response-callbacks

Manually dealing with responses can be tedious and memorizing what every code means isnt something i enjoy doing. So I put together a list of common callbacks that can be used with the response object.

Install

npm install --save response-callbacks

Example Usage

response-callbacks takes in two parameters. Response and an object containing methods you want called back to.

import RepsonseCallbacks from 'response-callbacks'

let callBacks = {
  success: (response) => { console.log('success', response) },
  validation: (response) => { console.log('form validation errors', response.json()) },
  server_error: (response) => { console.log('server error', response.status) },

  // You can use the status code directly as well.
  420: (response) => { console.log('Enhance Your Calm') }
}

let request = fetch('/endpoint').then((response) => {
  return (new ResponseCallbacks(response, callBacks)).run()
})

// response-callbacks returns the original response so you can continue using promises like normal
request.catch(function (err) { console.error('error', err.message) })

Callback Methods

I put together a list of most used methods. Optionally you can just have the actual status code in your object and it will be called as well.
