[ANN] Plato 0.1.5

[Henrik]

Plato is a ClojureScript library for storing and restoring atom content to and from Local Storage.

https://github.com/eneroth/plato

The library grew out of a need to manage front end storage and persistence in apps based on Om and Reagent.

The arguably most useful function in the library is "keep-updated!", which watches an atom for changes, and selectively updates local storage to be consistent with the atom. The goal is for storage management to be handled separately from all other application logic and not become (as it was in my case anyway) interspersed with all other code.

The library is very alpha, so all forms of feedback are welcome. :-)

There is similar library - https://github.com/alandipert/storage-atom

You can use clojure.diff to find differences -

Thanks for the feedback, Eduardo!

Storage atom stores the entire atom on swap!, and it seemed to me that storing increments might be more frugal.

If you look at diff, you'll see that it diffs all collections, including vectors and so on. I only want to diff maps, everything else counts as a value, so the path of least resistance seemed to be to implement an algorithm that did exactly that and nothing else. Perhaps diff can be easily tweaked to achieve this, but I couldn't figure out how.


Best regards,

Henrik

This looks really useful, thanks! I was just thinking about local storage for my Om app :)
