Node-Inline-Assets

Node API, CLI and Grunt Task
for inlining external assets of HTML/CSS files.

Abstract

This is a Node Application Programming Interface
(API), Command-Line Interface (CLI) and Grunt Task for inlining all
external assets of HTML/CSS files. The purpose of this approach is
to either reduce the number of required HTTP requests for HTML5
Single-Page-Apps (SPA) or to simply bundle a stand-alone HTML document
with all its external assets for easier distribution.

Installation

Use the Node Package Manager (NPM) to install this module
locally (default) or globally (with option -g):

$ npm install [-g] inline-assets

Usage

Command-Line Interface (CLI)

$ inline-assets \
  [--verbose] \
  [--htmlmin] [--cssmin] [--jsmin] \
  [--pattern <filename-regex>] \
  [--purge] \
  <source-file> [<destination-file>]

Grunt Build Process

grunt.initConfig({
    "inline-assets": {
        options: {
            verbose: false,
            htmlmin: false,
            cssmin:  false,
            jsmin:   false,
            pattern: [ ".+" ],
            purge:   false
        },
        "example": {
            src:  "<source-file>",
            dest: "<destination-file>"
        },
        [...]
    },
    [...]
})

Application Programming Interface (API)

var fs = require("fs")
var inlineAssets = require("inline-assets")
var content = fs.readFileSync("<source-file>", "utf8")
content = inlineAssets("<destination-file>", "<source-file>", content, {
    verbose: false,
    htmlmin: false,
    cssmin:  false,
    jsmin:   false,
    pattern: [ ".+" ],
    purge:   false
})
fs.writeFileSync("<destination-file>", content, "utf8")

Options

The processing options are:

verbose: Print verbose processing information.
htmlmin: Minify processed HTML content (with html-minifier).
cssmin: Minify processed CSS content (with csso).
jsmin: Minify processed JavaScript content (with uglify-js).
pattern: Comma-separated list of positive/negative filename regex patterns.
purge: Purge HTML/CSS/JavaScript references of files excluded by pattern.
