Installation

Signalis is available as two separate packages on npm:

@signalis/core - Core reactivity primitives
@signalis/react - React integration (includes core as a dependency)

Using npm

bash

# Install core only
npm install @signalis/core

# Or install React integration (includes core)
npm install @signalis/react

Using pnpm

bash

# Install core only
pnpm add @signalis/core

# Or install React integration (includes core)
pnpm add @signalis/react

Using yarn

bash

# Install core only
yarn add @signalis/core

# Or install React integration (includes core)
yarn add @signalis/react

Choosing a Package

Install `@signalis/core` if you:

Want to use Signalis with vanilla JavaScript/TypeScript
Are using a framework other than React
Need only the core reactivity primitives

Install `@signalis/react` if you:

Are building a React application
Want React-specific hooks (useSignal, useDerived, useSignalEffect)
Want the reactor HOC for automatic component re-rendering

Note: @signalis/react includes and re-exports all of @signalis/core, so you don't need to install both.

Version Compatibility

Node.js: 18.13.0 or higher
TypeScript: 5.0 or higher (if using TypeScript)
React: 19.0 or higher (for @signalis/react)
