9 Must-Know REST API Design Principles for Developers

Learn the best practices for designing REST APIs with Java in this comprehensive guide. From correctly using HTTP methods like GET, POST, PUT, and DELETE to structuring resources with clean URIs and hierarchical paths, we’ll cover it all. Discover how to use HTTP status codes, handle errors with clarity, validate requests using Hibernate Validator, and implement API versioning for backward compatibility. We also dive into managing large data sets with pagination, filtering, and sorting, and how to enhance API usability with HATEOAS (Hypermedia). Finally, strengthen your API security with HTTPS, OAuth 2.0, and JWT using Spring Security. https://www.linkedin.com/in/bytemonk/ Timestamps 00:00 Introduction – REST APIs: Lightweight, Scalable, and Easy to Use 00:22 HTTP Methods – Correct Usage for Actions Like GET, POST, PUT, PATCH, DELETE 01:10 Resource Design – Using Nouns and Hierarchical URIs Effectively 02:30 HTTP Status Codes – Communicating Outcomes with Standards 03:35 Error Handling – Descriptive and Consistent Responses in Spring 04:17 Validation – Using Hibernate Validator for Clean Input 05:02 API Versioning – URI vs Header Versioning for Backward Compatibility 06:20 Pagination, Filtering, Sorting – Managing Large Data Sets Efficiently 7:45 HATEOAS – Enhancing Discoverability with Hypermedia Links 9:08 Security –HTTPS, Authentication, and Authorization https://www.youtube.com/playlist?list=PLJq-63ZRPdBt423WbyAD1YZO0Ljo1pzvY https://www.youtube.com/playlist?list=PLJq-63ZRPdBssWTtcUlbngD_O5HaxXu6k https://www.youtube.com/playlist?list=PLJq-63ZRPdBu38EjXRXzyPat3sYMHbIWU https://www.youtube.com/playlist?list=PLJq-63ZRPdBuo5zjv9bPNLIks4tfd0Pui https://www.youtube.com/playlist?list=PLJq-63ZRPdBsPWE24vdpmgeRFMRQyjvvj https://www.youtube.com/playlist?list=PLJq-63ZRPdBslxJd-ZT12BNBDqGZgFo58 AWS Certification: AWS Certified Cloud Practioner: https://youtu.be/wF1pldkQrOY AWS Certified Solution Architect Associate: https://youtu.be/GzomXNLFgkk AWS Certified Solution Architect Professional: https://youtu.be/KFZrBxSA9tI #rest #api #systemdesign
