Suites – modern unit tests framework for TypeScript back ends

In plain words

Suites is a unit-testing framework for TypeScript backends that use dependency injection. It provides a single declarative API to wrap units and automatically generate correct test environments with their dependencies. Developers can test classes in complete isolation with all dependencies mocked, or test integration with real dependencies selectively. Built for teams writing large numbers of backend tests, it reduces boilerplate code and improves maintainability.

  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…

  For the past few months we’ve been building a simple jest/typescript-based high-level language for writing and running integration tests. We're open-sourcing it now and are excited to share it with you: https://github.com/traceloop/jest-opentelemetry Why we built this: - There are many solid frameworks for FE / browser testing, but none with high-level constructs for testing BE flows - We were missing a way to validate side effects for complex backend systems, especially across async queueing systems Our beta version lets you send an API call to a system and…

  Talanoa▲343

  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…
