Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1498 The only instance of ruby in this repository is `gentest.rb` used to generate test cases from html fixtures. This is quite annoying as ruby is not the most popular compared to something like Node and it does not integrate into the rest of our stack. I changed this to use Node.js instead. Instead of `watir` we now use `selenium-webdriver`. `watir` is backed by Selenium so I do not expect anything to change. Next commits will add command line options, clean up gentest.rb and its references, and change the README allow-large-files Reviewed By: yungsters, NickGerleman Differential Revision: D51874433 fbshipit-source-id: ef8588d48aa7f8b720b57df08738bbd01e9e74a3
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.
