What is @uiw/react-codemirror?

@uiw/react-codemirror is a React component for CodeMirror, a versatile text editor implemented in JavaScript for the browser. It provides a flexible and customizable code editor with support for various programming languages, themes, and extensions.

What are @uiw/react-codemirror's main functionalities?

Basic Usage

This code demonstrates the basic usage of @uiw/react-codemirror. It imports the necessary modules and sets up a simple CodeMirror editor with JavaScript syntax highlighting.

import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';

const App = () => {
  return (
    <CodeMirror
      value="console.log('Hello, world!');"
      height="200px"
      extensions={[javascript()]}
    />
  );
};

export default App;

Theming

This example shows how to apply a theme to the CodeMirror editor. The 'oneDark' theme is imported and added to the extensions array.

import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';
import { oneDark } from '@codemirror/theme-one-dark';

const App = () => {
  return (
    <CodeMirror
      value="console.log('Hello, world!');"
      height="200px"
      extensions={[javascript(), oneDark]}
    />
  );
};

export default App;

Handling Events

This code demonstrates how to handle change events in the CodeMirror editor. The 'handleChange' function logs the new value to the console whenever the content changes.

import React from 'react';
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';

const App = () => {
  const handleChange = (value, viewUpdate) => {
    console.log('Value changed:', value);
  };

  return (
    <CodeMirror
      value="console.log('Hello, world!');"
      height="200px"
      extensions={[javascript()]}
      onChange={handleChange}
    />
  );
};

export default App;
