Range search for localstorage and session storage

[anuragvohraec]

What problem are you trying to solve?

Storage interface of the WebStorage API should have a range search feature to pull out multiple value out of Storage interface.

What solutions exist today?

None

How would you solve it?

Solutions:

1. Add getItems method to storage interface

Storage.getItems(lowerKey,upperKey,lowerOpen,upperOpen,direction);

2. Add nextKey and prevKey methods to storage interface.

Storage.nextKey(key1);//this will give next key after the key1
Storage.prevKey(key1);//this will give prev key before the key1

Anything else?

No response

do you have a fuller example of what you're trying to accomplish and how the current api falls short?

I wanted to fetch out a range of values from Storage interface. For example get me all values in between fruit-apple and fruit-orange.
One can't do that with the current Storage interface as it allows only pulling out single value using getItem.

So I suggest we should have a feature to pull out range of values out of Storage interface.

Are there any libraries that offer this functionality and how popular are they?

In general though I would not expect us to add much new functionality to localStorage or sessionStorage as they unfortunately offer synchronous I/O which is not great for performance.

Indeed. I'd rather have some reasonable API on top of IndexedDB, or make IndexedDB itself easy to use.

There are no libs to work on top of Storage api. As the underlying lib do not have any kind of iterators or complex search feature themselves.

yeah IDB can be used, but cases where Storage(local/session) is needed there in we do not have some complex search features to help out.

Let's close this, as we have signals from multiple implementers that the sync storage APIs are not going to be extended.
