• Parallel + Dependent Queries
• Mutations + Reactive Query Refetching
• Multi-layer Cache + Automatic Garbage Collection
• Paginated + Cursor-based Queries

  • Basic

Installation

npm install vue-query

or

yarn add vue-query

Usage

1. Attach vue-query to your Vue application

   import { createApp } from "vue";
   import { QueryClient, VUE_QUERY_CLIENT } from "vue-query";
   
   import App from "./App.vue";
   
   const queryClient = new QueryClient();
   queryClient.mount();
   
   createApp(App).provide(VUE_QUERY_CLIENT, queryClient).mount("#app");

2. Use query

   import { useQuery } from "vue-query";
   
   const query = useQuery("todos", getTodos);

3. If you need to update options on your query dynamically, make sure to pass it as reactive property

   const id = ref(1);
   const queryKey = reactive(["todos", { id }]);
   const queryFunction = () => getTodos(id);
   const options = reactive({
     staleTime: 60 * 60,
     onSuccess: () => {},
   });
   
   const query = useQuery(queryKey, queryFunction, options);

DevTools

This package provides built-in DevTools in the form of a Vue component.

Use VueQueryDevTools component in the main component of your application.

Check Examples section.

<script lang="ts">
import { defineComponent } from "vue";
import { VueQueryDevTools } from "vue-query/devtools";

export default defineComponent({
  name: "App",
  components: { VueQueryDevTools },
});
</script>

<template>
  <VueQueryDevTools />
</template>
