Great Article,

Since i was looking for something to exclude API url from service worker. Your strategy combined with
```
workbox.routing.registerNavigationRoute(
workbox.precaching.getCacheKeyForURL(“/index.html”),
{
blacklist: [/^\/api/, /^\/auth/, /^\/sitemap/, /^\/robots.txt/]
}
)
```

help me fix an issue on the default cache of the CRA service worker
