Top 17 reactivity Open-Source Projects

  • signals

    Manage state with style in every framework

    • Project mention: Svelte 5: Runes | news.ycombinator.com | 2023-09-20

    Putting the runic terminology aside and looking into how the signal primitive is implemented should dispel the magic. I learned a lot from examining preact's implementation: https://github.com/preactjs/signals/blob/main/packages/core/...

  • ipyflow

    A reactive Python kernel for Jupyter notebooks.

    • Project mention: Show HN: Marimo – an open-source reactive notebook for Python | news.ycombinator.com | 2024-01-12

    You're probably referring to nbgather (https://github.com/microsoft/gather), which shipped with VSCode for a while.

    nbgather used static slicing to get all the code necessary to reconstruct some cell. I actually worked with Andrew Head (original nbgather author) and Shreya Shankar to implement something similar in ipyflow (but with dynamic slicing and a not-as-nice interface): https://github.com/ipyflow/ipyflow?tab=readme-ov-file#state-...

    I have no doubt something like this will make its way into marimo's roadmap at some point :)

  • 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.

  • reatom

    Reatom - the ultimate state manager

    • Project mention: Is redux and thunks still used or are there other alternatives for it now? | /r/reactjs | 2023-05-10

    Nanostores and Reatom are also great, fast atomic libs

  • signals

    A tiny (~1kB minzipped) and extremely fast library for creating reactive observables via functions. (by maverick-js)

  • mam_mol

    $mol - fastest reactive micro-modular compact flexible lazy ui web framework.

    • Project mention: $mol – fastest reactive micro-modular compact flexible lazy UI web framework | news.ycombinator.com | 2024-03-13

  • cami.js

    Cami.js is a simple yet powerful toolkit for interactive islands in web applications. No build step required.

    • Project mention: HTML Web Components | news.ycombinator.com | 2023-11-13

    Preact requires a build step otherwise you don't get JSX and you have to build applications a la mithril.js mode:

    > const app = h('h1', null, 'Hello World!');

    With Web Components no build step is required and you're still able to build JSX'ish code. See the code below this section: https://github.com/kennyfrc/cami.js#key-concepts--api

  • flimsy

    A single-file <1kb min+gzip simplified implementation of the reactive core of Solid, optimized for clean code.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • signaldb

    SignalDB is a local JavaScript database with a MongoDB-like interface and TypeScript support, enabling optimistic UI with signal-based reactivity across multiple frameworks. It integrates easily with libraries like Angular, Solid.js, Preact, and Vue, simplifying data management with schema-less design, in-memory storage, and fast queries.

    • Project mention: Show HN: SignalDB – Reactive Local JavaScript Database | news.ycombinator.com | 2023-10-20

  • Cample.js

    One of the fastest frameworks without a virtual DOM on the Internet!

    • Project mention: Show HN: Cample.js – Framework Without VDOM | news.ycombinator.com | 2023-10-15

  • bagel

    A reactive and strongly-typed, but also pragmatic, new programming language. Compiles to JavaScript, designed to be comfy for people used to the JavaScript/TypeScript language and ecosystem.

  • flex
