Express.js res.render dot name file

Question

How can I use dot named file on res.render() in express.js? For instance,

There is template file named view.sample.ejs , I want to render it

app.get('/sample', function(req, res){
    res.render('view.sample');
})

The result is,

Error: Cannot find module 'sample'

How can I use dots?

(plus)

I want to name follow mvc model, like

sample.model.js
sample.controller.js
sample.view.ejs
sample.view.update.ejs ...

No problem js file, but render ejs file I couldn't.

If we look at the library node_modules/express/lib/view.js, we find that the design of the path to the template everything after the dot in the file name shall be considered as an extension:

this.ext = extname(name); // 'view.sample' => '.sample'
this.name = name;         // 'view.sample' => 'view.sample'

And when we try to load the corresponding file extension engine will generate an error:

if (!opts.engines[this.ext]) { // '.sample' engine not found
  // try load engine and throw error
  opts.engines[this.ext] = require(this.ext.substr(1)).__express;
}

Ok, what to do? Just add the extension:

app.get('/sample', function(req, res){
  res.render('view.sample.ejs');
})
