digest-fetch

digest auth request plugin for fetch/node-fetch also supports http basic authentication

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

// Use require
const DigestFetch = require('digest-fetch')

// Use import
import * as DigestFetch from "digest-fetch"

// In browser
const DigestFetch = window.DigestFetch;

Http Basic Authentication

Create a client using basic authentication challenge

const client = new DigestFetch('user', 'password', { basic: true })
client.fetch(url, options).then(res => res.json).then(console.dir)

Digest Access Authentication

Create a digest authentication request client with default options

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

Specify options for digest authentication

const client = new DigestFetch('user', 'password', { algorithm: 'MD5' }) 

Options fields:

field	type	default	description
algorithm	string	'MD5'	algorithm to be used: 'MD5' or 'MD5-sess'
statusCode	number	401	custom alternate authentication failure code for avoiding browser prompt, see details below
cnonceSize	number	32	length of the cnonce
logger	object	none	logger for debug, can use console, default no logging
basic	bool	false	switch to use basic authentication
precomputeHash	bool	false	wether to attach hash of credentials to the client instance instead of raw credential

Details:

• When using digest authentication in browsers, may encounter prompt window in foreground. Check: https://stackoverflow.com/questions/9859627/how-to-prevent-browser-to-invoke-basic-auth-popup-and-handle-401-error-using-jqu

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))
