npm install grunt-levin-assets-mapping --save-dev

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

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

Usage Examples

Default Options

In this example, the default options are used to do something with whatever. So if the testing file has the content Testing and the 123 file had the content 1 2 3, the generated result would be Testing, 1 2 3.

grunt.initConfig({
  levin_assets_mapping: {
        options:{
          mapping:'{{= dest}}md5conf.json',
          algorithm:'md5'
        },
        asset:{
            files:[
              {
                  cwd:'test/module1/',
                  src:['**/*.js','**/*.css','**/*.htm','**/*.{jpg,jpeg,gif,png}'],
                  dest:'tmp/module1/',
                  //the module path which dependency 
                  denpendencies:'common/lib.js'
              },
              {
                  cwd:'test/module2/',
                  src:['**/*.js','**/*.css','**/*.htm','**/*.{jpg,jpeg,gif,png}'],
                  dest:'tmp/module2/'
              }
            ]
        }
      }
});

Custom Options

In this example, custom options are used to do something else with whatever else. So if the testing file has the content Testing and the 123 file had the content 1 2 3, the generated result in this case would be Testing: 1 2 3 !!!

grunt.initConfig({
  levin_assets_mapping: {
        options:{
          // default the mapping file name is mapping.json under to user set the dest directory 
          mapping:'{{= dest}}md5conf.json',
          //  default value is md5 
          algorithm:'md5'
        },
        asset:{
            files:[
            // generate mapping file by user set directory 
              {
                  cwd:'test/module1/',
                  src:['**/*.js','**/*.css','**/*.htm','**/*.{jpg,jpeg,gif,png}'],
                  dest:'tmp/module1/'
              },
              {
                  cwd:'test/module2/',
                  src:['**/*.js','**/*.css','**/*.htm','**/*.{jpg,jpeg,gif,png}'],
                  dest:'tmp/module2/'
              }
            ]
        }
      }
  },
});
