🧩 Problem Statement

Our codebase currently lacks a fully enforced and consistent linting and formatting process. While the project is in its early stages, this has led to minor inconsistencies and potential technical debt that can snowball as the code grows. Enforcing and automating linting and formatting will ensure consistent code style, reduce review overhead, prevent subtle bugs, and improve maintainability. This is a foundational quality improvement that sets a solid developer experience and code hygiene baseline.

⚙️ Technical Context

• Repository: aldrin-labs/webtui
• Primary Language: Astro (with TypeScript)
• Tech Stack:
  • Linting & Formatting: @biomejs/biome (primary)
  • Build & Dev Tools: TurboRepo, TypeScript
  • Scripts: build, dev, format, format:check, lint, clean
• Current State:
  • Partial linting and formatting configs and scripts exist but enforcement is not strict or comprehensive.
  • No mandatory pre-commit or CI hooks to prevent non-compliant commits.
  • Some code inconsistency spotted in recent commits and PR reviews.
  • Existing tests may not cover linting validation.

---

🎯 Goals & Deliverables

• Analyze the current linting and formatting setup and codebase state.
• Identify gaps and areas for improvement in tooling, configuration, and enforcement.
• Implement a robust, automated linting and formatting pipeline integrated with local dev setup and CI.
• Guarantee backward compatibility and minimal disruption to developer workflow.
• Update tests and documentation to reflect new quality enforcement measures.
• Establish monitoring and reporting mechanisms to track linting errors over time.

---

🛠️ Detailed Implementation Steps

1. Audit Current State

   • Run full lint and format checks on the current repo snapshot.
   • Document all existing linting/formatting errors, warnings, and inconsistencies.
   • Review @biomejs/biome config files and scripts under package.json or config directories.
   • Assess pre-existing Git hooks or CI linting steps.

2. Design Improved Configuration

   • Define a strict but reasonable linting and formatting rule set aligned with community best practices for Astro and TypeScript.
   • Include rules for code style, unused variables, typing, import ordering, accessibility considerations, and Astro-specific syntax.
   • Extend or customize @biomejs/biome configs if necessary.

3. Implement Automation & Enforcement

   • Add or update format and lint scripts to run all checks and fixes.
   • Integrate lint/format checks into CI workflows (e.g., GitHub Actions).
   • Set up Git pre-commit hooks using tools like husky or lint-staged to automatically run format and lint checks on staged files.

4. Incremental Fixes & Backward Compatibility

   • Fix current linting and formatting errors incrementally to avoid massive PRs and enable easier reviews.
   • Document any exceptions or temporary disables with clear comments.
   • Ensure that no breaking changes occur in existing code behavior or developer environment.

5. Testing & Validation

   • Add automated tests or CI steps that fail builds if linting or formatting rules are violated.
   • Verify local developer experience by running lint and format commands manually and via Git hooks.

6. Documentation & Onboarding

   • Update CONTRIBUTING.md or create it if missing, with clear instructions on linting and formatting expectations and how to run the relevant commands locally.
   • Explain how the automated checks work in CI and pre-commit hooks.
   • Add troubleshooting tips for common linting failures.

7. Performance & Monitoring

   • Measure the impact of linting and formatting tasks on CI build times.
   • Optimize scripts or caching mechanisms if needed.
   • Consider adding linting status badges to the README or project dashboard.

---

🧪 Acceptance Criteria

• Comprehensive audit of current linting and formatting state documented.
• Updated, strict linting and formatting configuration implemented using @biomejs/biome.
• Local dev scripts (lint, format, format:check) fully functional and easy to run.
• Automated lint and format enforcement integrated into GitHub Actions CI workflows.
• Pre-commit hooks added to automatically run lint and format on staged files.
• Existing codebase cleaned up incrementally to comply with new rules.
• No lint or format errors remain on the main branch after merge.
• Documentation updated with detailed contributing guidelines covering linting and formatting.
• CI fails and blocks merges if lint or format checks fail.
• Performance impact assessed and documented with mitigation if necessary.

---

🧪 Testing Requirements

• Run full lint and format checks locally and verify zero errors/warnings.
• Commit code violating linting rules and verify pre-commit hook blocks the commit.
• Create PR with lint/format violations and verify CI pipeline fails accordingly.
• Test on different OS/dev environments to ensure consistent behavior.
• Validate no regression in existing tests or runtime behavior.

---

📚 Documentation Updates

• Add or update CONTRIBUTING.md with:
  • Linting and formatting expectations and rules summary
  • How to run lint/format commands manually
  • Explanation of automated pre-commit hooks and CI enforcement
  • Troubleshooting common linting errors
• Optionally update README.md with badge and brief note on code quality standards.
• Document configuration files (.biomerc.json or equivalents) inline with comments for clarity.

---

⚠️ Potential Challenges & Risks

• Overly strict linting rules may frustrate contributors, slowing development; balance strictness with pragmatism.
• Large number of style fixes in one go can lead to massive diffs, complicating reviews; incremental fixes preferred.
• Pre-commit hooks can slow down commits if not optimized; consider running on staged files only.
• Ensuring compatibility of linting tools with Astro syntax and latest TypeScript features.
• CI pipeline performance degradation due to expensive lint/format steps; caching or parallelization may be needed.
