Usage

Zerouth is designed to make OAuth authentication easier in your Node.js applications. Below is an example of how to use Zerouth to handle OAuth authentication with different platforms.

const passport = require('passport');
const zerouth = require('0uth'); // Replace with the correct import path
const express = require("express");

const app = express();

//use middlwares in this sequence only
app.use(require("express-session")({ secret: 'SECRET' , resave: true, saveUninitialized: true}))
app.use(passport.initialize())
app.use(passport.session())

// Define your OAuth configuration
const GoogleConfig = {
  client: 'google',
  client_id: 'GOOGLE_CLIENT_ID',
  redirect_url: '/google/callback', //add http://localhost:3000/google/callback in google cloud console
  client_secret: 'GOOGLE_CLIENT_SECRET',
  success_redirect: '/success',
  failure_redirect: '/login',
  scope: ["email", "profile"]
};

const LocalStrategy = {
  client: 'local',
  client_id: null, //<could_use_cookie>
  client_secret: null, //<could_use_cookie>
  redirect_url: '/local/callback',
  success_redirect: '/local/lmao',
  failure_redirect: '/login',
  //cb takes (3 argumensts, [req, res, callback])
  cb: (req, res, callback)=>{
    // if(cookie) return ValidateCookie(cookie, (result:String)=>{callback(null, {username: result.username)})

    // validate username and password using your own database
    if(req.body.username == "admin" && req.body.password == "admin"){
      return callback(null, {username: req.body.username, password: req.body.password})
    }
    
  }
}

// Apply the zerouth to your Express app
app.use(
  zerouth("/auth/google", GoogleConfig)
);

app.use(
  zerouth("/auth/local", LocalStrategy)
);

// Handle successful authentication
app.get('/success', (req, res) => {
  return res.send(req.user);
});

// Start your Express server
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Configuration Options

client: The name of the OAuth client (e.g., 'google', 'discord').
client_id: The client ID provided by the OAuth provider.
client_secret: The client secret provided by the OAuth provider.
redirect_url: The callback URL to redirect to after successful authentication.
success_redirect: The URL to redirect to after successful authentication.
failure_redirect: The URL to redirect to after failed authentication.
scope: (Optional) An array of scope strings for requesting specific permissions.
...other configuration options specific to each OAuth provider.

Error Handling

Zerouth provides detailed error handling for various scenarios, including invalid configuration, unsupported clients, and duplicate paths or URLs. Make sure to handle errors appropriately based on your application's requirements.
