前端-选中DOM定位源代码

用到的工具：react-dev-inspector

使用流程

根据react-dev-inspector文档进行配置

安装

yarn add --dev react-dev-inspector

import { createRoot } from 'react-dom/client'
import { Inspector } from 'react-dev-inspector'
import { App } from './App'
import './index.css'
 
createRoot(document.getElementById('root') as HTMLDivElement)
  .render(
    <React.StrictMode>
      <Inspector />
      <App />
    </React.StrictMode>,
  )

3. 我的工程是由create-react-app创建的，所以参考这部分文档，根据文档提示我需要先去安装customize-cra

4. 根据customize-cra文档进行配置
4.1 安装

npm i customize-cra react-app-rewired --dev

4.2 配置：新建config-overrides.js文件，需要与package.json文件同级

const {
  override,
  addDecoratorsLegacy,
  disableEsLint,
  addBundleVisualizer,
  addWebpackAlias,
  adjustWorkbox
} = require("customize-cra");
const path = require("path");

module.exports = override(
  // enable legacy decorators babel plugin
  addDecoratorsLegacy(),

  // disable eslint in webpack
  disableEsLint(),

  // add webpack bundle visualizer if BUNDLE_VISUALIZE flag is enabled
  process.env.BUNDLE_VISUALIZE == 1 && addBundleVisualizer(),

  // add an alias for "ag-grid-react" imports
  addWebpackAlias({
    ["ag-grid-react$"]: path.resolve(__dirname, "src/shared/agGridWrapper.js")
  }),

  // adjust the underlying workbox
  adjustWorkbox(wb =>
    Object.assign(wb, {
      skipWaiting: true,
      exclude: (wb.exclude || []).concat("index.html")
    })
  )
);

回到react-dev-inspector文档，我们还需要安装配置一个中间件

5.1 安装

yarn add --dev @react-dev-inspector/middleware

5.2 配置：我们修改下4.2步中配置的config-overrides.js文件

const {
    override,
    overrideDevServer,
    addDecoratorsLegacy,
    disableEsLint,
    addBundleVisualizer,
    addWebpackAlias,
    adjustWorkbox,
  } = require("customize-cra");
  const { launchEditorMiddleware } = require('@react-dev-inspector/middleware')
  const path = require("path");
  

  const webapckOverride = override(
    // enable legacy decorators babel plugin
    addDecoratorsLegacy(),
  
    // disable eslint in webpack
    disableEsLint(),
  
    // add webpack bundle visualizer if BUNDLE_VISUALIZE flag is enabled
    process.env.BUNDLE_VISUALIZE == 1 && addBundleVisualizer(),
  
    // add an alias for "ag-grid-react" imports
    addWebpackAlias({
      ["ag-grid-react$"]: path.resolve(__dirname, "src/shared/agGridWrapper.js")
    }),

    // adjust the underlying workbox
    adjustWorkbox(wb =>
      Object.assign(wb, {
        skipWaiting: true,
        exclude: (wb.exclude || []).concat("index.html")
      })
    )
  );

  module.exports = {
    /**
     * react-dev-inspector server config for webpack-dev-server
     */
    devServer: overrideDevServer(
      serverConfig => {
        // https://webpack.js.org/configuration/dev-server/#devserversetupmiddlewares
        serverConfig.setupMiddlewares = (middlewares) => {
          middlewares.unshift(launchEditorMiddleware)
          return middlewares
        }
   
        return serverConfig
      },
    ),
   
    webpack: webapckOverride
  }

来到页面，按下快捷键 ctrl⌃ + shift⇧ + commmand⌘ + c（松开）；鼠标移动到某个元素，并点击；就能看到编辑器打开了对应页面，且光标在该元素的位置
如果编辑器报错：The editor process exited with an error: spawn code ENOENT，可以参考从命令行启动

7.1在VS Code面板输入Cmd+Shift+P
7.2安装Shell command: Install 'code' command in PATH
