🚀 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()
}
