The Advantages of Multipart Upload in Forms

In the ever-evolving landscape of web development, creating efficient and user-friendly forms is crucial. One key technique that has gained popularity among developers is multipart upload in forms.

We use this multi-part file uploads in our VibeBP & other addon, surprisingly even WordPress’s famous media file uploader does not have an inbuilt multi-part file upload. The most famous protocol on multi-part file uploads is the Tus which is used by Vimeo, Youtube, media share etc. where large files are involved. Explaining how that protocol works is perhaps for a different article.

This method allows users to upload multiple files simultaneously and offers numerous advantages, making it a valuable addition to any web application. In this article, we will delve into the advantages of multipart upload in forms and explore real-world examples to illustrate its benefits.

1. Enhanced User Experience

Improved User Feedback

Multipart upload in forms enhances the overall user experience by providing immediate feedback and progress updates during file uploads. Users appreciate transparency, and this feature keeps them informed about the status of their uploads. For instance, consider a job application website that allows applicants to submit their resumes and cover letters. With multipart upload, applicants can see a progress bar indicating the status of their file uploads. This real-time feedback reassures users that their documents are being processed, reducing frustration and uncertainty.

Resumable Uploads

Another significant advantage is the ability to resume interrupted uploads. In the past, a poor internet connection or accidental browser closure during file upload could lead to lost data and user frustration. Multipart upload allows users to resume the upload process from where it left off, ensuring that their efforts are not wasted. For instance, imagine a cloud storage platform like Google Drive. If a user is uploading a large video file and the upload is interrupted, they can simply restart the upload process without having to re-upload the entire file. This not only saves time but also enhances the reliability of your application.

2. Efficient Handling of Large Files

Reduced Server Load

Multipart upload is particularly advantageous when dealing with large files. Uploading a massive file in a single request can strain server resources and slow down the application. However, by breaking the file into smaller chunks and uploading them individually, the server load is distributed evenly. For instance, a video-sharing platform like YouTube allows users to upload large video files. With multipart upload, YouTube can efficiently process these uploads without overloading their servers, ensuring a smooth user experience for both uploaders and viewers.

Error Handling and Recovery

Large file uploads are more prone to errors, such as timeouts or network issues. Multipart upload handles errors gracefully by allowing the application to retry uploading individual chunks that failed, rather than starting the entire upload from scratch. For example, an e-commerce website that enables customers to upload high-resolution images for product customization can benefit from multipart upload. If an image upload encounters an error due to a network glitch, the website can automatically retry uploading the failed chunk, ensuring that the image is eventually uploaded correctly. This robust error handling ensures that users’ valuable data is not lost due to intermittent issues.

In conclusion, multipart upload in forms offers significant advantages in terms of user experience and efficient handling of large files. By providing real-time feedback and enabling resumable uploads, it enhances the overall usability of web applications. Additionally, its ability to reduce server load and handle errors efficiently makes it indispensable when dealing with large files. Incorporating multipart upload into your forms can greatly improve your users’ interaction with your web application and lead to higher user satisfaction.
