Turns

<link rel="stylesheet" href="css/styles.css">
<script src="js/main.js"></script>

<link rel="stylesheet" href="css/styles-c9a7c7ed62.css">

Hash is MD5 of the content.

Usage

npm install hash-resources

Default settings (link and script tags with -hash appended to file name)

hash-resources example/index.html > example/index.after.html

Explicit config matching default settings

hash-resources --selector=link@href --selector=script@src --name="{path}-{hash}{extension}" example/index.html > example/index.after.html

Path, hash and extension are variables from which you can construct a file name. Extension already contains a dot (.)

Hash in query param

hash-resources --query=v example/index.html > example/index.after.html
