You need to just follow few step to get image upload example using vue js and axios.

Step 1: Create Vue App

first we need to create vue cli app using bellow command:

vue create myApp

Step 2: Install Axios

Here we need to install axios npm package that will allow to make http request.

npm install --save axios vue-axios

Step 3: Use Axios

We need to use Axios package in main.js file of vue js app.

src/main.js

import Vue from 'vue'
import App from './App.vue'
import axios from 'axios'
import VueAxios from 'vue-axios'
   
Vue.use(VueAxios, axios)
   
Vue.config.productionTip = false
  
new Vue({
  render: h => h(App),
}).$mount('#app')

Step 4: Update App.vue File

In this step, we need to update app.vue file, because i updated component so.

src/App.vue

<template>
  <div id="app">
    <Example></Example>
  </div>
</template>
  
<script>
import Example from './components/Example.vue'
   
export default {
  name: 'app',
  components: {
    Example
  }
}
</script>

Step 5: Create Example Component

Here, we will create Example.vue component with following code.

src/components/Example.vue

<template>
  <div class="container">
    <div class="large-12 medium-12 small-12 cell">
      <h1>Vue JS Axios - Image Upload using PHP API - ItSolutionStuff.com</h1>
      <label>File
        <input type="file" id="file" ref="file" v-on:change="onChangeFileUpload()"/>
      </label>
        <button v-on:click="submitForm()">Upload</button>
    </div>
  </div>
</template>
  
<script>
  export default {
    data(){
      return {
        file: ''
      }
    },
  
    methods: {
      submitForm(){
            let formData = new FormData();
            formData.append('file', this.file);
  
            this.axios.post('http://localhost:8000/api.php',
                formData,
                {
                headers: {
                    'Content-Type': 'multipart/form-data'
                }
              }
            ).then(function(data){
              console.log(data.data);
            })
            .catch(function(){
              console.log('FAILURE!!');
            });
      },
  
      onChangeFileUpload(){
        this.file = this.$refs.file.files[0];
      }
    }
  }
</script>

Step 6: Create PHP API

in this step, we will create simple php file with "upload" folder on root directory and then we will use as api this file. so, simply add following code and run with localhost:8000 local server.

api.php

<?php
  
    header('Access-Control-Allow-Origin: *');  
  
    if (move_uploaded_file($_FILES["file"]["tmp_name"], "upload/".$_FILES['file']['name'])) {
        echo "done";
        exit;
    }
  
    echo "failed";
  
?>

Now you can run vue app by using following command:

sudo npm run serve
