963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

toRefs
Extended toRefs that also accepts refs of an object.
Usage
import { toRefs } from '@vueuse/core';
import { reactive, ref } from 'vue';
const objRef = ref({ a: 'a', b: 0 });
const arrRef = ref(['a', 0]);
const { a, b } = toRefs(objRef);
const [a, b] = toRefs(arrRef);
const obj = reactive({ a: 'a', b: 0 });
const arr = reactive(['a', 0]);
const { a, b } = toRefs(obj);
const [a, b] = toRefs(arr);
Use-cases
Destructuring a props object
<script lang="ts">
import { toRefs, useVModel } from '@vueuse/core';
export default {
setup(props) {
const refs = toRefs(useVModel(props, 'data'));
console.log(refs.a.value); // props.data.a
refs.a.value = 'a'; // emit('update:data', { ...props.data, a: 'a' })
return { ...refs };
},
};
</script>
<template>
<div>
<input v-model="a" type="text" />
<input v-model="b" type="text" />
</div>
</template>
