I wrote a database engine in TypeScript

What it does

SKSQL is a SQL database for the web and node.js written in Typescript. - alexraffy/sksql

In the maker’s words, at launch

Hi! I wanted to understand more about databases' internals so I wrote one from scratch. It has a T-SQL inspired syntax with support for functions and procedures. It can be used stand-alone as a SQL engine or with a server allowing for persistence and replication to other connected clients. Performance are nothing…

  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…

  DBOS TypeScript – Lightweight Durable Execution Built on Postgres2025 · github.com · ▲77

  Hi HN - Peter from DBOS here with my co-founder Qian (qianl_cs) Today we want to share our TypeScript library for lightweight durable execution. We’ve been working on it since last year and recently released v2.0 with a ton of new features and major API overhaul. https://github.com/dbos-inc/dbos-transact-ts Durable execution means persisting the execution state of your program while it runs, so if it is ever interrupted or crashes, it automatically resumes from where it left off. Durable execution is useful for a lot of things: - Orchestrating long-running or…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I'm building an open-source Amazon▲1,335

  A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
