Example app to demonstrating issues with OAuth2 + Linode. It appears Linode requires certain headers to be set else Linode returns a 403 status with an error. The error looks like:
InternalOAuthError: Failed to obtain access token

- Create an OAuth app in Linode with the following settings:
- Name: your choice, doesn't matter
- Callback URL:
http://localhost:3000/auth/callback
- Install dependencies:
npm install
- Run app by using the
npm startcommand and setting CLIENT_ID, CLIENT_SECRET, and CALLBACK_URL env vars from Linode OAuth application created in step 1:
CLIENT_ID={client-id-here} CLIENT_SECRET={client-secret-here} CALLBACK_URL={callback-url-here} npm start
docker build -t linode-oauth-express .
docker run -p 3000:3000 -e CLIENT_ID=your_client_id -e CLIENT_SECRET=your_client_secret -e CALLBACK_URL linode-oauth-express
