Note that when we open a file or edit a file in subsequent sections we will by default refer to the project root directory react-file-download and later we may not mention this directory name. When project directory creation is finished with all of its components then first task is to change the default title of the page. Create DownloadFile. It is always good idea to call the super constructor even if we do not initialize any variable here.

You have two approaches in coding style for downloading the file and give users Save As option to save the file according to their choice of place. I have the below code snippets that create URL with anchor tag, we pass the file name as employees.

I have another line of code as shown blow, which will give users Save As option. Next we have render function to render the elements of React app. Elements are the building blocks of React apps.

As we said in Introduction section that we will give users two options for downloading file using link or using button. File objects Blobs are not JSON, and therefore using an incorrect content-type will cause the request to fail. Web browsers automatically set the content-type header when sending a file in a POST request.

When we need to upload multiple files using Fetch, we have to use a new type of object called FormData. There may be times when you need to send files and other data in a POST request. This can sometimes be referred to as multipart data.
