PubNub offers two key features, Functions and Events & Actions, to enhance real-time data handling and integration with third-party systems. Functions allow users to write serverless Node.js code to capture and manipulate events on the PubNub platform, enabling data transformation, re-routing, moderation, and aggregation. In contrast, Events & Actions provides a no-code solution to export real-time data from PubNub to external systems for storage or analysis, utilizing a filtering mechanism for precise data selection. While Functions are ideal for complex event-driven processing and custom business logic, Events & Actions is suited for scenarios involving data export and consolidation. The choice between these tools depends on the specific needs, such as whether real-time data needs to be sent to third parties or if in-depth processing within PubNub is required. PubNub’s flexibility with these features supports a variety of applications, including in-app chats, live events, and data streaming, emphasizing scalability and low latency.
