REST APIs Course Overview REST APIs are a staple for developers the world over. Whether it's to provide a web app with access to server data or to facilitate comms between microservices,REST APIs have exploded in popularity due to their simplicity and flexibility. This course comprises sessions dealing with prerequisite topics including HTTP and JSON,core REST theory,the building of REST services and clients,REST API configuration including caching and HATEOAS,and yet more REST theory including the Richardson Maturity Model,the n+1 problem,and authentication techniques. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered. Delegates have the option of coding in either Java,Python,or JavaScript.
