How to authenticate firebase with GitHub in ReactJS ?

Last Updated : 26 Jul, 2024

The following approach covers how to authenticate firebase with GitHub in react. We have used the firebase module to achieve so.

Creating React Application And Installing Module:

Step 1: Create a React app using the following command:

npx create-react-app gfgapp

Step 2: After creating your project folder i.e. gfgapp, move to it using the following command:

cd gfgapp

Project structure: Our project structure will look like this.

Step 3: After creating the ReactJS application, Install the firebase module using the following command:

npm install [email protected] --save

Step 4: Go to your firebase dashboard and create a new project and copy your credentials.

const firebaseConfig = {
      apiKey: "your api key",
      authDomain: "your credentials",
      projectId: "your credentials",
      storageBucket: "your credentials",
      messagingSenderId: "your credentials",
      appId: "your credentials"
};

Step 5: Initialize the Firebase into your project by creating Firebase.js file with the following code.

Firebase.js

import firebase from 'firebase';  const firebaseConfig = {     // Your Credentials   };  firebase.initializeApp(firebaseConfig);  var auth = firebase.auth(); var provider = new firebase.auth.GithubAuthProvider(); export {auth , provider};

Step 6: Register your app as a developer application on GitHub and get your app's OAuth 2.0 Client ID and Client Secret.

For Authorization callback URL go to your authentication section and click on Github sign-in method. After that copy the callback URL.

Step 7: Now Enable the Github sign-in method by entering your Client ID and Client Secret.

Step 8: Now install the npm package i.e. react-firebase-hooks using the following command.

npm i react-firebase-hooks

This package helps us to listen to the current state of the user.

Step 9: Create two files i.e. login.js and main.js with the following code.

import {auth , provider} from './firebase'; const Login = ()=>{      // SignIn with GitHub     const submit = ()=>{         auth.signInWithPopup(provider).catch(alert);     }     return (         <div>             <center>             <button onClick={submit}>                 SignIn with Github             </button>             </center>         </div>     ) } export default Login;

main.js

import {auth} from './firebase'; const Main = ()=>{     const logout = ()=>{         auth.signOut();     }     return(         <div>             Welcome              &nbsp;&nbsp;              {                 auth.currentUser.email             }             &nbsp;&nbsp;              <button onClick={logout}>                 Logout             </button>           </div>     ) } export default Main;

Step 10: Finally Import all required files in App.js file as shown below.

App.js

import './App.css'; import Login from './login'; import {auth} from './firebase'; import Main from './main'; import {useAuthState} from 'react-firebase-hooks/auth'; function App() {   const [user] = useAuthState(auth);   return (     user ? <Main/> : <Login/>   ); }  export default App;
