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