Introduction to Sidebase Nuxt-Auth

Sidebase Nuxt-Auth is a powerful authentication module tailored for Nuxt3 applications. It facilitates the integration of diverse authentication methods, making your application secure and accessible.
Here you can find the documentation thanks to @danielroe and all other devs that maintain and contribute to the project

Getting Your Project Ready

Before diving into the authentication setup, make sure you have a Nuxt3 application up and running. If you're just starting, here's how to create a new Nuxt3 project:

npx nuxi init nuxt3-app
cd nuxt3-app
npm install
Enter fullscreen mode Exit fullscreen mode

Next, add the necessary authentication packages to your project:

npm install @next-auth/prisma-adapter next-auth @prisma/client bcrypt
Enter fullscreen mode Exit fullscreen mode

Configuring Sidebase Nuxt-Auth

The core of setting up Sidebase Nuxt-Auth lies in its configuration.

Let's break it down:

Step 1: Authentication Handler Setup

Initialize the NuxtAuthHandler with your secret and session strategy:

import { NuxtAuthHandler } from '#auth'

export default NuxtAuthHandler({
  secret: 'A_Strong_Secret',
  session: { strategy: 'jwt' },
Enter fullscreen mode Exit fullscreen mode

Step 2: Adding Authentication Providers

Sidebase Nuxt-Auth supports various providers. Here's how to add some common ones:

Email Provider:

  server: process.env.EMAIL_SERVER,
  from: process.env.EMAIL_FROM,
Enter fullscreen mode Exit fullscreen mode

Social Providers (e.g., GitHub, Google):

  clientId: process.env.GITHUB_CLIENT_ID,
  clientSecret: process.env.GITHUB_CLIENT_SECRET,
Enter fullscreen mode Exit fullscreen mode

Step 3: Customizing Authentication Pages and Callbacks

Specify custom routes for authentication actions in your configuration:

pages: {
  signIn: '/auth/login',
  signOut: '/auth/logout',

Enter fullscreen mode Exit fullscreen mode

Use callbacks for additional control over the authentication flow:

callbacks: {
  async signIn({ user }) {
    // Custom logic here
    return true;
Enter fullscreen mode Exit fullscreen mode

Securely Storing Secrets

Remember to use environment variables for storing sensitive information like client secrets, avoiding hard-coded values in your source code.

Implementing User Registration
A crucial part of managing user authentication is allowing users to register. Here's a basic overview:

Define an Event Handler:

Start by creating an event handler that processes registration requests:

import { hash } from 'bcrypt';

export default defineEventHandler(async (event) => {
  // Registration logic here
Enter fullscreen mode Exit fullscreen mode

Read and Validate User Input:

Ensure the provided information is valid and the user doesn't already exist:

const body = await readBody(event);
const userExists = /* logic to check if user exists */;
if (userExists) {
  // Handle existing user case
Enter fullscreen mode Exit fullscreen mode

Store User Credentials Securely:

Hash the user's password and store the new user in the database:

const hashedPassword = await hash(body.password, 10);
// Logic to create user record
Enter fullscreen mode Exit fullscreen mode

Final Thoughts

Integrating Sidebase Nuxt-Auth enhances your Nuxt3 project's security and user experience by offering a streamlined authentication system. By following the steps outlined, you can set up a versatile authentication system that caters to a wide range of use cases.

Remember, the effectiveness of your authentication system not only lies in its setup but also in regular maintenance and adherence to security best practices.
