A Google oAUth Sign-in / Log-in Component for React
npm install react-google-login
import React from 'react';
import ReactDOM from 'react-dom';
import GoogleLogin from 'react-google-login';
const responseGoogle = (response) => {
console.log(response);
}
ReactDOM.render(
<GoogleLogin
clientId="658977310896-knrl3gka66fldh83dao2rhgbblmd4un9.apps.googleusercontent.com"
buttonText="Login"
onSuccess={responseGoogle}
onFailure={responseGoogle}
/>,
document.getElementById('googleButton')
);
If offline is false callback will return the GoogleAuth object.
If offline is true callback will return the offline token for use on your server.
If you use the hostedDomain param, make sure to validate the id_token (a JSON web token) returned by Google on your backend server:
- In the
responseGoogle(response) {...}
callback function, you should get back a standard JWT located atresponse.hg.id_token
- Send this token to your server (preferably as an
Authorization
header) - Have your server decode the id_token by using a common JWT library such as jwt-simple or by sending a GET request to
https://www.googleapis.com/oauth2/v3/tokeninfo?id_token=YOUR_TOKEN_HERE
- The returned decoded token should have an
hd
key equal to the hosted domain you'd like to restrict to.
