Progressive Web Apps with React

Setting up our cache

In this section, we'll move through our three main service worker life cycle events, and interact with our cache individually in each event. By the end, we will have automatic caching for all static files.

A warning, though--working with caches in development is, at best, tolerable, and at worst, infuriating. "Why aren't you updating?" we yell at our screen, until we realize that our cache has been serving up old code; it happens to the best of us. In this section, we'll take steps to avoid caching our development files and dodge this bullet, but in the future, remember that weird errors are probably caused by caching.

There are only two hard things in Computer Science: cache invalidation and naming things.
