Quick Start

1. Attach Vue Query to the root component of your Vue application

   import { defineComponent } from "vue";
   import { useQueryProvider } from "vue-query";
   
   export default defineComponent({
     name: "App",
     setup() {
       useQueryProvider();
     },
   });

2. Use query

   import { defineComponent } from "vue";
   import { useQuery } from "vue-query";
   
   export default defineComponent({
     name: "MyComponent",
     setup() {
       const query = useQuery("todos", getTodos);
   
       return {
         query,
       };
     },
   });

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({
     enabled: false,
   });
   
   const query = useQuery(queryKey, queryFunction, options);
