How To Enhance JavaScript File Upload Experience In Your Web App?

Kickstart your JavaScript file upload with Filestack.

Many web applications collect information from the selected files and transmit it to the page. While a basic upload form can do the trick, an API service is needed to expand on modern features. This includes drag and drop, remote storage, image editing, and multiple attachments. A ready-made solution can add layers of functionality to a JavaScript file upload. So once you secure the upload form to whitelist file types, it’s time to push some pixels on the front end.

What you should aim for is a responsive user interface that not only looks amazing, but also performs the actions expected by the user. A JavaScript file uploader ensures convenient, fast-moving uploads on every device, to handle a host of file sizes whenever a user pastes content into the upload container. Ideally, you should limit the number of user interactions by making it easier to navigate the form. 

What Is The Least Confusing UI For Invoking A JavaScript File Upload?

A professional UX design has visually-appealing graphics and clear instructions for users, where all available options are shown and the form data is converted via a POST request. While the visual presentation is important, it’s better to tread on familiar ground with a design that users already understand. 

By employing the best practices, let’s dive into what kind of UI would mesh well with a custom JavaScript file uploader.

You can start by improving the “choose a file” dialogue box: A good template should include the “drag file here” text and an up arrow or cloud icon to prompt the user. A preview option is equally valuable since it forecasts how the file data might appear inside a web app. 

Aside from picking an agreeable color scheme, you have to arrange the elements into a visual format that connects with your audience. It would be helpful to list supported file types next to the upload button for the user to reference. For groups of files, consider sorting their names into columns before confirming the full path. 

Can UX Guidelines Be Applied To Enhance The User Experience?

Yes, at its core, UX is the backbone of usability for web apps that users rely on to complete tasks. On SaaS products, a JavaScript file upload would enable users to attach documents, images, and videos, thereby improving the dashboard experience with additional functionality. 

In practice, UX is defined by the following design principles: 

  • The UI is where product interactions occur, whereas the user experience refers to the emotional outcome afterwards.
  • Understanding your audience by conducting user research to learn about their preferences and behavior is important.
  • Testing the interface should involve real users: You want the feedback of people from diverse backgrounds with different goals. 
  • Ensure your users aren’t distracted by information overload, which could deter them from revisiting your site.
  • Keep your web design simple and consistent when working with content placeholders.

The file input and button are points of contact for users to transfer their data in the browser. Specifically, they need to stand out from the background elements, which means adding a border around the dialogue box.

On the surface, your users won’t notice the difference between a simple image upload versus one that has to process complex information. And yet, a JavaScript file uploader must be able to perform scalable file imports in record time.

Are There Any Useful Tips For Customizing A JavaScript File Upload?

In this section, we’ll walk you through how visual components can revamp the user experience of a JavaScript file upload. While CSS properties deliver smoother graphics, an API would help address use cases that deviate from the norm. 

Consider building a drop-down to let the user choose what platform to import file data from. For multiple uploads, the web app can fetch a table that maps out the file previews, to show users how the texts and images fit together on a page. 

Likewise, there should be options to save or remove uploaded files for your users, and a JavaScript API can optimize them with minimal server load. If an upload is unsuccessful, the user must be notified of the potential cause via an error message. 

How Do You Merge Filestack’s File Picker With A JavaScript File Uploader?

The Web File Picker is an open-source JavaScript SDK that integrates with your web application. To launch the client, include the UMD module and grab your API key. Open the picker to start working on different use cases. They are grouped into the picker, store, upload, transformation, and accept options. 

Under PickerOptions are parameters that control your file instance. From here, it’s easy to customize what the user sees on the upload dialog box. There are many tried and true methods to enhance the user experience:

  1. Hide the modal UI once a file begins uploading with hideModalWhenUploading to avoid covering the screen
  2. Use imageDim to crop or scale down files while retaining the original width/height ratio
  3. Change how the file browser is structured with grid or list as the viewType 
  4. Specify the allowable file types (e.g. PDF, JPEG, or text/*) through the Accept parameter
  5. Use fromSources to unveil a list of sources that are compatible with your uploader
  6. Decide whether the Picker should upload immediately after the user selects a file 
  7. Toggle the resolution of uploaded videos to fit the screen size using videoResolution
  8. Switch to another display mode like overlay, dropPane, or inline to fix an overlapping container layout on mobile devices
