svix-webhooks

66 2,075 9.6 Rust

The enterprise-ready webhooks service 🦀

Project mention: Show HN: Hatchet – Open-source distributed task queue | news.ycombinator.com | 2024-03-08

That's exactly why we built Svix[1]. Building webhooks services, even with amazing tools like FastAPI, Celery and Redis is still a big pain. So we just built a product to solve it.
Hatchet looks cool nonetheless. Queues are a pain for many other use-cases too.

mqtt-broker

2 136 3.8 Rust

A tokio-based MQTT v5 broker written in pure Rust [WIP]

Project mention: Announcing rumqttd v0.15.0 with MQTTv5 features like Topic Alias and Message Expiry | /r/rust | 2023-05-30

Not sure if I have many insights that the rumqttd team doesn't already know. My goals were a lot more scaled back in nature, I just wanted an easily-deployable binary that runs on a single machine, there isn't any clustering or things of that sort. Here's the current code. The main thing I'm wondering about is whether I got the architecture right for getting the best performance out of tokio. I have an ESP32-based project I originally wrote this for and I got it to the point where it works, and that's about where I stopped working hard on it, haha

notiflux - subscribe over WebSockets, publish over REST

Project mention: Ask HN: What was an interesting project you started and finished over a weekend? | news.ycombinator.com | 2024-04-06

It was actually couple of weeks ago, but a small project that took mostly just two days to put together and I'm pretty happy with how it turned out.
Notiflux (https://github.com/ikornaselur/notiflux): a small WebSocket broadcast server, the idea being that clients connect with WebSocket (such as a website) and then any source can send a POST request to the API to broadcast messages, allowing for real-time functionality from servers that don't support WebSockets, or you might have multiple sources that each might broadcast messages.
Auth is done by Notiflux having a public key and the sources have the corresponding private key, JWT tokens signed with the private key include topics and scope (subscribe or broadcast to the topics). Clients would auth with an API for example, get a JWT with maybe a 10 second expiry, use it to subscribe to the topics that the API would then broadcast to through Notiflux.
It was an excuse as well to play with WebSocket in Rust and learn a little bit about the Actor Pattern.
If I would continue I'd want to explore how well it scales, how much traffic it could handle and look into horizontal scaling, but I feel like it's complete enough as a toy project.
