Example

Assume you have the following file structure:

data\
  somefile.json
  subdir\
    anotherfile.json
js\
  somefile.js
  subdir\
    anotherfile.js

than this task

dataInjector:
  options:
    # change options on global level 
  compile:
    options:
      # change options on task level 
    files: [
      expand: true,
      cwd: "data/",
      src: ["**/*.json"],
      ext: ".js",
      dest: "js/"   
    ]

would inject the data from the .json files into the corresponding .js files.
