Spring Boot 3 Portfolio Project

A short, self-contained project: a weather REST API that wraps a third party service. Small enough to finish in an evening, real enough to put on a CV.

Calling somebody else's API is most of what backend work actually involves, so this covers the parts that matter: handling the response, dealing with the upstream being slow or wrong, and not leaking its shape into your own.

What you build

A weather REST API built on top of a third party weather service.

What you learn

• Consume a third party HTTP API from Spring Boot
• Map an external response onto your own domain model
• Handle upstream errors and timeouts properly
• Keep API keys out of your source tree
• Cache responses you should not be fetching twice

Before you start

• Basic Spring Boot: controllers and services
