What Are the Basics of File Uploading?

Accepting and managing a user’s computer files refers to file uploading. These files can be in the form of videos, images, PDFs, and other documents. Many websites require different types of files that they get from users through a file uploader. The files that a user uploads on websites are known as user-generated content (UGC).

Some examples of UGC are homework assignments on Coursera, Portfolios or CVs on Indeed and product photos on eBay or OLX. When a user clicks on a file uploader, it gives him a dialog box that allows the user to submit, attach, or choose files. Let’s check out some Must-Haves for a reliable file uploader.

Drag and drop allows the users to save time by just dragging files from a particular location and drop into the file uploader.

Uploading Files From Different Sources

Users can upload their files from their devices. However, to save time and make the process more convenient, a JavaScript file uploader must allow file uploading from different sources.

A few examples are the integration of Social Media, Cloud storage, URL upload, Flicker, and Huddle. Not every application may need these options, but adding them can make a website more user-friendly.

An intuitive and handy user interface also helps us with faster file uploads. For example, a preview feature must allow the users to preview files before they upload them. Moreover, there must be an option to upload multiple files across all devices or browsers.

Our file uploader should allow chunking large files that will ensure faster file uploads regardless of the size.

File uploads help us to increase the productivity of our JavaScript web pages. For example, these file uploaders are important in content management systems. Apart from them, multiple messaging applications, insurance sites, healthcare portals, etc., also require a file uploader.
