Auth Service Package

An Auth service built using Node.js, TypeScript, PostgreSQL, Passport.js (Google Strategy and LocalStrategy), JWT for token management.

Features

• Google OAuth2 Authentication: Securely authenticate users via their Google accounts.- Generate JWT tokens for authenticated users for secure API access.
• Store user data and authentication details securely.
• Utilize TypeScript for type safety and better code maintainability.
• Write unit and integration tests to ensure code reliability.

Installation

1. Install

npm install is-auth-service

Usage

1. Setup

• app.js

import { AUTH_ROUTES, setAuthConfig, passportInit } from 'is-auth-service';
import express from 'express';

const app = express();

app.use(
  session({
    secret: 'YOUR_SESSION_SECRET',
    resave: false,
    saveUninitialized: true,
    cookie: { secure: false },
  })
);

// google passport
passportInit({ app, googleConfig: {
  googleClientId: 'YOUR_GOOGLE_CLIENT_ID',
  googleSecret: 'YOUR_GOOGLE_SECRET',
  callbackUrl: 'https://CLIENT_URL',
}});

// or local stategy
passportInit({ app });

// Register routers
app.use((req: any, res, next) => {
  req.jwtSecret = jwtSecret;
  req.redirectUrl = process.env.CLIENT_URL ?? 'http://localhost:3000'
  next();
}, authRouter);

2. Use middleware in router

• protected router

import express from 'express';
import { authenticateJWT } from 'is-auth-service';
import { addFunction } from './controllers/YOUR_ROUTER';

const router = express.Router();

router.post(
  '/',
  (req, res, next) => {
    req.jwtSecret = 'jwtSecret';
    next();
  },
  authenticateJWT,
  addFunction
);

• Auth Routers

// app.js
import express from 'express';
import { authRouter } from 'is-auth-service';

const app = express();

app.use(authRouter);

3. Access to the routes

• Google login: GET https://YOUR_SERVER_URL/google
• Local login: GET https://YOUR_SERVER_URL/local/login
• Generate jwt: POST https://YOUR_SERVER_URL/generate-token
• Get User: GET https://YOUR_SERVER_URL/user/:id
