Editor Markdown Editor share

Markdown Editor

In the react project, we need to use the Markdown editor. CodeMirror is the first one. It feels good to use, but it feels too big. I chose a lightweight React component that worked well and solved the problem, so I share it with you.

It has a lightweight preview editor, implemented using React. Js and TypeScript. This React component is designed to provide a simple Markdown editor with syntax highlighting support. This is based on textarea encapsulation, so it does not rely on any modern code editor such as Acs, CodeMirror, Monaco, etc

Advantage is

• Press Tab to indent or select text and drag to scale.
• It is based on textarea encapsulation and does not rely on any modern code editor.
• Not dependent on the author’s own encapsulationUIWComponent library.
• Automatically generate lists
