Optimizing React Performance for Mobile

Mobile networks in London are fast, but rural UK coverage can be spotty. Your app needs to perform well on 4G and even 3G connections.

Code Splitting

Next.js does this automatically at the route level, but you should also use React.lazy for heavy components below the fold.

Image Optimization

Use the <Image> component with avif format. It offers superior compression compared to WebP.

Reducing JavaScript Execution

The main thread on mobile devices is easily blocked. Offload heavy computations to Web Workers or, better yet, the server.
