no-build-conf

No build conf - build script

Optimize your SPA programmatically.

This project is greatly inspired by @mklabs works.

Tested on Linux and Windows.

### HTML modification

Add "data-build"="NAME_OF_THE_OPTIMIZED_ASSET" to every assets (css or js) you want to optimize. Here app.css and app.js.

<link rel="stylesheet" href="css/style.css" data-build="app.css">

<!-- scripts concatenated and minified via build script -->
<script src="vendor/log.js" data-build="app.js"></script>
<script src="vendor/underscore.js" data-build="app.js"></script>
<script src="vendor/backbone.js" data-build="app.js"></script>
<script src="vendor/handlebars.runtime-1.0.0.beta.6.js" data-build="app.js"></script>
<script src="application.js" data-build="app.js"></script>
<script src="lib/util.js" data-build="app.js"></script>
<script src="lib/jquery.plugin.js" data-build="app.js"></script>
<script src="lib/Backbone.plugin.js" data-build="app.js"></script>
<script src="model/Todo.js" data-build="app.js"></script>
<script src="template/templates.js" data-build="app.js"></script>
<script src="view/todo/TodoView.js" data-build="app.js"></script>
<script src="Router.js" data-build="app.js"></script>
<!-- end scripts -->

Result

The result is an optimized directory:

The previous HTML portion now look like this:

<link rel="stylesheet" href="app.459703.css" data-build="app.css">
<script src="app.6423e0.js" data-build="app.js"></script>

CSS and JS are:

• minified
• merged
• MD5'd

Install this project

You need nodejs installed.

$ [sudo] npm install -g no-build-conf

Use the build script as a library

The no-build-conf build script works like connect middlewares.

Here processors/middlewares less, optipng, jpegtran, script, link, css-b64-images, html-minifier are applied in order.

var buildScript = require('no-build-conf');

var processors = [
  require('no-build-conf/lib/processors/file/less'),
  require('no-build-conf/lib/processors/file/optipng'),
  require('no-build-conf/lib/processors/file/jpegtran'),
  require('no-build-conf/lib/processors/dom/script'),
  require('no-build-conf/lib/processors/dom/link'),
  require('no-build-conf/lib/processors/dom/css-b64-images'),
  require('no-build-conf/lib/processors/dom/exclude'),
  require('no-build-conf/lib/processors/file/html-minifier')
];

build(target_dir, output_dir, processors, function(err, newFile){
    if(err) throw err;
    console.log('Build done ✔');
});

There is two sorts of processors:

• file processors
• dom processors

File processors

File processors take a list of files as argument.

In the following example, the argument file will contain an array of every png images in the directory. For more information about the Glob pattern.

module.exports = {
  glob: '**/*.png',

  process: function(files, next){
    //...
  }
}

Dom processors

Dom processors take a list of DOM element as argument.

$ is based on a jQuery-like implementation: Cheerio that works on Unix and Windows.

module.exports = {
  el: 'link[data-build] href',

  process: function($, dir, links, next){
    if(!links) return next();
    var keys = Object.keys(links);
    if(!keys.length) return next();
    keys.forEach(function(key){
      var hrefs = links[key];
      //...

    }
  }
}
