+### `userUpdated`
+
+You can register an `userUpdated` hook to force refetch inside components:
+
+
+```vue{}[components/navbar.vue]
+<template>
+  <div>
+    <p v-for="(userInvoice, index) in userInvoices" key="index">
+      {{ index }}
+    </p>
+  </div>
+</template>
+
+<script>
+export default {
+  data() {
+    return {
+      unregisterUserHook: null,
+      userInvoices: []
+    }
+  },
+  async fetch() {
+    // get user related data
+  },
+  mounted() {
+    this.unregisterUserHook = this.$strapi.hook('userUpdated', (user) => {
+      this.$fetch()
+    })
+  },
+  beforeDestroy() {
+    if (this.unregisterUserHook) {
+      this.unregisterUserHook()
+    }
+  },
