import serve from 'rollup-plugin-serve'

import babel from 'rollup-plugin-babel';

import resolve from 'rollup-plugin-node-resolve';

import commonjs from 'rollup-plugin-commonjs';

// rollup 可以帮我们打包es6的模块化语法

export default {

input:'./src/ad-micro.js',

output:{

file:"./lib/umd/ad-micro.js",

format:'umd',

name:"adMicro",

sourcemap:true

},

plugins:[

serve({

openPage:'/index.html',

contentBase:'',

port:3000

}),

babel({

runtimeHelpers: true,

exclude: 'node_modules/**',

presets: ["@babel/preset-env"]

}),

resolve(),

commonjs()

]

}

.babel配置如下：@babel/plugin-transform-runtime 解决regeneratorRuntime is not defined 必备的包

{

"presets": [

"@babel/env"

],

"plugins": [

["@babel/plugin-transform-runtime", {

"regenerator": true

}]

]

}

最后
