Austin SDK for Node.js

Hey there! Welcome to the Austin SDK authentication helper. This little library makes it super easy to connect your Node.js apps with our awesome auth system.

What's this all about?

If you're building an app that needs to authenticate users through auth, this SDK handles all the OAuth for you.

Getting Started

First, grab the package:

npm install @austinsdk/auth

Then you're ready to go:

const Auth = require('@austinsdk/auth');

// Set up your auth client with your app's credentials
const auth = new Auth(
    'https://auth.austinsdk.me',        // The auth server URL
    'your-client-id',                   // Your app's client ID
    'your-client-secret',               // Your app's client secret (keep this safe!)
    'https://yourapp.com/callback'      // Where users get sent after auth
);

How to use it

Step 1: Send users to login

When someone wants to log into your app, redirect them to the auth URL:

// This creates a URL that sends users to Austin's login page
const authUrl = auth.getAuthUrl();

// Optional: use a different redirect URL for this specific request
const customAuthUrl = auth.getAuthUrl('https://yourapp.com/special-callback');

console.log('Send your user here:', authUrl);

Step 2: Exchange the code for a token

After users log in, they'll be redirected back to your app with a special code. Trade that code for an access token:

// Assuming you got the code from the URL parameter
const code = 'the-code-from-the-redirect';

try {
    const tokenResponse = await auth.codeForToken(code);
    console.log('Got a token!', tokenResponse.access_token);
} catch (error) {
    console.log('Oops, something went wrong:', error);
}

Step 3: Do cool stuff with the token

Now you can get user info and their projects:

const token = tokenResponse.access_token;

// Get info about the logged-in user
const userInfo = await auth.getUserInfo(token);
console.log('Hello,', userInfo.name || userInfo.username);

// Get their projects
const projects = await auth.getProjects(token);
console.log(`You have ${projects.length} projects!`);

// Check if the token is still valid
const verification = await auth.verify(token);
if (verification.valid) {
    console.log('Token looks good!');
} else {
    console.log('Time to refresh that token...');
}
