安装依赖

• rollup 打包工具
• rollup-plugin-node-resolve 依赖引入插件
• rollup-plugin-commonjs commonjs 转换
• rollup-plugin-eslint eslint 校验
• rollup-plugin-typescript2 ts 转换
• @typescript-eslint/parser eslint ts 解析器
• typescript ts解析器

rollup 配置

代码语言：javascript复制

import path from 'path'
import resolve from 'rollup-plugin-node-resolve' // 依赖引用插件
import commonjs from 'rollup-plugin-commonjs' // commonjs模块转换插件
import { eslint } from 'rollup-plugin-eslint' // eslint插件
import ts from 'rollup-plugin-typescript2'
const getPath = _path => path.resolve(__dirname, _path)
import packageJSON from './package.json'


const extensions = [
  '.js',
  '.ts',
  '.tsx'
]


// ts
const tsPlugin = ts({
  tsconfig: getPath('./tsconfig.json'), // 导入本地ts配置
  extensions
})


// eslint
const esPlugin = eslint({
  throwOnError: true,
  include: ['src/**/*.ts'],
  exclude: ['node_modules/**', 'lib/**']
})


// 基础配置
const commonConf = {
  input: getPath('./src/index.ts'),
  plugins:[
    resolve(extensions),
    commonjs(),
    esPlugin,
    tsPlugin,
  ]
}
// 需要导出的模块类型
const outputMap = [
  {
    file: packageJSON.main, // 通用模块
    format: 'umd',
  },
  {
    file: packageJSON.module, // es6模块
    format: 'es',
  }
]


const buildConf = options => Object.assign({}, commonConf, options)


export default outputMap.map(output => buildConf({ output: {name: packageJSON.name, ...output}

typescript配置 tsconfig.json

{
  "compilerOptions": {
    "baseUrl": ".",

    "lib": ["esnext", "dom"],  // 导入库类型定义
    "types": ["node"] // 导入指定类型包

eslint 配置 .eslintrc.js

const path = require('path')
const resolve = _path => path.resolve(__dirname, _path)
const DOMGlobals = ['window', 'document']
const NodeGlobals = ['module', 'require']


module.exports = {
  env: {
    browser: true,
    es6: true
  },
  parser: '@typescript-eslint/parser', // 配置ts解析器
  parserOptions: {
    project: resolve('./tsconfig.json'), 
    tsconfigRootDir: resolve('./'),
    sourceType: 'module'
  },
  // plugins: ['prettier'],
  rules: {
    'indent': ['error', 2],
    'no-unused-vars': 'error',
    'no-restricted-globals': ['error', ...DOMGlobals, ...NodeGlobals],
    'no-console': 'off',
    }

package.json

{
  "main": "lib/index.js",
  "module": "lib/index.esm.js",
