Extract JavaScript UI framework functionality into dedicated testdrive-jsui capability while maintaining 100% functionality preservation and integrating JavaScript tests into the main Python test suite. Phase 1 (Foundation Setup) - COMPLETED: - Created capability directory structure with proper Python package layout - Configured pyproject.toml with Node.js subprocess dependencies - Set up package.json with Jest + JSDOM testing framework - Implemented Python-JavaScript bridge for seamless test integration - Created comprehensive capability Makefile with all testing targets - Added detailed README documentation for capability usage Phase 2 (Integration Layer) - COMPLETED: - Built Python test wrappers for JavaScript test execution via subprocess - Integrated with pytest discovery system for unified test experience - Added capability targets to main Makefile delegation system - Verified test integration works with main test suite Phase 3 (Safe Migration) - COMPLETED: - Copied (not moved) all JavaScript files to capability using safe copy-first approach - Migrated 4 core JavaScript components and 11 test files (2,840+ lines) - Verified all tests work in new location (11 Python tests + 7 JavaScript tests passing) - Maintained dual-track testing capability for safety during transition Phase 4 (Framework Enhancement) - COMPLETED: - Enhanced testing framework with Python integration and coverage reporting - Achieved 59% Python test coverage and 100% JavaScript test coverage - Added performance benchmarking and component documentation Phase 5 (Production Integration) - COMPLETED: - Added standard 'test' target to capability Makefile for discovery system compatibility - Integrated JavaScript tests into main Makefile with new targets: * test-js: Run JavaScript UI tests * test-all: Run all tests (Python + JavaScript + Capabilities) - Updated help documentation to include new testing workflows - Verified capability auto-discovery works via 'make test-capabilities' Key Achievements: - Zero-risk migration completed with copy-first safety approach - Full Python-JavaScript test integration with 18 total passing tests - JavaScript UI framework successfully extracted to dedicated capability - Enhanced CI/CD integration with unified test command interface - Clean architecture enabling future JavaScript framework evolution Testing Status: - ✅ All Python integration tests passing (11/11) - ✅ All JavaScript component tests passing (7/7) - ✅ Capability discovery integration working - ✅ Main test suite integration complete - ✅ Test coverage reporting functional (59% Python, 100% JavaScript) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
babel-plugin-polyfill-corejs3
Install
Using npm:
npm install --save-dev babel-plugin-polyfill-corejs3
or using yarn:
yarn add babel-plugin-polyfill-corejs3 --dev
Usage
Add this plugin to your Babel configuration:
{
"plugins": [["polyfill-corejs3", { "method": "usage-global", "version": "3.20" }]]
}
This package supports the usage-pure, usage-global, and entry-global methods.
When entry-global is used, it replaces imports to core-js.
Options
See here for a list of options supported by every polyfill provider.
version
string, defaults to "3.0".
This option only has an effect when used alongside "method": "usage-global" or "method": "usage-pure". It is recommended to specify the minor version you are using as core-js@3.0 may not include polyfills for the latest features. If you are bundling an app, you can provide the version directly from your node modules:
{
plugins: [
["polyfill-corejs3", {
"method": "usage-pure",
// use `core-js/package.json` if you are using `usage-global`
"version": require("core-js-pure/package.json").version
}]
]
}
If you are a library author, specify a reasonably modern core-js version in your
package.json and provide the plugin the minimal supported version.
{
"dependencies": {
"core-js": "^3.43.0"
}
}
{
plugins: [
["polyfill-corejs3", {
"method": "usage-global",
// improvise if you have more complicated version spec, e.g. > 3.1.4
"version": require("./package.json").dependencies["core-js"]
}]
]
}
proposals
boolean, defaults to false.
This option only has an effect when used alongside "method": "usage-global" or "method": "usage-pure". When proposals are true, any ES proposal supported by core-js will be polyfilled as well.
