Feature: Maximum depth to $watch / $watchCollection

[caitp]

I've got a set of directives which deal with a tree structure. The tree structure is represented by an object with a property containing child objects with the same structure (that's fairly obvious).

So, this is great and all, but $watchCollection and $watch have a bit of a problem, because given that the model is nested, and each node deals with a particular (possibly) non-leaf branch of the tree, then for a tree with many levels, the $watching can become quite expensive.

I propose that the depth of checks be limit-able, so that non-leaf nodes don't end up checking a whole bunch of stuff in the model that they don't need to (since those checks will be performed elsewhere anyways).

I'm happy to put together a patch to do this, but I'm interested in hearing if it's a desirable feature or not.

I'm not a fan of this.

@caitp do you still care about this feature? if not, can we close this issue and the PR?

[caitp]

I think it would be useful to have it

[caitp]

up to you though

I don't understand why $watchCollection does not provide the facility you need @caitp. Can you elaborate? In the meantime, moving to the IceBox.
