Readme

fetchres Build Status
Some useful response handlers for using Fetch API in the real world.
Warning: doesn't come with Fetch or Promise, so you'll need to bring your own polyfill (unless you're using this module within Service Workers, where both fetch and Promise are already defined).

Installation

npm install --save fetchres

Or
bower install --save fetchres

Usage (node)

```js var fetchres = require('fetchres');
fetch('https://mattandre.ws/my-json-endpoint')
.then(fetchres.json)
.then(function(data) {
	// `data` is an object containing the data
	// from the response, not a Response object
	console.log(data);
})
.catch(function(err) {
	if (err.name === fetchres.BadServerResponseError.name) {
		// just a dodgy response
		console.error(err);
	} else if (err.name === fetchres.InvalidJsonError.name) {
		// malformed json, probably
		console.error('malformed json returned');
	} else {
		// something more serious could be wrong.
		// probably want to investigate / send to
		// error aggregation service
		debugger;
	}
});
