The error thrown is Uncaught TypeError: 'this' is not defined in the Vuex

<script setup>
import { useLayout } from '@/layout/composables/layout';
import { ref, computed ,onMounted} from 'vue';
import AppConfig from '@/layout/AppConfig.vue';
import auth from '@/auth';

const { layoutConfig, contextPath } = useLayout();

const user = ref({});

const checked = ref(false);
const submitted = ref(false);

const logoUrl = computed(() => {
    return `${contextPath}layout/images/${layoutConfig.darkTheme.value ? 'logo-white' : 'logo-dark'}.svg`;
});

const Login = () => {
  submitted.value = true;

  if (user.value.email && user.value.password) {

  this.$store.dispatch("auth/login", user);
  }
};
onMounted(() => {
      auth.authForm('#firebaseui-auth-container')
    });
</script>

i am facing an issue with storing Vuex login. I get an error when calling this line: this.$store.dispatch("auth/login", user). How can I resolve this problem?

Answer №1

Essentially,

<script setup>
/* you are here */
</script>

acts as a condensed version of

<script>
import { defineComponent } from 'vue'
export default defineComponent({
  setup() {
    /* you are here */
  }
})
</script>

Within the setup() function, the use of this is not available.

So, how can I interact with the store?

<script setup>
import { useStore } from 'vuex'

const store = useStore();
          /*  👆 retrieves the store for your Vue app
           *     (equivalent to `this.$store` in Options API)
           */

//...

const Login = () => {
  submitted.value = true;
  if (user.value.email && user.value.password) {
    store.dispatch("auth/login", user);
 // 👆
  }
};
</script>
