import { useState } from 'react';
import Editor from 'md-editor-rt';
import 'md-editor-rt/lib/style.css';

export default function App() {
  const [text, setText] = useState('hello md-editor-rt！');

  return (
    <Editor
      modelValue={text}
      onChange={(modelValue) => {
        setText(modelValue);
      }}
    />
  );
}

Upload picture

Tips：When you paste and upload GIF，it will upload a static picture. So you should upload it by file system!

async onUploadImg(files: FileList, callback: (urls: string[]) => void) {
  const res = await Promise.all(
    Array.from(files).map((file) => {
      return new Promise((rev, rej) => {
        const form = new FormData();
        form.append('file', file);

        axios
          .post('/api/img/upload', form, {
            headers: {
              'Content-Type': 'multipart/form-data'
            }
          })
          .then((res) => rev(res))
          .catch((error) => rej(error));
      });
    })
  );

  callback(res.map((item: any) => item.data.url));
}
