Indent JSON with JavaScript
Working with XML and JavaScript is a nightmare, which is why JSON has become gold in the development community. Hell, I even wrote a function to turn XML to JSON with JavaScript. If you want to turn an existing object into well formatted JSON, you can you JSON.stringify(obj), but you already know that. What you may not know is that you can do pretty formatting when generating JSON from objects!
The secret is using the third JSON.stringify argument which represents the space indentation levels:
var formatted = JSON.stringify(myObject, null, 2);
/*
Result:
{
"myProp": "myValue",
"subObj": {
"prop": "value"
}
}
*/
The resulting JSON representation will be formatted and indented with two spaces!
![fetch API]()
One of the worst kept secrets about AJAX on the web is that the underlying API for it, XMLHttpRequest, wasn't really made for what we've been using it for. We've done well to create elegant APIs around XHR but we know we can do better. Our effort to...
![How to Create a Twitter Card]()
One of my favorite social APIs was the Open Graph API adopted by Facebook. Adding just a few META tags to each page allowed links to my article to be styled and presented the way I wanted them to, giving me a bit of control...
![Upload Photos to Flickr with PHP]()
I have a bit of an obsession with uploading photos to different services thanks to Instagram. Instagram's iPhone app allows me to take photos and quickly filter them; once photo tinkering is complete, I can upload the photo to Instagram, Twitter, Facebook, and...
![CSS Filters]()
CSS filter support recently landed within WebKit nightlies. CSS filters provide a method for modifying the rendering of a basic DOM element, image, or video. CSS filters allow for blurring, warping, and modifying the color intensity of elements. Let's have...
For more advanced formatting, I’ve developed a tool for the intent:

It works a client library or a server module for node/io.js, has a CLI, and a Grunt and a Gulp plugin.
Of course, if you need speed just use
JSON.stringify.Sorry for the self-promotion.
You can also format a JSON file in the terminal with a single command.
