Key Concepts

Condition Compilation

Use special comments to write platform-specific code:

<!-- #ifdef APP-PLUS -->
<view>App only</view>
<!-- #endif -->

<!-- #ifdef MP-WEIXIN -->
<view>WeChat only</view>
<!-- #endif -->

API Promise Support

Most uni-app APIs support Promise when no callback is provided:

const res = await uni.request({ url: 'https://api.example.com' })

Cross-Platform Best Practices

1. Use uni-app components and APIs instead of platform-specific ones
2. Use condition compilation for platform-specific features
3. Test on all target platforms
4. Use rpx for responsive layouts
5. Handle platform differences in manifest.json
