> Master different caching strategies to optimize performance and offline capability.

## Strategy patterns

Caching strategies determine when to serve cached vs. fresh content. Common patterns include cache-first, network-first, stale-while-revalidate, and race.

## Caching strategy flows

Visualize the decision trees for different caching strategies.

## A common trap

Different resources need different strategies. Use cache-first for static assets, network-first for HTML, and stale-while-revalidate for APIs.
