Preact.js-如何像React.js一样启动自动重新运行的服务器

Question

I would like to use a development server just like React does with npm start . But, with Preact when I use the same command it opens a static server and I have to restart it manually each time when I want to see some change in my project.

My package.json :

{
  "name": "yagoazedias-site",
  "version": "0.0.0",
  "description": "Ready-to-go Preact starter project powered by webpack.",
  "scripts": {
    "dev": "cross-env NODE_ENV=development webpack-dev-server --inline --hot --progress",
    "start": "serve build -s -c 1",
    "prestart": "npm run build",
    "build": "cross-env NODE_ENV=production webpack --progress",
    "prebuild": "mkdirp build && ncp src/assets build/assets",
    "test": "npm run -s lint && jest --coverage",
    "test:watch": "npm run -s test -- --watch",
    "lint": "eslint src test"
  },

Answer 1

Use the dev script instead?

$ npm run dev

Your start script is doing serve build -s -c 1 . React CRA's start script will boot up a webpack dev server which is what your dev script is doing.

npm start is short for npm run start . npm run <command> is just a small proxy that looks up the different commands you have listed in package.json .
