HTMLing
Polymer compatible HTML5 based templating syntax for node.js. Render your templates server-side using the same syntax as in the browser, with no virtual DOM trickery required.
For a full demonstration, please see htmling-demo-app.
Installation
via npm
npm install htmling
Example
Turns this:
<!doctype html>
<html>
<head>
<title>{{title}}</title>
<meta name="description" content="{{description}}">
</head>
<body>
<h1>{{title}}</h1>
<ul>
<template repeat="{{user in users}}">
<li>{{user.name}}</li>
</template>
</ul>
</body>
</html>
plus this:
{
"title": "User List",
"description": "A list of users",
"users": [
{
"name": "Alice"
},
{
"name": "George"
}
]
}
into this:
<!doctype html>
<html>
<head>
<title>User List</title>
<meta name="description" content="A list of users">
</head>
<body>
<h1>User List</h1>
<ul>
<li>Alice</li>
<li>George</li>
</ul>
</body>
</html>
How it works
Unlike similar libraries, HTMLing does not require a virtual DOM such as jsDOM. Instead, HTMLing
parses .html files and transforms them into very efficient executable JavaScript functions.
It uses a parser written in PEG.js which emits a standard Mozilla Parser API AST with some custom node types. The compiler then uses estraverse to convert these custom node types to standard JavaScript expressions. Finally, the result is passed to escodegen which converts the AST into executable JavaScript.
This compilation process happens only once, and the resulting JavaScript is extremely efficient.
Usage
HTMLing is easy to integrate with your existing build process, either via the command line or library interfaces.
CLI
HTMLing ships with a small command line interface:
Compile an individual file
The compiled output will be written to STDOUT
htmling ./file.html
Compile an individual file to a destination
The compiled output will be written to compiled.js.
htmling -o ./compiled.js ./file.html
Compile a directory hierarchy
Compile a nested directory structure to a directory called compiled. The output
directory will be created if it does not already exist, and the resulting folder structure will
match that of the input.
htmling -o ./compiled ./pages
Compile a directory hierarchy to a single file
Compile a nested directory structure to a single called compiled.js
htmling -c -o ./compiled.js ./pages
As a Library
It's also possible to use HTMLing as a library:
Compile a string
var HTMLing = require('htmling');
var template = HTMLing.string('Hello {{name}}');
console.log(template.render({name: 'Charles'})); // "Hello Charles"
Compile a file
var template = HTMLing.file('./index.html');
console.log(template.render());
Compile a directory
var templates = HTMLing.dir('./pages');
console.log(templates.render('index.html', {}))
Using as an express view engine
HTMLing has support for express.js.
var HTMLing = require('htmling');
app.configure(function(){
app.engine('html', HTMLing.express(__dirname + '/views/'));
app.set('view engine', 'html');
});
In development mode, you'll probably want to enable the watch option. This will reload your
templates when they change on disk:
var HTMLing = require('htmling');
app.configure(function(){
app.engine('html', HTMLing.express(__dirname + '/views/', {watch: true}));
app.set('view engine', 'html');
});

Docker environment
All you need is Docker with docker-compose available from your terminal.
We have a fancy shortcut to get your application up and running, and you also get access to the container terminal:
$ make build
$ make run
From this point, it's just a matter of starting the application from within the container shell:
htmling:~/app(master)$ npm test
Other fancy shortcuts we have for Docker fans
$ make into open a new container terminal$ make stopto stop all containers$ make cleanto clean the Docker environment
