Usage

Configure Strategy

The local authentication strategy authenticates users using a username and password. The strategy requires a verify callback, which accepts these credentials and calls done providing a user.

const passport = require('passport-koa2);
const LocalStrategy = require('passport-local').Strategy;

passport.use(new LocalStrategy(
  function(username, password, done) {
    User.findOne({ username: username }, function (err, user) {
      if (err) { return done(err); }
      if (!user) { return done(null, false); }
      if (!user.verifyPassword(password)) { return done(null, false); }
      return done(null, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'local' strategy, to authenticate requests. It searches for fields in the query string and ctx.body, so ensure body parsers are in place if these fields are sent in the body.

For example, as route middleware in an Koa application:

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

Callback:

app.post('/login', passport.authenticate('local', (err, result, ctx) => {
 //
}));
