javascript - Preact.js - 如何像 React.js 一样启动自动重新运行服务器

Question

我想使用开发服务器，就像 React 使用 npm start 那样。但是，使用 Preact，当我使用相同的命令时，它会打开一个静态服务器，每次我想看到项目中的一些更改时，我都必须手动重新启动它。

我的package.json:

使用dev脚本代替？

$ npm run dev

您的start脚本正在做serve build -s -c 1 。 react CRA 的 start脚本将启动一个 webpack 开发服务器，这就是您的 dev脚本正在执行。

npm start是 npm run start 的缩写。 npm run <command>只是一个小型代理，用于查找您在 package.json 中列出的不同命令.
