Building, specifying, and testing APIs with microservices
Who is this presentation for?
- Developers and architects
James Gough, Padma Sridhar, and Matthew Auburn walk you through the creation of a very simple task list API.
- Create microservices using Spring Boot, which exposes an API (and prove that’s not the hard part, with options offered for non-Java developers)
- Use either Pact or Spring Cloud Contract to test and progress the API with new features
- Discover how to use OpenAPI to specify an API and the balance between developing APIs with specification first or contract driven
- Use a specification to allow your API to be versioned and use semantic versioning to ensure that components in your architecture remain decoupled and free to move without breaking consumers
- Explore the reasons for an API gateway, why they’re architecturally important, and the concepts of a service mesh in the context of developing an API program
Materials or downloads needed in advance
- A WiFi-enabled laptop (prerequisites here)
What you'll learn
- Understand that building an API is very simple and that testing and ensuring API compatibility is key to loosely coupled services
- Learn the importance of OpenAPI Specifications and whether they're incidental or crafted
- Discover how to use semantic versioning to ensure compatibility of services
- Gain an introduction to gateways and microservices
