"Building a custom progress bar from scratch requires boilerplate JavaScript using XMLHttpRequest and its upload.onprogress event."
"A frontend-only progress bar is useless without a server-side endpoint to receive the file, adding more complexity."
"The Filestack picker automatically includes a reliable, professionally designed progress bar, with no extra code required."
"The manual approach forces you to manage DOM updates and calculations yourself."
Building an image uploader requires more than a basic file input; users need feedback during uploads. A progress bar enhances user experience by providing real-time updates. Creating one from scratch involves utilizing XMLHttpRequest for monitoring upload progress, which demands managing event listeners and DOM elements. Additionally, a frontend-only progress bar lacks functionality without a server-side endpoint for receiving files. Alternatives like the Filestack picker offer professional-grade progress bars without needing extra code, ensuring a smoother integration.
