grunt-bust-cache GitHub version Build Status

Grunt task to automate your cache-bust configuration

Getting Started

This plugin requires Node 4.x.x and Grunt 1.x.x

Install

$ npm install --save-dev grunt-bust-cache

The "bustCache" task

Use the bustCache task for cache busting static files in your application. This allows the assets to have a large expiry time in the browsers cache and will only be forced to use an updated file when the contents of it changes.

This plugin supports:

  • Hash calculation in multiple formats
  • Multiple cache bust methods (including RequireJS's urlArgs)

Example Usage

bustCache: {
  dev: {
    options: {
      hashType: "timestamp", // git, npm, maven, timestamp
      css: true,
      requireJs: true,
      javascript: false
    },
    src: "path/to/your/projects/index.html"
  },
  prod: {
    options: {
      hashType: "maven", // git, npm, maven, timestamp
      css: true,
      requireJs: true,
      javascript: true
    },
    src: "path/to/your/projects/index.html"
  }
}

Supported File Paths

bustCache: {
  foo: {
    // Path to a single file
    src: "path/to/your/projects/index.html"
  },
  bar: {
    // Specify both source and destination
    src: "path/to/your/source/file.html", // Can be string or array
    dest: "path/to/your/destination/file.html"
  },
  baz: {
    // Specify multiple file pairs
    files: [
      {
        src: "path/to/your/source/file.html",
        dest: "path/to/your/destination/file.html"
      }
    ]
  }
