This demonstrates the build error that arises with the explicit
addition(/duplication) of @babel/plugin-proposal-class-properties in the
default babel config for
react-native-builder-bob.
This package is a fresh invocation of yarn create react-native-library, and
the only changes are updating src/index.tsx and deleting the example/
directory.
The file src/index.tsx is a minimal clone of react-native-svg's Symbol
component.
It includes the bare minimum repro that requires all three of these features:
export default class- class name shadowing the
Symbolglobal - static class property
Removing the explicit plugin restores @babel/preset-env's natural transform
ordering and allows this library to build without issue.
The easiest way to test this is to manually remove line 75 in
node_modules/react-native-builder-bob/lib/utils/compile.js in your local node
modules.
Created for react-native-builder-bob/pull/363.
