This npm package provides functionalities for user registration, OTP verification, user login, token verification, and user logout using Express.js and Mongoose for MongoDB integration.
We have taken care of installing the following peer dependencies. Just install node-easy-auth and you are good to go.
npm install node-easy-authcookie-parserexpressjsonwebtokenmongoosenodemailer
import this package to make your node auth easy
const { Register, VerifyOtp ,Login,TokenVerification,Logout,ResendOtp} = require('node-easy-auth');Setting Up Express Server First, import necessary modules and set up your Express server:
const express = require('express');
const mongoose = require('mongoose');
const cookieParser = require('cookie-parser');
const { Register, VerifyOtp, Login, TokenVerification, Logout, ResendOtp } = require('node-easy-auth');
const app = express();
app.use(cookieParser());
app.use(express.json());
// Connect to MongoDB
const dbtoken = process.env.MONGODBURL;
mongoose.connect(dbtoken).then(() => {
console.log('MongoDB connected');
}).catch((err) => {
console.error('MongoDB connection error:', err);
});
// Start the server
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
Use the /register endpoint with a POST request to register a new user:
app.post('/register', (req, res) => {
Register(req, res)
.then((user) => {
res.json({ message: 'User registered successfully', user });
})
.catch((err) => {
console.error('Registration error:', err);
res.status(500).json({ error: 'Registration failed' });
});
});{
"username":"xyz",
"email":"[email protected]",
"password":"xyz@123"
}Verify OTP (one-time password) for user authentication with a POST request to /verify-otp:
app.post('/verify-otp',(req,res)=>{
VerifyOtp(req,res).then((e)=>{
res.json({otp:e})
}).catch((err)=>{
res.json({otp:err})
})
}){
"otp":"2443",
}Verify OTP (one-time password) for user authentication with a POST request to /verify-otp:
app.get('/resendotp', (req, res) => {
ResendOtp(req,res).then(()=>{
res.json({ status:true,msg: 'otp sent' });
}).catch((err)=>{
res.json({ status:true,msg: `otp sent${err}` });
})
});Authenticate a user by sending a POST request to /login:
app.post('/login', (req, res) => {
Login(req, res)
.then((user) => {
res.json({ message: 'Login successful', user });
})
.catch((err) => {
console.error('Login error:', err);
res.status(401).json({ error: 'Login failed' });
});
});{
"email":"[email protected]",
"password":"xyz@123"
}Access protected routes by sending a GET request to /protected-route. This route requires token verification using the tokenVerification middleware:
app.get('/protected-route', TokenVerification, (req, res) => {
// Access user data from decoded token in req.user
res.json({ message: 'Protected route accessed successfully', user: req.user });
});Log out a user by sending a GET request to /logout:
app.get('/logout', Logout, (req, res) => {
res.json({ message: 'User logged out successfully' });
});Add these variable in your environment file
