[mabels]

@jchris if you want help here is something!

It's a lot of editing, but it should not be hard. pls do not use any casts or ignore comments. If something is not clear how to resolve -> ask.

Walkthrough

This pull request introduces a comprehensive set of type refinements, code simplifications, and configuration updates across the Fireproof project. The changes primarily focus on enhancing type safety, removing unnecessary type assertions, and streamlining type definitions. Key modifications include updating ESLint configurations, adjusting TypeScript configurations, and making subtle changes to type handling in various source and test files. The modifications aim to improve code clarity, reduce potential runtime errors, and leverage TypeScript's type inference capabilities more effectively.

Changes

    Developer->>TypeScript: Modify type definitions

    Project->>ESLint: Enforce new type rules
    ESLint->>Developer: Provide type-related feedback
    Developer->>Project: Refine code based on feedback

This diagram illustrates the iterative process of type refinement, where developers modify type definitions, TypeScript applies stricter checking, ESLint enforces rules, and developers further refine the code based on the feedback.

2-2: LGTM! Good practice to ignore ESM cache directories.

The addition of **/.esm-cache/** is appropriate as these directories contain temporary build artifacts from ES module processing that should not be version controlled.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

I've created a demonstration PR that shows the scope of this change: #1159

That PR contains only the eslint.config.mjs changes from this PR, and running pnpm lint reveals 2,304 lint errors. This confirms that this PR (#465) is essentially:

1. The core change: Upgrading ESLint to type-checked rules (in eslint.config.mjs)
2. The massive cleanup: Fixing all 2,304+ resulting lint violations across 39 files

So yes, eslint.config.mjs is really the only "change" - everything else is cleanup to handle the new stricter linting rules. The scope is enormous but it's all automated fixes for type safety violations.

See #1159 for the isolated config change and full error breakdown.
