grunt-web-stamp

v0.5.0 has removed some options and fixed some bugs.

Add timestamp to the url path.It searches <img/>,<link/>,<script/> and url() to resolve every path and calculates timestamp to append to it.

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-web-stamp --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-web-stamp');

The "stamp" task

Overview

In your project's Gruntfile, add a section named stamp to the data object passed into grunt.initConfig().

grunt.initConfig({
  stamp: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

baseDir

Type: String Default value: '.'

A string value that is indicating where the resource files are.

You can assign a function instead:

{
    baseDir:function(targetFilePath){return "static/";}
}

prefix

Type: String or Function Default value: ''

A string value that will be prepended to each url path.If it's defined as a function,real filepath will be passed in as the only parameter.Ex:

prefix:function(filepath){return /\.css$/.test(filepath)?'cdn_css':'cdn_js';}

pattern
