digest auth request plugin for fetch/node-fetch, supports http basic authentication as well

Installation

// dependencies for node
npm install node-fetch

// for browers, if to use it directly, please indcude file `digest-fetch.js` in a <script/> 
<script type="application/javascript" src="path-to-digest-fetch.js'></script>

Get Started

const DigestFetch = require('digest-fetch')
// In browser: const DigestFetch = window.DigestFetch;

Initialize with option and credential

const digestOptions = {
  cnonceSize: 32,    // length of cnonce, default: 32
  logger: console,   // logger for debug, default: none
  algorithm: 'MD5',  // algorithm to be used, 'MD5' or 'MD5-sess'

  // Custom authentication failure code for avoiding browser prompt:
  // https://stackoverflow.com/questions/9859627/how-to-prevent-browser-to-invoke-basic-auth-popup-and-handle-401-error-using-jqu
  statusCode: 401,   // default 401

  basic: false       // we support http basic authentication as well, enable it here if you want, default: false
}

const client = new DigestFetch('user', 'password', digestOptions) 

const basic_auth_client = DigestFetch('user', 'password', { basic: true })

Do request same way as fetch or node-fetch

const url = ''
const options = {}
client.fetch(url, options)
  .then(resp=>resp.json())
  .then(data=>console.log(data))
  .catch(e=>console.error(e))

Pass in refresh request options factory function for conditions options needs be refreshed when trying again. For example when posting with file stream:

const factory = () => ({ method: 'post', body: fs.createReadStream('path-to-file') })
client.fetch(url, {factory})
  .then(resp=>resp.json())
  .then(data=>console.log(data))
  .catch(e=>console.error(e))
