always run in transact() mode about freezer HOT 4 OPEN

Hey aktxyz

If you want to update 2 elements in something you can do

store.something.set({a:1,b:2});

Also the update methods are chainable so this will do the same, but it's less efficient since it updates the tree completely twice:

store.something
  .set(a, 1)
  .set(b, 2)
;

The first set(a,1) return the updated node to let you edit it again.

I think that transaction is a last resort mechanism, and I have found myself using it only twice in the years I've been using Freezer. You need to update the whole tree hundreds of times in the same tick to feel that there is a performance object, so if I am not doing hundreds of updates I never use it.

I use the 2 methods you describe quite a bit also, but there are cases where the code for the store updates are not all together, so end up having to .transact() to work.

If I do a .transact() at the root, will that apply to all children?

from freezer.

I usually organize the functions that update the state by the part of the state they update. Eg, for I would create a file, somethingReactions.js to edit what's inside of something.

In that file I use to create a helper function to make simpler run the updates something like:

// 'd' after 'domain'
var d = function (){ return freezer.get().something };

That way I rest assured that I am updating the current content of the store:

d().set('a',1);
d().set('b',2);

I think transact is not a good thing to use so lightly, because it works stopping the tree updates on that node and if I don't call run immediately after using it, I feel like I am loosing the control of what's happening. I might be doing some other updates to the store before the transaction run, without knowing that there is a transaction going on, maybe in the same store branch I am working.

That's the reason that I never use it, unless I have to make lots of updates in one node's children, and I always call run afterwards.

By the way, I am writing an article to celebrate the 1000 stars, where I try to explain how I use freezer :)
