react MonacoEditor react-monaco-editor的使用编辑功能很强大，react MonacoEditor包含断点、代码提示，自定义黑色背景，功能齐全。可以直接使用

1、css样式

.breakpoints {
    background: red;
    width: 10px !important;
    height: 10px !important;
    left: 0px !important;
    top: 3px;
    border-radius: 5px;
}

.breakpoints-fake {
    background: red;
    width: 10px !important;
    height: 10px !important;
    left: 0px !important;
    top: 3px;
    border-radius: 5px;
}

2、直接上我封装好了的组件、拿去不用谢。

import React from 'react';
import MonacoEditor from 'react-monaco-editor';
import style from "./index.css"

export default class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      code: "test",
    }
    this.editor = null;
    this.monaco = null;
    this.decorations = [];
    this.onChange = this.onChange.bind(this);
    this.editorDidMount = this.editorDidMount.bind(this);
  }

  editorDidMount(editor, monaco) {
    if (!this.editor) this.editor = editor, this.monaco = monaco, this.editorMousDown(), this.onMouseMove();
    editor.focus();
  }

  onChange(newValue, e) {
    this.props.parent(this.props.data._id, newValue);
  }

  onMouseMove() {
    this.editor.onMouseMove(e => {
      if (!this.isJsEditor()) return
      this.removeFakeBreakPoint()
      if (e.target.detail && e.target.detail.offsetX && e.target.detail.offsetX >= 0 && e.target.detail.offsetX <= 10) {
        let line = e.target.position.lineNumber
        this.addFakeBreakPoint(line)
      }
    })
    this.editor.onMouseLeave(() => {
      this.removeFakeBreakPoint()
    })
    this.editor.onKeyDown(e => {
      if (e.code === 'Enter') {
        this.removeFakeBreakPoint()
      }
    })
  }

  trigger(id) {
    if (!this.editor) return
    this.editor.trigger('anyString', id)
  }

  insertContent(text) {
    if (this.editor) {
      let selection = this.editor.getSelection()
      let range = new this.monaco.Range(selection.startLineNumber, selection.startColumn, selection.endLineNumber, selection.endColumn)
      let id = {
        major: 1,
        minor: 1
      }
      let op = {
        identifier: id,
        range: range,
        text: text,
        forceMoveMarkers: true
      }
      this.editor.executeEdits(this.root, [op])
      this.editor.focus()
    }
  }

  editorMousDown() {
    this.editor.onMouseDown(e => {
      if (!this.isJsEditor()) return
      if (e.target.detail && e.target.detail.offsetX && e.target.detail.offsetX >= 0 && e.target.detail.offsetX <= 10) {
        let line = e.target.position.lineNumber
        if (this.editor.getModel().getLineContent(line).trim() === '') {
          return
        }
        if (!this.hasBreakPoint(line)) {
          this.addBreakPoint(line)
        } else {
          this.removeBreakPoint(line)
        }
        if (this.lastPosition) {
          this.editor.setPosition(this.lastPosition)
        } else {
          document.activeElement.blur()
        }
      }
      if (e.target.type === 6 || e.target.type === 7) {
        this.lastPosition = this.editor.getPosition()
      }
    })
  }

  isJsEditor() {
    return this.editor.getModel().getLanguageIdentifier().language === 'javascript'
  }

  addFakeBreakPoint(line) {
    if (this.hasBreakPoint(line)) return;
    let value = {
      range: new this.monaco.Range(line, 1, line, 1),
      options: {
        isWholeLine: true,
        linesDecorationsClassName: 'breakpoints-fake'
      }
    }
    this.decorations = this.editor.deltaDecorations(this.decorations, [value])
  }

  removeFakeBreakPoint() {
    this.decorations = this.editor.deltaDecorations(this.decorations, [])
  }

  async addBreakPoint(line) {
    let model = this.editor.getModel()
    if (!model) return
    let value = {
      range: new this.monaco.Range(line, 1, line, 1),
      options: {
        isWholeLine: true,
        linesDecorationsClassName: 'breakpoints'
      }
    }
    model.deltaDecorations([], [value])
  }

  async removeBreakPoint(line) {
    let model = this.editor.getModel()
    if (!model) return
    let decorations
    let ids = []
    if (line !== undefined) {
      decorations = this.editor.getLineDecorations(line)
    } else {
      decorations = this.editor.getAllDecorations()
    }
    for (let decoration of decorations) {
      if (decoration.options.linesDecorationsClassName === 'breakpoints') {
        ids.push(decoration.id)
      }
    }
    if (ids && ids.length) {
      model.deltaDecorations(ids, [])
    }
  }

  hasBreakPoint(line) {
    let decorations = this.editor.getLineDecorations(line)
    for (let decoration of decorations) {
      if (decoration.options.linesDecorationsClassName === 'breakpoints') {
        return true
      }
    }
    return false
  }

  render() {
    const code = this.state.code;
    const options = {
      selectOnLineNumbers: true
    };
    return (
      
    );
  }
}

3、使用直接引入到别的组件中即可使用
