Ajax Requests

Quasar recommends Axios during project initialization: Use Axios for Ajax calls? (Y/n)

Then you should create a new boot file axios.js that looks like this: (Here you can also specify additional settings for your axios instance)

import axios from 'axios'

export default async ({ Vue }) => {
  Vue.prototype.$axios = axios
  // ^ ^ ^ this will allow you to use this.$axios
  //       so you won't necessarily have to import axios in each vue file
}

TIP

Be sure to check out Prefetch Feature if you are using Quasar CLI.

Usage in your single file components methods will be like:

methods: {
  loadData () {
    this.$axios.get('/api/backend')
      .then((response) => {
        this.data = response.data
      })
      .catch(() => {
        this.$q.notify({
          color: 'negative',
          position: 'top',
          message: 'Loading failed',
          icon: 'report_problem'
        })
      })
  },

Usage in Vuex Actions for globally adding headers to axios (such as during authentication):

import axios from 'axios'

export function register ({commit}, form) {
  return axios.post('api/auth/register', form)
    .then(response => {
      commit('login', {token: response.data.token, user: response.data.user})
      setAxiosHeaders(response.data.token)
    })
}

function setAxiosHeaders (token) {
  axios.defaults.headers.common['Authorization'] = 'Bearer ' + token
}
