Prerequisites
Completed Previous Tutorials
Strong understanding of Gemini CLI basics, codebase exploration, and interactive development.
Advanced Development Experience
Experience with version control, deployment processes, and system administration concepts.
Code Migration and Modernization
Technology Migration
Use Gemini CLI to help migrate codebases to newer technologies, frameworks, or language versions:
Migration Scenarios:
Language version upgrade:
> Help me migrate this codebase to the latest version of Java. Start with a plan.Framework migration:
> Create a migration plan to move this Angular app to React.Database migration:
> Help me migrate from MySQL to PostgreSQL, including schema changes.Step-by-Step Migration Process
Gemini CLI can help you create comprehensive migration plans and execute them systematically:
Migration Workflow:
1. Assessment
Get a comprehensive overview of migration requirements
> Analyze this codebase and identify what needs to be migrated2. Planning
Develop a structured approach to the migration
> Create a detailed migration plan with priorities and dependencies3. Implementation
Execute migration steps with AI assistance
> Help me implement the first phase of the migration plan4. Testing
Ensure functionality is preserved after migration
> Generate tests to verify the migration was successfulSystem Automation and File Operations
File and Media Processing
Automate repetitive file operations and media processing tasks:
Automation Examples:
Image processing:
> Convert all images in this directory to PNG format.File organization:
> Organize my PDF invoices by month and year.Data processing:
> Process these CSV files and generate a summary report.Build and Deployment Automation
Streamline your build processes and deployment workflows:
Deployment Tasks:
CI/CD pipeline setup:
> Create a GitHub Actions workflow for this project.Docker configuration:
> Generate a Dockerfile and docker-compose.yml for this application.Environment setup:
> Create deployment scripts for staging and production environments.Integration Patterns and External Tools
API Integration and Webhooks
Connect your applications with external services and APIs:
Integration Examples:
Third-party API integration:
> Help me integrate the Stripe payment API into this e-commerce app.Webhook implementation:
> Create a webhook handler for GitHub repository events.Data synchronization:
> Set up real-time data sync between our database and external CRM.Monitoring and Analytics Integration
Implement comprehensive monitoring and analytics solutions:
Monitoring Setup:
Application monitoring:
> Implement error tracking and performance monitoring for this app.Custom dashboards:
> Create a real-time dashboard showing key business metrics.Alerting systems:
> Set up automated alerts for system failures and performance issues.Complex Workflow Orchestration
Multi-Step Automation Workflows
Design and implement complex workflows that combine multiple tools and processes:
Advanced Workflow Examples:
Automated Release Pipeline
> Create an automated release pipeline that runs tests, builds Docker images, updates documentation, and deploys to staging.Combines testing, building, documentation generation, and deployment automation.
Data Processing Pipeline
> Build a pipeline that processes incoming data files, validates them, transforms the data, and updates multiple databases.Orchestrates file processing, validation, transformation, and database operations.
Content Management Workflow
> Automate content publishing: resize images, generate thumbnails, update metadata, and sync to CDN.Combines image processing, metadata management, and content distribution.
Best Practices for Advanced Workflows
🎯 Planning and Design
- Break complex workflows into smaller, testable components
- Design for failure and implement proper error handling
- Document workflow dependencies and requirements
- Plan for monitoring and observability from the start
- Consider security implications at each step
⚡ Implementation and Maintenance
- Test workflows in isolated environments first
- Implement comprehensive logging and monitoring
- Use version control for workflow configurations
- Regularly review and optimize performance
- Maintain clear rollback procedures
Congratulations!
