    • Project mention: Setting up a WebSocket server in Node.js | dev.to | 2024-03-25

    Before setting up a WebSocket server in Node.js, we need to install the necessary dependencies. Fortunately, Node.js has a vibrant ecosystem with various WebSocket libraries available. In this article, we will focus on using the popular ws library, which provides a simple and efficient WebSocket implementation for Node.js.

    • Project mention: You don't need analytics on your blog | news.ycombinator.com | 2023-12-24

    If one wants server-side metrics with a little more info than the author's "hacky little script", there's always goaccess [1], which functions in broadly the same way. I even use it with Firebase Hosting-hosted sites via [2] (which I wrote).

  • µWebSockets

    Simple, secure & standards compliant web server for the most demanding of applications

    • Project mention: I'm open-sourcing my game engine | news.ycombinator.com | 2023-12-19

    They use (uWebSockets)[https://github.com/uNetworking/uWebSockets], which was written in C++, but has an interface to use in NodeJS. It's been really performant for me in my simple tests compared to other popular websocket libs that slow down fairly quickly.

  • instant-ngp

    For backend this might help https://feathersjs.com. I’m not affiliated with them, just a happy user.

  • doris

    Apache Doris is an easy-to-use, high performance and unified analytics database.

    • Project mention: Variant in Apache Doris 2.1.0: a new data type 8 times faster than JSON for semi-structured data analysis | dev.to | 2024-03-27

    As an open-source real-time data warehouse, Apache Doris provides semi-structured data processing capabilities, and the newly-released version 2.1.0 makes a stride in this direction. Before V2.1, Apache Doris stores semi-structured data as JSON files. However, during query execution, the real-time parsing of JSON data leads to high CPU and I/O consumption in addition to high query latency, especially when the dataset is huge and complicated. Moreover, the lack of a pre-defined schema means there is no handle for query optimization.

  • fprime

    • Project mention: Ask HN: Anyone Waiting on BT Auracast? | news.ycombinator.com | 2023-12-16

    Hey folks. Anyone out there waiting for BT Auracast? It was announced June 2022, and immediately struck me as must have.

    I lost my earbuds, but it seems ridiculous to get a replacement without Auracast, seems like surely if I'm going to make a decent sized purchase like that it needs to support group playing. I want to tune into the radios of other people on the metro or on the bus, want to be able to watch a movie on the plane with someone.

    Auracast was announced in June 2022. Anyone else out there struggling with expectations here? I'm really hoping the product announcement season that's right around the corner had a good number of Auracast announcements.

    Side note, a ton of it is over my head but it's been so so fun tuning in every once and again to see how Zephyr's Bluetooth Audio work is going. Just wild now much has gone into this! https://github.com/zephyrproject-rtos/zephyr/commits/main/subsys/bluetooth/audio

  • rt-thread

    RT-Thread is an open source IoT real-time operating system (RTOS).

  • sockjs-client

    WebSocket emulation - Javascript client

    • Project mention: WebSockets and Node.js - testing WS and SockJS by building a web app | dev.to | 2023-12-18

    SockJS is a library that mimics the native WebSockets API. Additionally, it will fall back to HTTP whenever a WebSocket fails to connect, or if the browser being used doesn’t support WebSockets. Like WS, SockJS requires a server counterpart; its maintainers provide both a JavaScript client library and a Node.js server library.

  • MQTT.js

    • Project mention: Server Sent Events simplified in SvelteKit | /r/sveltejs | 2023-06-25

  • 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.
