API First Development With Open API Spring Boot Kotlin

Course Title: API-first Development with Spring Boot & Kotlin Using OpenAPI Specification (Swagger)

Course Headline: Unlock the Full Potential of Your APIs with Spring Boot and Kotlin! 🌟

What Does an API-first Development Approach Mean? API-first is a development philosophy that centers around creating APIs as standalone products, where their interfaces are defined and shared before any code is written. This approach emphasizes the importance of having well-documented and consistent APIs, making them more reliable and easier to maintain over time. By designing APIs around an OpenAPI specification, teams ensure that their APIs are understandable and can be used by anyone, anywhere.

The Benefits of an API-first Development Approach 🚀 Choosing an API-first approach offers a multitude of advantages for your development process:

• Parallel Development: Teams can work simultaneously on the API's interface and implementation, leading to faster progress.
• Cost Reduction: By focusing on the API contract early, companies save money by avoiding costly changes later in the development lifecycle.
• Speed to Market: An API-first approach allows for quicker iterations and releases, getting your products to market sooner.
• Developer Experience: Well-documented APIs make it easier for developers to understand and use your services, leading to better integrations and partnerships.
• Risk Mitigation: Identifying potential issues early in the development process reduces the risk of significant overhauls or refactoring later on.

APIs as First-Class Citizens 🏗️ In an API-first approach, APIs are treated like products in their own right, which means they need to be planned, organized, and shared within the organization. Adopting this approach requires the use of tools and practices that support it, ensuring that APIs are central to your digital strategy.

What you'll learn: This comprehensive course will guide you through the process of developing APIs using Spring Boot and Kotlin, with a focus on leveraging the OpenAPI specification (Swagger). You'll gain hands-on experience in:

• API First Development with Spring Boot & Kotlin: Discover how to build robust APIs from scratch, following an API-first development methodology.
• OpenAPI Specification: Understand how to design your API using the industry-standard OpenAPI specification, ensuring consistency and understandability across all your APIs.
• Swagger UI Integration: Learn to integrate Swagger UI for interactive documentation of your APIs, making them easier to use and test.
• OpenAPI Spring Generator: Use this tool to automatically generate code from OpenAPI specifications, streamlining the development process.
• Automate Code Generation with Build Tools: Implement build tools like Gradle or Maven to automate the generation of Kotlin code based on your OpenAPI specification.
• OpenAPI - InterfaceOnly Approach: Explore how to define APIs using only the interface definition, without an implementation.
• OpenAPI - Delegate Approach: Learn about delegating the actual logic to backend services while keeping the API contract consistent and up-to-date.
• JPA with Spring Boot & Kotlin: Dive into using Java Persistence API (JPA) for database operations within your Spring Boot & Kotlin applications.
• Spring Boot REST API with OpenAPI in Detail with H2 Database: Combine your knowledge to create a full-fledged REST API with Spring Boot, powered by an H2 in-memory database, and documented using OpenAPI specifications.

Join us on this journey to master the art of building APIs that stand the test of time and scale effectively. Whether you're a seasoned developer or just starting out, this course will equip you with the skills necessary to thrive in an API-centric world! 🚀🐝
