Summary of Changes

Hello @Abhijit-2592, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a minor but significant improvement to the build-and-start npm script. By enabling argument forwarding, developers can now seamlessly pass custom options directly to the start command when executing npm run build-and-start, thereby streamlining the process of launching the application with specific configurations or tools.

Highlights

• Script Argument Forwarding: The npm run build-and-start script has been updated to correctly forward command-line arguments to the underlying npm run start command, enhancing flexibility for development workflows.

Changelog

• package.json
  • Modified the build-and-start script definition to include --, which ensures that any arguments provided to npm run build-and-start are properly passed on to the npm run start command.

Activity

• No human activity (comments, reviews, or progress updates) has been recorded on this pull request yet.

Code Review

This pull request updates the build-and-start npm script to correctly forward command-line arguments to the start script. The addition of -- ensures that all arguments, including those that could be interpreted as npm options (e.g., -v), are passed to the underlying start.js script. This is a good correctness fix that makes the convenience script more robust. The change is correct and I approve it.
