Config

Use MdEditor.config(option: ConfigOption) to reconfigure renderer.

markedRenderer: (renderer: RewriteRenderer) => RewriteRenderer

Open target page in a new browser window:
```
MdEditor.config({
  markedRenderer(renderer) {
    renderer.link = (href, title, text) => {
      return `<a href="${href}" title="${title}" target="_blank">${text}</a>`;
    };

    return renderer;
  }
});
```
Reference: https://marked.js.org/using_pro#renderer, RewriteRenderer extends Renderer and rewrites heading, now provides index as the fifth parameter.
markedExtensions: Array<marked.TokenizerExtension & marked.RendererExtension>
```
import MdEditor from 'epn-markdown-editor';

MdEditor.config({
  markedExtensions: [your extension]
});
```
Reference: https://marked.js.org/using_pro#extensions
markedOptions: marked.MarkedOptions

Do not render <br> on a single line break:
```
import MdEditor from 'epn-markdown-editor';

MdEditor.config({
  markedOptions: { breaks: false }
});
```
Reference: https://marked.js.org/using_advanced#options

editorConfig: Add more languages, reset mermaid template or delay rendering time:

import MdEditor from 'epn-markdown-editor';

MdEditor.config({
  editorConfig: {
    languageUserDefined: { lang: StaticTextDefaultValue },
    mermaidTemplate: {
      flow: `flow tempalte`,
      ...more
    },
    // Default 500ms. It is set to 0ms when preview only and not set.
    renderDelay: 500
  }
});

editorExtensions: Config some dependency libraries, like highlight..

import MdEditor from 'epn-markdown-editor';

MdEditor.config({
  editorExtensions: { iconfont: 'https://xxx.cc' }
});

[EditorExtensions]

import MdEditor from 'epn-markdown-editor';

interface EditorExtensions {
  highlight?: {
    instance?: any;
    js?: string;
    css?: {
      [key: string]: {
        light: string;
        dark: string;
      };
    };
  };
  prettier?: {
    standaloneJs?: string;
    parserMarkdownJs?: string;
  };
  cropper?: {
    instance?: any;
    js?: string;
    css?: string;
  };
  iconfont?: string;
  screenfull?: {
    instance?: any;
    js?: string;
  };
  mermaid?: {
    instance?: any;
    js?: string;
  };
  katex?: {
    instance?: any;
    js?: string;
    css?: string;
  };

  const onUploadImg = async (files, callback) => {
    const res = await Promise.all(
      files.map((file) => {
        return new Promise((rev, rej) => {
          const form = new FormData();
          form.append('file', file);

          axios
            .post('/api/img/upload', form, {
