As the second parameter, the .init method takes a callback that returns a browsersync object that has an app property, this is connect server , and then themselves ...

browsersync.init
    files:[
      project + '**/*.html'
      cssDir + '**/*.css'
      jsDir + '**/*.js'
    ]
    open: false
    server:
      baseDir: project
    ,(err,bs)->
      if err
        gutil.log err
        return do gutil.beep

      bs.app.use '/post', (req, res, next) ->
        setTimeout (->
          res.end 'Speed: 1'
          return
        ), 1000
      bs.app.use '/post3', (req, res, next) ->
        setTimeout (->
          res.end 'Speed: 3'
          return
        ), 3000
      opn "http://localhost:3000"

return browsersync.init({
    files: [project + '**/*.html', cssDir + '**/*.css', jsDir + '**/*.js'],
    open: false,
    server: {
      baseDir: project
    }
  }, function(err, bs) {
    if (err) {
      gutil.log(err);
      return gutil.beep();
    }
    bs.app.use('/post', function(req, res, next) {
      return setTimeout((function() {
        res.end('Speed: 1');
      }), 1000);
    });
    bs.app.use('/post3', function(req, res, next) {
      return setTimeout((function() {
        res.end('Speed: 3');
      }), 3000);
    });
    return opn("http://localhost:3000");
  });
