Modern Web Server with Deno 2 + Hono Deployed to Cloud Run

The Journey

I built a modern web server using Deno 2 and Hono framework, containerized it with Docker, and deployed it to Google Cloud Run through an automated CI/CD pipeline.

Technical Implementation

Development Stack

• Deno 2 runtime for TypeScript execution
• Hono framework for routing and middleware
• Built-in testing capabilities
• TypeScript for type safety

Container Setup

• Multi-stage Docker builds
• Optimized layer caching
• Minimal production image
• Environment configuration

Cloud Infrastructure

• Google Cloud Run for serverless hosting
• Artifact Registry for container images
• IAM role configurations
• Auto-scaling setup

CI/CD Pipeline

• GitHub Actions workflow
• Automated testing
• Container builds
• Cloud Run deployments
