CatMap

A simple package to convert a file mapping configuration into a file map that can be used for minification or concatenation build tasks. Works by appending a common "source directory" to the beginning of a set of files to avoid having to maintain lengthy lists of source to destination mappings in build configuration.

Motivated by my laziness.

Format

example_config.cson
 
app:
  options: srcDir: '.tmp/app'
  files:
    # Main Application Code #
    'public/app/app.js': [
      'app.module.js'
      'app.routes.js'
      'app.directives.js'
      'app.controller.js'
    ]
 
    # User Authentication Components #
    'public/app/auth.js': [
      'components/auth/singupController.js'
      'components/auth/signinController.js'
      'components/auth/authService.js'
    ]
 
libs:
  options: srcDir: 'bower_modules'
  files:
    'public/lib/vendor.min.js': [
      'angular/angular.min.js'
      'angular-resource/angular-resource.min.js'
      'angular-ui-router/release/angular-ui-router.min.js'
    ]

Usage

const catmap = require('catmap');
 
let filemapping = catmap('./example_config.cson');
 
// Or if you prefer JSON
 
let filemapping = catmap('./example_config.json');
 
// filemapping =>
{
  'public/lib/vendor.min.js': [
    'bower_modules/angular/angular.min.js',
    'bower_modules/angular-resource/angular-resource.min.js',
    'bower_modules/angular-ui-router/release/angular-ui-router.min.js'
  ],
  'public/app/app.js': [
    '.tmp/app/app.module.js',
    '.tmp/app/app.routes.js',
    '.tmp/app/app.directives.js',
    '.tmp/app/app.controller.js'
  ],
  'public/app/auth.js': [
    '.tmp/app/components/auth/singupController.js',
    '.tmp/app/components/auth/signinController.js',
    '.tmp/app/components/auth/authService.js'
  ]
}

Example: Grunt Uglify

const catmap = require('catmap');
 
uglify: {
  production: {
    files: catmap('config/fileConcatMappings.cson')
  }
}
