Siagent

A rewrite of a subset of Reagent's features, using Signaali for the reactivity.

This project was created to help people who want to use Re-signaali while they still have some Reagent components in their codebase. It might be suitable to you if you are in the process of migrating a large Reagent+Re-frame codebase toward another React wrapper, like UIx or Helix, or toward other libraries based on Signaali.

Project status

Siagent is currently experimental.

Treat it as a toy project unless it works for you 😄

Install

In your deps.edn:

{:fi.metosin/siagent {:mvn/version "..."}

Features:

• A drop-in replacement of Reagent covering the most commonly used parts of its API.
• Implementation easy to understand.
• Glitch-free reactivity provided by Signaali.
• No jumping caret issues in text fields.
• Can embed React components and be embedded into any existing React-based app (React, UIx, Helix, etc ...)
• Compatible with React 19 (the latest).
• Compatible with Re-frame 1.4.3 (the latest) via the Re-signaali fork.

Caveats:

• No special effort was made to make it behave exactly like Reagent.
• Does not cover all the Reagent legacy features:
  • No support for Reagent class components, only functions.
  • No support for Cursor, Track, Wrap.
  • No createRoot, use another React wrapper like in the test app.
• No effort was made on the performance side.

Parts the Reagent API covered

Everything which is tested in the test app is supported.

See:

• The hiccup section
• The Reagent section
• The interop section

Running the tests

npm test
