I am in the process of integrating vuex into my project. I have familiarized myself with mutations and actions for updating state properties. My main inquiry is regarding the most secure and effective method to update state components by retrieving data from an API. For instance:
Store.js
export default {
state {
prop1:'',
prop2:''
}
actions {
//What is the best approach for calling an API here and updating the values of prop1 and prop2
}
}
Take a look at this snippet from my ongoing project. I've added comments to help clarify certain sections of the code:
import {
PAGES_FIND,
PAGES_FIND_ERROR,
PAGES_FIND_SUCCESS,
} from '../mutation-types';
import { PagesAPI } from '../../api';
const state = {
loading: false, // keeps track of loading status for display purposes
error: null, // stores and displays API errors
pages: [], // holds fetched pages
};
const mutations = {
[PAGES_FIND](state) {
state.loading = true;
},
[PAGES_FIND_SUCCESS](state, payload) {
state.loading = false;
state.error = null;
state.pages = payload;
},
[PAGES_FIND_ERROR](state, payload) {
state.loading = false;
state.error = payload;
},
};
const getters = {};
/**
* AJAX calls are handled here using 'axios'
*/
const actions = {
/**
* Retrieves list of pages with optional params
* @param {Function} [commit] - Commit function
* @param {Object} [params={}] - Fetch parameters (e.g. filter, limit)
* @returns {Promise}
*/
fetchPages({ commit }, params = {}) {
commit(PAGES_FIND); // show 'Loading...' message in UI
return PagesAPI.find(params)
.then(res => commit(PAGES_FIND_SUCCESS, res.data))
.catch(err => commit(PAGES_FIND_ERROR, err));
},
};
const namespaced = true;
export default {
state,
getters,
mutations,
actions,
namespaced,
};Implementation of PageAPI is shown below for clarity within the actions:
/* eslint-disable import/prefer-default-export */
import axios from 'axios';
import config from '../../config';
const ENDPOINT = `${config.service.baseUrl}/pages`;
/**
* Function to retrieve pages
* @param {Object} params
*/
export const find = params => (
axios.get(ENDPOINT, { params })
