Pusher has introduced Serverless Functions for its Channels platform, allowing developers to modify, filter, change, and reroute real-time events without managing their own infrastructure. These functions, which are hosted on Pusher's infrastructure, can be deployed via the Pusher CLI and are triggered by client or presence channel events. This feature offers faster deployment, scalability, and optimized infrastructure management, freeing developers from server maintenance tasks. The functions are customizable, can automate business logic, and are designed for high availability across multiple zones, all while being cost-efficient by integrating into existing Channels plans. Use cases include logging, integration with third-party systems, real-time data analysis, profanity filtering, and message translation, among others. Pusher encourages developers to explore and share their implementations with the community and offers resources to get started immediately with a free sandbox account.
