I have a VueX module named auth
.
Here is the module:
export const auth = {
namespaced: true,
state: {
user: null,
status: {
loggedIn: true
}
},
actions: {
},
mutations: {
},
getters: {
currentUser(state) {
return state.user;
},
loggedIn(state) {
return state.status.loggedIn;
}
}
}
I've left out the actions and mutations for the sake of brevity. As you can see I have getters clearly defined. I register the module in my store.ts file like so:
import Vue from 'vue';
import Vuex from 'vuex';
import { auth } from './store/auth.module.js';
Vue.use(Vuex);
export default new Vuex.Store({
state: {
},
mutations: {
},
actions: {
},
modules: {
auth
}
});
Now I wish to access the getters in a component so I tried mapGetters(['auth/loggedIn'])
& mapGetters('auth', ['loggedIn'])
in computed however I get errors for both. Here's what it looks like:
computed: {
...mapGetters(['auth/loggedIn'])
}
I even tried accessing the getter directly via this.$store.getters['auth/loggedIn']
however this did not work.
Any idea about what could be the issue?
EDIT: Here's the error after i run the tns preview
command:

Webpack build done!

The issue was the import statement import Vue from "vue"
in file store.ts
I changed it to import Vue from "nativescript-vue"
and now things seem to work.
I've created an issue here https://github.com/NativeScript/NativeScript/issues/8570 as the wrong import is added by following suggested getting started steps in the official website here: https://nativescript-vue.org/en/docs/getting-started/quick-start/
