React Multiple Images upload Overview

We’re gonna create a React.js Multiple Images Upload with Preview application in that user can:

• see the preview of images that will be uploaded
• see the upload process (percentage) of each image with progress bars
• view all uploaded files
• download link to file when clicking on the file name

Here are screenshots of our React App:

• Before upload:

• Upload is done:

• List of Images Display with download Urls:

• Show status for each image upload:

Web API for Image Upload & Storage

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

Methods	Urls	Actions
POST	/upload	upload a File
GET	/files	get List of Files (name & url)
GET	/files/[filename]	download a File

You can find how to implement the Rest APIs Server at one of following posts:

• Node.js Express File Upload Rest API example
• Spring Boot Multipart File upload (to static folder) example

Project Structure

After building the React project is done, the folder structure will look like this:

Let me explain it briefly.

• file-upload.service provides methods to save File and get Files using Axios.
• images-upload.component contains upload form for multiple images, preview, progress bar, list of uploaded images display.

• App.js is the container that we embed all React components.

• http-common.js initializes Axios with HTTP base Url and headers.

• We configure port for our App in .env
