目前支持 wxml、wxs、js/ts、json，less/sass 等文件类型，资源支持通过配置区分不同平台

wxml中使用 

<!-- #if MP --><view class="test-view">wechat</view><!-- #elif IOS --><view class="test-view">iOS</view><!-- #elif ANDROID --><view class="test-view">android</view><!-- #endif -->

wxss

.test-view{/* #if MP */color: red;/* #elif IOS */color: green;/* #elif ANDROID */color: yellow;/* #endif */
}

 

js中微信小程序登录：

// #if MP
wx.login({})// #elif IOS
wx.getMiniProgramCode({})// #elif ANDROID
wx.getMiniProgramCode({})// #endif

JSON

{"window": {"navigationBarTitleText": "Weixin",},"mini-wechat": {"window": {"navigationBarTitleText": "wechat demo"}},"mini-ios": {"window": {"navigationBarTitleText": "iOS demo"}},"mini-android": {"window": {"navigationBarTitleText": "android demo"}}
}
