import Taro from '@tarojs/taro'

const ENV = Taro.getEnv()

process.env.TARO_ENV

https://nervjs.github.io/taro/docs/envs.html#processenvtaro_env

// 如想在微信小程序和 H5 端分别引用不同资源

if (process.env.TARO_ENV === 'weapp') {
  require('path/to/weapp/name')
} else if (process.env.TARO_ENV === 'h5') {
  require('path/to/h5/name')
}

// 同时也可以在 JSX 中使用，决定不同端要加载的组件

render () {
  return (
    <View>
      {process.env.TARO_ENV === 'weapp' && <ScrollViewWeapp />}
      {process.env.TARO_ENV === 'h5' && <ScrollViewH5 />}
