Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1721 X-link: https://github.com/facebook/react-native/pull/46938 The private internals of how we store styles needed to change a bit to support 3 new keyword values. Right now the only other keyword that can be stored is `auto`. As a result there isn't much fancy logic to support storing this and its just stored as a specific type inside of `StyleValueHandle`. There are only 3 bits for types (8 values), so it is not sustainable to just stuff every keyword in there. So the change writes the keyword as a value with a new `keyword` `Type`. I chose not to put `auto` in there even though it is a keyword since it is a hot path, I did not want to regress perf when I did not need to. I also make a new `StyleSizeValue` class to store size values - so values for `width`, `height`, etc. This way these new keywords are kept specific to sizes and we will not be able to create, for example, a margin: `max-content`.

yoga-layout
This package provides prebuilt WebAssembly bindings for the Yoga layout engine.

Usage
import {Yoga, Align} from 'yoga-layout';
const node = Yoga.Node.create();
node.setAlignContent(Align.Center);
Objects created by Yoga.<>.create() are not automatically garbage collected and should be freed once they are no longer in use.
// Free a config
config.free();
// Free a tree of Nodes
node.freeRecursive();
// Free a single Node
node.free();
Requirements
yoga-layout requires a toolchain that supports ES Modules and top-level await.
If top-level-await is not supported, use the yoga-layout/load entry point instead. This requires to load yoga manually:
import {loadYoga, Align} from 'yoga-layout/load';
const node = (await loadYoga).Node.create();
node.setAlignContent(Align.Center);
