# Dependency Update & Deprecation Fix

This command updates all dependencies in both frontend (npm) and backend (uv), fixes deprecations, and ensures zero warnings.

## Step 1: Check for Updates

### Backend (Python with uv):
```bash
cd backend
uv lock --upgrade
uv tree --outdated

Frontend (JavaScript with npm):

cd frontend
npm outdated

Step 2: Update Dependencies

Backend:

cd backend
uv sync --upgrade --all-extras

Frontend:

cd frontend
npm update
npm audit fix

Step 3: Check for Deprecations & Warnings

Run installation and READ ALL OUTPUT CAREFULLY:

Backend:

cd backend
rm -rf .venv
uv sync --all-extras

Look for:

• Deprecation warnings
• Security vulnerabilities
• Package conflicts
• Python version warnings

Frontend:

cd frontend
rm -rf node_modules package-lock.json .next
npm install

Look for:

• Deprecation warnings (npm WARN deprecated)
• Security vulnerabilities (npm audit)
• Peer dependency warnings
• Next.js/React version conflicts

Step 4: Fix All Issues

ZERO-TOLERANCE POLICY: Fix ALL warnings and deprecations before proceeding.

For each warning:

1. Research the recommended replacement
2. Update dependencies or code
3. Re-run installation
4. Verify warning is gone

Common fixes:

• Update deprecated packages to latest versions
• Replace deprecated APIs with new ones
• Fix peer dependency mismatches
• Update breaking changes per migration guides

Step 5: Run Quality Checks

Backend:

cd backend
uv run ruff check app
uv run mypy app
uv run pytest

Fix all errors before proceeding.

Frontend:

cd frontend
npm run lint
npm run type-check
npm run build

Fix all errors before proceeding.

Step 6: Verify Clean Install & Zero Warnings

Backend:

cd backend
rm -rf .venv
uv sync --all-extras 2>&1 | tee install-log.txt

Verify:

• ✅ No deprecation warnings
• ✅ No security vulnerabilities
• ✅ All packages resolve
• ✅ Clean output

Frontend:

cd frontend
rm -rf node_modules package-lock.json .next
npm install 2>&1 | tee install-log.txt

Verify:

• ✅ 0 vulnerabilities
• ✅ No deprecation warnings
• ✅ No peer dependency warnings
• ✅ Clean install

Step 7: Test Servers

Start both servers and verify they run without warnings:

Backend:

cd backend
uv run uvicorn app.main:app --reload

Check for runtime warnings.

Frontend:

cd frontend
npm run dev

Check for:

• No Fast Refresh errors
• No compilation warnings
• No runtime warnings

Step 8: Commit Changes

Once everything is clean:

git add backend/pyproject.toml backend/uv.lock frontend/package.json frontend/package-lock.json
git commit -m "chore: update dependencies and fix deprecations

- Updated all backend dependencies (uv)
- Updated all frontend dependencies (npm)
- Fixed all deprecation warnings
- Resolved security vulnerabilities
- Verified zero warnings on fresh install
"
git push

Success Criteria

• ✅ All dependencies updated
• ✅ Zero deprecation warnings (backend + frontend)
• ✅ Zero security vulnerabilities
• ✅ All quality checks passing (lint, typecheck, tests)
• ✅ Clean install with no warnings
• ✅ Servers start without warnings
• ✅ Changes committed and pushed

IMPORTANT: Do not mark complete until ALL criteria are met! ```
