How to Login with Google API & store user data in MongoDB using Nodejs , expressJS , MongoDB

// Create a File passport.js 


Before creating passport.js  we must have client id , and client secret- . Get your clientID & Client Secret from Google Developer Account using link https://console.cloud.google.com/apis/credentials/consent?project=vernal-zone-374906  

// Make Oauth constent - UserType - External 



== set/add scope email & profile 




Then in Credential setting create new credentials to get Client Id and Client Secret 



//passport.js

import passport from 'passport';

import GoogleStrategy from 'passport-google-oauth2'

import {Strategy} from 'passport-google-oauth2'

passport.serializeUser((user , done) => {

done(null , user);

})

passport.deserializeUser(function(user, done) {

done(null, user);

});


passport.use(new GoogleStrategy({

clientID:"43989350384-ckjvij697vt7g3kdpg9dqe16k60k248.apps.googleusercontent.com",

clientSecret:"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e", // Your Credentials here.

callbackURL:"http://localhost:3000/auth/callback",

passReqToCallback:true

},

function(request, accessToken, refreshToken, profile, done) {

return done(null, profile);

}

));

For example if your friend name is kilvish , if you want to create a branch named kilvish , you would run: make sure you would be on main branch already   command->  git checkout -b kilvish git push origin kilvish 2. Set Up Your Friend’s Environment( On your Friend's System )  at kilvish side  run ->  Clone the Repository (if not already done): If your friend hasn’t cloned the repository yet, they should do so: command ->  git clone https://github.com/Vasu-Birla/your-repo.git   // your your main clone line  Fetch All Bran...
