In this article, we'll discuss different problems developers face while creating a drag and drop file uploader. We'll also show you how you can easily implement drag and drop JS file uploader with Filestack.
A file uploader consists of a front-end file upload button that enables users to upload files, such as images, documents, etc., to the website or web app. For example, whenever you upload an image or video on Facebook or Instagram, you use a file upload button.
When a user uploads an image, a file uploader should show an image preview for a better user experience. We can also enhance the user experience by enabling multiple file uploads and displaying progress bars for uploads. Once a file is uploaded, we need to send it to the backend and store it on the server.
A file uploader must also be able to handle large files efficiently. A best practice is to split a large file into chunks and send these chunks to the server one by one periodically. Doing this will prevent errors and improve speed.
A drag and drop file uploader provides a graphical user interface for uploading files to a website or web app. When you add this functionality, users can simply drag and drop files on your webpage or web applications. For example, users can drag images from their OS and drop them on your website. Dragging and dropping can also be done from one browser to another browser.
When a user drags an image file or document over the specified drag area in the file uploader, the border of the uploader changes to solid. When you release the file, the uploader will show a progress bar. For image files, the uploader also shows a preview.
Many companies now add a drag and drop file uploader to their websites and web apps because it looks better compared to traditional file uploaders. Additionally, drag and drop file uploaders are easier to use, and they improve user experience.
