I am receiving a bindata from the Nodejs server and now from that I need to display an image.

How can I achieve this? Is there any method to convert bindata to JPEG

    If the binary data is represented as a base64 string:

    // Base64 string data
    const data =

    If you just have an image URL, you can simply do:

    const imageURL = 'https://upload.wikimedia.org/wikipedia/commons/thumb/a/a7/React-icon.svg/1280px-React-icon.svg.png'
