package.json 版本说明

Using semantic versioning to specify update types your package can accept

dependency vs devDependencies

dependency 会被打包到生产环境中

npm install <package...>

yarn add react

devDependencies 只在开发阶段使用，不会打包到生产环境

npm install some_module --save-dev

yarn add <package...> [--dev/-D]

全局安装

npm install <package...> -g

yarn global add <package...>

package.json

// If you plan to publish your package, the most important things in your package.json are the name and version fields as they will be required

homepage
The url to the project homepage.

main
The main field is a module ID that is the primary entry point to your program.

{
  "name": "test-rp",
  "version": "1.0.0.1",
  "homepage": "https://github.com/owner/project#readme",
  "license" : "BSD-3-Clause",
  "main": "foo.js",
}

and 模块文件结构及 引用方式

当我们在前端页面引用时,是引用 es 文件夹里面的 某个模块还是 lib 文件夹下的模块？

import { Card } from "antd";

//使用import 默认就使用es 文件夹里面的模块

and 模块文件结构

+-- dist
+-- es
+-- lib
+-- package.json


package.json
{
  "main": "lib/index.js",
  "unpkg": "dist/antd.min.js",
  "module": "es/index.js",
}
