[NJS] Server, templates and the pipeline

:  ~ 1 min read

As I said in my previous post, I will do a suite of posts regarding the migration of my website from ruby to Node.js, and to make them easier to spot, I will prefix them with [NJS]. Small warning: I'm not a semicolon user. I've read quite a bit about it, and I made my choice knowingly.

So, the first thing I picked was Express, a really nice web application framework. All it takes to have it running is:

var app = require('express')()

app.get('/', function(req, res) {
  res.render('index', { name: 'Roland' })
app.listen(process.env.PORT || 3000)
app.set('view engine', 'ejs')

ejs is a framework for JS templates, which looks for files in a views folder, at the root of your project. You can combine JS with pure HTML, just like you can combine ruby with it in erb:

<!DOCTYPE html>
  Hello <%= name >!

Next, the assets pipeline: Mincer. I kinda like Sprockets, so this was an obvious choice:

var Mincer = require('mincer')
var pipeline = new Mincer.Environment()


app.use('/assets', Mincer.createServer(pipeline))

Now you can access your assets directly, without remembering how many ../ you need to add to reach it:

<link rel="stylesheet" href="/assets/font-awesome/css/font-awesome.min.css">
<img src="/assets/misc/image.png" alt="Image"/>

Coincidentally enough, Express was inspired by Sinatra, Mincer by Sprockets and ejs is just like erb. Funny thing is that the only one I knowingly picked due to this reason was Mincer.

Next I will write about routes.
