Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Easy-auth

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.

Installation

You can install this package via npm:

npm install Easy-auth

Import

import this package to make your node auth easy

const { Register, verifyOtp, Login, tokenVerification, Logout } = require('easy-auth');

Usage

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 } = require('easy-auth');

const app = express();

app.use(cookieParser());
app.use(express.json());

// Connect to MongoDB
const dbtoken = 'mongodb://localhost:27017/testdb';
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}`);
});

Registering a New User

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' });
    });
});

Verifying OTP

Verify OTP (one-time password) for user authentication with a POST request to /verify-otp:


app.post('/verify-otp', (req, res) => {
  verifyOtp(req, res);
  res.json({ message: 'OTP verified' });
});

User Login

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' });
    });
});

Protected Routes with Token Verification

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 });
});

User Logout

Log out a user by sending a GET request to /logout:

app.get('/logout', Logout, (req, res) => {
  res.json({ message: 'User logged out successfully' });
});
