Added a runtime check to throw an error if the Node.js version is unsupported, ensuring the package is only used in compatible environments.

Summary of Changes

Hello, 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 crucial compatibility safeguard by adding a runtime Node.js version check, ensuring the rslog package operates within its supported environments. It prevents potential issues arising from incompatible Node.js versions or alternative JavaScript runtimes like Bun and Deno, thereby enhancing the package's stability and user experience.

Highlights

  • Node.js Version Enforcement: Implemented a runtime check in src/color.ts to ensure the package runs only on Node.js versions ^20.19.0 || >=22.12.0 and throws an error if an unsupported version or environment (Bun, Deno) is detected.
  • Documentation Update: Updated README.md to clearly state the new Node.js version requirements, informing users about the necessary upgrade if they are on older versions.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog
  • README.md
    • Updated the stated Node.js version requirement from >= 14 to ^20.19.0 || >=22.12.0.
    • Added a prominent note advising users on Node.js 18 to upgrade.
  • src/color.ts
    • Replaced import { styleText } from 'node:util'; with import util from 'node:util';.
    • Introduced a checkNodeVersion function that verifies the Node.js version is ^20.19.0 || >=22.12.0 and not running in Bun or Deno, throwing an error if conditions are not met.
    • Modified createStyler to use util.styleText instead of the destructured styleText.

Code Review

This pull request adds a runtime check to enforce the minimum Node.js version. The implementation in src/color.ts has a flaw where it incorrectly allows older, unsupported Node.js versions to pass the check due to using feature detection that is too broad. I've suggested a more robust implementation that correctly checks the Node.js major version. Additionally, the PR description is inconsistent with the code's handling of Bun and Deno, which you may want to correct.
