Our great sponsors
  • SurveyJS - Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App
  • WorkOS - The modern identity platform for B2B SaaS
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • reactively

    Reactivity libraries are at the heart of modern web component frameworks like Solid, Qwik, Vue, and Svelte. And in some cases you can add fine-grained reactive state management to other libraries like Lit and React. Reactively comes with a decorator for adding reactive properties to any class, as well as prototype integration with Lit. Preact Signals comes with a prototype integration with React. Expect more integrations as these reactivity cores mature.

  • React

    The library for web and native user interfaces.

  • 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.

  • signals

    Manage state with style in every framework

  • usignal

    A blend of @preact/signals-core and solid-js basic reactivity API

    Fine-grained reactivity libraries have been growing in popularity recently. Examples include new libraries like Preact Signals, µsignal, and now Reactively, as well as longer-standing libraries like Solid, S.js, and CellX. Using these libraries, programmers can make individual variables and functions reactive. Reactive functions run automatically, and re-run 'in reaction' to changes in their sources.

  • S

    S.js - Simple, Clean, Fast Reactive Programming in Javascript (by adamhaile)

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • flimsy

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

    An implementation of this might look like the following (code by Fabio Spampinato):

  • solid

    A declarative, efficient, and flexible JavaScript library for building user interfaces.

    Current reactivity benchmarks (Solid, CellX, Maverick) are focused on creation time, and update time for a static graph. Additionally, existing benchmarks aren't very configurable, and don't test for dynamic dependencies.
