json.dump appears to add extraneous spaces before newline characters. By specifying the separators option, we can remove these whitespaces, reducing the diff noise.

treeify 
treeify converts a JS object into a nice, visible depth-indented tree for console printing. The structure
generated is similar to what you get by running the tree command on Unixy platforms.
{
oranges: {
'mandarin': { ├─ oranges
clementine: null, │ └─ mandarin
tangerine: 'so cheap and juicy!' -=> │ ├─ clementine
} │ └─ tangerine: so cheap and juicy!
}, └─ apples
apples: { ├─ gala
'gala': null, └─ pink lady
'pink lady': null
}
}
It also works well with larger nested hierarchies such as file system directory trees.
In fact, the fs_tree example does a pretty good job of imitating tree. Try it out!
See the other included examples or the test suite for usage scenarios.
Getting it
For use with node.js
First you'll want to run this command in your project's root folder:
$ npm install treeify
Then proceed to use it in your project:
var treeify = require('treeify');
console.log(
treeify.asTree({
apples: 'gala', // ├─ apples: gala
oranges: 'mandarin' // └─ oranges: mandarin
}, true)
);
For use in a browser
Treeify cooperates with Node, AMD or browser globals to create a module. This means it'll work
in a browser regardless of whether you have an AMD-compliant module loader or not. If such
a loader isn't found when the script is executed, you may access Treeify at window.treeify.
Usage
The methods exposed to you are as follows, in a strange kind of signature notation:
asLines()
treeify.asLines(obj, showValues (boolean), [hideFunctions (boolean),] lineCallback (function))
// NOTE: hideFunctions is optional and may be safely omitted - this was done to ensure we don't break uses of the previous form
asTree()
treeify.asTree(obj, showValues (boolean), hideFunctions (boolean)): String
Running the tests
There's a pretty extensive suite of Vows tests included.
$ npm test
