var inline = require('gulp-inline')
  , uglify = require('gulp-uglify')
  , minifyCss = require('gulp-minify-css');

gulp.src('public/index.html')
  .pipe(inline({
    base: 'public/',
    js: uglify,
    css: minifyCss,
    disabledTypes: ['svg', 'img', 'js'], // Only inline css files
    ignore: ['./css/do-not-inline-me.css']
  }))
  .pipe(gulp.dest('dist/'));

Replaces your <script> and <link> tags with the corresponding inlined files.

Currently there are two supported methods:

• <img> element with src attribute:

  <img src="/assets/icon.svg" class="MyClass" />
  

  which will be converted to something like

  <svg xmlns="http://www.w3.org/2000/svg" viewbox="..." class="MyClass">
    <circle ... />
    <path ... />
    etc.
  </svg>
  

  depending on what /assets/icon.svg contains

• <svg> element with <use> child element:

  <svg>
    <use xlink:href="/assets/icon.svg#MyIdentifier"></use>
  </svg>
  

  Note that this method requires an ID matching the ID of target SVG root element.

  This is valid target SVG for the example above:

  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32" id="MyIdentifier">
    ...
  </svg>
  

  while this is invalid:

  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
    ...
  </svg>
  

Plugin options:

• base - the root directory containing the files to be inlined
• css - css transform (gulp plugin)
• js - js transform (gulp plugin)
• svg - svg transform (gulp plugin)
• ignore - array of file paths to ignore and not inline (file paths as they appear in the source)
• disabledTypes - array of types not to run inlining operations on (css, svg, js, img)
