What is koa-passport?

koa-passport is a Koa middleware that integrates Passport.js for authentication. It allows you to use various authentication strategies, manage user sessions, and protect routes in a Koa application.

What are koa-passport's main functionalities?

Authentication Strategy

This code demonstrates how to set up a local authentication strategy using koa-passport. It includes initializing the Koa app, setting up the LocalStrategy, and defining a login route.

const Koa = require('koa');
const Router = require('koa-router');
const bodyParser = require('koa-bodyparser');
const passport = require('koa-passport');
const LocalStrategy = require('passport-local').Strategy;

const app = new Koa();
const router = new Router();

passport.use(new LocalStrategy((username, password, done) => {
  // Replace with your own logic
  if (username === 'user' && password === 'pass') {
    return done(null, { id: 1, username: 'user' });
  } else {
    return done(null, false);
  }
}));

app.use(bodyParser());
app.use(passport.initialize());
app.use(passport.session());

router.post('/login', passport.authenticate('local', {
  successRedirect: '/success',
  failureRedirect: '/login'
}));

app.use(router.routes());
app.listen(3000);

Session Management

This code demonstrates how to set up session management with koa-passport. It includes initializing session middleware and defining serializeUser and deserializeUser functions.

const session = require('koa-session');

app.keys = ['your-session-secret'];
app.use(session({}, app));

passport.serializeUser((user, done) => {
  done(null, user.id);
});

passport.deserializeUser((id, done) => {
  // Replace with your own logic
  done(null, { id: 1, username: 'user' });
});

Protecting Routes

This code demonstrates how to protect routes using koa-passport. It includes defining a protected route that requires authentication.

router.get('/protected', passport.authenticate('local', { session: false }), (ctx) => {
  ctx.body = 'This is a protected route';
});
