Detailed Agenda

Day 1: REST API Development

Module 1: HTTP Server Foundations

net/http package deep dive
ServeMux and handler patterns
Request parsing and response writing
JSON encoding and decoding
Hands-on: Build a CRUD API with net/http

Module 2: Routing and Middleware

Popular routers (chi, gorilla/mux, gin)
Middleware patterns and chaining
Logging, recovery, and CORS middleware
Request validation and error responses
Hands-on: Refactor to chi router with middleware stack

Module 3: Authentication and Authorization

JWT token generation and validation
OAuth2 integration patterns
Role-based access control middleware
API key authentication
Hands-on: Add JWT authentication to the API

Day 2: Database Integration and gRPC

Module 4: Database Access

database/sql package and connection pooling
Query patterns and prepared statements
Migrations with golang-migrate
Working with sqlx and GORM
Hands-on: Add PostgreSQL persistence layer

Module 5: gRPC Services

Protocol Buffers and service definitions
Unary and streaming RPCs
gRPC interceptors and metadata
Error handling in gRPC
Hands-on: Build a gRPC service with streaming

Module 6: API Design Best Practices

RESTful resource design
Pagination, filtering, and sorting
Versioning strategies
API documentation with OpenAPI/Swagger
Hands-on: Design and document a complete API

Day 3: Testing, Deployment, and Production Readiness

Module 7: API Testing

Unit testing HTTP handlers
httptest package for integration tests
Table-driven API tests
Mocking dependencies with interfaces
Hands-on: Write comprehensive test suites

Module 8: Production Patterns

Configuration management (env vars, files, flags)
Structured logging with slog
Health check endpoints and readiness probes
Graceful shutdown and signal handling
Hands-on: Add production instrumentation

Module 9: Deployment

Multi-stage Docker builds for Go
Container-optimized binaries (static linking, scratch images)
Kubernetes deployment manifests
CI/CD pipeline for Go services
Hands-on: Containerize and deploy the service
