创建好上面的 package.json 文件

执行 npm i 安装好依赖

sdk.config.js

import ts from 'rollup-plugin-typescript2'
import path from 'path'
import dts from 'rollup-plugin-dts';

export default [{
    //入口文件
    input: "./src/sdk/index.ts",
    output: [
        //打包esModule
        {
            file: path.resolve(__dirname, './sdk-dist/index.esm.js'),
            format: "es"
        },
         //打包common js
        {
            file: path.resolve(__dirname, './sdk-dist/index.cjs.js'),
            format: "cjs"
        },
       //打包 AMD CMD UMD
        {
            input: "./src/sdk/index.ts",
            file: path.resolve(__dirname, './sdk-dist/index.js'),
            format: "umd",
            name: "tracker"
        }
 
    ],
    //配置ts
    plugins: [
        ts(),
    ]
}, {
    //打包声明文件
    input: "./src/sdk/index.ts",
    output:{
        file: path.resolve(__dirname, './sdk-dist/index.d.ts'),
        format: "es",
    },
    plugins: [dts()]
}]

sdk/index.ts

export default class MySdk {

  public name: string;
  public version: string;
  public fn:()=>void;

  public constructor(options: any) {
    this.init(options)
  }

  private init(options: any): any {
    this.name = "my-sdk"
    this.version = "1.0.0"
    this.fn = ():void=>{
      console.log("hello sdk")
    }
    if(typeof options === 'object'){
       Object.keys(options).forEach((key:string)=>{
        this[key] = options[key]
      })
    }
    
    console.log("this",this)
  }

}

创建好上面的 sdk.config.js 和 sdk/index.ts 文件后

就可以打包 sdk 包了

pro.config.js

import ts from 'rollup-plugin-typescript2'
import path from 'path'
import dts from 'rollup-plugin-dts';
import commonjs from '@rollup/plugin-commonjs'

export default [{
    //入口文件
    input: "./src/pro/index.ts",
    output: [
        //打包esModule
        {
            file: path.resolve(__dirname, './dist/index.esm.js'),
            format: "es"
        },
         //打包common js
        {
            file: path.resolve(__dirname, './dist/index.cjs.js'),
            format: "cjs"
        },
       //打包 AMD CMD UMD
        {
            input: "./src/pro/index.ts",
            file: path.resolve(__dirname, './dist/index.js'),
            format: "umd",
            name: "tracker"
        }
 
    ],
    //配置ts
    plugins: [
        commonjs(),
        ts(),
    ]
}, {
    //打包声明文件
    input: "./src/pro/index.ts",
    output:{
        file: path.resolve(__dirname, './dist/index.d.ts'),
        format: "es",
    },
    plugins: [dts()]
}]

/pro/index.ts

import sdk from '../../sdk-dist/index'

const MySdk = new sdk({
  url:"127.0.0.1"
})

MySdk.fn&&MySdk.fn()

在 /pro/index.ts 上使用我们前面打好的sdk包
