npm Version Maintainability

Getting started

Prerequisits

Requires node v18 and Integreat v1.0.

Installing and using

Install from npm:

npm install integreat-authenticator-oauth2

Example setup with refresh token grant type:

import Integreat from 'integreat'
import oauth2 from 'integreat-authenticator-oauth2'

const defs = {
  auths: {
    id: 'service-oauth2',
    authenticator: 'oauth2',
    options: {
      grantType: 'refreshToken',
      uri: 'https://api.service.test/oauth/v1/token',
      key: 'client1',
      secret: 's3cr3t,
      redirectUri: 'https://service.test/cb,
      refreshToken: 't0k3n',
    }
  },
  schemas: [ /* your schemas */ ],
  services: [
    {
      id: 'service-with-oauth2',
      transporter: 'http',
      adapters: ['json'],
      auth: 'service-oauth2',
      endpoints: [ /* your endpoints */ ],
    },
  ],
}

const resources = {
  authenticators: {
    oauth2,
  },
  /* your other resources */,
}

const great = Integreat.create(defs, resources)

An auth def with the client credentials grant type could look like this:

const def = {
  auths: {
    id: 'service-oauth2',
    authenticator: 'oauth2',
    options: {
      grantType: 'clientCredential',
      uri: 'https://api.service.test/oauth/v1/token',
      key: 'client1',
      secret: 's3cr3t',
    },
  },
}

An auth def with the client credentials grant type could look like this:

const def = {
  auths: {
    id: 'service-oauth2',
    authenticator: 'oauth2',
    options: {
      grantType: 'jwtAssertion',
      uri: 'https://api.service.test/oauth/v1/token',
      key: 'client1',
      secret: privateKey, // In case of RS256, this needs to be the complete private key file
      scope: 'all',
      audience: 'https://api.service.test/oauth/v1/token',
      algorithm: 'RS256',
      expiresIn: 3600,
    },
  },
}

All grant types may include a scope options, which is a space delimited string of scope keywords, defined by the targeted service.
