Often, we need to convert domain model to DTO (Data transfer object) and vice versa. This is necessary when transferring data to frontend or remote interfaces. Dealing with complex mappings manually becomes cumbersome and may result in errors.
Integrating Backend APIs manually can be time consuming and error-prone. Hence, Swagger comes into picture. Swagger is the most popular framework to generate and consume OpenAPI specification. The tool greatly relieves the burden of documenting and interacting with APIs.
