File upload in React

Educative Answers Team

How you upload files in React is similar to how you upload files in plain HTML and JavaScript.

We use the <input type="file"> HTML element and handle upload events in React components.

Example

Here is an example of uploading and displaying an image file.
We make a FileUpload component and store the file object in its state. Using event.target, we get the uploaded image file, update the component state, and finally display the image and its details.

Similarly, you can also upload and handle any file by slightly tweaking the code below.

import React from "react";
require("./style.css");

import ReactDOM from "react-dom";
import App from "./app.js";

ReactDOM.render(
  <App />,
  document.getElementById("root")
);
