Environment Configuration

Now that your repositories are set up, let's install project dependencies and configure your development environment. This final step ensures everything is ready for active development.

Overview​

In this section, we'll:

  • Verify your complete development environment setup
  • Test that all system tools are properly configured
  • Validate that repositories are ready for development
  • Complete the final setup validation

Step 1: System Tools Verification​

Let's verify that all required tools are properly installed and configured:

terminal
# Check all required tools
echo "=== System Tools Verification ==="
git --version
node --version
npm --version
wrangler --version

Expected output example:

terminal
=== System Tools Verification ===
git version 2.39.0
v18.17.0
9.6.7
⛅️ wrangler 3.15.0

System tools verification

Step 2: Repository Structure Validation​

Verify that your repositories are properly set up:

terminal
# Check repository structure
echo "=== Repository Structure ==="
ls -la ~/projects/

You should see:

  • blazenote-frontend/ directory
  • blazenote-backend/ directory

Check that you're on the correct branches:

terminal
# Check frontend branch
cd ~/projects/blazenote-frontend && git branch
echo "Frontend branch: $(git branch --show-current)"

# Check backend branch
cd ~/projects/blazenote-backend && git branch
echo "Backend branch: $(git branch --show-current)"

Expected output:

terminal
Frontend branch: starter
Backend branch: starter

Step 3: Final Environment Validation​

Let's run a comprehensive check to ensure everything is working:

System Tools Verification​

terminal
# Check all required tools
echo "=== System Tools ==="
git --version
node --version
npm --version
wrangler --version

Final verification

Environment Configuration Checklist​

Before proceeding to development, verify:

System Tools​

  • Git installed and configured with user information
  • Node.js (v18+) installed and accessible
  • npm package manager working
  • Wrangler CLI installed and working

Repository Setup​

  • Both repositories cloned successfully
  • Currently on starter branch in both projects
  • Can navigate between project directories
  • Git remote origins properly configured

Account Authentication​

  • GitHub account configured and accessible
  • Cloudflare account created and accessible
  • Wrangler CLI authenticated with Cloudflare
  • All accounts properly linked

Development Readiness​

  • All tools respond without errors
  • Project directories contain expected files
  • Ready to begin deployment modules
  • All prerequisites completed

Troubleshooting Common Issues​

Dependency Installation Problems​

"npm install" fails:

terminal
# Clear npm cache
npm cache clean --force

# Delete node_modules and try again
rm -rf node_modules package-lock.json
npm install

npm reinstall

Permission errors:

terminal
# Fix npm permissions (Unix/macOS)
sudo chown -R $(whoami) ~/.npm

# Or use a different npm directory
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH

Development Server Issues​

Port already in use:

terminal
# Find and kill process using port 5173
lsof -ti:5173 | xargs kill -9

# Or use a different port
npm run dev -- --port 3000

Module not found errors:

  • Ensure you're in the correct directory
  • Run npm install again
  • Check that node_modules folder exists

TypeScript Errors​

Type checking fails:

terminal
# Regenerate TypeScript declarations
npm run types

# Check TypeScript version
npx tsc --version

What's Next?​

Congratulations! 🎉 Your development environment is now configured and ready.

You have successfully:

  • Installed all development tools
  • Set up GitHub and Cloudflare accounts
  • Forked and cloned project repositories
  • Verified your complete system setup
  • Authenticated with all necessary services

Next Steps:

  • Begin Module 1: Frontend Deployment - Install frontend dependencies and deploy
  • Continue with Backend Deployment - Install backend dependencies and deploy
  • Start building your note-taking application on Cloudflare's global network

Development Workflow​

Typical workflow after completing deployment modules:

  1. Navigate to your project directory
  2. Pull latest changes: git pull origin starter
  3. Install/update dependencies: npm install
  4. Start development server: npm run dev
  5. Make your changes
  6. Test locally
  7. Deploy using npm run deploy or npx wrangler deploy via Cloudflare Workers
