Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1496 Gentest code has a problem where we try to apply a border in our test when the web browser is not actually adding one. This happens when we do something like `border-top: 10px`. This will actually set the style of the border to `initial` which is just `none`, so nothing renders. This is causing at least 1 test to pass when it actually fails. I changed it so we ignore setting this value if the style is one of these values. I then re-ran the gentest code and excluded the now failing test (which gets fixed in my static stack).

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.
