Quickapp's internal storage

[Neo Andersson 230]

Hi

Anyone by chance have some closer info about a quickapp's internal storage? What is it for, how to use it? And some pro/contra against quickapp variables?
I see internal storage usage in some of @jgab 's quickapps but i could not find it.

Well, I mostly use them because they are not cluttering up the quickAppVariables view for data that I want to persist between QA restarts.
They are also not saved with the QA as quickAppVars are.
That's the reason I use them.

As for efficiency and amount of data that can be stored I haven't tested - but in general, be careful about all types of resources on the HC3...

Same as @jgab, using them to reduce number of needed quick app variables and that last data is available during the quick app restart process.

As for data type, I use them to store tables, strings and numbers and amount of stored data is always reduced to a minimum needed so don't know for any limits.

Ohh, so i misunderstood something..Jgab said, it doesnt survive QA restart. Does it then? Becuase i would rather store table in internal storage too, if it survive QA restarts.

No, I didn’t say that - I said the opposite.

I deducted this from this part of your answer.."They are also not saved with the QA as quickAppVars are."
my bad, i misunderstood it

Any help for the syntax? How to save them, how to read them?
Would be verry helpful

It's
QuickApp:internalStorageGet(key)

QuickApp:internalStorageSet(key, value)

QuickApp:internalStorageRemove(key)

...and some tricks how to retrieve all keys and hide them...

You can create a metatable in self.store and use that for your persistent values like this:
