Follow Alerts Get Their Own Bespoke Presentation

Giving Individual Alerts Their Identity Back

The Global Alert Framework had deliberately moved shared behaviour out of individual alerts, but that did not mean every presentation needed to look the same. With routing, lifecycle and ownership becoming central responsibilities, CRESA could start giving individual event types their own experiences without rebuilding the machinery underneath them every time.

Follow became the first alert to take advantage of that approach through a new bespoke single-alert presentation.

A Reusable Single-Alert Runtime

Rather than building the Follow experience as another isolated animation, development introduced a reusable single-alert runtime and renderer system. This provided a common structure that bespoke presentations could use while still allowing each alert type to define its own visual treatment.

The Follow presentation moved through a deliberate sequence of mount, intro, reveal, hold, outro and complete, with animation completion driving the lifecycle forward instead of relying entirely on disconnected timers.

Designed to Finish Cleanly

A presentation is only useful if CRESA also knows exactly when it has finished. The new runtime connected visual progression with lifecycle cleanup so the framework could release the alert properly once its outro completed.

Practical details were handled as part of the presentation too, including safely truncating unusually long usernames rather than allowing them to damage the layout.

Bespoke Without Becoming Isolated

The important part was how Follow behaved when the rest of the alert system became involved. It could hand activity into stacked presentation when additional alerts arrived, respect Quiet ownership and cope with higher-priority interruption without creating duplicate queues or requiring the browser presentation to reload.

Follow now had its own identity again, but unlike CRESA's earliest bespoke alert experiments, that identity was sitting on top of a shared presentation architecture designed for whatever came next.
