  • NATS

    • Project mention: Implementing OTel Trace Context Propagation Through Message Brokers with Go | dev.to | 2024-04-04

    Several message brokers, such as NATS and database queues, are not supported by OpenTelemetry (OTel) SDKs. This article will guide you on how to use context propagation explicitly with these message queues.

  • Apache Pulsar

    Apache Pulsar - distributed pub-sub messaging system

    • Project mention: Choosing Between a Streaming Database and a Stream Processing Framework in Python | dev.to | 2024-02-10

    Stream-processing platforms such as Apache Kafka, Apache Pulsar, or Redpanda are specifically engineered to foster event-driven communication in a distributed system and they can be a great choice for developing loosely coupled applications. Stream processing platforms analyze data in motion, offering near-zero latency advantages. For example, consider an alert system for monitoring factory equipment. If a machine's temperature exceeds a certain threshold, a streaming platform can instantly trigger an alert and engineers do timely maintenance.

  • emqx

    The most scalable open-source MQTT broker for IoT, IIoT, and connected vehicles

    • Project mention: Simplest Guide to DIY Your Own LLM Toy in 2024 | dev.to | 2024-04-02

    • Project mention: Building Llama as a Service (LaaS) | dev.to | 2024-04-08

    Although they did not make it into production, I experimented with the RabbitMQ message broker, Python (Django, Flask), Kubernetes + minikube, JWT, and NGINX. This was a hobby project, but I intended to learn about microservices along the way.

  • Tinode

    Instant messaging platform. Backend in Go. Clients: Swift iOS, Java Android, JS webapp, scriptable command line; chatbots

  • ZeroMQ

    ZeroMQ core engine in C++, implements ZMTP/3.1

    • Project mention: Lightweight and fast AMQP (0-9-1) server | news.ycombinator.com | 2024-04-07

    Slightly OT:

    Are ZeroMQ and NanoMQ still widely used (and recommended)?

  • Asynq

    Simple, reliable, and efficient distributed task queue in Go

    • Project mention: Looking for a language agnostic Go task queue with Redis | /r/golang | 2023-09-12

    EDIT : I think the best for my case will be to use the asynq library with a custom js client, it's quite easy to implement (Detailed here)

  • Centrifugo

    Scalable real-time messaging server in a language-agnostic way. Self-hosted alternative to Pubnub, Pusher, Ably. Set up once and forever.

    • Project mention: WebSockets vs. Server-Sent-Events vs. Long-Polling vs. WebRTC vs. WebTransport | news.ycombinator.com | 2024-03-20

    Hello, I am author of https://github.com/centrifugal/centrifugo. Our users can choose from WebSocket, EventSource, WebTransport (experimental stabilize in the future). WebRTC is out of scope as the main purpose is central server based real-time json/binary messaging, and WebRTC makes things much more complex since it shines for peer-to-peer and rich media communications.

    What I'd like to add is that Centrifugo also supports HTTP-streaming – not mentioned by the OP – but this is a transport which has advantages over Eventsource - like possibility to send POST body on initial request from web browser (with SSE you can not), it supports binary, and with Readable Streams browser API it's widely supported by modern browsers.

    Another thing I'd like to mention about Centrifugo - it supports bidirectional WebSocket fallbacks with EventSource and HTTP-streaming, and does this without sticky sessions requirement. I guess nobody else have this at this point. See https://centrifugal.dev/blog/2022/07/19/centrifugo-v4-releas.... Which solves one more practical concern. Sticky sessions is an optimization in Centrifugo case, not a requirement.

    If you are interested in topic, we also have a post about WebSocket scalability - https://centrifugal.dev/blog/2020/11/12/scaling-websocket - it covers some design decisions made in Centrifugo.

  • watermill

    Building event-driven applications the easy way in Go.

    • Project mention: Microservices communication | /r/golang | 2023-12-09

    I’ve successfully worked on projects using an asynchronous event-driven way of connecting services. I really like the decoupling of business logic and the events triggering it. I highly recommend https://github.com/ThreeDotsLabs/watermill to be more flexible when it comes to choosing the actual technology driving the async patter. It might be NATS today but requirements might change and you need to change. Watermill prepares you for this.
