Learn - OpenAPI Spec
OpenAPI helps speed up API development. You Define, mock, and test REST APIs using a single truth/specification. Ideal for dev and QA teams adopting contract-first workflows.
Deeply nested schemas can become unwieldy and hard to maintain. For instance, a User object containing an Address object, which in turn contains a Location object, can quickly become complex.
Why it matters: Simplifying schemas enhances readability and maintainability, making it easier for both developers and consumers to understand and work with the API.
Defining schemas, parameters, and responses inline repeatedly instead of using the components section leads to redundancy and potential inconsistencies.
Why it matters: Leveraging components promotes reusability and consistency across the API specification.
Logically group your APIs into smaller, domain-specific specs — like auth.yaml, payment.yaml, orders.yaml.
Use tags in OpenAPI to group related endpoints (like Order, Customer, Admin) even within a single file if needed.
