BUILDING A TOAST COMPONENT

Summary from the TLDR Dev newsletter

Sonner was a library released in 2023 that quickly became the default toast component for shadcn/ui, despite a crowded market. Its success was due to its well-implemented stacking animations achieved with interruptible CSS transitions, and intuitive functionalities like momentum-based swipe-to-dismiss and expandable toast displays. The developer experience was also unique, with interactive documentation, a simple, hook-free API using the Observer Pattern, and a promise API for managing toast states.
