@rray/oauth2

A very simple OAuth2 implementation

Global fetch expectation

Note: this package expects a global fetch to be set, which is present on newer Node.js versions.

It can be polyfilled with node-fetch, for example.

Usage

import { OAuth2 } from './oauth2.mjs'

// provides { full_auth_url, async auth(code) }
const oauth = OAuth2('google', { g_client_id, g_client_secret, g_redirect_uri })

server.get('/oauth', (req, res) => res.redirect(oauth.full_auth_url))

server.get('/oauth/callback', async (req, res) => {
  const userinfo = await oauth.auth(req.query.code)
  ...
})

Providers support

Currently two providers have built-in support: 'google' and 'yandex'.

In order to use this with another provider, just pass in the corresponding provider object manually:

const provider = { ... }
const oauth = OAuth2(provider, { client_id, client_secret, redirect_uri })

See providers list for the structure of the provider object.
