grunt-sourcemap-modifier

A Grunt task for Closure Compiler Source Maps modifications. By default Closure Compiler hardcode path to source and file during compilation. It's easy to solve using Makefiles but it's quite inconvenient using Grunt.

Getting Started

First you need to have a task which care about Closure Compiler. You can use Grunt Closure Compiler task or fork by me with bunch of fixes.

Then register the task by adding the following line to your grunt.js gruntfile:


grunt.loadNpmTasks('grunt-sourcemap-modifier');

Then you can minify JavaScript calling:


grunt.initConfig({
  "sourcemap-modifier": {
    main: {
      files: [
        "build/*.map"
      ],
      base: {
        "build/": "",
        "lib/": "../lib/"
      },
      fileBase: {
        src: "build/",
        dst: ""
      }
    }
  }
});

Sections

First level sections used as group name for multiple tasks and its names not really matters.

Here is list of important sections:

  • files - section should be provided with mask of sourcemap filenames
  • base - list of filenames map where object key is actual path built by Closure Compiler and value is target path which should appear modification
  • fileBae - single modifier of file key within source map where
    • src - current path prefix build by Closure Compiler
    • dst - destination path which should appear after modification
