Node.js and SuperTokens: Adding Authentication to Your AP
Last updated March 1, 2024
Introduction
In the modern web development landscape, securing your API is crucial. SuperTokens offers a comprehensive authentication solution that can be seamlessly integrated into Node.js APIs, providing secure session management, user authentication, and more. This guide will walk you through the process of adding SuperTokens authentication to your Node.js API, step by step.
Prerequisites
Before you begin, make sure you have:
- A Node.js environment set up.
- Basic knowledge of creating APIs with Node.js.
- SuperTokens Core installed and running as outlined in the "Installing SuperTokens: A Step-by-Step Guide."
Step-by-Step Integration
- Install SuperTokens Node.js SDK
Start by adding the SuperTokens Node.js SDK to your project. Use npm or yarn to install the package:
bashCopy code
npm install supertokens-node
or bashCopy codeyarn add supertokens-node
- Configure SuperTokens
After installing the SDK, configure SuperTokens in your Node.js application. This involves setting up the SDK to communicate with the SuperTokens Core service and defining your app information.
javascriptCopy code
constSuperTokens = require("supertokens-node"); const { middleware } = require("supertokens-node/framework/express"); const express = require("express"); const app = express(); SuperTokens.init({ framework: "express", supertokens: { connectionURI: "http://localhost:3567", }, appInfo: { appName: "Your App", apiDomain: "http://localhost:3000", websiteDomain: "http://localhost:3000", }, recipeList: [ // Initialize your chosen recipes here ] }); app.use(middleware());
- Add Authentication Routes
SuperTokens simplifies the addition of authentication routes to your API. Utilize the SDK to create endpoints for user registration, login, and logout functionalities.
javascriptCopy code
// Example route for user registration app.post("/auth/signup", async (req, res) => { // Your signup logic here }); // Example route for user login app.post("/auth/login", async (req, res) => { // Your login logic here }); // Example route for user logout app.post("/auth/logout", async (req, res) => { // Your logout logic here });
- Secure API Endpoints
Protect your API endpoints using SuperTokens' session verification. This ensures that only authenticated users can access certain parts of your API.
javascriptCopy code
const { verifySession } = require("supertokens-node/recipe/session/framework/express"); app.get("/protected", verifySession(), (req, res) => { res.json({ message: "This is a protected route." }); });
- Run Your API
With SuperTokens configured and your authentication routes in place, start your Node.js API and test the authentication flow.
bashCopy code
node app.js
- Testing
- Ensure that the signup and login endpoints create new users and authenticate them correctly.
- Verify that protected routes are accessible only when the user is authenticated and that the logout functionality works as expected.
Conclusion
Integrating SuperTokens with your Node.js API adds a layer of security and user management with minimal hassle. By following the steps outlined in this guide, you can implement a robust authentication system, allowing you to focus on developing the core functionalities of your API.
