@react-querybuilder/vue

Vue 3 component for complex query building. A port of React Query Builder built on @react-querybuilder/core, producing byte-identical DOM output.

Package name is temporary. The intended name is vue-querybuilder, but npm's automated checks currently reject it as too similar to the existing vue-query-builder. The package ships as @react-querybuilder/vue until that name is available.

Installation

npm install @react-querybuilder/vue

vue@^3.5 is a peer dependency. @react-querybuilder/core is a regular dependency and is re-exported in full, so you never need to depend on it directly.

Quick start

<script setup lang="ts">
import { ref } from 'vue';
import { formatQuery, QueryBuilder, type Field, type RuleGroupType } from '@react-querybuilder/vue';
import '@react-querybuilder/vue/dist/query-builder.css';

const fields: Field[] = [
  { name: 'firstName', label: 'First Name' },
  { name: 'lastName', label: 'Last Name' },
  { name: 'age', label: 'Age', inputType: 'number' },
];

const query = ref<RuleGroupType>({
  combinator: 'and',
  rules: [{ field: 'firstName', operator: 'beginsWith', value: 'Stev' }],
});
</script>

<template>
  <QueryBuilder v-model:query="query" :fields="fields" />
  <pre>{{ formatQuery(query, 'sql') }}</pre>
</template>

Driving the query

Approach	Use when
:default-query	Uncontrolled; the component owns the query.
v-model:query	Idiomatic two-way binding. Preferred.
:query + :on-query-change	Explicit controlled mode.
:manager	External control via a QueryManager instance you own.

v-model:query is sugar for :query plus @update:query. onQueryChange is a callback prop, not an emit, and fires immediately before update:query; the two can be used together.

Veto callbacks — onAddRule, onAddGroup, onRemove, onMoveRule, onMoveGroup, onGroupRule, onGroupGroup — are callback props rather than emits, because a Vue emit cannot return a value and these must be able to cancel or rewrite the pending change.

External control:

<script setup lang="ts">
import { QueryManager, QueryBuilder } from '@react-querybuilder/vue';

const manager = new QueryManager({ combinator: 'and', rules: [] }, { history: true });
const undo = () => manager.undo();
</script>

<template>
  <QueryBuilder :manager="manager" :fields="fields" />
  <button @click="undo">Undo</button>
</template>

Styling

Two prebuilt stylesheets ship in dist: query-builder.css (full) and query-builder-layout.css (structural only). Both are byte-identical to @react-querybuilder/core's. The .scss sources are published alongside them for @use ... with (...) overrides. See Styling.

Examples

• examples/demo — Vite + Vue. Seven field types, standard and independent-combinator queries, every display flag, undo/redo, and live formatQuery output. Aliases the library source, so it hot-reloads with no build step.

  bun install && bun --filter @vue-querybuilder/example-demo dev

• examples/nuxt — Nuxt 4, server-side rendering. Consumes the built dist as a workspace dependency and doubles as the project's SSR gate (ssr-smoke-test.ts, run by bun run test:ssr).

  bun install && bun run build && bun --filter @vue-querybuilder/example-nuxt dev

Non-goals

Drag and drop, UI-framework compatibility packages, expr/datetime UI, async option lists, a Redux store, and deprecated-prop fallbacks are all out of scope for v1.
