What technology does Liferay use to facilitate communication between the frontend and backend?

Liferay primarily utilizes RESTful APIs to facilitate communication between the frontend and backend. RESTful APIs are known for their simplicity and efficiency in handling requests and responses over HTTP, making them ideal for web applications. They allow for stateless communication, which fits well within the architecture of modern web applications, enabling Liferay to retrieve and send data seamlessly between the server and the client-side applications.

RESTful APIs also support various formats, including JSON, which is widely used in frontend frameworks for its lightweight and easy-to-parse structure. This compatibility is especially beneficial for developing dynamic and responsive user interfaces in Liferay, allowing developers to integrate data and functionalities easily without cumbersome protocols.

While other options like GraphQL are gaining popularity for specific use cases, RESTful APIs remain the backbone of many web applications, including Liferay, due to their robustness and widespread industry adoption. Other options listed, such as sockets and SOAP APIs, pertain to different interaction paradigms that are not the primary means of communication in the context of Liferay's architecture.
