In fact, As of March 2019, over 41 million mobile messages are sent in an online minute. 

This brings us to the next questions: i.e. what makes the best chat app and what are the best languages to build a chat app. 

This article is going to look at white-label chat apps and review the best languages to build a chat app. It will cover preferred languages to build the best chat application and the best ones to make sure they are secure messaging apps.

What is White Label Chat App?

A White Label chat platform would be the best approach to building a chat app. This is because a White Label Chat App does not provide any vendor-specific branding for example the vendor’s domain or logo. It also allows a host of customisation like adding one’s own logo, and colours, creating a separate messenger that is different from others as well as being easy to publish on Google Play or the App Store. This makes a White Label chat platform the preferred solution to build an online chat platform!

Choose the Best Language for Chat Application

One needs to consider the multiple kinds of languages available that suit individual needs before choosing the best.

Languages are not only decided by whether the requirement is to build a chat app for Android, iOS, the Web, or cross-platform, but also by whether they will be used to build the chat platform’s front end or back end.

Front End vs Back End Programming Languages – What are they?

Very simply, the front end is the UI (User Interface) of the program. Therefore, this is what the customers of the app will interact with the most. The front-end programming language is used to create the look and feels when one builds a chat app. 

Similarly, the back-end language is used to do everything that the end-user does not interact with and is used to build the server-side. The back-end programme is responsible for having the logic in place that makes requests put in by the customer a reality.

Best Front-End Programming Languages to Build a Chat Platform

Since the front end is geared towards user experience, the kind of program used to build the chat app depends on whether it will be used on Android, iOS or across a variety of them. Here are the best languages to use across all these to build a chat app.

Best Android Programming Languages to Build a Chat App

1. Java

Java has been the language of choice since Android made its official debut. In fact, most of the programming languages for Android are based in some form or the other on Java, therefore is almost a no-brainer when trying to build a messaging app.

Some advantages of using Java

• Created for app development and therefore not dependent on particular hardware or software and is applicable across most OS.
• Relatively easy to learn
• Versatile and scalable to be used across mobile, desktop and largescale industry servers as well as the cloud.
• Object-oriented and built to make modular components and reusable code.

2. Kotlin

Kotlin is a much newer program that came out in 2016. This is also because while Java is object-oriented, Kotlin is both object-oriented and has functional programming features. This makes it a great choice when looking to build a messaging app.

Some advantages of using Kotlin:

• Kotlin is much easier to read and write leading to error-free code
• Kotlin is null safe by default 
• It is an interoperable language and can be used with Java without errors
• It is immutable and lowers the chance of developer errors

Now that we have seen the languages available to build the best chat app for Android, let us look at what it looks like for iOS.

Best iOS Programming Languages to Build a Chat App

1. Objective C

Objective-C is one of the oldest programmes created by Apple. It is based on the C programming language with added object-oriented capabilities

Some of the advantages of using Objective-C are:

• Objective-C supports older versions of iOS and is suited for universal projects
• It is a stable language and does not need newer updates or versions.
• Well-tested language with millions of code lines written
• Object-Oriented Programming with modular build and reusable code.

2. Swift

Swift was introduced by Apple in 2014. Swift has a much easier syntax to work with. If one is looking at building the best chat app for iOS, Swift is a great choice because:

• A simple language leads to reduced development time and error-free code.
• It is open source
• Interoperable with Objective-C making integration easier
• Runs much faster than Objective-C

Best Web Programming Languages to Build a Chat Platform

Unlike the requirement to build a chat app for Android or iOS, it is slightly different for the web. That said, there are a few options available there too

1. Javascript

Plain vanilla Javascript is always an option to be used. Considering it is more than 20 years old and is so popular, it does have a few benefits too.

• It is supported by many browsers, so it is largely browser independent
• Easy to write code without the use of a particular program or tool
• Relatively easy to learn
• Very popular

2. Angular

Angular is an open-source framework that was developed by Google. It has a standardized application structure that works well. Some of the advantages of using Angular are:

• It is easy to learn
• It has a large developer community making it easy to reach out for support
• Supported by Google and therefore has gained significant credibility
• Supports Single Page Applications helping with a faster website transition.

3. React

React is one of the most popular libraries used for the front-end development of apps. Given that it is so popular, there are various advantages to using it:

• Ability to reuse code thanks to component architecture.
• Ample developer support
• It reduces page loading time 
• Can easily transition to mobile development with ReactNative

Best Cross-Platform Applications Programming Languages to Build a Chat App

Finally, we come to what languages can be used while building the front end for the best chat app that can be used across the different OS

1. React Native

This is a framework built upon React and is built for native platform APIs. The advantages of using React Native are:

•  Code is reusable across platforms
• Can access native functionality directly from Javascript
• Similar architecture to React
• Faster development and deployment time

2. Ionic

Ionic is a unique and interesting framework because it can be used across platforms like React, Angular, or even Javascript. Some of its advantages are:

• Has a very large developer community
• Flexible framework
• Can be used with a multitude of platforms
• Highly customizable themes and components

3. Capacitor

The capacitor was created by the makers of Ionic but both can be used independently as well. It has a lot of advantages like:

• It gives the developer a pure web development experience
• Provides PWA (Progressive Web App) support
• A very strong and growing developer base
• A very strong adoption at the enterprise level

Best Back-End Programming Languages to Build a Chat App

Now that we have discussed the options one has for Front-End, we now look at the options for back-end development. Since back-end development is not platform or OS-dependent, this brings the variables down.

1. Erlang

Erlang is a language that is designed for many processes running parallelly. This makes it very suitable when looking to build the best chat app. Its benefits are:

• Scalable both by adding more cores or new machines
• Its concurrency design thanks to lightweight threads makes it very reliable
• It is process-oriented
• Has the ability to update/upgrade the code live during operations

2. Javascript

When used for back-end development, Javascript runs through an environment called Node. As in front-end development, there are benefits to using Javascript here too.

• Processing is very fast
• Relatively easy to learn 
• Very popular with ample access to developer support
• Offers non-blocking I/O and asynchronous request handling

3. GO

Go, also known as Golang was created by Google. Some of its advantages are:

• It is very fast
• It is object-oriented
• Offers concurrency
• Is open source

Which Programming Language to Choose?

As one can see, to build a secure messaging app, there are multiple options available. Take the illustration below as a guide to choosing Front-end languages.

To choose a back-end language, it is best to go with familiarity and skill rather than a particular language’s features.

Conclusion

 Hopefully, this guide has helped ease apprehensions and doubts about open-source object-oriented building a chat platform. The best way forward would be to understand your specific case and project requirements and use this guide to decide the languages and framework to use
