Having trouble with Vue3
and Vuex4
, I keep encountering this error:
Uncaught TypeError: Cannot read properties of undefined (reading 'state')

Attempting to assign "hello" to the message variable for use across the application. Here's my main.js
:
import { createApp} from 'vue'
import App from './App.vue'
import router from './router'
import { createStore } from 'vuex';
const store = createStore({
state(){
return{
message: 'hello'
}
}
})
createApp(App).use(router, store).mount('#app')
In my App.vue file, I'm trying to access it using the composition api with the computed function.
import { ref, computed } from 'vue'
import { useStore } from 'vuex'
export default {
name: 'App',
setup(){
const store = useStore();
const message = computed(() => store.state.message);
console.log(message.value);
return{ }
}
}
