ES6 fetch syntactic sugar: handling common fetch usage with json content type, same headers, and stringified body
/*
fetch is awesome, there's no question about it.
But aren't you tired of:
- Writing your `res => res.json()` handler
- Having to stringify your body
- Signin your request with the same headers (```{'Content-Type': json, Authorization: 'JWT ...'}```)
- Inconsistently handling the response status code and not reject promise when relevant.
Usage:
request('http://yourawesome.api.com').then(console.log).catch(console.error);
