    React Codemirror

    React Codemirror

    Codemirror Component for React.js

    React Codemirror is a React component wrapper around the CodeMirror code editor, making it easy to embed a powerful text editor into React applications. It exposes CodeMirror through a declarative React interface, where editor value and options are passed in as props and changes are reported via callbacks. The component can be integrated either through npm, as part of a bundler-based build process, or via a standalone UMD build included directly in a web page. It supports initialization with an initial code value and allows you to control options like line numbers, language mode, and other CodeMirror settings. Developers can access the underlying CodeMirror instance using a ref and the getCodeMirror method, enabling them to call any API that the base editor provides. The package supports a variety of event callbacks, including change, cursor activity, focus changes, and scroll events, making it suitable for building fully interactive editing experiences.
