How can I download image in React?

Question

I want to try to download an image by clicking on a button, but when I click on the button, it is not downloading the image, but it is directly opening the image. But I want to download the image, so how can I download the image in React?

Answer 1

I came across this SO question trying to figure out how to download a PNG image and found that Shubham Verma's answer didn't quite do it for me as the downloaded file couldn't be opened. I needed to use arraybuffer to convert the image.

Here's the code that worked.

function App() {
  const download = e => {
    console.log(e.target.href);
    fetch(e.target.href, {
      method: "GET",
      headers: {}
    })
      .then(response => {
        response.arrayBuffer().then(function(buffer) {
          const url = window.URL.createObjectURL(new Blob([buffer]));
          const link = document.createElement("a");
          link.href = url;
          link.setAttribute("download", "image.png"); //or any other extension
          document.body.appendChild(link);
          link.click();
        });
      })
      .catch(err => {
        console.log(err);
      });
  };
  return (
    <div className="App">
      <a
        href="https://upload.wikimedia.org/wikipedia/en/6/6b/Hello_Web_Series_%28Wordmark%29_Logo.png"
        download
        onClick={e => download(e)}
      >
        <i className="fa fa-download" />
        download
      </a>
    </div>
  );
}

P.S.: The download approach was taken from the following answer, but I used plain fetch instead of Axios. Download binary file with Axios
