Update the NEXTDEVKIT Codebase

Keeping your NEXTDEVKIT project up-to-date with the latest features and improvements is crucial for maintaining security, performance, and accessing new functionality. This guide will walk you through the various methods to update your codebase safely and efficiently.

⚠️ Important Considerations

While updating your codebase to the latest version is possible, it's important to note that:

🎨 Customizations Impact Complexity: The more customizations you make, the more complex the update process becomes
🔄 Git-Based Updates: Updates involve rebasing your custom code on top of the latest NEXTDEVKIT code
⚙️ Merge Conflicts: You may need to resolve merge conflicts carefully
🛡️ Testing Required: Always test thoroughly after updates

Understanding these considerations will help you plan your update strategy and avoid potential issues.

🚀 Before You Start

Prerequisites Checklist

Before beginning any update process, ensure you have:

🧹 Clean Git Repository: No uncommitted changes
📋 Backup Current State: Create a backup branch
📝 Document Customizations: List all custom changes
🧪 Test Environment: Ensure tests pass
📊 Dependencies: Check for breaking changes

Backup Your Work

Creating a backup is essential before any major update:

# Create a backup branch
git checkout -b backup-before-update

# Push backup to remote
git push origin backup-before-update

# Return to main branch
git checkout main

This backup ensures you can always return to your working state if something goes wrong during the update process.

🔄 Update Methods

Method 1: Git Merge (Recommended for Safety)

This approach is safer and provides clear merge points in your git history. It's ideal for teams and production environments.

# 1. Add the upstream remote if you haven't already
git remote add upstream https://github.com/nextdevkit/nextdevkit.git

# 2. Fetch the latest changes
git fetch upstream

# 3. Create a new branch for the update
git checkout -b update-nextdevkit

# 4. Merge the changes (resolve conflicts if necessary)
git merge upstream/main

# 5. Resolve any merge conflicts
# Edit files to resolve conflicts, then:
git add .
git commit -m "Resolve merge conflicts during update"

# 6. Test the updated code
npm install
npm run build
npm run lint
npm run test

# 7. Merge back to main if everything works
git checkout main
git merge update-nextdevkit

Benefits of Git Merge:

Preserves the complete history of changes
Easier to understand what was merged
Safer for collaborative environments
Can be easily reverted if needed

Method 2: Git Rebase (For Clean History)

This approach creates a cleaner linear history but requires more Git experience. Use this if you prefer a clean commit history.

# 1. Add the upstream remote
git remote add upstream https://github.com/nextdevkit/nextdevkit.git

# 2. Fetch and rebase
git fetch upstream
git rebase upstream/main

# 3. Resolve conflicts if they occur
# For each conflict:
# - Edit the conflicting files
# - Stage the resolved files: git add <file>
# - Continue rebase: git rebase --continue

# 4. Force push (if needed)
git push --force-with-lease origin main

Benefits of Git Rebase:

Creates a linear, clean history
Makes it appear as if your changes were made on top of the latest code
Easier to follow the project timeline
No merge commits cluttering the history

Method 3: Manual Update

If you prefer to update manually or didn't use Git initially, follow these steps:

📥 Download the latest NEXTDEVKIT version
📋 Compare your customized files with the new version
🔄 Apply changes selectively, focusing on:
- package.json for dependency updates
- Configuration files like next.config.ts
- Core functionality in src/lib and src/components
- Database migrations in drizzle/

When to Use Manual Updates:

You didn't initialize your project with Git
You have extensive customizations
You want full control over what gets updated
You're working on a fork with significant changes

📦 Dependency Updates

Update All Dependencies

Keep your dependencies current with the latest security patches and features:

pnpm update

Update Specific Dependencies

For more control, update specific packages:

# Update Next.js
pnpm install next@latest

# Update Drizzle ORM
pnpm install drizzle-orm@latest drizzle-kit@latest

# Update Better Auth
pnpm install better-auth@latest

# Update UI components
pnpm install @radix-ui/react-*@latest

Check for Breaking Changes

Before updating, always check the changelog and migration guides:

Next.js: Check the Next.js upgrade guide
Drizzle ORM: Review Drizzle migration docs
Better Auth: Check the Better Auth changelog

🗄️ Database Schema Updates

When updates include database schema changes, handle them carefully:

Check Migration Files

# Check for new migration files
ls -la drizzle/

# Review migration changes
cat drizzle/0003_new_migration.sql

Apply Migrations

# Production environment
pnpm run db:migrate

# Open Drizzle Studio to verify
pnpm run db:studio

Important Database Considerations:

Always backup your database before applying migrations
Test migrations in a staging environment first
Review migration files to understand what changes are being made
Consider downtime requirements for production deployments

🧪 Testing After Updates

After completing your update, thorough testing is essential:

Run All Tests

# Run unit tests
pnpm run test

# Run integration tests
pnpm run test:integration

# Run end-to-end tests
pnpm run test:e2e

Manual Testing Checklist

🔐 Authentication: Test login/logout functionality
💳 Payment Processing: Verify Stripe integration
📧 Email System: Test email sending
🎨 UI Components: Check for visual regressions
📱 Responsive Design: Test on different screen sizes
🌐 Internationalization: Verify language switching

🚨 Troubleshooting Common Issues

Merge Conflicts

When encountering merge conflicts:

Identify the conflict: Look for <<<<<<<, =======, and >>>>>>> markers
Understand both versions: Review what changed in both your code and the upstream
Choose the best approach: Keep your changes, accept upstream, or combine both
Test thoroughly: Ensure the resolution works correctly

Dependency Conflicts

If you encounter dependency issues:

# Clear node_modules and reinstall
rm -rf node_modules pnpm-lock.yaml
pnpm install

# Check for peer dependency issues
pnpm install --check-peer-deps

Build Errors

If the build fails after updating:

Check TypeScript errors: Run pnpm run type-check
Update TypeScript: Ensure you're using a compatible version
Check configuration files: Verify next.config.ts and tsconfig.json
Review breaking changes: Check the changelog for breaking changes

📋 Best Practices

Regular Updates
