Web Development with Rust Training

Build production-grade web services in Rust with this hands-on 3-day training. Learn both Actix Web and Axum frameworks side by side, covering request handling, middleware, authentication, database integration with SQLx, and deployment strategies. By the end, you will have built and deployed a complete REST API backed by PostgreSQL.

Training Details

After completing this training, participants will be able to:

• Build REST APIs with both Actix Web and Axum
• Implement middleware for logging, CORS, and authentication
• Integrate PostgreSQL using SQLx with compile-time query checking
• Handle JSON serialization and deserialization with serde
• Write integration tests for web endpoints
• Deploy Rust web services with Docker
