javascript - 将 monaco-editor 和 monaco-languageclient 包装为 react 组件时，对 'vscode' 的奇怪的未解决依赖项

我需要创建一个集成了 Microsoft 的 Monaco 编辑器和 TypeFox 的 monaco-languageclient 的 React 组件。目标是让该组件能够通过语言服务器协议(protocol)与语言服务器进行通信。

import React, { useEffect, useRef, useState } from 'react'
import * as monaco from 'monaco-editor/esm/vs/editor/editor.api';
import _ from 'lodash'


import { listen } from 'vscode-ws-jsonrpc';
import {
  CloseAction,
  createConnection,
  ErrorAction,
  MonacoLanguageClient,
  MonacoServices
} from 'monaco-languageclient';


import normalizeUrl from 'normalize-url';
import ReconnectingWebSocket from 'reconnecting-websocket';

function createLanguageClient(connection) {
  return new MonacoLanguageClient({
    name: "Sample Language Client",
    clientOptions: {
      // use a language id as a document selector
      documentSelector: [ 'json' ],
      // disable the default error handler
      errorHandler: {
        error: () => ErrorAction.Continue,
        closed: () => CloseAction.DoNotRestart
      }
    },
    // create a language client connection from the JSON RPC connection on demand
    connectionProvider: {
      get: (errorHandler, closeHandler) => {
        return Promise.resolve(createConnection(connection, errorHandler, closeHandler))
      }
    }
  });
}

function createUrl(path) {
  // const protocol = 'ws';

  return normalizeUrl("ws://localhost:3000/sampleServer")

  // return normalizeUrl(`${protocol}://${location.host}${location.pathname}${path}`);
}

function createWebSocket(url) {
  const socketOptions = {
    maxReconnectionDelay: 10000,
    minReconnectionDelay: 1000,
    reconnectionDelayGrowFactor: 1.3,
    connectionTimeout: 10000,
    maxRetries: Infinity,
    debug: false
  };
  return new ReconnectingWebSocket(url, undefined, socketOptions);
}


const ReactMonacoEditor = ({ initialText, ...props }) => {
  let localRef = useRef(null)

  const [ value, setValue ] = useState(initialText)

  useEffect(() => {
    monaco.languages.register({
      id: 'json',
      extensions: [ '.json', '.bowerrc', '.jshintrc', '.jscsrc', '.eslintrc', '.babelrc' ],
      aliases: [ 'JSON', 'json' ],
      mimetypes: [ 'application/json' ],
    });

    const model = monaco.editor.createModel(value, 'json', monaco.Uri.parse('inmemory://model.json'))
    const editor = monaco.editor.create(localRef.current, {
      model,
      glyphMargin: true,
      lightbulb: {
        enabled: true
      }
    });

    editor.onDidChangeModelContent(_.debounce(e => {
      setValue(editor.getValue())
    }, 100))

    MonacoServices.install(editor);

    // create the web socket
    const url = createUrl('/sampleSer ver')
    const webSocket = createWebSocket(url);

// listen when the web socket is opened
    listen({
      webSocket,
      onConnection: connection => {
        // create and start the language client
        const languageClient = createLanguageClient(connection);
        const disposable = languageClient.start();
        connection.onClose(() => disposable.dispose());
      }
    });

    return () => editor.dispose()
  }, [])

  return (
    <div ref={localRef} style={{ width: 800, height: 600 }}/>
  )
}

export default ReactMonacoEditor

包.json

      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我期待组件呈现。相反，我得到

Failed to compile.

./node_modules/vscode-base-languageclient/lib/workspaceFolders.js
Module not found: Can't resolve 'vscode' in '.../node_modules/vscode-base-languageclient/lib'
Waiting for the debugger to disconnect...

不知道如何继续。

最佳答案

几个小时以来，我一直在为同样的问题苦苦挣扎。最终我在 changelog of the monaco-languageclient 中发现了以下评论:



将该别名添加到我的 webpack 配置(在我的情况下为 quasar.conf)后，编译成功。

因此，事实上 monaco-languageclient 并不像错误消息所暗示的那样依赖于 vscode 模块，而是应该使用包本身内部的兼容性 stub 。
