Description
Vue version
3.5.16
Link to minimal reproduction
Steps to reproduce
import { computed, ref } from "vue";
// Inconsistent excess property checking: ref<T>() errors, computed<T>() doesn't
const withRef = ref<{ a: string }>({
a: "hello",
b: "world", // Error
});
const withComputed = computed<{ a: string }>(() => ({
a: "hello",
b: "world", // No error
}));What is expected?
TypeScript should raise Object literal may only specify known properties, and 'b' does not exist in type '{ a: string; }'. ts(2353) for withComputed, as it does for withRef.
What is actually happening?
TypeScript does not raise any error for withComputed, though it definitely should.
If, for some technical reason, type checking cannot be enforced with computed in the same way it is with ref, this behavior should be documented.
