useref
Parse build blocks in HTML files to replace references
Extracted from the grunt plugin grunt-useref.
Installation
npm install node-useref
Usage
useref = require('node-useref')
var result = useref(inputHtml)
// result = [ replacedHtml, { type: { path: { 'assets': [ replacedFiles] }}} ]Blocks are expressed as:
<!-- build:<type>(alternate search path) <path> -->
... HTML Markup, list of script / link tags.
<!-- endbuild -->- type: either
js,cssorremove - alternate search path: (optional) By default the input files are relative to the treated file. Alternate search path allows one to change that
- path: the file path of the optimized file, the target output
An example of this in completed form can be seen below:
<html>
<head>
<!-- build:css css/combined.css -->
<link href="css/one.css" rel="stylesheet">
<link href="css/two.css" rel="stylesheet">
<!-- endbuild -->
</head>
<body>
<!-- build:js scripts/combined.js -->
<script type="text/javascript" src="scripts/one.js"></script>
<script type="text/javascript" src="scripts/two.js"></script>
<!-- endbuild -->
</body>
</html>The module would be used with the above sample HTML as follows:
var result = useref(sampleHtml)
// [
// resultHtml,
// {
// css: {
// 'css/combined.css': {
// 'assets': [ 'css/one.css', 'css/two.css' ]
// }
// },
// js: {
// 'scripts/combined.js': {
// 'assets': [ 'css/one.js', 'css/two.js' ]
// }
// }
// }
// ]The resulting HTML would be:
<html>
<head>
<link rel="stylesheet" href="css/combined.css"/>
</head>
<body>
<script src="scripts/combined.js"></script>
</body>
</html>
