angular - npm 在多个环境上运行构建，没有提及指定的环境

Question

我正在使用具有多个环境的 Angular 项目。每当为单个环境进行构建需要很长时间时。我怎样才能减少它。我在这里添加了我的项目配置。

我使用的命令构建是“ npm run build -- --c demo ” & “ npm run build -- --c demo1 ”在单独的命令提示符下构建。每次构建大约需要 20 到 30 分钟。我们是否可以选择构建单个查询？

Answer 1

您可以一起执行命令，如下所示:

npm run build -- --c demo && npm run build -- --c demo1

或者，您可以使用包 json 脚本指定自己的命令:

{
  "name": "myApp",
  "version": "0.0.0",
  "engines": {
    "node": "10.13.0",
    "npm": "6.4.1"
  },
  "scripts": {
    "test": "jest src/app",
    "test:watch": "jest src/app --watch",
    "lint": "tslint -c tslint.json 'src/app/**/*.ts' --project src/tsconfig.json",
    "appStart": "npm run build -- --c demo && npm run build -- --c demo1" // This line
  },
}

然后简单地运行

npm run appStart

注:

有更多选项可以使用，用于一起执行多个命令，这里是 备忘单 :

A; B    # Run A and then B, regardless of success of A
A && B  # Run B if and only if A succeeded
A || B  # Run B if and only if A failed
A &     # Run A in background.
