@types/react-reconciler

What is @types/react-reconciler?

@types/react-reconciler provides TypeScript definitions for the react-reconciler package, which is a low-level API for creating custom renderers in React. This package allows developers to build custom renderers that can manage how React components are rendered and updated in different environments.

What are @types/react-reconciler's main functionalities?

Creating a Custom Renderer

This code demonstrates how to create a custom renderer using the react-reconciler package. The hostConfig object defines how the renderer should handle various operations like creating instances, appending children, and committing updates.

const Reconciler = require('react-reconciler');
const hostConfig = {
  now: Date.now,
  getRootHostContext: () => ({}),
  getChildHostContext: () => ({}),
  prepareForCommit: () => {},
  resetAfterCommit: () => {},
  createInstance: (type, props) => ({ type, props }),
  appendInitialChild: (parent, child) => { parent.children = parent.children || []; parent.children.push(child); },
  finalizeInitialChildren: () => {},
  prepareUpdate: () => true,
  shouldSetTextContent: () => false,
  createTextInstance: text => text,
  commitUpdate: (instance, updatePayload, type, oldProps, newProps) => { instance.props = newProps; },
  commitTextUpdate: (textInstance, oldText, newText) => { textInstance = newText; },
  removeChild: (parentInstance, child) => { parentInstance.children = parentInstance.children.filter(c => c !== child); }
};
const MyRenderer = Reconciler(hostConfig);
const container = MyRenderer.createContainer({}, false, false);
MyRenderer.updateContainer(<div>Hello, world!</div>, container, null, () => {});

Updating a Custom Renderer

This code demonstrates how to update the custom renderer created in the previous example. The update function changes the content of the container to a new React element.

const update = () => {
  MyRenderer.updateContainer(<div>Hello, React!</div>, container, null, () => {});
};
update();

Other packages similar to @types/react-reconciler

react-dom

react-dom is the standard renderer for React applications targeting the web. It provides the necessary APIs to render React components to the DOM. Unlike @types/react-reconciler, which is used for creating custom renderers, react-dom is specifically designed for web applications.

react-native

react-native is a framework for building native applications using React. It provides a renderer that targets mobile platforms like iOS and Android. While @types/react-reconciler allows for custom renderers, react-native is a specialized renderer for mobile development.

react-three-fiber

react-three-fiber is a renderer for React that targets three.js, a 3D graphics library. It allows developers to build 3D scenes using React components. This package is similar to @types/react-reconciler in that it provides a custom rendering environment, but it is specifically designed for 3D graphics.
