Passport: Unknown authentication strategy “local”

Question

I\'m new to NodeJS and I try to build a login/registration system. Registration works fine but I\'m currently unable to login.

I find a example app using passport and no

Answer 1

this fix the error. need to use 'local' when you create a new LocalStrategy

passport.use('local', new LocalStrategy({
    usernameField:'useName',
    passwordField: 'password',
    passReqToCallback: true

Answer 2

You forgot to import passport config file in your app.js.

import passport config after initializing passport.

app.use(passport.initialize());
app.use(passport.session());
// Add the line below, which you're missing:
require('./path/to/passport/config/file')(passport);

Hope this helps.

i have done like this and it worked

$npm install passport-local

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy; /* this should be after passport*/



 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, { message: 'Incorrect username.' });
      }
      if (!user.validPassword(password)) {
        return done(null, false, { message: 'Incorrect password.' });
      }
      return done(null, user);
    });
  }
));
