Minimal OAuth Test Client

This is just about the most minimalistic OAuth client possible. It's intended for use in testing Clerk's OAuth server endpoints.

To get it going

• Create an OAuth application in your Clerk dashboard, enter in http://localhost:3000/oauth_callback as the callback url
• Run cp .env.sample .env and fill out the OAuth client id, secret, and your clerk publishable key
• Run npm start

Doing other stuff

• Hit /refresh to refresh the access token
• Hit /userinfo to get back info about the user that authorized the token
• Hit /tokeninfo to get back info about the refresh token
