We need to create two middleware to handle 404 and 500 errors. You could make it work somehow, but it would a dirty hack job, we need to use the right approach, so abandon this method. Because the router middleware is added before the static middleware, it will intercept the requests for static file like CSS, JavaScript etc. This approach is wrong, it is using a route to handle 404 error. You may come across some suggestions like the following to handle 404 errors: app.get('*', function(req, res). In the third line, we are setting up our static directory for serving CSS, JavaScript, images etc. In the second line, we are adding Stylus to pre-process our CSS files. In the first line, we have added the router middleware, which makes defining routes in Express possible. Īpp.use(require('stylus').middleware(_dirname + '/public')) Īpp.use(express.static(path.join(_dirname, 'public'))) To get some context, open app.js and find these lines. I will also assume that you created the skeleton of your app using the express command (if you did not, start using it - type express -h at the command line). If you are asking this question, I will assume that you already have a working Express application and you are familiar with the application code, at least somewhat.
