a minimal, no bs, link shortener for your domain, that shortens links and nothing more

written in next.js, uses auth.js to log in with github, which is by far the best social login, and links are stored in redis for fast retrieval

1. set up an oauth app with github. set the redirect url to yourdomain.com/api/auth/callback/github

2. set the following env vars

AUTH_GITHUB_ID - your github client id

AUTH_GITHUB_SECRET - your github client secret

ALLOWED_EMAIL - your github email

BASE_REDIRECT_URL - where to redirect when no link is provided. you don't need to do this if you want it to redirect to the admin page

AUTH_SECRET - generate this with openssl rand -hex 32

REDIS_URL - url of a redis instance

3. deploy somewhere like vercel

if DEMO_MODE=true is set, authentication is disabled. DO NOT USE THIS IN PRODUCTION

you can test this out with the demo docker compose stack, just run

docker-compose -f docker-compose.demo.yml up
