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 firebase@8.3.1 --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.Â
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.
login.js
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                             {                 auth.currentUser.email             }                             <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() { Â Â const [user] = useAuthState(auth); Â Â return ( Â Â Â Â user ? <Main/> : <Login/> Â Â ); } Â Â export default App; |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
