Getting Started

Then add this line to your project's grunt.js gruntfile:

grunt.loadNpmTasks('grunt-data-injector');

Documentation

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.

Options

Here the available options with the corresponding defaults:

# name of the reader - currently `json` or `yaml` available 
source: "json"
 
# name of the formatter - currently only `js` available 
target: "js"
 
# a dot-separated path to select data from the json prior injecting. 
path: ""
 
# only in conjunction with path. Keeps the structure of the selected data if set. 
keepStructure: true
 
# function which will take a filename and return a js object, used to read the data. 
reader: grunt.file.readJSON
 
# string, after which the data will be injected. 
inserter: "{"
 
# function which takes the data and returns a string ready for injection 
formatter: (data,returnType,filename) ->
  formattedData = [returnType+"  // content from "+filename+returnType]
  for k,v of data
    formattedData.push "  var "+k+" = "+util.inspect(v,{depth:null})+";"+returnType
  formattedData.push "  // end of content from "+filename
  return formattedData.join("")

Extensions

If you build your own reader or formatter, I would be happy to include them!
