🚀 高效开发技巧

多光标编辑技巧

1. 批量编辑相同内容

javascript
// 选中一个变量名,按 Ctrl+D (Cmd+D) 逐个选择相同内容
const userName = 'john'
const userAge = 25
const userEmail = 'john@example.com'

// 使用 Ctrl+Shift+L (Cmd+Shift+L) 选择所有相同内容
// 可以同时修改所有 user 变量名

2. 列编辑模式

javascript
// 按住 Alt (Option) 键拖拽鼠标,可以进行列选择
const data = [
  { name: 'Alice',   age: 25 },
  { name: 'Bob',     age: 30 },
  { name: 'Charlie', age: 35 }
]
// 可以同时编辑多行的相同位置

代码片段和模板

1. 自定义代码片段

json
// 在用户代码片段中添加 (Ctrl+Shift+P -> "Configure User Snippets")
{
  "Vue 3 Composition API": {
    "prefix": "v3setup",
    "body": [
      "<template>",
      "  <div class=\"$1\">",
      "    $2",
      "  </div>",
      "</template>",
      "",
      "<script setup lang=\"ts\">",
      "import { ref, reactive, computed, onMounted } from 'vue'",
      "",
      "$3",
      "</script>",
      "",
      "<style scoped>",
      ".$1 {",
      "  $4",
      "}",
      "</style>"
    ],
    "description": "Vue 3 Composition API 组件模板"
  }
}

2. React 函数组件片段

json
{
  "React Function Component": {
    "prefix": "rfc",
    "body": [
      "import React from 'react'",
      "",
      "interface ${1:ComponentName}Props {",
      "  $2",
      "}",
      "",
      "const ${1:ComponentName}: React.FC<${1:ComponentName}Props> = ({ $3 }) => {",
      "  return (",
      "    <div className=\"${4:component-name}\">",
      "      $5",
      "    </div>",
      "  )",
      "}",
      "",
      "export default ${1:ComponentName}"
    ],
    "description": "React 函数组件模板"
  }
}

智能搜索技巧

1. 文件搜索技巧

bash
# 快速打开文件 (Ctrl+P / Cmd+P)
# 支持模糊搜索和路径搜索

# 搜索文件名
component.vue

# 搜索路径
src/components/

# 组合搜索
src comp vue

# 使用 @ 符号搜索文件内的符号
@function
@class
@interface

2. 全局搜索技巧

bash
# 正则表达式搜索 (启用正则表达式模式)
function\s+\w+\(.*\)\s*{

# 排除文件类型
*.min.js
node_modules/

# 包含特定文件类型
*.vue,*.js,*.ts

# 搜索特定目录
./src/components/

调试技巧

1. 断点调试

javascript
// 条件断点:右键行号设置条件
if (user.id === 123) {
  // 只在特定条件下触发断点
  debugger
}

// 日志断点:不中断执行,只输出日志
console.log('User ID:', user.id)

2. 调试配置

json
// .vscode/launch.json
{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Vue App",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:3000",
      "webRoot": "${workspaceFolder}/src",
      "sourceMapPathOverrides": {
        "webpack:///src/*": "${webRoot}/*"
      }
    }
  ]
}

重构技巧

1. 智能重命名

javascript
// 选中变量/函数名,按 F2 进行智能重命名
// 会自动重命名所有引用位置
function calculateUserAge(birthDate) {
  // F2 重命名 calculateUserAge 会同时更新所有调用位置
  return new Date().getFullYear() - birthDate.getFullYear()
}

2. 提取函数/变量

javascript
// 选中代码块,按 Ctrl+. (Cmd+.) 选择重构选项
const result = data.filter(item => item.active)
                  .map(item => item.name)
                  .sort()

// 可以提取为独立函数
function getActiveUserNames(data) {
  return data.filter(item => item.active)
             .map(item => item.name)
             .sort()
}

  "search.useIgnoreFiles": true,
  "search.useGlobalIgnoreFiles": true,
  "search.followSymlinks": false,
  "search.smartCase": true
}

3. 插件管理

  • 定期清理不使用的插件
  • 使用工作区推荐插件功能
  • 避免安装功能重复的插件

🔧 故障排除

常见问题解决

1. TypeScript 服务重启

Ctrl+Shift+P -> TypeScript: Restart TS Server

2. 插件冲突排查

Ctrl+Shift+P -> Developer: Reload Window

3. 设置同步问题

bash
# 重置本地设置同步
Settings Sync: Reset Local

📋 最佳实践

1. 团队协作

  • 使用工作区配置文件统一团队设置
  • .vscode/extensions.json 中推荐必要插件
  • 建立代码格式化和检查规范
  • 使用 .editorconfig 统一编辑器配置

2. 项目组织

  • 合理使用工作区功能管理多项目
  • 配置项目特定的调试和任务
  • 使用代码片段提升开发效率
  • 建立项目模板和脚手架

3. 开发效率

  • 熟练掌握快捷键操作
  • 善用多光标编辑功能
  • 利用智能搜索和导航
  • 配置合适的代码片段

4. 代码质量
