Function-Based API FAQ

Is Sprig's API the Vue Composition API?

No. Sprig has signal, computed, effect, createRoot, and onCleanup, but does not implement Vue's Composition API or its lifecycle hooks.

Is there a watch() function?

No separate watcher API is provided. Use effect() to track values read during execution; it runs immediately and returns a stop function.

Can TypeScript be used?

JavaScript remains the supported .sprig script language. TypeScript consumers can use the package's public declaration files in their surrounding application code.
