Nodejs工具推荐:babel-watch,比nodemon快好多
babel-watch only starts babel in the "master" process where it also starts the file watcher. The transpilation is performed in that process too. On file-watcher events, it spawns a pure node process and passes transpiled code from the parent process together with the source maps. This allows us to avoid loading babel and all its deps every time we restart the JS script/app.
关于Node.js工具babel-watch的推荐,确实对于许多开发者来说,它是一个比nodemon更高效的选择,尤其适用于那些依赖Babel进行代码转译的项目。以下是对babel-watch的详细解析:
babel-watch优势
babel-watch是一个Babel命令行接口(CLI)扩展,它监视源文件的变化并自动重新运行Babel编译,无需手动刷新或重启应用。相较于nodemon,babel-watch在处理JavaScript源文件变化时更加高效,因为它只编译改动过的模块,减少了不必要的等待时间。
使用示例
- 安装babel-watch:
npm install --save-dev babel-watch @babel/core @babel/preset-env
- 配置Babel(如尚未配置):
创建.babelrc
文件:
{
"presets": ["@babel/preset-env"]
}
- 修改package.json:
"scripts": {
"watch": "babel-watch src --out-dir dist --extensions '.js,.jsx'"
}
- 运行babel-watch:
npm run watch
现在,每当你的源代码发生变化时,Babel就会自动重新编译它们到指定的输出目录。
babel-watch是前端开发者提高工作效率的利器,它融合了实时编译和智能监控的功能,使得开发过程更加流畅。
