PassportJS in Nodejs never call the callback function

Question

I am trying to authenticate the yammer user using Passport.

It can get through yammer authentication page and I can click to allow access but the function never gets call. ( As you might see in my code, I just want to print all accessToken, profile but it never prints them out. )

Please help me I might not do it properly.

var express = require("express");
var app = express();
var passport = require("passport");
var YammerStrategy = require("passport-yammer").Strategy
passport.use(new YammerStrategy({
  clientID: "",
  clientSecret: "",
  callbackURL: "/"
  },
  function(accessToken, refreshToken, profile, done){
    process.nextTick(function (){
      console.log("strategy");
      console.log(profile);
      console.log(accessToken);
      console.log(refreshToken);
    });

  }
));

app.get('/login', passport.authenticate('yammer'));
app.listen(3000);
console.log('Listening on port 3000');

Answer 1

it happens because you never calling passport done callback, just call it

passport.use(new YammerStrategy({
  clientID: "",
  clientSecret: "",
  callbackURL: "/"
  },
  function(accessToken, refreshToken, profile, done){
    console.log("strategy");
    console.log(profile);
    console.log(accessToken);
    console.log(refreshToken);

    done(null, profile);
  }
));

and because you don't add your passport middleware:

app.configure(function() {
  app.use(express.static('public'));
  app.use(express.cookieParser());
  app.use(express.bodyParser());
  app.use(express.session({ secret: 'keyboard cat' }));
  app.use(passport.initialize());
  app.use(passport.session());
  app.use(app.router);
});
app.get('/login', passport.authenticate('yammer'));
app.listen(3000);
console.log('Listening on port 3000');
