Summary: X-link: https://github.com/facebook/react-native/pull/41480 Pull Request resolved: https://github.com/facebook/yoga/pull/1469 The previous version of static didn't do anything inside of Yoga. Now that we're making it do something, this changes the default back to relative so that users with no errata set don't see their deafult styles changing.

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();
Using TypeScript
This package provides out-of-the-box TypeScript typings so long as tsc
is configured to support ESM resolution. It is recommended to set moduleResolution: 'bundler'
or moduleResolution: node16
in your tsconfig.json
according to your environment.
ES Modules
yoga-layout
is only provided as an ES Module, relying on top-level await. This allows providing a synchronous API, while still allowing async WebAssembly compilation in browsers, and will allow eventual usage of ESM/WASM interop.
