shared

A Roblox Lua port of the shared pseudo-package from React, which contains a number of common utilities and definitions used across the React monorepo.

Status: ✔️ Ported

Source: https://github.com/facebook/react/tree/master/packages/shared

✏️ Notes

• ReactTypes.js contains a number of complex flow-type definitions that are not yet possible with Luau, so it's been simplified to a stub called ReactTypes.roblox.lua
• ReactComponentStackFrame.js is replaced by a partially-ported stub (ReactComponentStackFrame.roblox.lua) since it contains logic for parsing/navigating JS-specific stack structure. This needs to be ported to the equivalent functionality in Luau.
• Some slight changes to isValidElement.lua that account for the divergent shape of Component and PureComponent objects in our port (for react, they're functions; for us, they're tables)

Forks that specify different flag states are used in React with the help of a bundler that swaps in the correct file for the given environment. We don't have this kind of functionality yet, nor the same set of environments.

Integration Tests

__tests__/describeComponentFrame-test.js
__tests__/ReactError-test.internal.js

These tests required use of React and ReactDOM, and are not viable to port until we have more of the reconciler ported.
