AngularJS services in Vue.js - vue.js

Question

I'm new to Vue.js and looking for the equivalent of a service in AngularJS, specifically for storing data once and getting it throughout the app.
I'll be mainly storing the results of network requests and other promised data so I don't need to fetch again on very state.
I'm using Vue.JS 2.0 with Webpack.
Thanks!

I think what u are seeking for is vuex, which can share data from each component.
Here is a basic demo which from my code.
store/lottery.module.js
import lotteryType from './lottery.type'
const lotteryModule = {
state: {participantList: []},
getters: {},
mutations: {
[lotteryType.PARTICIPANT_CREATE] (state, payload) {
state.participantList = payload;
}
},
actions: {
[lotteryType.PARTICIPANT_CREATE] ({commit}, payload) {
commit(lotteryType.PARTICIPANT_CREATE, payload);
}
}
};
export default lotteryModule;
store/lottery.type.js
const PARTICIPANT_CREATE = 'PARTICIPANT_CREATE';
export default {PARTICIPANT_CREATE};
store/index.js
Vue.use(Vuex);
const store = new Vuex.Store();
store.registerModule('lottery', lotteryModule);
export default store;
component/lottery.vue
<template>
<div id="preparation-container">
Total Participants: {{participantList.length}}
</div>
</template>
<script>
import router from '../router';
import lotteryType from '../store/lottery.type';
export default {
data () {
return {
}
},
methods: {
}，
computed: {
participantList() {
return this.$store.state.lottery.participantList;
}
},
created() {
this.$store.dispatch(lotteryType.PARTICIPANT_CREATE, [{name:'Jack'}, {name:'Hugh'}]);
},
mounted() {
},
destroyed() {
}
}
</script>

You don't need Vue-specific services in Vue2 as it is based on a modern version of JavaScript that uses Modules instead.
So if you want to reuse some services in different locations in your code, you could define and export it as follows:
export default {
someFunction() {
// ...
},
someOtherFunction() {
// ...
}
};
And then import from your Vue code:
import service from 'filenameofyourresources';
export default {
name: 'something',
component: [],
data: () => ({}),
created() {
service.someFunction();
},
};
Note that this is ES6 code that needs to be transpiled to ES5 before you can actually use it todays browsers.
