Express.js routing with default route

Question

I have the following Express.js code:

router = express.Router()
fs.readdirSync('./controllers').forEach(function (file) {
  if(file.substr(-3) == '.js') {
      route = require('./controllers/' + file);
      route.controller(router);
  }
});
app.use('/', router);

It works good. I don't set path for '/' route in my controllers, and my Express.js server renders 'index.html' from 'public' folder by default - this is what I want. Now I want to add '*' route, so Express.js return 'index.html' from 'public' folder - it's static file, no need to render, just returning. How can i do it? Thanks

Answer 1

If you want your service to serve up public/index.html from your root path you can simply use express.static like this:

app.use(express.static('public'));

express.static will treat index.html as your index file by default, and you can configure this in the 2nd argument:

app.use(express.static('public', {index: 'myIndex.html'}))

Note also that you don't have to specify the root to app.use the way you are. Simply do this:

app.use(router);

I would even suggest that your route.controller() methods are not necessary. If each of your controllers exported their own express.Router() you could simply do app.use(myController) in your iterator.
