Node and Auth0 - Integration

 so now we have completed all the steps for integration 

since we have the node and auth0 as two separate things

the integration happens in the app.js 

we need to modify the app.js with some auth0 code 

app.js /

const http = require('http');
const express = require('express');

var router = require('express').Router();
const { auth } = require('express-openid-connect');
const app = express();
app.use('/', router);


const hostname = '127.0.0.1';
const port = 3000;

http.createServer(app)
  .listen(port, () => {
    console.log(`Listening on `);
  });



const config = {
  authRequired: false,
  auth0Logout: true,
  secret: 'a long, randomly-generated string stored in env',
  baseURL: 'http://localhost:3000',
  clientID: 'QxpAXsXkzy0Vm2VdT6dFFS0VOKdrah67',
  issuerBaseURL: 'https://dev-bnga041p.us.auth0.com'
};
console.log(config)

// auth router attaches /login, /logout, and /callback routes to the baseURL
app.use(auth(config));

// req.isAuthenticated is provided from the auth router
app.get('/', (req, res) => {
console.log('entering au')
  res.send(req.oidc.isAuthenticated() ? 'Logged in your App' : 'Logged out from App');
});

//add this to validate routes for authentication it used the same express-openid-connect as ///above for auth
const { requiresAuth } = require('express-openid-connect');

app.get('/profile', requiresAuth(), (req, res) => {

  res.send(JSON.stringify(req.oidc.user));
});



two things to add

var router = require('express').Router();
const { auth } = require('express-openid-connect');
 

the express openid is used for authentication 

so we need to install ' express-openid-connect ' in node to add the dependency

alright now once the code is added restart node app 

now u can see the app behaviour as

when u use the URL - 

http://localhost:3000/login

 a new login page for authentication will be popped up 

enter ur username and password if u don't have one

u can signup using the same screen

the authentication will be done through auth0 and u will land onto page

Logged in your App  is from the code once it is authenticated which u can see from the code 

to verify some user details 

use the URL - http://localhost:3000/profile

 

 to logout from use http://localhost:3000/logout

 so now if you again try to login u will land in the auth page for credentials

a quick look on the code

const config = {
  authRequired: false,
  auth0Logout: true,
  secret: 'a long, randomly-generated string stored in env',
  baseURL: 'http://localhost:3000',
  clientID: 'QxpAXsXkzy0Vm2VdT6dFFS0VOKdrah67',
  issuerBaseURL: 'https://dev-bnga041p.us.auth0.com'
};

 

u can see the clientid is the one from our auth signup  

alright then u can get the code frm the git too 

see u for now .
