broccoli-tree-to-json

Roll up a directory tree into a JSON document.

The directory structure:

root
|--key1.txt #123
|--key2.txt #val2
+--subdir
   |--key3.txt #true
   |--key4.txt #val4

Will result in the following json:

//destDir/root.json
{
  "key1":123,
  "key2":"val2",
  "subdir":{
    "key3":true,
    "key4":"val4"
  }
}

The file extension is ignored. The JSON key is determined by the portion of the file to the left of the first dot.

File contents are parsed by JSON.parse, and if that fails the contents of the file is treated like a string.

TODO

• Better Array support

Example use

In a Brocfile:

//Brocfile.js
var tree2Json = require('broccoli-tree-to-json');

module.exports = tree2Json('interesting/path');

Within another plugin

//index.js
var tree2Json = require('broccoli-tree-to-json'),
  path = require('path');

function MyPlugin(inputTree){
  this.jsonTree = tree2Json(path.join(inputTree, 'json'));
}

MyPlugin.prototype.read = function(readTree){
  return readTree(this.jsonTree)
    .then(function(){
      //...
    });
};

module.exports = MyPlugin;
