  • just

    A library of dependency-free JavaScript utilities that do just one thing. (by angus-c)

    Project mention: TC39: Add Object.groupBy and Map.groupBy | | 2023-12-19

    You can roll your own or use a utility library. A simple zero-dependency library would be something like just-group-by [1]. Although I now prefer remeda [2] as it seems to have the best typescript support, especially the strict variants such as `grouBy.strict`.


  • pannellum

    Pannellum is a lightweight, free, and open source panorama viewer for the web.

    Project mention: free virtual tour software | /r/360Cameras | 2023-05-23

    Unity tour template should probably cover a 6 (I haven't used it yet, it's on my projects que to test out). I also have Pannellum qued, but since I haven't developed with it yet I don't know how easy it is to work with. I built my own tour using the insideout shader, but it had major glitches, so I don't recommend making it from scratch unless you're already good at software dev and have time to troubleshoot.

  • stdlib

    ✨ Standard library for JavaScript and Node.js. ✨

    Project mention: Node still seems better than python after all this time for web server speed but.. | /r/node | 2023-06-20

    Numpy is a library - node.js has plenty of them, what is missing? There is stdlib package that offers optimized math functions, for example.

  • lwc

    ⚡️ LWC - A Blazing Fast, Enterprise-Grade Web Components Foundation

    Project mention: | /r/SalesforceDeveloper | 2023-07-11

    Actually I was wondering if lwc oss is still a thing. The website looks like it hasn't been updated since the release in 2019. Are many people using it or was it a nice try by Salesforce but can we consider it dead? I know of course it can't compete with react, vue or angular, but has it built a nice user base around it to keep it interesting?
