# Quick Start

1. Install `vue-query`

   ```bash
   $ npm i @tanstack/vue-query
   ```

   or

   ```bash
   $ pnpm add @tanstack/vue-query
   ```

   or

   ```bash
   $ yarn add @tanstack/vue-query
   ```

   or

   ```bash
   $ bun add @tanstack/vue-query
   ```

   > If you are using Vue 2.6, make sure to also setup [@vue/composition-api](https://github.com/vuejs/composition-api)

2. Initialize **Vue Query** via **VueQueryPlugin**

   ```tsx
   import { createApp } from 'vue'
   import { VueQueryPlugin } from '@tanstack/vue-query'

   import App from './App.vue'

   createApp(App).use(VueQueryPlugin).mount('#app')
   ```

3. Use query

   ```tsx
   import { defineComponent } from 'vue'
   import { useQuery } from '@tanstack/vue-query'

   export default defineComponent({
     name: 'MyComponent',
     setup() {
       const query = useQuery({ queryKey: ['todos'], queryFn: getTodos })

       return {
         query,
       }
     },
   })
   ```

4. If you need to update options on your query dynamically, make sure to pass them as reactive variables

   ```tsx
   const id = ref(1)
   const enabled = ref(false)

   const query = useQuery({
     queryKey: ['todos', id],
     queryFn: () => getTodos(id),
     enabled,
   })
   ```
