Update layout props without crossing JS bridge #45

osdnk · 2018-08-01T10:05:37Z

Motivation

The problem occurs if we wish to update props which are not supported natively to be modifier via Aniamted.Value. It refers to props like top, width etc.

Changes

Initially wish to add handling for greater number of properties in RN core which came out to be quite difficult and I gave up with this idea.
The another approach I decided to try was to use flow of updating properties from JS, but call them from native code.
Before these changes the flow was:

Changing property not supported natively e.g. width:

Animated Value is being changes as result of animation

The bias of passing bridge seems to be extremely useless and therefore I managed to omit it.

now it looks more or less like:

Add comment:

Whitelist of view props that can be updated in native thread via UIManagerModule

Change NATIVE_PROPS_WHITELIST to UI_THREAD_PROPS_WHITELIST and also change comment to tell that the props are updated directly on UI thread

Change JS_PROPS_HANDLED_ to NATIVE_THREAD_PROPS_WHITELIST

I think we shouldn't just call onBatchComplete like that. This may intercept batched calls being made at the same time from JS. Would be the best to detect if we are in the middle of a batch and if so we can skip calling onBatchComplete and rely on getting it dispatched from JS thread. Also May be worth enqueuing all the UIManager operations here such that we can call it from a single runnable without risking some other operations being enqueued in the meantime

Lets keep the code responsible for updating props in JS. I believe there are still some props that we haven't whitelisted, we don't want to restrict usages that are curerntly possible

@kmagiera,
decided not to use onBatchCompleted because it sometimes makes unexpected behaviour.
While changing screen via navigator it sometimes "blink" with old layout (v easy to repro)
Indeed I figured out that batchId should not have any impact because it only matters in systrace.
https://github.com/facebook/react-native/search?q=batchId&unscoped_q=batchId&type=Code
But it makes this error 🤷‍♂️
