Why use React Native for your Enterprise Mobile App Development?

meta_prasad — Wed, 12 Apr 2023 12:45:50 +0000

React Native is a JavaScript-based application development framework that allows developers to build an application that works on both Android as well as iOS platforms. React Native uses a single coding language that is recognized on iOS and Android platforms. Before the introduction of this cross-platform mobile app development framework, developers had to create a separate version of the app for both operating systems. This not only increased the time, but also the cost required for app development.

React native developers write an application once and port the code to another major platform, offering a fully native experience for app development. But the question is whether React Native is viable for Enterprise Mobile App Development.

Let's first understand enterprise mobile applications and the requirement to develop them, after which we can see how React Native helps build a great native experience for mobile platforms.

What is Enterprise Mobile App Development?

Large organizations need enterprise mobile app development services to ensure that they are connected round the clock. They need a trusted, portable, scalable, and engaging platform for stakeholders. The platform should enable a person working in the field to get easily connected with his/her colleague sitting in the office.

Most enterprise users like to use the application on mobile devices. However, some might require to use it on their laptop. As every company looks for their application to be built within a short period and without incurring huge expenses, it is important to adapt to a modern approach to enterprise mobile app development as it helps achieve both the goals. Cross-platform mobile app development is the best way to create and deploy a multi-device app, which runs on a different platform with a single code base.

How React Native meets the requirements of Enterprise Mobile Application Development

Large organizations or enterprises have multiple requirements to be able to exchange data from a mobile device. This is where React Native is useful.

Let's see what comes with the React Native framework that helps build amazing iOS and Android applications, which run on almost all devices of all sizes.

1. Readability

React Native is a tool created by Facebook that is favored by developers who want to make great-looking interfaces for apps that can run on both iPhones and Android phones. It was first used to make apps for iPhones, but now it also works well with web and other components.

React Native creates a “bridge” to the language of the device it's running on, which means apps built with it work well and have the same benefits as apps made specifically for that device, whether it's an Android, iPhone, or Windows laptop.

2. Cross-Platform Development

Enterprises prefer cross-platform mobile app development as it eliminates the need for separate Android and iOS teams, which is resource-intensive, time-consuming, and requires a budget for development and maintenance on two platforms.

React Native, on the other hand, allows developers to use a single code base and deploy it on both android and iOS platforms. Moreover, it allows developers to save time to push new releases, bug fixes and security features through a single code base that saves a lot of time to focus on innovation instead of maintaining apps on multiple platforms.

3. Open-source

React Native is an open-source framework. It provides free and easy access to all advanced features to build mobile applications. Companies can save costs and maximize their ROI with this open-source framework. The savings can be used to hire good app development teams.

4. Supports External Plugins

Plugins not only speed up app development processes but also add value to the application. Developers no longer need to build and customize apps from scratch if they are using React Native.

The framework supports several popular plugins that come with certain features, which are easy to integrate with the app. It helps developers in saving time which they can utilize to create only those parts of the app, which are unique to the application. The availability of a range of third-party plugins simplifies the entire app development process.

5. Evolving Community

Ranked third in Git's list, React Native has a constantly evolving community helping the framework grow through regular contribution from the members. On the other hand, since it is a product of Facebook; it gets social media support as well.

The best minds across the world are working on the platform to improve its capabilities, fixing issues, improving features, and helping developers solve complex problems related to any project. Having the strong support of an active global community is React Native's biggest USP.

6. Programming Language

Finding the right talent in the development team is crucial to ensure product innovation and success. React Native framework is JavaScript-based, which is a general-purpose coding language. So, it is relatively easy to find an app developer for React Native projects and establish a team.

There are certain differences between web-based JavaScript and mobile-based react native code, but these commands are easy to learn.

Summing Up

The aforementioned benefits indicates that developing React Native applications is a viable option for enterprises. Continuous innovation and contribution to the growth of the framework is yet another reason that lets you stay ahead of the curve by leveraging advanced features, thus decreasing the time and costs involved in mobile app development.

On top of that, it offers a seamless experience to users on different operating systems and devices of different sizes.

An Overview of React Native CLI

meta_prasad — Tue, 28 Feb 2023 13:15:44 +0000

React Native CLI, or Command-Line Interface, is a text-based interface that enables users to interact with software and operating systems through the use of commands. The React Native CLI consists of a set of commands specifically designed for use with React Native projects.

Initially, the CLI was integrated into core React. However, in 2018, Facebook made the decision to re-architect React Native in an effort to address persistent issues. As part of this effort, the React Native CLI was shifted to @React-Native-community/cli to create a "lean core" for React. This involved moving some of the basic functionality to separate packages, which helped to make React processing more efficient and faster.

There are currently three different CLIs commonly used in React Native development, but the latest and officially recommended CLI is @React-Native-community/cli. This CLI is designed to help developers create high-quality React Native applications with ease, making it an essential tool for React Native development.

Commonly used CLIs

1. @React-Native-community/cli

The @React-Native-community/cli is the official and current Command-Line Interface for React Native development. Upon downloading React and React Native, the CLI tool is automatically included as a dependency, providing developers with all the necessary tools for their projects. This CLI offers a convenient and efficient way to manage React Native projects, from setup to deployment, with its user-friendly commands.

2. React-Native-CLI

The React-Native-CLI, while still available, is considered a deprecated or legacy version of the Command-Line Interface for React Native development. It is no longer required, and if a developer chooses to use it, they must install it globally on their system. Developers are encouraged to use the latest and officially recommended CLI, @React-Native-community/cli, for the best results in their projects.

3. Expo-CLI

The expo-cli is the Command-Line Interface for the expo tools, which must be installed globally using the command "npm install expo-cli –global". This CLI provides a distinct set of commands, separate from the other React Native CLIs. For instance, to create a React Native app using this CLI, a developer must use the command "create-React-Native-app".

See the screenshot for reference.

4. Standard React-Native CLI

The Standard React-Native CLI, also known as the @React-Native-community/cli, is the officially recommended Command-Line Interface for React Native development. It offers a streamlined and efficient way to manage React Native projects, from initial setup to deployment, with its simple and intuitive commands. The Standard React-Native CLI is a critical tool for any React Native developer, providing a reliable and user-friendly way to interact with their projects.

New CLI Commands

Now, the fresh and new @React-Native-community/cli provides users different helpers and tools in the form of commands for React Native project. Let’s take a look at them!

Syntax:

Line starts with npx React-Native or React-Native.
Commands are written ahead of React Native. e.g., npx React-Native .
Some commands are separated by hyphen e.g., run-android.
Options follow the commands npx React-Native
Options can take arguments such as npx React-Native

Let’s dive into these commands one at a time.

Upgrade React Native:

npx React-Native upgrade

To install npm and npx:

npm install –g npx
npm install –g npm@latest

Display list of all commands:

npx React-Native -h
npx React-Native -h

Get version info of operating system:

npx React-Native info

Installing projects:

npx React-Native init

Installing packages:

npx install
npx i
npx i @

Uninstalling packages:

npx install

Link packages to android and ios modules:

For all the packages - React-Native link
For a specific package - React-Native link

Unlink packages:

For all the packages - React-Native unlink
For a specific package - React-Native unlink

Start the node packager:

npx React-Native start

Run the project on android device or emulator:

npx React-Native run-android

Run the project on apple device or simulator:

npx React-Native run-ios
npx React-Native run-ios –device
Note: --device only works with apple devices

To create the main JavaScript bundle:

npx React-Native bundle
npx React-Native bundle –platform

Compatibility

Let’s check the compatibility table of @React-Native-community-cli and React Native versions. New CLI’s release cycle is independent of React-Native.

@React-Native-community/cli	React-Native
^5.0.0 (next)	master
^4.0.0 (master)	^0.62.0
^3.0.0	^0.61.0
^2.0.0	^0.60.0
^1.0.0	^0.59.0

To determine which CLI is more effective to develop a React-Native app, take a look at the comparison flow below.

While learning a React Native project, the developer needs to bear in mind that the React Native CLI and Expo CLI are different. The developer should be sure to take a firm decision before designing and implementing React-Native project, without which it is cumbersome to convert the project into another CLI.

How to Create a React Native NPM Package?

meta_prasad — Tue, 23 Mar 2021 10:34:14 +0000

NPM is a Package Manager for Node JS. It was first created in 2009 as an open-source project to help JavaScript developers to easily share their code in the form of packages. NPM allows you to install the various public packages for the project. NPM has over 8,00,000 packages with public access.

My intention behind writing this blog is to help React-native developers create their own package. If any developer wants to share his own package on the NPM registry, then he needs to make it public. This allows developers to contribute to the NPM ecosystem. Steps to create and publish a react-native NPM package are as follows:

There are 3 phases to create and publish a package.

1. Creating the NPM package.
2. Testing the NPM package on the react-native app.
3. Publishing on the NPM website.

1. Creating the NPM package:

First create a folder where package information like package.json, .babelrc, webpack.config.js, etc will be stored. We will introduce these files soon.

Now navigate into that folder directory using terminal and run command – npm init

You will be prompted for the package name, version, main, keyword, etc. You can skip questions (by pressing enter) (it is easy to modify later). At this point, a package.json file will be created.

Now, open the package.json file in your IDE (code editor) and install all the dependencies as below using – npm install dependency-name.

Below is an example of package.json file.

Note: “main” should be the same as above.

Now create a file .babelrc and add the following lines. Babel is a compiler to convert JavaScript code into ES5 JavaScript.

Let’s create a file named webpack.config.js and add the lines below.
Remember, webpack is the builder. It compresses code into ‘build’ that can be deployed in the React-Native app. Make sure “entry” is either ./src/index.js or ./index.js depending upon your file structure.

Now, create a folder src, add the index.js file and add your component.

Whenever you make any change to your package, you have to create the build again using command – npm run build. After that, you must re-install it in the react-native app.

Once you configure the above steps, your folder structure should look as follows

2. Testing the package on React-Native app:

To test or use your package, you will need a React-Native app. Create a React-Native app by executing the run command npm create-react-app “your app name” and open it in your IDE.

You can install your package in two ways

1. Upload it on the NPM website and then install it using npm i “package name”.
2. Locally install it through a relative path of NPM package to react-native app npm i ../react-test-library

Note: We will try to avoid the first option because whenever there is any change in your NPM package, you have to re-publish it on the NPM website and re-install it on your project.

So we will test it locally first and then upload it on the NPM website.

To check your package, you have to install it through the relative path as shown in the above example and import your component from your package.

src/App.js

To see the result of the installed package, run the command in your react-native app – npm start.

Now, let’s see the final step.

3. Publishing on the NPM website:

For publishing any package, you should have an account on the NPM website (if not you can create one). While uploading the same package, the package version should be unique each time.

Steps to upload your package –

1. Using the terminal, navigate to your package directory.
2. Run command – npm login. Enter a username, password, and email id.
3. Run command – npm publish.

Once your package has been published, you can check it on the NPM website.

At last, you are able to create your own library. In case of any queries feel free to share your feedback in the comments section below.

Happy Coding…

React Native vs Native apps development

meta_prasad — Thu, 16 Apr 2020 07:00:06 +0000

React Native has some exciting features that make it popular in the developer community. Many popular apps such as Instagram, Facebook Ads Manager, Walmart, SoundCloud and Netflix are based on React Native. We have worked with both Native app development and React Native, and in this article we share our experience and give some examples. First, a few words regarding the advantages and disadvantages of each.

Native App

A Native application is a software programme developed for a particular operating system. This application can be developed using Java or Kotlin for Android and Objective-C or Swift for iOS and C# for Windows.

High performance – Native apps run much faster than hybrid apps because they are fully supported by the OS on the device.
Better UX/UI – User experience is much better because the higher performance allows everything to run smoothly. Depending on the business need, you can develop device-specific features directly within a Native app.
Interactive – Native mobile apps run more smoothly in comparison to hybrid apps. The interaction with the user is intuitive and natural as they have specific UI standards for each platform.

The major disadvantage of Native apps, is that they work only for one OS, leading to extra development time, and cost in building apps for multiple platforms.

React Native

React Native is an open-source JavaScript framework for building iOS and Android apps. It is famous for its lightweight framework for mobile app development.

Faster development across multiple platforms – React Native allows sharing of the entire codebase between operating systems (Android and iOS). Once you develop an application for Android, you can compile it on iOS and vice versa. This results in a significant saving in the development effort as compared to developing natively on both Android and iOS platforms.
It gives a Native app feel – With React Native, most of the features can be developed as a Native feature. This means that the user experience is the same as a Native app, despite the fact that hybrid technology has been used.
Large Community of Developers – React Native is a popular open-source JavaScript framework, with a well developed community. This means that queries are generally answered quickly on websites such as StackOverflow and GitHub. Furthermore, many helpful libraries created by other developers are freely available for download.
Easy and Live Reloading – When using React Native, code changes are immediately reflected on the simulator and can be tested instantly. By eliminating the need to recompile after every change, a lot of development time is saved.
Cost reduction and Code reuse – With React Native technology, more than 80% of the code can be reused between the Android and iOS platforms, saving a huge amount of development time and cost.

We found that React Native is a superior method that results in major time saving for mobile app development for multiple platforms. Two examples from our experience with React Native are:

App with SQLLite for multiple platforms
App with Bluetooth connectivity feature for multiple platforms

The reason we opted for React Native for these apps, is that in both cases the same business logic layer was required to create two Native apps. Our team successfully built a common business logic layer and UI for both the platforms. We saved significant time and cost due to the reusability of the code. Future maintenance will also be cost-effective. Furthermore, we found that Bluetooth and SQLLite features work efficiently in React Native even though they are not Native based.
