiveness of an email marketing campaign. You achieve this by calculating the percentage of subscribers who open specific email content. Open rate is a very critical metric affected by several influencing factors. Elements such as audience size, CTR, bounce rates, and other factors calculate the efficiency of your campaign.

What Do You Need to Know About Email Marketing?

Increasing the open rate depends on a variety of factors. Cybercrime has made customers very apprehensive about opening random emails. This issue has made email marketing substantially complicated.

Source: reliablesoft.net

For this reason, it is critical to ensure your email marketing is transparent. Focus on building trust by making your sign-up process risk-free. Links to your resource should also be worthwhile. You can use assets, such as a free website creator with numerous site widgets and design protocols. With such tools, creating a website or landing page is really easy. Email links to your website should also be encrypted to provide your customers with an extra layer of security. It is about creating a system that builds trust and improves conversion. 

There are several ways to improve your email open rate. Here is a list of 8 techniques to focus on in 2022.

How to Increase Open Rate in Email Marketing?

1. Domain Authentication

It is a way to validate email sender authenticity. This process helps verify you as a legitimate source and ensures your emails don’t end up as spam. Emails constantly directed to junk folders rarely get opened-this does nothing to improve your reputation and open rate. 

2. Personalize Your Emails

Sending the same email to a thousand receivers is the first step toward losing credibility. Note that customers have different demographics and hence, different needs. Aim to address customers differently according to specific requirements. Craft your emails for individual needs.

3. Invest in Quality Content

Content is a significant selling point in any business. Customers want value for money, and quality content is what you must provide. From the subject line to your last remarks, you need to b concise and engaging. It boils down to capturing your customer’s attention and proving you have something to offer. 

4. Timing and Frequency

The easiest way to get a high unsubscribe rate is to barrage customers with constant emails. No one likes a nag. Develop a system that evaluates your customers and the product you provide. Research into what time of the day people are active and build your strategy within this timeline. Check industry statistics on how and when experts send emails and how often. 

5. Subject Lines

A potential customer gets hooked on your email when they see an appealing subject line. Up to 67% of emails get opened because they have a catchy title. Whether you are offering great deals, free offers, or new products, your subject line needs to create a sense of curiosity. It does not matter if it is shocking, humorous, or plain-the subject line must pull your customers and make your email irresistible.

6. Use Emojis

Emails are no longer the formal, boring elements they used to be. Statistics show that emoji use in email marketing increases every year by as much as 800%. If your subject line has an emoji, you have a 60% higher chance of a conversion. Think about a 29% increase in unique CTR, lower bounce rate, and 44% increase in sales. While many people may still be apprehensive about emojis, they work.

7. Consult Your Subscribers

Increasing your open rate boils down to strategy. Don’t wear your subscribers out with constant emails or resend unopened ones. Be tactical in your approach. Ask your subscribers when they want to receive your emails and at what time. It is easy to become a nuisance. However, this technique will ensure you maintain a fruitful relationship with your customers.

8. Research The Market

Always ensure you understand the strategies competitors are using to maximize conversion. Evaluate what techniques work and which ones don’t. Establish a timeline for scrutinizing whether your current strategy works. Find ways to create anticipation and work on a game plan to solve subscriber problems.

Bottom Line

Digital marketers still rank email marketing as a top strategy with 80% of these marketers insisting it is effective. After knowing how to do it right, this technique is a guaranteed goldmine. Designveloper hopes this information can help you with the next email marketing plan! Besides this can help you answer the question “how to increase open rate in email marketing?“

What Is HTML?

HTML is the markup language used on the web, and it is used to make most of the pages you see online. But what is HTML, really?

In this article, Designveloper will give the most in-depth introduction to basic HTML that we can. Before we start, try not to get too scared. This guide is for anyone and everyone, no matter how much technical knowledge they have.

Are you ready to start getting acquainted with HTML? Let’s go.

What Is HTML?

HTML, or hypertext markup language, is a fundamental computer language that is used for the creation of websites. The knowledge of this language is an absolute must if you are thinking about pursuing a career in online design or development; nevertheless, even in other fields, such as digital marketing, even a basic understanding of HTML can be useful.

Markup languages like HTML are used to describe how your work is put together. HTML is made up of different parts called “elements”. You can use these elements to “wrap” different parts of the content to make it look or act in a certain way. With the surrounding tags, you can make text italic, change the size of the font, turn a word or image into a link to another page, and do a lot of other things to format it.

HTML is considered to be one of the three most important tools for building websites. 

1. HTML tells you how a website is put together, including how text, images, and other media will be shown on the page. 
2. Cascading style sheets, or CSS, decide how these elements look, including their colors, layout, and format. 
3. JavaScript makes it so that these elements respond in certain ways to what a user does.

The History Of HTML

As was already said, HTML is a type of programming language that is used to make websites. Its full name is “Hypertext Markup Language,” but people usually just call it “HTML”. HTML is a markup language that tells an internet browser how to display a document. 

Tim Berners-Lee was a scientist who worked as a contractor at CERN. In the late 1980s, he came up with the idea for a system that CERN researchers would use. In a document he wrote in 1989, he suggested a hypertext system based on the internet.

As a result, HTML was made by Tim Berners-Lee, who is well known for this. Tim’s idea for a document called “HTML Tags” in late 1991 was the first time that HTML was explained to the public. Consequently, HTML5 is the most recent version of HTML, and we’ll learn more about it in the next section.

The Many Different Versions

Since HTML was first made, many different versions of it have been put on the market. The following gives a quick overview of each of these versions:

HTML 1.0: The first version of HTML came out in 1991. It was called the “barebones” version of HTML. The first version of HTML was also HTML 1.0.

HTML 2.0: This version came out in 1995. After it was first used, it became the standard language version for making websites. HTML 2.0 could add features like form-based file uploads and form parts like text boxes, choice buttons, and so on.

HTML 3.2: The HTML 3.2 version was released by the W3C at the beginning of 1997. This version added more options for form elements and made it possible to make tables. This version also had the ability to build tables. It can also host a website with complicated mathematical formulas on it. It wasn’t considered an official standard for any browser until January 1997. Even now, support for it can be found in a large number of browsers.

HTML 4.01: HTML 4.01 came out in December 1999 and is a pretty stable version of the HTML language. HTML 4.01 was also used to make the World Wide Web. This version is the official standard at the moment, and it has better support for stylesheets (CSS) and better scripting for a wide range of multimedia features.

HTML5: This is the name for the most recent version of the HyperText Markup Language. It is also just called HTML5. In January 2008, the first draft of this edition was shown to the public. The World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG) are both important groups that are working on the HTML 5 version, which is still being improved.

An Example Of HTML

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>My first heading</h1>
<p>My first paragraph.</p>
</body>
</html>

Explanations

<!DOCTYPE>: This is a command that tells the browser what version of HTML is being used or what kind of document is being shown.

<html>: This tag tells the browser that the file being looked at is an HTML file. The text that is between the html tags describes the web document. With the exception of the <!DOCTYPE> tag, it holds all of the other HTML elements.

<head>: It should be the first element inside the html element, and it should hold the metadata. The full name of the head element is “head” (information about the document). Before the body tag can be opened, it has to be closed.

<title>: The title of an HTML page, which is shown at the top of the viewer’s window, is what the title> tag is for, and it does exactly what its name says. It needs to be put inside the head tag, and as soon as it’s there, it needs to snap shut.

<body>: The text inside the body element is used to explain to the end user what is in the main body of the page. This tag is where the HTML document’s main text content can be found.

<h1>: The text inside a h1 element is used to describe the first level heading of a webpage.

<p>: On a webpage, the text inside the p element is used to describe the paragraph.

7 Main Differences Between HTML And HTML5

The biggest difference between HTML and HTML5 is that HTML5 now lets you use new types of form controls. HTML5 also added a number of semantic tags, like “article,” “header,” and “footer,” which describe the content in more detail.

1. Browsers

HTML works well in older browsers, while HTML5 works well in newer browsers and also supports older browsers. This is yet another way that HTML and HTML5 are different.

2. Type

Also, HTML is a language with less detail than HTML5, which is a language with more detail.

3. Vector Graphics

Another difference between HTML and HTML5 is that HTML5 can handle vector graphics, but HTML cannot. HTML can make vector graphics work with the help of other software or plugins. On the other hand, vector graphics are an important part of HTML5.

4. Multimedia

It is hard to add multimedia to HTML and hard to keep track of it once it is there. HTML5 makes it easy to add and manage multimedia content (such as audio and video, among other formats). Because of this, a big difference between HTML and HTML5 is the use of multimedia elements.

5. Help With Off-site Storage

Also, HTML and HTML5 are not the same because HTML doesn’t support offline storage. This is another difference between the two. HTML doesn’t have very good support for offline storage, unlike HTML5, which has great offline storage support.

6. Help With Web Sockets

Web sockets are not currently supported by HTML. On the other hand, HTML5 supports web sockets, which allow communication in both directions. The difference between HTML and HTML5 can also be seen in this way.

7. Geolocation

HTML doesn’t have geolocation, but HTML5 does.

The 7 Features Of HTML

1. Easy To Learn

It’s an easy language to learn and understand. It’s not hard to understand, and it’s simple to adapt to new situations.

2. Effective Presentation

Using this language to make a good presentation isn’t too hard because HTML comes with a lot of tags that can be used to change the way things look.

3. Flexibility

Since it’s a markup language, it gives you a flexible way to make web pages with text and images, which you can do along with the content. This can be done by putting the two things together.

4. Link Optimization

 It makes it easy for programmers to add a link to a web page (using the html anchor tag), which makes the user want to look around the website more.

5. Platform-Independent

Because it can be shown on any platform, including Windows, Linux, and Macintosh, it is seen as independent of any platform.

6. Multimedia Elements

 It makes it easier for the programmer to add multimedia elements to web pages, such as pictures, videos, and sounds. All of these things help make the website more interactive and appealing to look at.

7. Case-Insensitive

Since HTML is a language that doesn’t care about the case of its words, we can use either lowercase or uppercase components in our documents.

How Does HTML Work?

HTML is like other programming languages in that it is made up of a series of commands and blocks of text that are then turned into what the user sees. This is done so that web browsers can understand HTML. 

If you are using a desktop or laptop computer and want to see what the HTML code on this page looks like, you can do so by right-clicking anywhere on this page and choosing “View Page Source” from the context menu. This is the right way to get to the HTML code of a page (the option may vary depending on your browser). When you click on it, you should be taken to a big block of text that has code in it.

As we’ve already talked about, HTML can tell a browser where to get more resources and what to do with the content on a page by using a series of tags. Some of these instructions can tell the browser where to look for more things to load. Even though there are more than 100 HTML tags that can be used, most websites only need a small number of them to work as they should.

Top 5 HTML Practices

1. Make a list of all the pages with URLs that are clear and full of keywords

If you use HTML, you can change the URL of your pages by hand. Use this to your advantage by making websites that are easy to understand not only for people but also for search engines. Make sure that the words “swimming trunks” are in the URL of a page about swimming trunks, for example. This may seem like a no-brainer, but there are a lot of URLs out there that use letters, words, and other things that don’t mean anything and hurt the organic SEO of a page.

2. Use title tags that mean something

Using the title> tag, you can give a web page more meaning and make it easier for search engines to find. For example, the text inside the title> element is shown on the page that shows the results of a Google search, as well as on the user’s web browser bar and tabs.

3. Write unique content full of keywords

By using keywords and keyphrases in the body text in a natural way, you not only send good signals to search engines but also let readers know they are in the right place. As a general rule, keywords should be used a few times throughout the content, sometimes making up 1% to 2% of the text on a page. To make search engine optimization better, keywords should be used. This means that between one and two of the 100 words on a page should be keywords.

4. Write consistent code

A code base that is neatly written and indented correctly shows that you are a professional and care about other people who may need to work on your code in the future. It’s a good idea to start your work with clear and correctly indented marks to make it easier to read.

5. Link to external and internal pages

You can show Google that a certain page is linked to the rest of your site by linking to other pages on your site that are about the same subject. It also gives readers the option of clicking through to other interesting parts of your website, which can make their reading experience much better. By using this search engine optimization (SEO) strategy, which shows search engines and readers that you know what other information people might be looking for on the web, you can increase the number of people who visit other pages on your website.

If you put external links in your content, both your readers and search engines will be able to tell that the information you provide comes from credible, authoritative, and trustworthy sources. Though you may pass link equity to them from your site, linking to external sources whose domains end in.gov or.edu is a great way to show that you only trust the most trustworthy organizations, which will make a reader more likely to trust you. Even if you pass link equity to them from your site, linking to outside sources whose domains end in.gov or.edu is a great way to show that they are trustworthy.

The 4 Programming Languages Used by Top Companies

Just imagine when you have a good idea but executive poorly because of the wrong stacks. What could be more painful than this scenario? People at Designveloper understand your struggle. So this article will introduce 4 major programming languages used by top companies worldwide.

Since the number of new programming languages saying hello to this world is increasing dramatically. It’s getting harder for coders and website development companies to choose the perfect one to adapt.

What Programming Languages Used by Top Companies?

What programming language do big companies use?

Since the number of new programming languages saying hello to this world is increasing dramatically. It’s getting harder for coders and website development companies to choose the perfect one to adapt. Let’s start with…

1. JavaScript

JavaScript is a programming language released in the late 90s. People and different website development companies use this one to program the behavior of various environments such as web pages, desktop, and server programs. Besides that, some databases (eg. MongoDB, CouchDB) also embrace JS as their programming language. 

With JS, developers can do everything related to web page manipulation as well as interact with the user and the webserver. 

After more than 20 years of continuous development, JS has become the most popular programming language according to Stackoverflow. That said, this programming language is used and trusted mostly by large companies including Paypal, Netflix, Uber, etc. This happens due to its various benefits when applied to a certain project, especially web app ones. Below are several reasons why we should practice it a lot:

• Universal support.
• Imperative and structured.
• Dynamic.
• Prototype-based.
• Functioned.
• Miscellaneous.
• Functional.
• Delegation.
• Vendor-specific extension.

And you know what, up until now, JS is the only language offering those advantages at the same time.

Who is using JavaScript right now?

Let’s continue with some trends related to this language in 2019: 

• Vue.js is getting more popular every day. There are 30,000 questions regarding Vue.js on Stackoverflow. On top of that, 2 of the most well-known companies – Gitlab and Alibaba – are using this one.
• Angular is one of the most common JavaScript technologies on Stackoverflow.
• Website development companies are moving away from REST API and start paying more attention to GraphQL since this new query language is able to solve several issues that REST API can’t.

2. Python

Obviously, you don’t even need to be an expert to hear of Python. But let us introduce it anyway. Python is an objective-oriented programming language released in 1991 by Guido van Rossum.

At the moment, Python is mostly used in large projects by many website development companies, some of the most famous companies practicing this language are Google, Wikipedia, Facebook, Amazon, Reddit, etc. Developers also write AI projects in Python alongside libraries like TensorFlow, Keras, etc.

So the million-dollar question is “Why are there so many using Python?”.

There are many to list. First off, this programming language becomes a beloved one among others due to its ability to work across various platforms (Windows, Mac, Linux, etc.) 

Furthermore, many experts suggest newbies use Python since its syntax is similar to the English language. People develop this language to slither readability, you know. 

However, Python is also well-known because it manages to handle big data and perform complex mathematics.

The benefit of Python

We need fewer lines of code to develop a certain project when using Python than in some other languages. The last major advantage of Python is that code edited in Python can run as soon as it is written.

In other words, when coding in Python, developer productivity is increased in comparison with C and Java. Besides, Python enables us to write clear and logical code easier. Nevertheless, since there is no compilation step, the development cycle including editing, testing, and debugging runs faster. This helps web development companies deploy code constantly. 

Regarding Python development’s trends in 2019, we have these pieces of news for you:

• Developers around the world are embracing Python for data analysis, web development, DevOps, and machine learning.
• The three most common Python frameworks for web development are Django, CherryPy, and Pyramid

3. C++

In 1979, Bjarne Stroustrup developed a general-purpose programming language dubbed “C with Classes”. Then later, people call its name C++.

At first, people developed to solve various concerns of large-scale projects. In short, C++ is an object-oriented language and it’s also an extension of C. We as developers can use this language for system/application software, client-server application, drivers, and especially embedded firmware. That’s why C++ is also called the “Swiss pocket knife of languages”.

Due to the fact that this language embraces the ability to adapt to this everchanging industry, C++ continues to be one of the most popular programming languages with a lot of website development companies. 

The main reason why developers don’t give up this 40-year-old programming language is that once written correctly. It always maintains a high performance. Besides, C++ can interface well with other languages. The ability to easily put data into a database or pull it out is another benefit when using this language to develop many types of projects. And maybe you have already known, that a lot of game developers keep on adopting C++ because it can display high-speed graphics in games and videos.

According to Paul Richard on Tutorials Point, C++ is a language that is statically typed, compiled, general-purpose, case sensitive, free form, procedural programming, etc. Furthermore, compared to some other languages, C++ is fast and good for memory.

On the one hand, C++ generates effective and quality code. In other words, it runs very quickly. And you know what? Many programmers from different website development companies believe this is one of the fastest languages to use. On the other hand, C++ owns a huge ecosystem of frameworks, libraries, and tools.

4. Java

Java is another object-oriented programming language in 2019. It became the most popular programming language with a community of 10 million developers according to Github. 

Steve Zara, a 40-year experienced Java engineer put it, after more than 20 years since the day it was released. Java is still continuously evolving thanks to the combination of stability and innovation.

To some extent, website development companies pick up Java since they can write and edit code in this language effortlessly. Furthermore, Java is powerful across platforms that can be used for:

• Mobile applications.
• Desktop applications.
• Web applications.
• Web servers and application servers.
• Games, etc.

In addition, Java was built to execute a high level of security. That said, this language is one of the most secure ones to use by many website development companies up until now. However, the main reason why this programming language is popular is platform independence.

Some outstanding features of Java are 

• Simple: it’s easier to use Java since this language has removed all the complexities such as pointers, and operator overloading.
• Portable: we can write any applications on one platform but it still exports to another platform.
• Object-oriented: with this language, anything could be considered an “object”.
• Secured: we can convert every line of code into bytecode after compilation. Obviously, a human cannot read these kinds of things.
• Dynamic: Code written in Java can adapt to an evolving environment that supports dynamic memory allocation.
• Distributed: This language includes a feature that can create distributed applications.
• Robust:   Java owns a strong memory management system, it can eliminate a lot of errors.

In addition, coders can build applications that run offline or can be distributed across servers and clients in a network.

How Many Programming Languages?

This is one of the questions I aim to answer with CodeLani. I am building a comprehensive database of programming languages. The number of programming languages in the world depends on the rules you establish for deciding whether or not a language counts.

1. Wikipedia – 700

Wikipedia has a list whose goal is to include “all notable programming languages in existence”, that currently lists over 700 programming languages. Wikipedia’s list excludes certain types of languages such as markup languages.

2. TIOBE – 250

The TIOBE index is one of the best lists of popular programming languages and monitors ~250 popular programming languages. TIOBE tracks a programming language if it passes 3 tests: it must have its own Wikipedia page, it must be Turing complete, and a Google search for it must return over 5,000 search results.

3. FOLDOC – 1,000

FOLDOC, a 90’s era online dictionary of computing, lists over 1,000 programming languages, though that includes aliases.

The Most Secure Programming Languages

A new report from the open-source security company WhiteSource asks, “Is one programming language more secure than the rest?“. Across the seven most widely-used programming languages, here’s how the vulnerabilities were distributed:

• C (47%)
• PHP (17%)
• Java (11%)
• JavaScript (10%)
• Python (5%)
• C++ (5%)
• Ruby (4%)

The report then concludes that “the Winner of Most Secure Programming Language is…no one and everyone…! It is not about the language itself that makes it any more or less secure, but how you use it. If you are mitigating your vulnerabilities throughout the software development lifecycle with the proper management approach, then you are far more likely to stay secure.”

A Conclusion of Programming Language

Every programming language has its own benefits and advantages. As a result, your mission is to seek what is best for your future project. But hey, if you are still in the loop, let Designveloper give you a hand. Tell us your ideas and we will realize them for you!

What Is React Native?

React Native has been one of the most talked-about topics in the field of mobile app development for the past few years. It caused such a stir in the tech world because it made it possible to make mobile apps for both iOS and Android at the same time. But what is React Native, really?

In the first part of this article, let’s learn more about what React Native is and how it works.

What Is React Native?

The Definition

JavaScript is the framework for React Native, which lets developers make real mobile apps that run on both iOS and Android devices. It is built on React, which is a JavaScript package that Facebook uses to build user interfaces. However, it is designed for mobile platforms instead of browsers. To put it another way, web developers can now make “native” mobile apps using a common JavaScript librar. Also, most of the code you write can be used on both Android and iOS. This makes it easy to make apps for both platforms at the same time using React Native.

React Native has been very successful for a number of reasons. Businesses that use it can write code once and then use it to power their iOS and Android apps. They save time and money by doing this. This makes a big difference in how much time and resources are used. Second, the mobile framework was built on top of React, which had been very successful. Third, the framework allowed front-end developers, who had only been able to work with web-based technologies up until that point, to make strong, production-ready apps for mobile platforms.

The History Of React Native

Mark Zuckerberg said in 2012 that the biggest mistake his company had made was betting too much on HTML. After the company switched to HTML5, the mobile app for Facebook’s mobile version stopped working and data was collected slowly. He promised that Facebook would soon make the mobile experience better.

At Facebook, Jordan Walke found a way for a background JavaScript thread to make user interface elements for iOS. This discovery eventually led to the creation of the React web framework. They decided that an internal hackathon would be the best way to improve this prototype.

After working on it for a few months, Facebook released the first version of the React JavaScript Configuration in 2015. Christopher Chedeau gave a technical talk where he talked about how React Native is used to make Facebook’s Group App and their Ads Manager App.

This is how React Native got started. At first, it was only made for iOS, but Facebook quickly added support for Android and then made the framework public in 2015. After only three years, it was already the second most popular project on GitHub. In 2019, it was still strong and came in sixth, with over 9,100 contributors.

React vs. React Native

Both React and React Native are made up of mixtures of JavaScript and JSX. What makes them different is that JSX components use different syntax to render elements, while React and React Native use the same syntax. React uses HTML and CSS, while React Native makes it possible to use native user interface elements on mobile devices.

Facebook solved scalability problems using React, which was added to the Instagram app after in 2012. React led naturally to the creation of Facebook’s React Native, which is powered by React and was made by Facebook. It is a mobile framework that lets developers use JavaScript to make apps that work as well as native apps. In general, React is for building websites, while React Native, which doesn’t need HTML, is for making mobile apps.

3 Advantages Of React Native

There’s no getting around the fact that React Native is one of the most popular front-end frameworks right now. If you’re still not sure if you should use this framework for your project, let’s talk about some of the reasons why you should.

1. Code Reusability

One of the best things about the framework is that it lets you use code you already have. This is a good sign that your applications will work well on many different platforms. Studies show that 90% of the native framework could be integrated so that the code could be used on many different operating systems.

If both your web app and your mobile app use React Native, you can reuse the code. This not only cuts down on the time for building the software, but it also uses parts of the open-source library that have already been built.

2. Knowledge Sharing

Using the framework’s features can cut down on the amount of time and money for making mobile apps. Software developers who can write React code can now make apps for the web, iOS, and Android.

Because engineers don’t have to be “silo” based on the target platform they are developing for, React Native lets your team iterate more quickly and share knowledge and resources in a more efficient way.

3. Pleasant Developer Experience

If you’ve developed for mobile platforms before, you might be surprised at how easy it is to start using React Native. The team worked hard to build powerful developer tools and useful error messages into the framework. As a result, using powerful tools is a natural part of the development process.

With React Native, you don’t have to rebuild your app for changes to take effect. Instead, you can hit Command+R to refresh your application like you would any other web page. This is because you don’t have to rebuild your app to see the changes you’ve made. The time you spend waiting for your app to develop can add up quickly, so React Native’s fast iteration cycle is beneficial.

Also, the framewor gives you access to advanced tools for debugging and lets you report errors. If you know how to use the developer tools that come with Chrome or Safari, you’ll be glad to know that you can also use them for mobile development. In the same way, you can use any text editor you want to write JavaScript. React Native doesn’t require you to use Xcode to write for iOS or Android Studio to build for Android.

When Should You Use React Native?

When making an app for both iOS and Android, it should go without saying that you should use React Native. If you already know how to use JavaScript, this choice will be even better for you. In the best use case, using it is more efficient, easy to use, and cost-effective. Both apps for iOS and Android require a smaller number of developers to work on and in a much shorter amount of time.

React Native is a safe choice due to the support it has. The framework is supported by a community of people who work together to make it better every day. Also, because Facebook supports React Native, it will get regular updates. At the moment, it has gained a lot of support and a large number of Fortune 500 companies are taking advantage of it.

Also, there is no other framework that can compete with React Native when it comes to the quality of the user interface (UI) and user experience (UX) In some situations, applications made with this framework work better than those made with native programming.

What Is React?

React is one of the most popular and widely used tools for building modern web apps right now. At least 68.9% of the developers who work on React say they enjoy using this library and plan to keep doing so. As web development is the backbone of most businesses nowadays, it’s important for us to know exactly what React is.

Let’s start this part of the post by talking about the definition of React.

What Is React?

The user interface development library called React is written in JavaScript. It is run by Facebook in collaboration with an open-source developer community. Even though React is a library and not a language, it is quite popular in the field of web development. The library appeared for the first time in May 2013, and since then it has become one of the most popular front-end libraries for web development.

A library is not the same thing as a development framework, which is a set of ideas and a plan for addressing and meeting the needs of development. A library is simply a collection of books and other materials. When building an application with React.js, you can choose from a number of different frameworks. Some examples of these frameworks are Create React App, Shards React, Redux, and React DnD.

React offers more than just UI. For example, it has extensions like Flux and React Native that help support the application’s overall architectural components.

5 Things To Like About React

The React front-end development framework is now more popular than any other front-end development framework. This could happen for a few different reasons.

1. React Is Easy To Learn

Angular and Ember are “Domain-specific Languages,” which means that they are hard to learn. React, on the other hand, is easy to understand for anyone with even a basic background in programming. All you need to know to use react is the basics of CSS and HTML.

2. Improved Performance

Since React uses Virtual DOM, making web apps is faster because of it. Instead of updating all the components again, as most web apps do, Virtual DOM looks at the previous states of the components and only updates the parts of the Real DOM that have changed. Traditional web apps, on the other hand, update all of the parts at the same time.

3. High Testability

It’s very easy to test applications made with ReactJS. Since React views are functions of the state, we can change the state in ReactJS view and then look at the output and any actions, events, functions, etc. that come from that.

4. Reusable Components

Components are the basic building blocks of every React app. Most of the time, a single app will have many different components. These parts have their own logic and controls, and they can be used over and over again in the app. Because of this, a lot less time is necessary to design the application.

5. One-way Data Flow

React follows a data flow in only one direction. This means that when making a React project, developers usually put child components inside their respective parent components. Since data only goes in one direction, it is much easier to fix bugs and figure out where a problem is in an application.

The 3 Significant Features Of React

React comes with important features that make it attractive to JavaScript developers. One of these is the availability of reusable React library code, which speeds up development and makes it less likely that mistakes will exist in the code.

1. JSX

Instead of the more common JavaScript, JSX is for creating templates in React. JSX is a simple JavaScript add-on that makes it possible to quote HTML and render subcomponents using HTML tag syntax. We use JavaScript to turn the HTML syntax into calls to the React Framework. We can also write in the standard JavaScript language.

2. Virtual DOM

The Real DOM is what the Virtual DOM in React is based on. The Virtual DOM is a lighter version of the Real DOM. Real DOM manipulation is much slower than virtual DOM manipulation. When the status of an object changes, Virtual DOM will only change the representation of that object in the real DOM, not all of them.

3. Extensions

React can be used as a user interface (UI) framework, but it also has a number of add-ons that allow it to be used for the whole application architecture. It provides server-side rendering and makes it easier to build mobile apps. You can add to React in many ways, such as by using Flux and Redux.

Common Threats To Watch Out For

1. Cross-site Scripting (XSS)

The act of putting a malicious script into the source code of an online application is X-site-stuffing, or XSS for short. This script is picked up by the browser, which thinks it is safe, and then the bad code is run as part of an application. If an XSS attack works, the attacker might be able to steal user passwords, get sensitive data from the app’s pages, send requests to the servers, and do other bad things.

2. Distributed Denial of Service (DDoS)

DDoS attacks flood a web app’s infrastructure with more users than it can handle, which makes the app crash. Their goal is to stop an application from working and make it inaccessible to its users. Some of the most common ways to do a distributed denial of service attack are with UDP, ICMP, SYN, and HTTP request flooding. An attacker will try to use up as many resources as possible, like memory and CPU processing time, because a server and firewall must respond to each request.

3. XML External Entity Attack (XXE)

Most of the time, this kind of React attack is made on a text-based language called extensible markup that is used by a web application. The attacker falls into the extensible markup text-based language (XML) parser to turn XML into readable code. Even though the language is used during the conversion process to store and unify the data, XXE is still put into the system. To avoid this kind of vulnerability, you should store any sensitive data in JSON format and use SAST tools to find any XXE code in your apps. You should also keep your system up-to-date.

4. Cross-Site Request Forgery (CSRF)

In this type of React cyberattack, the person who did it gets the user to do something on the web app that the attacker wants. This may involve the user sending money or agreeing to do something. Social engineering is the name for this kind of cyberattack. The main reason why people do things that are bad for themselves is how the bid is made. In fact, many of these bad requests come with the help of the programming language JavaScript to trick the user into falling into a trap. There are things that can be done to protect against this, like making sure that CSRF tokens are read from cached apps. In contrast, the server should be issued an authenticated request in order to permit only relevant headers.

Other types of cyberattacks include SQLi, CSV injection, arbitrary code execution, Zip-Slip arbitrary file write via archive, unsecured randomization, resource downloaded using an insecure protocol, and many more. Most cyberattacks take one of these four forms.
