Why am I getting Vue is not defined as an error here:
export default {
state: {
projects: {
loading: true,
failed: false,
lookups: [],
selectedId: 0
}
},
mutations: {
loadingProjectLookups (state, payload) {
state.projects.loading = true;
state.projects.failed = false;
}
},
actions: {
loadProjectLookups (context) {
return new Promise((resolve) => {
// VUE NOT DEFINED HERE:
Vue.http.get('https://my-domain.com/api/projects').then((response) => {
context.commit('updateProjectLookups', response.data);
resolve();
},
response => {
context.commit('failedProjectLookups');
resolve();
});
});
}
}
}
This is my vue config:
'use strict';
import Vue from 'vue';
import Vuex from 'vuex';
var VueResource = require('vue-resource');
/* plugins */
Vue.use(Vuex);
Vue.use(VueResource);
/* stores */
import importPageStore from './apps/import/import-page-store';
/* risk notification import */
import ImportApp from './apps/import/import-app.vue';
if (document.querySelector("#import-app")) {
var store = new Vuex.Store(importPageStore);
new Vue({
el: '#import-app',
store,
render: h => h(ImportApp)
});
}
My understanding is that Vue is defined globally and I cannot see why it is not defined. If I add import Vue from 'vue'
to my store then I get a message that http is not defined. So I need to work out why Vue appears not to be available globally as I shouldn't have to do this.
I am using webpack to build my vue components. I have other pages rendered using this methodology and they work just fine. But this one does not? I am honestly stumped as to why as I cannot see any differences. The page renders and works. I can see that Vue is working. How can it be undefined?
In a component, you can use this.$http
, however, in your store you will need to import Vue
every time.
What you can do, is create a service
folder and import Vue there. Then just reference your service in the store file.
There's an example here https://github.com/vuejs/vuex/issues/85
Which suggests something like this:
/services/auth.js
import Vue from 'vue'
export default {
authenticate(request) {
return Vue.http.post('auth/authenticate', request)
.then((response) => Promise.resolve(response.data))
.catch((error) => Promise.reject(error));
},
// other methods
}
In your store file:
import { AUTHENTICATE, AUTHENTICATE_FAILURE } from '../mutation-types'
import authService from '../../services/auth'
export const authenticate = (store, request) => {
return authService.authenticate(request)
.then((response) => store.dispatch(AUTHENTICATE, response))
.catch((error) => store.dispatch(AUTHENTICATE_FAILURE, error));
}
// other actions
This is how VueResource extends Vue
prototype.
Object.defineProperties(Vue.prototype, {
// [...]
$http: {
get() {
return options(Vue.http, this, this.$options.http);
}
},
// [...]
});
}
