Reusability

Reusable Sprig code can be packaged as ordinary JavaScript functions, imported .sprig components, or small modules that expose state and helper functions. There is no global plugin/component registry requirement.

Use a component when a unit owns markup and DOM behavior. Use a plain JavaScript helper when only logic is shared. Signals and stores are the reactive primitives; props and slots are the component composition mechanisms. See Composables, Components Basics, and State Management.
