  1. WatermelonDB

    🍉 Reactive & asynchronous database for powerful React and React Native apps ⚡️

    Project mention: Hacktoberfest! - Week 2 | dev.to | 2024-10-18

    This app used WatermelonDB as its database, which I also hadn't heard of before. From their documentation, I quickly learned how to add an index to the schema. However, I also learned that they didn't support adding an index for migration. In fact, they were asking for contribution.

    Project mention: Asyncapi Specification | news.ycombinator.com | 2024-10-30

  4. van

    🍦 VanJS: World's smallest reactive UI framework. Incredibly Powerful, Insanely Small - Everyone can build a useful UI app in an hour.

    Project mention: Vanillajsx.com | news.ycombinator.com | 2024-08-16

    VanJS deserves a mention here! https://vanjs.org/

    Another interesting thing is that other JSX libraries like Solid.JS also return DOM nodes, and I love that this idea is gaining traction

    The closer we get to the platform we're using, the better. Being removed by layers of abstractions CAN be useful, but in practice, I haven't found a use for abstracting away the platform. (yet.)

    Maybe huge projects like Facebook benefit from this tho (which I haven't worked on)
