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>

# path-exists [](https://travis-ci.org/sindresorhus/path-exists)
|
|
|
|
> Check if a path exists
|
|
|
|
NOTE: `fs.existsSync` has been un-deprecated in Node.js since 6.8.0. If you only need to check synchronously, this module is not needed.
|
|
|
|
While [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it.
|
|
|
|
Never use this before handling a file though:
|
|
|
|
> In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there.
|
|
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install path-exists
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```js
|
|
// foo.js
|
|
const pathExists = require('path-exists');
|
|
|
|
(async () => {
|
|
console.log(await pathExists('foo.js'));
|
|
//=> true
|
|
})();
|
|
```
|
|
|
|
|
|
## API
|
|
|
|
### pathExists(path)
|
|

Returns a `Promise<boolean>` of whether the path exists.
|
|

|
### pathExists.sync(path)
|
|
|
|
Returns a `boolean` of whether the path exists.
