A Simple CodeMirror and Remark Markdown Editor

Here is a simple CodeMirror 6 and Remark Markdown Editor, with syntax highlighting and a live preview, written in React, on CodeSandbox.

It uses React hooks, with useDebounce to make it so it only updates every few hundred milliseconds, and with a useImperativeHandle hook so it can provide its own interface to get the text from CodeMirror.

The CodeEditor and MarkdownView components are simplified versions of what we're using in the new web app we're building.
