webpack随记

1，package.json中script选项作用

{
  "name": "demo",
  "version": "1.0.0",
  "private": true,
  "scripts": {
    "start": "nuxt start",
    "generate--dev": "BASE_URL='https://dev.yygongzi.com' nuxt generate",
    "generate--demo": "BASE_URL='https://demo.yygongzi.com' nuxt generate",
    "generate": "BASE_URL='https://www.yygongzi.com' nuxt generate"
  },
  "dependencies": {
    "@nuxtjs/axios": "^5.4.1",
    "axios": "^0.19.0",
    "cross-env": "^5.2.0",
    "element-ui": "^2.4.11",
    "koa": "^2.6.2",
    "md5": "^2.2.1",
    "msgpack-lite": "^0.1.26",
    "nuxt": "^2.4.0"
  },
  "devDependencies": {
    "nodemon": "^1.18.9",
    "stylus": "^0.54.5",
    "stylus-loader": "^3.0.2"
  }
}

上述配置npm run generate会执行 BASE_URL='https://www.yygongzi.com' nuxt generate
npm run 如果不加任何参数，默认会列出package.json中所有可以执行的脚本命令。
npm 内置了两个命令 npm test ： npm run test; npm start：npm run start。
