[Feature] Make layout persistent

[robsontenorio]

Thanks for your time! Nice work!

Would be nice to have a persistent layout (diagram).

• Open http://localhost:8080/schematics
• Move around some objects
• Open a icognito browser http://localhost:8080/schematics
• Diagram layout has lost.

Hi again @robsontenorio! :)

Thanks!

The diagram saving relies on the localStorage which gets lost when you open a incognito screen. You could use the export / import to restore it though.

Maybe in the future I could save the diagrams somewhere else so they'll go along with incognito or browser switching. I'll have to think of a implementation.

I think you could use a database, or Redis to save the layout.

@ArtNous Yeah, could definitely be an option. I went for localStorage to make it the least "intrusive" as it could be.

Thinking about it I'm actually leaning towards using backend caching.

Will be a heavy change since pretty much everything you do gets stored in it (dragging positions etc.)

[robsontenorio]

You could keep all current logic using localStorage. But just send back to backend and save all changes on dedicated table.

In fact would be necessary to have a persitent mechanism, like a table.

EDIT: or maybe a simple file on proper location.

That's right, It would be a big change, but I think it is necessary, we're here to support and help.

Thanks guys! All contributions will be fully credited of course. Just have to make a nice section for it in the README as I didn't thought this would happen so fast. :)

I'll take the suggestions with me.

At the moment I'm working on a "hybrid" solution for this. I'm thinking of a save button in the right upper corner which will cache the localStorage. With that, if the localStorage is empty, it could fill it with it. This way we'll prevent a request bombardment. :)
