clearAll() removes everything in ionic Storage about ionic-cache HOT 5 CLOSED

We definitely need some prefix for cache items

from ionic-cache.

Wow, "clearAll() removes everything from storage", that will destroy my app local storage.. NOT a good idea.

from ionic-cache.

Would also be nice to be able to wildcard the removal of cached items e.g.

this.cache.removeItem('/projects/1/*');

This would be very useful since most of the time we are dealing with Rest APIs e.g.

GET /projects   -> Cached
GET /projects/1/something  -> Cached

Then to simply remove/invalidate the cache when say creating a new project, I could add the invalidation into a http interceptor:

if (method == 'POST' && path == '/projects/*') {
  this.cache.removeItem('/projects/*')
}

Right now, the only way to achieve this is to iterate over ionic storage looking for matching keys and then individually remove the items from the cache. This works, but it's messy and is a maintenance concern.

Would lend a hand to implement, but completely snowed under at the moment :-(

I've added the wildcard removal in commit af2ddcd

I'm currently thinking through the best way to add some sort of prefix (or similar idea), while maintaining backwards compatibility.

I've added a key prefix in commit 3ea632e
