@yinanazhou I sympathize with your interest in prettifying the code… However, I must ask you to maintain the formatting used so far. By changing the formatting of almost every file in the repo, this PR produces countless "nonessential" diffs, and would make it impossible to compare your revisions against past commits….

So, could you either undo the formatting, or adjust your linter to use the same settings as those used in the past?

Sorry about the hassle.

Thanks for the feedback! I totally understand your concern about the nonessential diffs, and I wouldn’t have made these changes if I had found a better way.

Just to clarify, a formatter automatically enforces consistent code style, while a linter primarily checks for potential issues without fixing them. This project uses ESLint as a linter, but there wasn’t a formatter configuration in place before. I also noticed inconsistencies in style both within and across files (e.g., tab size). Since there was no existing standard, introducing a formatter seemed like the easiest way to align styles rather than fixing everything manually.

That said, I’m happy to adjust to any preferred style if you have one, though some changes would be unavoidable. Please let me know how you’d like to proceed.

So, @yinanazhou my suggestion is to revert all formatting changes and keep only the "essential" (i.e. dependency-related) changes.

By the way, issue #246 is specific to this PR, correct? (I don’t think it appears in any other branch of the app). If so, it would be best to keep PR-related bugs as comments within the PR. Does that make sense?

(Alternatively, @yinanazhou if we do open a GitHub issue for a PR-specific thing, it’s best to link the PR and the issue, so that the issue is automatically closed when the PR is merged.)

Looks good, @yinanazhou! Feel free to merge.
