This example shows the minimal entry point for a React application built with Parcel. The code imports the `App` component and CSS file, then uses `react-dom`'s `render` function to attach the app to the `#root` element in the HTML. It demonstrates the standard bootstrap pattern for a React project, where `index.js` serves as the initialization script, delegating all UI logic to the imported `App` component.

Parcel-react-jest - index.html

This example sets up a minimal React application that mounts a visualization into a root div, driven by the Parcel bundler and Jest for testing. It renders a single component using React’s `createRoot` API, with the page’s HTML containing only the mount point and a script tag for the bundled JavaScript. The visualization itself is not defined in the provided files, but the structure emphasizes a clean separation between the static markup, the React entry point, and the external bundle. The code demonstrates a standard modern toolchain setup rather than a specific graphical output.

Parcel-react-jest - index.css

This example demonstrates a minimal CSS styling setup for a React application built with Parcel and tested using Jest. The body text is rendered in blue through the `index.css` stylesheet, which is imported as part of the project’s bundling process. The visualization itself is not interactive or data-driven; instead, it serves as a static reference for how CSS rules are applied within the component hierarchy. Parcel handles the CSS import at build time, while Jest verifies the rendered output, making the example an instructional template for integrating styling into a modern JavaScript toolchain.

Parcel-react-jest - .babelrc

This example shows a minimal JavaScript configuration file, `.babelrc`, that defines the compilation settings for a React project. The configuration specifies two presets, `"env"` and `"react"`, which enable modern JavaScript syntax and JSX transformation within the build pipeline. The file demonstrates how Babel is used to compile source code, with the presets providing the necessary rules for the Parcel bundler and the Jest testing framework to process the code correctly. The entire visualization reduces to this small JSON structure, highlighting the simplicity of the setup.

Gist 0214c33084a385939fa02bb466c2a999

This example shows a React application that renders a basic component structure, confirming the presence of a title element through a unit test. The code uses Enzyme's `shallow` rendering to inspect the App component and Jest as the test runner, verifying that an `h1` tag exists. The test suite imports React and the App component, then asserts the rendered output includes the expected heading. No data visualization or interactive behavior is demonstrated; it focuses solely on component rendering validation within a Parcel and React setup.

React Starter

This example demonstrates a minimal React application that renders a single paragraph of text onto a blank HTML page. The page loads React 17 and ReactDOM via CDN, with the `index.html` file setting up the root `<div>` and the `index.js` script depending on the `react` and `react-dom` libraries. The code defines an `App` component that returns a `<div>` containing a `<p>` tag, then uses `ReactDOM.render()` to mount it into the `#root` element.

React Starter

This example renders a single-page React application that displays the text “Hello React!” centered on the page. It shows the minimal setup for a React project, using the `react` and `react-dom` libraries, with the `index.html` file loading the libraries from unpkg and the `bundle.js` file. The main `index.js` file imports React and ReactDOM, defines an `App` component, and calls `ReactDOM.render` to mount that component into the `#root` element.

Parcel-react-jest - setupTests.js

This example shows a minimal test setup for a React 16 project, configuring Enzyme to work with its adapter. It imports the `configure` function from the `enzyme` package and the `Adapter` class from `enzyme-adapter-react-16`, then calls `configure` with a new adapter instance. The code demonstrates the explicit initialization required to enable Enzyme’s testing utilities within a Jest environment, without displaying any test cases or rendering behavior.

React Starter Code

This example shows a minimal React application that renders the text “Hello React” inside a web page. The code imports the `react` and `react-dom` libraries and defines a simple `App` component that returns a `div` element. It then uses `ReactDOM.render` to mount this component into the `#root` div referenced in the HTML file. The HTML loads React and ReactDOM from unpkg CDN libraries, and the app’s behavior is limited to displaying the static greeting.
