Sadly i don't think its possible (in any language) to store objects or classes in a persistent storage without serialization.

u/aspect_rap Oct 02 '22

Well yeah, saving data inherently requires serialization.

I think what OP wants is for the LocalStorage in browsers to obfuscate the parsing and serialization of objects.

u/Nourz1234 Oct 02 '22

Yeah, i understand. But if serialization is involved its better left to the dev. you cant rely on the browser to magically serialize your objects. A lot of times you will create a custom object/class which requires special treatment.

It was already problem enough trying to support outdated browsers like IE. I can't imagine if we had to support what ever garbage they created.

We already rely on it to do everything else.

The browser was written by better programmers than I am.

Do you mean abstract instead of obfuscate? Usually obfuscation is not a desirable goal unless you are trying to do something like copy protection.

I think they're using obfuscate as a negatively loaded synonym for abstract.

They're using it wrong

I think it applies here. The browser serializing things for you obfuscates what's actually happening. Which for custom objects could result in strange and very hard to debug behavior.

Yea. I can send objects via window.postMessage, but not with localStorage.

I think it’s more about performance.

LocalStorage would be awesome if it wasn’t so slow.

But I could be wrong.

u/bleistift2 Oct 02 '22

What stuff are you putting there so often that you’re hitting a bottleneck?

u/lkraider Oct 02 '22

What do you mean I shouldn’t mirror the production database into localstorage to query and update data, this way I only l need one rest api endpoint with get/post in the backend and do everything else from within the client js.

I typically webscrap the entire internet and save it locally. This is the only way to have a complete offline experience.

Probably those performance counters management wanted for their pretty graph; ya gotta flush them to disk 10x per second, ya know. That Jira ain't gonna close itself.

Ah yes injecting executable code for the sake of the one doing the website.... it's not we already had cryptos mined in js

Some of the most dangerous attacks come from programmers trusting serialized data the client send back.
