Code Examples
Learn how to integrate LittleAuth with practical examples.
Authentication Examples
JavaScript
Basic Authentication Flow
// Initialize LittleAuth
const auth = new LittleAuth({
clientId: 'your-client-id',
redirectUri: 'https://your-app.com/callback'
});
// Start the login flow
function login() {
auth.login('google');
}
// Handle the callback
async function handleCallback() {
try {
const user = await auth.handleCallback();
console.log('User authenticated:', user);
// Store the user info and tokens
localStorage.setItem('user', JSON.stringify(user));
// Redirect to the dashboard
window.location.href = '/dashboard';
} catch (error) {
console.error('Authentication error:', error);
}
}
This example shows how to implement a basic authentication flow using the LittleAuth JavaScript SDK.
Python
Flask Integration
from flask import Flask, redirect, request, session
from littleauth import LittleAuth
app = Flask(__name__)
app.secret_key = 'your-secret-key'
auth = LittleAuth(
client_id='your-client-id',
client_secret='your-client-secret',
redirect_uri='http://localhost:5000/callback'
)
@app.route('/')
def index():
return 'Welcome to LittleAuth Example! Login'
@app.route('/login')
def login():
auth_url = auth.get_authorization_url('google')
session['oauth_state'] = auth.state
return redirect(auth_url)
@app.route('/callback')
def callback():
code = request.args.get('code')
state = request.args.get('state')
if state != session.get('oauth_state'):
return 'State mismatch. Possible CSRF attack.', 400
try:
user = auth.handle_callback(code)
session['user'] = user
return redirect('/dashboard')
except Exception as e:
return f'Error: {str(e)}', 400
@app.route('/dashboard')
def dashboard():
if 'user' not in session:
return redirect('/login')
user = session['user']
return f'Welcome, {user["name"]}! You are logged in with {user["provider"]}.'
if __name__ == '__main__':
app.run(debug=True)
This example demonstrates how to integrate LittleAuth with a Flask application.
