Add config for compressing options before chrome.sync.set

[mjmaurer]

Thanks for all these awesome webext libraries!

The sync.set serialization isn't the most transparent, but from what it sounds like it might be something like JSON.stringify

The storage.sync capacity is 100Kb so I think the smaller the better here.

Could use something like lz-string + JSON.stringify to seriazlize + compress / decompress + deserialize the options map

Indeed, it looks like that's what they're using:

chrome.storage.sync.getBytesInUse(console.log)
// -> 4256

chrome.storage.sync.get(data => console.log(JSON.stringify(data).length))
// -> 4261

This library is pretty small: https://bundlephobia.com/result?p=lz-string@1.4.4

I tried compressing my Refined GitHub options and that number went down to 850 bytes, which is pretty good. It should probably be enabled by default.

The compression takes 7ms on RunKit and the decompression about 2ms.

sweet! feel free to assign to me. I think I'll have some time

Sure, if you have time it would be great. It should probably be enabled by default but it should still be able to read the uncompressed options to allow an easy migration of existing users. Then the options can be compressed on the successive save

Hi, first and foremost - thanks for this awesome little package! 👍
As I need this feature for another project - I implemented the compression in #40.

I am using compressToEncodedURIComponent - as I found that the compression rate was actually higher for js objects.

What do you think?

Fixed by #40

Available in v1.2.0
