NATS Reviews

Best message queue for cloud-native apps
NATS is designed to be simple and easy to use, with a small footprint and low latency. It is often used in cloud-native environments to connect different components of a distributed system or to enable communication between microservices. NATS also supports message persistence, security, and clustering, making it a robust messaging system for building scalable and resilient...

Are Free, Open-Source Message Queues Right For You?
One challenge of NATS is that it does not support reliable message queuing out of the box - messages can be lost if a client disconnects before it receives them. This can be mitigated by using NATS Streaming, a data streaming system powered by NATS, but it adds complexity.

NATS vs RabbitMQ vs NSQ vs Kafka | Gcore
NATS is known for its high performance, low latency, and emphasis on simplicity after it was rewritten in Go. Its rewrite in Go makes NATS an ideal choice for demanding and real-time applications and has increased its throughput compared to its original Ruby implementation.

  • Implementing OTel Trace Context Propagation Through Message Brokers with Go
    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. - Source: dev.to / 21 days ago

  • Sequential and parallel execution of long-running shell commands
    Pueue dumps the state of the queue to the disk as JSON every time the state changes, so when you have a lot of queued jobs this results in considerable disk io. I actually changed it to compress the state file via zstd which helped quite a bit but then eventually just moved on to running NATS [1] locally.

  • Essential guide to WebSocket authentication
    Of course, if this all sounds like a headache, you might consider Ably. Apart from solving the authentication problem, Ably provides additional features you’d need to implement on top of WebSockets like Presence and message queues, and provides production guarantees that will be time-consuming or costly to achieve on your own like 99.999% uptime guarantee, exactly-once delivery, and guaranteed message ordering. - Source: dev.to / 5 months ago

  • Serverless WebSockets with Ably
    I reached for Ably because they had a booth at the 2022 Jamstack Conf, and probably gave me a sticker or something. (You hear that? Sponsor your local tech conference!) They have a generous free tier, which is an absolute requirement for this space, where devs like me usually want to try a product on something that doesn't make us any money, and then that translates (ideally) into recommending it in our... - Source: dev.to / 8 months ago
  • Cursor Everywhere: An experiment on shared cursors for every website
    A realtime protocol like WebSockets seemed like a logical way to share real-time updates of cursor positions. Working at Ably, it was a no-brainer to use it as my WebSocket-based pub/sub broker. A pub/sub broker simplifies many aspects of projects like this, often coming with built-in features that speed up development. For instance, I wanted each browser's cursor position to be continually available to other... - Source: dev.to / 8 months ago

    So let's get started. Firs thing to do is to create an account in Ably, so head there and create your account. Then, you have to create an application, give it a name, and we are good to go. The next thing to do, is to grab the API key. From the Ably dashboard, head to API Keys, you will find 2 keys, we are interested in the first one. - Source: dev.to / 11 months ago
