To configure strict template type checking in Vue 3, enable the strictTemplates option within vueCompilerOptions. This ensures Volar validates component props, events, and unknown elements in templates.

The best way to define types for Vue 3 component props and emits is by using the defineProps and defineEmits compiler macros with TypeScript helper types. This derives explicit prop and event types for Volar assistance.

To forward attributes safely in Vue wrapper components, apply fallthroughAttributes best practices to maintain type safety across wrappers. This prevents inconsistent typing and runtime errors during refactoring.

Volar shows type errors for unknown components because template type checking is enabled via vueCompilerOptions. Using checkUnknownComponents validates template elements against your TypeScript definitions.

Yes, you can use vue-tsc to check Vue 3 component template types. It leverages Volar configurations like strictTemplates to validate props, emits, and unknown components during compilation.
