A comment on Persisting React State in LocalStorage.

I remember people were abandoning localstorage a while ago because of some fundamental problem I can't quite remember right now. Not sure if it was difficulty in keeping in sync which the author mentions or the fact that it can't be scoped in a way to share among subdomains. I'm sure someone here will have a better memory than me.

Edit: after some basic research among other complaints are: bad performance, synchronous, bad security model, only strings, limited to 5mb, no access to web workers.

Localstorage has its uses but shouldn't be abused to store everything in it.

The "bad security model" applies to storing things like tokens; it's an argument against using JWTs and localStorage as an alternative to secure cookies. It doesn't apply here.

Re web workers: is anyone (apart from Google) using this in practice? I assume Photopea and similar apps could benefit from it in some specific cases, but haven't had the need for them myself. Am I missing something?

I've experimented with using it together with TensorFlow.js to avoid blocking the UI thread while performing computationally expensive operations. Operations do take a bit longer to complete in a web worker compared to the main thread, but in return you get a smooth UI and a better user experience

Last I checked, they can only pass messages to the main thread as strings. All that (de)serialization can easily become a bottleneck, depending on the workload.

Yes we use it for relatively heavy processing in our web app. To not block the UI and allow offline use
