digest auth request plugin for fetch/node-fetch also supports http basic authentication
For digest-fetch 3.0.0 or above
``sh
npm install digest-fetch@latest node-fetch@latest
`
For digest-fetch 2.0.3 or below
`sh
npm install digest-fetch@v2 node-fetch@v2
`
`js
// Use require for digest-fetch 2.0.3 or below
const DigestClient = require('digest-fetch')
// Use import
import DigestClient from "digest-fetch"
`
#### Typescript
For digest-fetch 3.0.0 or above
Since digest-fetch becomes ES module starting 3.0.0, you need to set your project as module to use import.
- Specify `"type": "module"` in your package.json`
- Specify --esm` for ts-node like `npx ts-node --esm src/index.ts`
- Specify "module": "ESNext", "moduleResolution": "node"` in your tsconfig.json
`sh
// Install dependencies
npm install digest-fetch@latest node-fetch@latest
// Import
import DigestClient from "digest-fetch"
`
For digest-fetch 2.0.3 or below
`sh
// Install dependencies
npm install digest-fetch@v2 node-fetch@v2
// Import
import DigestClient from "digest-fetch"
`
#### Http Basic Authentication
Create a client using basic authentication challenge
`js`
const client = new DigestClient('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
`js`
const client = new DigestClient('user', 'password')
Specify options for digest authentication
` js`
const client = new DigestClient('user', 'password', { algorithm: 'MD5' })
Supported Algorithm
`js`
['MD5', 'MD5-sess', 'SHA-256', 'SHA-256-sess', 'SHA-512-256', 'SHA-512-256-sess']
Options fields:
| field | type | default | description |
| :------------- | :---------- | :-----------: | :---------- |
| algorithm | string | 'MD5' | algorithm to be used: 'MD5', 'SHA-256', 'SHA-512-256' or with '-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 |

+ 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
`js`
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:
`js``
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))
