[santoslgl01-web]

Summary

• Add a Biome configuration for consistent JavaScript, JSON, and CSS formatting/linting.
• Wire Biome into the existing pre-commit setup with a local Node hook.
• Exclude generated users.json and image assets from Biome checks.

Fixes #120

Testing

• Parsed .pre-commit-config.yaml and biome.json successfully.
• Ran: npx --yes @biomejs/biome@2.3.8 check biome.json

Code Review

This pull request introduces Biome for linting and formatting by adding a new pre-commit hook and a corresponding biome.json configuration file. The review feedback suggests expanding the file extensions targeted by the pre-commit hook to include formats like .mjs and .jsonc. Additionally, several corrections were identified in the Biome configuration, including fixing the "include" property name, utilizing the "ignore" field for exclusions, and reconsidering the disabling of recommended correctness rules to maintain higher code quality.

Biome is not installed so we don't want a local hook.

Please use the standard biome hook. Thanks

[santoslgl01-web]

Updated to use the standard Biome pre-commit hook from biomejs/pre-commit as requested, and expanded the file pattern to cover common Biome-supported extensions. I also re-validated the updated pre-commit config locally with pre-commit. One unrelated local environment limitation remains: the repo currently pins the isort pre-commit hook to a version that requires Python >=3.10, while this machine has Python 3.9, so a full pre-commit run could not complete here. Please take another look when you have a chance — happy to make any further adjustments.

You can install a newer version of Python.

docs/users.json is excluded only in the pre-commit hook, but not in Biome’s own file include/exclude rules. That means running Biome directly (e.g. biome check --write .) could still reformat this generated file, which contradicts the PR summary and the existing .prettierignore behavior. Consider excluding docs/users.json in biome.json as well so manual/local Biome runs and CI behave consistently with pre-commit.

PR description says Biome is wired into pre-commit via a “local Node hook”, but the change uses the upstream biomejs/pre-commit repo hook instead. Please either update the PR description to match the actual implementation or switch to a local hook if that’s a requirement (e.g., to avoid depending on the remote hook repository).

Thanks for the review. I’m working on updating this from a newer Python environment so I can rerun the repo’s expected tooling cleanly. For reference, I’m on macOS (Darwin arm64). I’ll push a follow-up once the requested changes are addressed.
