Follow this tutorial to learn how to create a React Native SDK for your native module. See how to use TypeScript, Jest, and Native Modules API

Understanding React Native SDKs

A React Native SDK comprises a collection of reusable components, functions, and utilities bundled together for easy integration into various projects. Creating an SDK involves defining functionalities, exporting components, and ensuring seamless usability for other developers.

Steps To Create a React Native SDK

1. Project Setup

Initiate a new React Native project for the authentication SDK:

npx react-native init AuthSDK

2. Define SDK Components and Features

Identify the core functionalities and components your SDK will offer. Create reusable components and utilities that can be packaged together.

Example: Authentication Component

// AuthComponent.js
import React from 'react';
import { View, TextInput, Button, Alert} from 'react-native';
import axios from 'axios';

export const AuthComponent = ({ onLogin }) => {
  const [username, setUsername] = React.useState('');
  const [password, setPassword] = React.useState('');

  const handleLogin = () => {
     //Username and password are requied to login
    if(!username && password){
        Alert.alert("Validation", "Please enter username and password");
        //API Calling with Axios'Rest_Api_Url', {
            username: username,
            password: password
            .then(function (response) {

                 //Here you can handle the success case
            .catch(function (error) {
                // Error handling

  return (
      <Text>User Login</Text>
      <Button title="Login" onPress={handleLogin} />

3. Export SDK Functionalities

Export the components, functions, or utilities that you want to make accessible to other developers using your SDK.

Example: Exporting SDK Components

// index.js
export * from './AuthComponent';

4. Document the SDK

Create comprehensive documentation detailing how developers can use your SDK. Include usage examples, code snippets, and explanations for each exported functionality.

5. Test the SDK

Perform thorough testing of each functionality within your SDK. Ensure proper behavior, error handling, and compatibility across different React Native versions.

6. Package the SDK

Bundle your SDK into a distributable package using npm or yarn.

npm pack

7. Publish the SDK

Publish the packaged SDK to a package registry like npm or a private repository, making it accessible for other developers to install and use.

Integrating the SDK Into Other Apps

1. Install the SDK in Other React Native Apps

npm install AuthSDK

2. Import and Use SDK Components or Functionalities

import { AuthComponent } from 'AuthSDK';

// Use AuthComponent in your app's authentication flow

3. Utilize SDK Functionalities in Other Apps

Integrate and use the exported components and functions from the SDK within the codebase of other React Native applications.

Best Practices for React Native SDK Development

  • Modularity: Design the SDK to be modular and easily extensible for future updates.
  • Documentation: Provide comprehensive documentation to facilitate easy integration for developers.
  • Versioning: Implement version control to manage changes and ensure backward compatibility.
  • Error Handling: Include robust error-handling mechanisms within the SDK.
