You don’t specify what to do on specific routes. You only use `./public` as static folder and set `ejs` as view engine. And that is working. Try going to `/assets/logo.png` (a file in your static folder) or to `/todo` (a view). ---

You only have this `get` route: `app.get('/todo', function(req, res)`. So only when you go to `/todo` your express server will actually do something. If you want to always render the todo view you can use: `app.get('*', function(req, res)` Or if you only want `/` and `/todo` to render the todo view, you can add this route: ```auto app.get('/', function(req, res){ res.redirect('/todo'); }); ``` ---
