Auth Proxy

This is a simple proxy server that enables OAuth authentication for preview environments.

Setup

Deploy it somewhere (Vercel is a one-click, zero-config option) and set the following environment variables:

AUTH_DISCORD_ID - The Discord OAuth client ID
AUTH_DISCORD_SECRET - The Discord OAuth client secret
AUTH_REDIRECT_PROXY_URL - The URL of this proxy server
AUTH_SECRET - Your secret

Make sure the AUTH_SECRET and AUTH_REDIRECT_PROXY_URL match the values set for the main application's deployment for preview environments, and that you're using the same OAuth credentials for the proxy and the application's preview environment. The lines below shows what values should match eachother in both deployments.
