  • WatermelonDB

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

  • SurveyJS

    Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  • rxkit

    RxDB + SvelteKit

  • rasgueadb

    Indexing and querying layer for LMDB and flatbuffers

    I experimented with ObjectBox a bit, but I decided against using it because it isn't open source. The language wrappers are apache2 but the core library is only provided as a binary blob. I think this is bad because you can't inspect how it works, fix bugs, port it to new archs, integrate it fully into your build system, etc. Also, every cursor operation must call into their function entry points (as opposed to being inlined in your code for example).

    Instead, I've been working on my own library which also uses LMDB and flatbuffers. It's C++ only and still a WIP, but in case anyone else is interested, it's here: https://github.com/hoytech/rasgueadb

  • react-query

    Discontinued 🤖 Powerful asynchronous state management, server-state utilities and data fetching for TS/JS, React, Solid, Svelte and Vue. [Moved to: https://github.com/TanStack/query]

    I think modern solution is https://react-query.tanstack.com/

    Haven't tested it though yet.

  • RxDB

    A fast, local first, reactive Database for JavaScript Applications https://rxdb.info/

    RxDB maintainer here.

    I am aware of that problem. Pouchdb got some good love in the last weeks where some people made good PRs with fixes for the indexeddb adapter. But still it is mostly unmaintained and issues are just closed by the state bot instead of being fixed.

    So in the last major RxDB release [1] I abstracted the underlaying pouchdb in a way that it can be swapped out for a different storage engine. This means you could in theory use RxDB directly on SQLite or indexeddb. In practice of course someone has to first create a working implementation of the RxStorage interface.

  • holochain

    The current, performant & industrial strength version of Holochain on Rust.

    are running encrypted app code for them so that they can take part in the app/network, without having the required technical chops (the holofuel currency measures processing power). the FAQ does a good job of explaining it a bit more: https://holo.host/faq/

    i'm not super interested in the whole holo thing (they sold holofuel hosting credits). i am glad they did it because it meant the team could ramp up development.

    about the marx and engels thing. i am most excited about the potential for http://valueflo.ws on top of holochain [3], because it will allow us to move away from today's Enterprise Resource Planning (ERP) software, into a new paradigm of Network Resource Planning (ERP) software, that i hope will have a big impact on supply chains of the next economy (socialist).

  • syn

    Generalized Holochain DNA and UI library for building real-time shared state hApps (by holochain)

    hey so i messaged someone on the Holo team (Paul d'Aoust @helioscomm), this was his reply:

    Yes, people will want conflict-resolution for contention on scarce resources, and it'd be lovely to have that baked into the system. Two options (and yes, both still leave conflict resolution in the app dev's hands):

    - Have the zome function resolve the conflict after it retrieves conflicting metadata from the DHT

    - In the future we'll bake conflict resolution right into the network layer, so DHT authorities can resolve the conflict automatically using CRDTS or manually by pinging the nodes that published conflicting information so they can resolve it themselves.

    It's also worth mentioning Syn, a library which uses operational transforms (a precursor to CRDTs) for conflict-free collaborative document editing. https://github.com/holochain/syn I'm looking forward to seeing someone produce something similar, but with CRDTs.

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
