How to generate a single optimized html file from web a project?

Question

I have a typical web page with a single html file. This page uses css, javascript modules (requirejs) and images. I would like to generate a single html file containing all the resources embedded and minified including the html file itself.

This is the structure that I have:

myApp/
   www/
      css/
          css1.css
          css2.css
      img/
          img1.png
          img2.png
      js/
          main.js
          module1.js
      index.html

And I would like to generate this:

myApp/
   www-build/
      index.min.html

I know that exists different tools to optimize javascripts, css and html. But the question is how to assemble them in a single file automaticaly.

Answer 1

I ended up using gruntjs and a series of grunt tasks to do the job:

• A Jade template with the include directive to import js and css.
• grunt-base64 To convert the images to base64.

The jade file, would be some thing like this:

html
    head
        title= "Example Page"
        include css/css1.css
        include css/css2.css
        include js/main.js
        include js/module1.js

    body
        | <img src="data:image/png;base64,
        include img1.b64
        | "/>

        | <img src="data:image/png;base64,
        include img2.b64
        | "/>

        canvas#myCanvas 

I also used uglify and other excellent predefined tasks to optimize the code.
