In this article we would like to show you how to upload files in React.

Below example shows simple Form with <input type="file" /> element that helps us to select file from computer and upload it using FormData class and Ajax request.

Runnable example:

// ONLINE-RUNNER:browser;

//Note: Uncomment import lines during working with JSX Compiler.
// import React from 'react';

const Form = () => {
  const handleSubmit = (e) => {
    e.preventDefault();
    const formData = new FormData(e.target);
    fetch("/example/upload", {
      method: "POST",
      body: formData,
    })
      .then((response) => {
        response.text().then((text) => console.log(text));
      })
      .catch((error) => {
        console.error("File upload error!");
      });
  };
  return (
    <form onSubmit={handleSubmit}>
      <label htmlFor="userfile">Upload file:</label>
      <input type="file" id="userfile" name="userfile"></input>
      <input type="submit" value="Submit!"></input>
    </form>
  );
};

const root = document.querySelector("#root");
ReactDOM.render(<Form />, root);
