{"library":"react-component-managers","title":"React Component Managers","description":"react-component-managers is a utility library designed to simplify the composition of functionality into React components, serving as an alternative to traditional mixins. Released in 2018, its stable version is `3.2.2`. The library aims to provide a lightweight composition solution, similar to `recompose` but without introducing Higher-Order Component (HoC) wrappers, which can lead to deeper component hierarchies. Its primary use case was to address concerns around mixin deprecation and the overhead of HoCs, offering a direct way to inject behavior. Given its last update in July 2018, prior to the widespread adoption of React Hooks, the library is no longer actively developed and reflects a component design paradigm that has largely been superseded by modern React patterns. Its release cadence was slow, and development has ceased.","language":"javascript","status":"abandoned","last_verified":"Sun Apr 19","install":{"commands":["npm install react-component-managers"],"cli":null},"imports":["import { manager } from 'react-component-managers'","import { compose } from 'react-component-managers'","import * as ComponentManagers from 'react-component-managers'"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"import React from 'react';\nimport { manager, compose } from 'react-component-managers';\n\nconst counter = manager((_props, { on }) => {\n  let count = 0;\n  return on('click', () => count++);\n});\n\nconst logger = manager((_props, { on }) => {\n  on('mount', () => console.log('Component mounted!'));\n  on('unmount', () => console.log('Component unmounted!'));\n});\n\nclass MyComponent extends React.Component {\n  render() {\n    return (\n      <div>\n        <h1>Count: {this.state.count}</h1>\n        <button onClick={this.props.onClick}>Increment</button>\n      </div>\n    );\n  }\n}\n\n// Compose the managers with the component\nconst ManagedComponent = compose(counter, logger)(MyComponent);\n\n// Example usage (e.g., in App.js)\n// function App() {\n//   return <ManagedComponent />;\n// }\n// export default App;\n\n// For quickstart, just render to demonstrate the pattern\n// This isn't a full runnable example without a React renderer\n// but illustrates the composition.\n","lang":"javascript","description":"Demonstrates the composition of two managers, `counter` and `logger`, into a class component `MyComponent` using the `compose` helper.
