Conversation
- Refactor loadConfig in src/config.ts to parse CLI flags using node:util parseArgs and load config.json (or custom --config file). - Ensure CLI flags take precedence over config.json file values, with sensible default fallbacks. - Remove environment variable loading (process.env) for configuration. - Update src/main.ts to support passing CLI arguments or config options into start/boot. - Update test suites and README.md to reflect the CLI flags and config.json configuration mechanism.

I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

Summary by CodeRabbit
WalkthroughConfiguration now loads from CLI arguments or JSON files with defined precedence and validation. Startup accepts loaded configuration or loading options. Unit and integration tests no longer configure the application through environment variables. ChangesConfiguration and startup
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR currently has a reported duplicate declaration that may prevent an updated E2E test module from loading, and empty port values can be interpreted as port 0 instead of rejected. Merge should wait for the test-loading issue to be fixed or explicitly accepted, with port validation corrected as follow-up. Possibly related PRs

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject empty port strings before numeric conversion.
Number(rawPort.trim()) converts "" and whitespace-only strings to 0. Therefore --port "" and { "port": " " } select an ephemeral port instead of failing validation. Reject an empty trimmed string before conversion. Add CLI and JSON-file test cases.
Proposed fix

+ const portText = typeof rawPort === "string" ? rawPort.trim() : undefined;
+ const numPort =
typeof rawPort === "number"
? rawPort
- : typeof rawPort === "string"
- ? Number(rawPort.trim())

Replaced environment variable configuration with CLI flags and
config.jsonsupport. Config options are parsed via CLI flags usingparseArgsfromnode:utiland loaded fromconfig.json(or a custom path via--config/-c). CLI flags overrideconfig.jsonfile settings. Updated tests, entrypoints, and documentation accordingly.PR created automatically by Jules for task 9357351157988310267 started by @abhi-kr-2100
