This example demonstrates how a React component can use a ref callback to store a direct reference to a DOM node. The code defines an `Input` class component that assigns the underlying `<input>` element to `this.inputNode` through the `ref` attribute. This pattern enables imperative access to the input’s native methods and properties, such as focusing or reading its value, without relying on the React synthetic event system. The implementation uses React’s class component lifecycle and the standard `ref` callback API.

This example demonstrates how the React `useRef` hook preserves a mutable value across re-renders, unlike the `createRef` API, which creates a new ref each render. It visually compares the two by displaying the current render index alongside the persisted value from `useRef` and the reset value from `createRef` after a button click triggers a state update. The code uses `React.useState` to drive re-renders and `React.useRef` to hold a stable reference, while `createRef` shows its transient nature. The example also uses `useEffect` with a custom comparison to illustrate deep object dependency handling, referencing the React documentation.

React & D3 Starter

This example demonstrates a minimal pattern for combining React and D3.js, where React manages the component lifecycle and D3 performs direct DOM manipulation. The App component renders a single div element, and after the initial mount, the `useEffect` hook triggers a D3 selection. The `select()` function from D3 targets the DOM node referenced by React’s `useRef` hook, and the `.text()` method sets the div’s content to "Hello D3 & React." This shows how D3’s imperative API can be applied to a React-managed element.

This React example presents a minimal typing-race interface, displaying a header and a text input field. The application records the user’s keystrokes into the component’s state, updating the displayed text in real time. It uses React’s `React.Component`, the `event.target.value` property for input handling, and logs the current state to the console. The example demonstrates a basic two-way binding between a controlled input and the component’s state, showing the typed text as the user types.

Fork of React & D3 Starter

This example demonstrates how a React component can integrate D3 to render dynamic content, showing a simple text message that updates via D3’s selection API. The code uses `useRef` to attach a DOM node, then `select` from D3 to set its text content within a `useEffect` hook. It relies on React’s `createRoot` for mounting and D3’s `select` method for direct DOM manipulation. The example serves as a minimal starter template for combining React’s stateful rendering with D3’s data-driven utilities.

This example demonstrates a React component hierarchy that renders a list of reasons why React is enjoyable, using both a stateless functional component and a class-based wrapper. The class component supplies data via an array of strings, while the functional component maps over the array to produce list items. The code uses React’s `Component`, `PropTypes`, and `ReactDOM.render` to handle rendering, with lifecycle methods `componentWillMount` and `componentDidMount` logging console messages. The data is hardcoded within the class constructor rather than fetched externally.

React 101

This React 101 example demonstrates a hands-on teaching environment for the React library, showcasing functional components and props through a simple todo list. The header component (`Header.js`) dynamically changes its greeting and text color based on the current hour of the day, while the main list renders three todo items from a static `todosData` array. The app uses `ReactDOM.render()` to mount the root `App` component, which combines `Header`, `TodoItem`, and `Footer` components, with each `TodoItem` receiving its data via React props. Styling is applied through a linked CSS file, and the example leverages React 16.13.1 from unpkg.

This example shows a minimal integration of React and D3, displaying the text "Hello D3 & React" in a large, centered message. The code uses a `useRef` hook to attach a D3 selection to a div, then calls `select().text()` inside a `useEffect` to update the DOM. React 19 manages the component lifecycle, while D3 v7 handles the selection and text manipulation, demonstrating a simple pattern for combining the two libraries in a single page.

key bind

This example demonstrates a minimal React application that captures keyboard input. It renders an input field and logs a message to the console when the Enter key is pressed, using React’s `useState` and `onKeyPress` event handler. The code includes commented-out SVG elements and a `mousePosition` state, but only the input element is active. The app is built with React 16.9 and rendered via `ReactDOM.render` into the root div, with styling applied through an external stylesheet.
