Bridging the Gap between Spring and Angular with OpenAPI

Spring and Angular are popular choices for web applications, yet a notable gap often exists between them. Discrepancies in types and DTOs between Spring Controllers and Angular applications can lead to unforeseen issues.

Enter OpenAPI, a powerful solution that allows us to define APIs using a YAML file. OpenAPI then automatically generates Spring Controllers and Java classes, ensuring consistency and alignment. This tool also proves valuable for existing APIs, as it analyzes Spring to generate specifications on-the-fly.

Join this hands-on webinar to explore both options in depth. Learn how to customize OpenAPI for your specific needs and tackle advanced scenarios like APIs for file uploading and downloading.
