plug-auth-client

Client library for third-party authentication with plug.dj.

Installation

npm install --save plug-auth-client

Usage

import { authenticate, httpTransport } from 'plug-auth-client'

authenticate({
  transport: httpTransport({ url: 'https://my-website.com/auth' })
}).then((result) => {
  console.log('done!')
  // Token for doing authenticated requests in `result.token`
}).catch((error) => {
  console.error(`Whelp: ${error.message}`)
})

plug-auth-client uses Promises, which are not supported in Internet Explorer. If you want to support Internet Explorer, also include es6-promise in your script:

// After `npm install --save es6-promise`:
import 'es6-promise'

// or use AMD:
define([
  'https://cdnjs.cloudflare.com/ajax/libs/es6-promise/3.3.1/es6-promise.min.js'
], function () {
  // your code
})

API

authenticate(options: object)

Authenticate with a remote server.

Options:

• transport: A transport instance. Required.
• user: User ID to authenticate as. Defaults to API.getUser().id, which is the current user ID on plug.dj.

httpTransport(options: object)

Create a transport that talks to a plug-auth-server-style HTTP authentication endpoint.

Options:

• url: URL of the endpoint to authenticate to. Use this option if the token and verify steps should both use the same URL, like when using the default plug-auth-server middleware.
• tokenUrl: URL of the endpoint used to get a unique token that will be used to verify the user's identity. Defaults to the value of the url option.
• verifyUrl: URL of the endpoint used to verify the user's identity. Defaults to the value of the url option.

Custom Transports

Transports are objects with a getToken and a verify method.

transport.getToken(options: {user: number})

Generate the verification token that will be put in the user's blurb. Should return a Promise for an object of the shape:

• blurb: Token to store in the blurb.

transport.verify(options: {user: number})

Ask the authentication endpoint to verify the token in the user's blurb. Should return a Promise for an object of the shape:

• token: Authentication token.
