financial-timesfetchres 
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 fetchresOr
bower install --save fetchresUsage (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;
}
