Checkpoint 401 – forward auth server in TypeScript / Deno

I wrote a forward auth server in TypeScript and Deno. I've written several forward auth servers before but they have always been specifically written for that application. I wanted something more generalised that I could re-use. What is forward auth? Web servers likes Nginx and Caddy and Traefik have a configuration option in which inbound requests are sent to another server before they are allowed. A 200 response from that server means the request is authorised, anything else results in the web server rejecting the request. This is a good thing because it means you can put all your auth…

  • Typebase – A single-folder back end you write in TypeScriptAug 2026 · typebase.io · ▲119

    Hey HN! I built Typebase, a library that gives you Convex's DX with Supabase's openness. After trying Supabase I liked how fast it is to spin up a DB and auth, but really didn't like using RLS and SQL for authorization. With Convex I loved how your server "lives" in your code, but disliked the DB model and the realtime-first defaults. With Typebase you just write TS files inside a typebase/ folder in your existing repo. You can define your DB tables inside a schema.ts file and export server functions that your frontend calls like local functions, fully typed. Auth is built in. Then one…

    Hey all, Andy from the Deno team here. We're excited to share with you Deno Subhosting, an easy way to extend your platforms functionality by securely running untrusted JavaScript written by your users. When we first launched Deno Deploy in 2021, we were surprised at the volume of requests from companies about getting access to the APIs needed to run Deno Deploy. Many companies wanted to give their users the ability to write custom logic in their app, but setting this up in the cloud presents security concerns and a ton of infra work/maintenance. We realized that there was an…
