Question

我正在创建一个使用Monaco Editor的网络应用程序。因为已经加载了该代码，所以我决定也将Monaco用于静态代码块的语法突出显示。

基于this answer，我设法在静态代码块中添加了语法高亮显示（添加了元素和类名。

问题是，只有在创建Monaco编辑器实例（仅在另一页上发生）的情况下，才会加载相关的CSS。这意味着它仅在包含Monaco编辑器实例的页面时有效。

我使用以下React组件添加语法突出显示。

import { editor } from 'monaco-editor';
import React, { ReactElement, useEffect, useRef } from 'react';

interface CodeBlockProps {
  /**
   * The code to render.
   */
  code: string;

  /**
   * The language to use for highlighting the code.
   */
  language: string;
}

/**
 * Render a code block using syntax highlighting based on Monaco editor.
 */
export default function CodeBlock({ code, language }: CodeBlockProps): ReactElement {
  const ref = useRef<HTMLPreElement>();

  useEffect(() => {
    if (language) {
      editor.colorizeElement(ref.current, { theme: 'vs' });
    }
  }, [language]);

  return (
    <pre ref={ref} data-lang={language}>
      {code}
    </pre>
  );
}

如何使Monaco在不创建编辑器实例的情况下加载CSS？

受此问题报告的启发： https://github.com/microsoft/monaco-editor/issues/1828

我是这样做的：

import React from 'react';
import * as MonacoEditorApi from 'monaco-editor/esm/vs/editor/editor.api';
const { StaticServices } = require('monaco-editor/esm/vs/editor/standalone/browser/standaloneServices');
const { StandaloneThemeServiceImpl } = require('monaco-editor/esm/vs/editor/standalone/browser/standaloneThemeServiceImpl');

export const Viewer: React.FC<{ source: string }> = (props) => {
  // use a callback ref to get notified when the element has mounted
  const viewerRef = (ref: HTMLPreElement) => {
    if (ref) {
      MonacoEditorApi.editor.colorizeElement(ref, { theme: 'vs' });
      const themeService: typeof StandaloneThemeServiceImpl = StaticServices.standaloneThemeService.get();
      themeService.registerEditorContainer(ref);
    }
  };
  return (
    <pre data-lang="yaml" ref={viewerRef}>
      {props.source}
    </pre>
  );
};
