Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1485 X-link: https://github.com/facebook/react-native/pull/41686 The size of the containing block is the size of the padding box of the containing node for absolute nodes. We were looking at `containingNode->getLayout().measuredDimension(Dimension::Width)` which is the border box. So we need to subtract the border from this. Added a test that was failing before this change as well Reviewed By: NickGerleman Differential Revision: D51330526 fbshipit-source-id: adc448dfb71b54f1bbed0d9d61c5553bda4b106c
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.
