Building a Cloud-Native RESTful API with Ballerina and MySQL

Description and use

A minimal REST API for a bookstore was built with Ballerina, featuring secure MySQL queries and reduced boilerplate, illustrating cloud-native integration benefits.

Problem

Traditional languages require repetitive boilerplate for integration code in distributed architectures.

Outcome

The project demonstrates a minimal-boilerplate, type-safe REST API with secure database interactions, showcasing Ballerina’s suitability for cloud-native integration.

Workflow

• Define data models in types.bal
• Create MySQL client in db.bal using ballerinax/mysql
• Implement CRUD resources in service.bal with minimal boilerplate
• Externalize credentials in Config.toml
• Run the service on http:Listener(8080)
• Test endpoints for CRUD functionality
