PubNub has announced two significant updates: the renaming of PubNub BLOCKS to Functions, and the introduction of webhook integration with Endpoints. Functions, a serverless compute service, facilitates the execution of business logic on messages as they stream through PubNub, allowing developers to easily build and operate real-time applications without managing server infrastructure. It deploys rapidly, scales automatically, and operates with minimal latency on the PubNub Data Stream Network. The new Endpoints feature enables Functions to be accessed by any system capable of making an HTTP request, simplifying the process of creating webhooks and supporting functionalities such as message transformation, third-party service integration, and advanced chat capabilities. These enhancements are designed to help developers create large-scale social applications, online games, IoT use cases, and more, with comprehensive support for secure REST endpoints and stateful data management.
