Walkthrough

Adds CI workflow, reinstates and expands .gitignore entries, adds MIT LICENSE, updates package.json metadata, removes comments from Jest config, and adds badges to README. No application logic changes.

Changes

Cohort / File(s)	Summary
CI workflow \.github/workflows/ci.yml	New GitHub Actions workflow named "CI": runs on push to main and PRs, uses ubuntu-latest, sets up Node from .nvmrc, caches npm, installs deps, runs tests with coverage, uploads to Codecov, and prints recent commits. Concurrency and 30m timeout configured.
Ignore rules \.gitignore	Restores Next.js/node_modules ignore rules, preserves .env, adds coverage ignore and SQLite data patterns (/data/*.db, /data/*.db-wal, /data/*.db-shm), and restructures cursor-related exclusions.
License & docs LICENSE, README\.md	Adds MIT LICENSE with 2025 copyright; inserts CI and CodeRabbit PR Reviews badges into README.md.
Package metadata package\.json	Adds descriptive metadata: description, author, license, homepage, bugs, repository, and keywords. No script or dependency changes.
Test config cleanup jest\.config\.ts	Removed inline comments and an empty comment line; no functional configuration changes.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Review .github/workflows/ci.yml for correct action versions, secrets usage (CODECOV_TOKEN), cache key logic, and concurrency semantics.
• Verify .gitignore patterns against repo layout so required files aren't excluded.
• Confirm package.json metadata fields (repository, bugs URL, homepage) are accurate.

Poem

🐰 I hopped through commits, a tiny cheer,
CI lights glowing, tests draw near.
License stitched, ignores swept clean,
Badges sparkle—what a scene! 🎉 🥕

README.md (1)

5-6: Badges properly positioned and formatted.

The CI and CodeRabbit badges are correctly added after the project description and align with the new workflow infrastructure being introduced in this PR.

LICENSE (1)

1-20: MIT License properly added with correct copyright holder.

The LICENSE file is complete, standard, and correctly identifies Serghei Iakovlev as the copyright holder. Aligns with the "license": "MIT" field in package.json.

jest.config.ts (1)

10-16: Comment cleanup maintains clarity.

Removing inline comments from the Jest configuration is appropriate here since the config values are self-documenting. Config structure and imports remain correct.

.gitignore (1)

1-27: Ignore patterns properly structured with clear organization.

The .gitignore updates are comprehensive and well-documented. SQLite WAL/SHM files are correctly included to prevent version control issues, and the coverage directory addition aligns with the CI workflow. The .cursor rules exclusion pattern allows team development tooling to be preserved.

package.json (1)

5-18: Package metadata fields complete and consistent.

The added metadata (description, author, license, homepage, bugs, repository, keywords) follows npm package.json conventions and is consistent with the LICENSE file and project documentation. JSON structure is correct.

.github/workflows/ci.yml (3)

65-67: Clarify intent of commented-out cache conditional.

Lines 65-66 comment out the cache-hit conditional if: steps.npm-cache.outputs.cache-hit != 'true', with a note saying "Disable cache for now to test the workflow." This causes npm ci --include=dev to run unconditionally, even when the npm cache is fresh.

If this is intended as a temporary debug measure, consider whether it should be enabled before merging. If caching should remain disabled permanently, remove the commented lines and the comment for clarity.

---

69-78: Ensure codecov integration is properly configured.

The workflow uploads coverage to codecov with strict error handling (fail_ci_if_error: true). Verify that:

1. The CODECOV_TOKEN secret has been added to the GitHub repository settings
2. The codecov service is correctly linked to your repository
3. Coverage upload permissions are properly configured in codecov

Without these prerequisites, the workflow will fail on the codecov step despite successful test runs.

---

47-47: The .nvmrc file exists in the repository root and contains a valid Node.js version (24). The node-version-file: '.nvmrc' configuration will work correctly without issues.

.github/workflows/ci.yml (1)

72-78: Verify CODECOV_TOKEN secret is configured in repository settings.

The workflow uploads coverage to Codecov with fail_ci_if_error: true (line 74), which means the workflow will fail if the CODECOV_TOKEN secret is not set in GitHub repository settings or if the upload fails. Verify that this secret has been properly configured; otherwise, the CI workflow will fail at this step on every run.

Alternatively, if Codecov integration is not yet ready, consider setting fail_ci_if_error: false to allow the workflow to continue even if the upload fails.
