This is a simple proxy server that enables OAuth authentication for preview environments.
Deploy it somewhere (Vercel is a one-click, zero-config option) and set the following environment variables:
AUTH_DISCORD_ID
- The Discord OAuth client IDAUTH_DISCORD_SECRET
- The Discord OAuth client secretAUTH_REDIRECT_PROXY_URL
- The URL of this proxy serverAUTH_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.
