vue-axios

vue-axios

A small wrapper for integrating axios to Vuejs

Why

I created this library because, in the past, I needed a simple solution to migrate from vue-resource to axios.

It only binds axios to the vue instance so you don't have to import everytime you use axios.

How to install:

ES6 Module:

npm install --save axios vue-axios

Import libraries in entry file:

// import Vue from 'vue'   // in Vue 2
import * as Vue from 'vue' // in Vue 3
import axios from 'axios'
import VueAxios from 'vue-axios'

Usage in Vue 2:

Vue.use(VueAxios, axios)

Usage in Vue 3:

const app = Vue.createApp(...)
app.use(VueAxios, axios)

Script:

Just add 3 scripts in order: vue, axios and vue-axios to your document.

Usage:

in Vue 2

This wrapper bind axios to Vue or this if you're using single file component.

You can use axios like this:

Vue.axios.get(api).then((response) => {
  console.log(response.data)
})

this.axios.get(api).then((response) => {
  console.log(response.data)
})

this.$http.get(api).then((response) => {
  console.log(response.data)
})

in Vue 3

This wrapper bind axios to app instance or this if you're using single file component.

in option API, you can use axios like this:

// App.vue
export default {
  name: 'App',
  methods: {
    getList() {
      this.axios.get(api).then((response) => {
        console.log(response.data)
      })
      // or
      this.$http.get(api).then((response) => {
        console.log(response.data)
      })
    }
  }
}

however, in composition API setup we can't use this, you should use provide API to share the globally instance properties first, then use inject API to inject axios to setup:

// main.ts
import { createApp } from 'vue'
import App from './App.vue'
import store from './store'
import axios from 'axios'
import VueAxios from 'vue-axios'

const app = createApp(App).use(store)
app.use(VueAxios, axios)
app.provide('axios', app.config.globalProperties.axios)  // provide 'axios'
app.mount('#app')

// App.vue
import { inject } from 'vue'

export default {
  name: 'Comp',
  setup() {
    const axios: any = inject('axios')  // inject axios

    const getList = (): void => {
      axios
        .get(api)
        .then((response: { data: any }) => {
          console.log(response.data)
        });
    };

    return { getList }
  }
}

Multiple axios instances support

The library allows to have different version of axios at the same time as well as change the default registration names (e.g. axios and $http). To use this feature you need to provide options like an object where:

• <key> is registration name
• <value> is instance of axios

For Vue it looks like this:

// Vue 2 / Vue 3 + Composition API
import App from './App.vue'
import VueAxios from 'vue-axios'
import axios from 'axios'
import axios2 from 'axios'
Vue.use(VueAxios, { $myHttp: axios, axios2: axios2 }) // or app.use() for Vue 3 Optiona API

// usage
export default {
  methods: {
    getList(){
      this.$myHttp.get(api).then((response) => {
        console.log(response.data)
      })
      this.axios2.get(api).then((response) => {
        console.log(response.data)
      })
    }
  }
}

It works similarly in Options API of Vue 3 but if you want to use Composition API you should adjust your code a bit to extract proper keys, e.g.:

// Vue 2 + Setup function
import { createApp } from 'vue'
import App from './App.vue'
import store from './store'
import axios from 'axios'
import VueAxios from 'vue-axios'

const app = createApp(App).use(store)
app.use(VueAxios, { $myHttp: axios, axios2: axios2 })
app.provide('$myHttp', app.config.globalProperties.$myHttp)  // provide '$myHttp'
app.provide('axios2', app.config.globalProperties.axios2)  // provide 'axios2'
app.mount('#app')

// App.vue
import { inject } from 'vue'

export default {
  name: 'Comp',
  setup() {
    const $myHttp: any = inject('$myHttp')  // inject $myHttp

    const getListWithMyHttp = (): void => {
      $myHttp
        .get(api)
        .then((response: { data: any }) => {
          console.log(response.data)
        });
    };

    const axios2: any = inject('axios2')  // inject axios2
    const getListWithAxios2 = (): void => {
      axios2
        .get(api)
        .then((response: { data: any }) => {
          console.log(response.data)
        });
    };


    return { getListWithMyHttp, getListWithAxios2 }
  }
}
