angularjs - Angular js Passport example is not working -

i trying follow example:

i copied , pasted app , server same.

routes work (in server side , client side too)

when tried log in or sign 404 error server.

here server-side routes part.

i checked app.get('/robots.txt') works.

and routes part login (that gave me 404 error):

app.post('/auth/session', session.login);

but tried:

app.post('/auth/session', function(req,res){     console.log('here session requested');     res.sendfile('robots.txt'); });

this code checking whether server respond well.

but still got 404 error.

how can fix works? ir how can test post routings console.log or, else?
