vue-plugin-axios

Usage

Add Vue plugin

import Vue from 'vue'
import VueAxios from 'vue-plugin-axios'
import axios from 'axios'
import store from '@/store'

Vue.use(VueAxios, {
  axios, 
  // example config for axios instance
  config: { // axios instance config
    baseURL: 'http://localhost:8000/', // api URL
    headers: { ... }, // default headers
    ...
  },
  interceptors: {
    // this function shows how to add Authorization header to requests
    beforeRequest (config, axiosInstance) {
      // your auth token
      const token = store.state.auth.token

      if (token) {
        config.headers.Authorization = `Bearer ${token}`
      }
      
      return config
    },
    // this function shows how to add errors from server to client app
    beforeResponseError (error) {
      const { response, message } = error

      if (response) { // backend error
        // shows response error
        alert(error.response.data.message)
      } else if (message) { // network error
        alert(message)
      }
      
      // return Promise.reject(error)
    }
  }
})

Now you can access from a component:

// no need to import
export default {
  data: () => ({
    users: null
  }),
  async mounted () {
    // automatic data return, no need to ".data"
    this.users = await this.$get('api/get-users/')
    const randomUsers = await this.$get('https://randomuser.me/api/')
  }
}

Installation

1. npm install vue-plugin-axios --save or yarn add vue-plugin-axios
2. add Vue.use like in code above

This is how you can use with Nuxt.js (client + server):

export default ({ store, app }, inject) => {
  // Vue.use(VueAxios, for some reason did not work
  VueAxios.install(Vue, {
    axios,
    nuxtInject: inject
  })
}

Full API

$get(endpoint[, config])

$delete(endpoint[, config])

$head(endpoint[, config])

$options(endpoint[, config])

$post(endpoint[, data[, config]])

$put(endpoint[, data[, config]])

$patch(endpoint[, data[, config]])

Axios instance:

$axios or $http

For full response you can use:

const { data, status, statusText, headers } = await this.$axios.post('/api/get-users')

Set custom header:

$axios.setHeader('X-Custom-Header', 'value')

or multiple:

$axios.setHeader({
  auth: token, // thiw will set 'Authorization' header, no need prefix 'Bearer '
  'X-Custom-Header': 'value',
  'Y-Custom-Header': 'value'
})

Set Authorization token header:

$axios.setToken(token[, type = 'Bearer'])

Delete header:

deleteHeader('X-Custom-Header')
deleteHeader(['X-Custom-Header', 'Y-Custom-Header'])
