Using Bootstrap: Vue File Upload example with Axios & Bootstrap

Overview

We're gonna create a Vuetify File upload awarding in that user can:

• meet the upload process (percent)
• view all uploaded files
• link to the file when clicking on the file proper name

Here are APIs that nosotros will use Axios to make HTTP requests:

Methods	Urls	Deportment
Mail service	/upload	upload a File
GET	/files	get Listing of Files (name & url)
Get	/files/[filename]	download a File

You can find how to implement the Balance APIs Server at one of following posts:
– Node.js Express File Upload Remainder API instance
– Node.js Express File Upload to MongoDB instance
– Node.js Express File Upload to Google Deject Storage example
– Spring Boot Multipart File upload (to static binder) case

Technology

• Vue two.6
• Axios 0.nineteen.2
• Vuetify 2

Setup Vuetify File Upload Project

Open cmd at the folder you lot want to save Project binder, run control:
vue create vuetify-upload-files

You lot will see some options, cull default (babel, eslint).

Afterward the Vue projection is created successfully, we import Vuetify with command: vue add together vuetify.
The Panel will show:

Open up plugins/vuetify.js, y'all can come across:

          import Vue from 'vue'; import Vuetify from 'vuetify/lib'; Vue.use(Vuetify); export default new Vuetify({ });                  

Then in main.js file, Vuetify object will added automatically to Vue App:

          import Vue from 'vue' import App from './App.vue' import vuetify from './plugins/vuetify'; Vue.config.productionTip = false new Vue({   vuetify,   render: h => h(App) }).$mountain('#app')                  

And vue.config.js:

          module.exports = {   transpileDependencies: ["vuetify"] };                  

Project Construction

Allow's remove unnecessary folders and files, then create new ones like this:

Let me explicate it briefly.

– plugins/vuetify.js imports Vuetify library, initializes and exports Vuetify object for main.js.
Nosotros don't demand to practise annihilation with these two files because the command add Vuetify helped us.

– UploadFilesService provides methods to save File and get Files using Axios.
– UploadFiles component contains upload class, progress bar, display of list files.
– App.vue is the container that we embed all Vue components.

– http-common.js initializes Axios with HTTP base of operations Url and headers.
– We configure transpile Dependencies and port for our App in vue.config.js

Initialize Axios for Vue HTTP Customer

At present we add Axios library with command: npm install axios.

Under src binder, we create http-mutual.js file like this:

          import axios from "axios"; export default axios.create({   baseURL: "http://localhost:8080",   headers: {     "Content-type": "application/json"   } });                  

Remember to change the baseURL, it depends on Remainder APIs url that your Server configures.

Create Service for File Upload

This service will apply Axios to send HTTP requests.
At that place are ii functions:

• upload(file): POST form data with a callback for tracking upload progress
• getFiles(): Become list of Files' information

services/UploadFilesService.js

          import http from "../http-common"; class UploadFilesService {   upload(file, onUploadProgress) {     let formData = new FormData();     formData.append("file", file);     render http.post("/upload", formData, {       headers: {         "Content-Blazon": "multipart/course-data"       },       onUploadProgress     });   }   getFiles() {     render http.get("/files");   } } export default new UploadFilesService();                  

– First nosotros import Axios as http from http-common.js.

– FormData is a data structure that can be used to store key-value pairs. Nosotros apply it to build an object which corresponds to an HTML form with append() method.

– We pass onUploadProgress to exposes progress events. This progress issue are expensive (change detection for each result), so you should only use when you desire to monitor it.

– Nosotros call the post() & get() method of Axios to ship an HTTP Post & Get asking to the File Upload server.

Create Component for Upload Files

Allow'south create a File Upload UI with Vuetify Progress Bar, Button and Alert. Nosotros also have Card and List Item Group for displaying uploaded files.

First nosotros create a Vue component template and import UploadFilesService:

components/UploadFiles.vue

          <template> </template> <script> import UploadService from "../services/UploadFilesService"; export default {   name: "upload-files",   data() {     render {     };   },   methods: {      } }; </script>                  

Then we define the some variables inside data()

          export default {   name: "upload-files",   data() {     return {       currentFile: undefined,       progress: 0,       bulletin: "",       fileInfos: []     };   }, };                  

• fileInfos is an array of {name, url} objects. Nosotros're gonna brandish its data in a Vuetify five-list and v-listing-detail-grouping.
• progress is the per centum of file upload progress.

Side by side nosotros define selectFile() method which helps us to become the selected Files from v-file-input element in HTML template afterward.

          export default {   proper noun: "upload-files",   ...   methods: {     selectFile(file) {       this.progress = 0;       this.currentFile = file;     },   } };                  

We too define upload() method as following:

          export default {   name: "upload-files",   ...   methods: {     ...     upload() {       if (!this.currentFile) {         this.bulletin = "Please select a file!";         return;       }       this.bulletin = "";       UploadService.upload(this.currentFile, (event) => {         this.progress = Math.round((100 * event.loaded) / upshot.full);       })         .then((response) => {           this.message = response.data.bulletin;           return UploadService.getFiles();         })         .then((files) => {           this.fileInfos = files.data;         })         .catch(() => {           this.progress = 0;           this.message = "Could not upload the file!";           this.currentFile = undefined;         });     },   } };                  

We check if the currentFile is hither or not. Then we phone call UploadService.upload() method on the currentFile with a callback.

The progress will exist calculated basing on consequence.loaded and event.total.
If the transmission is washed, nosotros phone call UploadService.getFiles() to become the files' data and assign the result to fileInfos array.

We besides need to exercise this work in mounted() method:

          consign default {   proper name: "upload-files",   ...   mounted() {     UploadService.getFiles().then(response => {       this.fileInfos = response.information;     });   } };                  

Now we implement the HTML template of the Upload File UI using Vuetify. Add together the following content to <template>:

          <template>   <div>     <div v-if="currentFile">       <div>         <5-progress-linear           v-model="progress"           color="light-blueish"           height="25"           reactive         >           <strong>{{ progress }} %</strong>         </v-progress-linear>       </div>     </div>     <v-row no-gutters justify="center" marshal="center">       <v-col cols="eight">         <v-file-input           show-size           label="File input"           @change="selectFile"         ></v-file-input>       </v-col>       <v-col cols="4" class="pl-2">         <v-btn color="success" nighttime small @click="upload">           Upload           <v-icon right dark>mdi-deject-upload</v-icon>         </v-btn>       </v-col>     </5-row>     <v-alert 5-if="bulletin" border="left" color="blue-grey" dark>       {{ message }}     </five-alert>     <5-card 5-if="fileInfos.length > 0" class="mx-auto">       <v-listing>         <v-subheader>Listing of Files</5-subheader>         <v-list-item-group color="main">           <five-list-particular five-for="(file, index) in fileInfos" :primal="index">             <a :href="file.url">{{ file.name }}</a>           </five-list-item>         </5-listing-item-group>       </v-list>     </v-card>   </div> </template>                  

In the code above, we use Vuetify Progress linear: v-progress-linear. This component will be responsive to user input with v-model. We bind the progress model (per centum) to display within of the progress bar.

The v-btn button will telephone call upload() method, then notification is shown with v-alert.

Add together Upload File Component to App Component

Open App.vue and embed the UploadFiles Component with <upload-files> tag.

          <template>   <five-app>     <v-container fluid manner="width: 600px">       <div class="mb-five">         <h1>bezkoder.com</h1>         <h2>Vuetify File Upload</h2>       </div>       <upload-files></upload-files>     </v-container>   </v-app> </template> <script> import UploadFiles from "./components/UploadFiles"; export default {   name: "App",   components: {     UploadFiles,   }, }; </script>                  

Configure Port for Vuetify File Upload App

Because most of HTTP Server use CORS configuration that accepts resources sharing restricted to some sites or ports. And then you lot need to configure port for our App.

Alter vue.config.js file past adding devServer:

          module.exports = {   transpileDependencies: ["vuetify"],   devServer: {     port: 8081,   }, };                  

We've set our app running at port 8081. vue.config.js will be automatically loaded by @vue/cli-service.

Run the App

Starting time you demand to run one of post-obit Rest APIs Server:
– Node.js Express File Upload Rest API example
– Node.js Express File Upload to MongoDB case
– Node.js Express File Upload to Google Deject Storage example
– Jump Kick Multipart File upload (to static folder) example
– Spring Boot Multipart File upload (to database) example

And then run this Vue File Upload App with command: npm run serve.

Open Browser with url http://localhost:8081/ and check the result.
