I am working on a web-based video downloader project and would like to hear from other developers about the best practices they use when building this type of application.
The basic workflow is fairly simple: a user submits a video URL, the backend processes the request, and the application returns the available media information or download option.
However, several areas can become challenging, including:
Validating user-submitted URLs
Handling API requests and temporary media URLs
Managing failed or expired download requests
Protecting backend endpoints from abuse
Handling large video files efficiently
Keeping the frontend responsive while processing requests
Implementing appropriate rate limiting and security controls
I am currently exploring these issues while developing a Kuaishou video downloader project. You can see the project here: Kuaivideosdownloader.com
For developers who have built similar web applications, what architecture or security practices have worked well for you? Are there particular approaches you recommend for handling asynchronous video processing and temporary download URLs?
I would appreciate any practical suggestions or lessons learned from your experience.
