Nikki Siapno Explains What Makes APIs RESTful
Nikki Siapno, an Engineering Manager at Canva and founder of Level Up Coding, recently highlighted the key principles that make an API RESTful, emphasizing the importance of this architectural style in developing scalable and high-performing web-based applications. According to Nikki, RESTful APIs should maintain statelessness, meaning no user information is stored between requests. They should operate under a separation of concerns, ensuring that client and server functions are independent.
Additionally, responses should be cacheable to enhance performance, and the interfaces must be consistent, utilizing standard HTTP methods such as GET, POST, and DELETE. REST also focuses on resource-based communication, identifying resources through unique URIs and supporting standard media types like JSON, XML, or plain text for responses. Nikki’s discussion, supported by Postman to keep educational content freely available, underscores REST’s role in fostering stable and efficient application development.
