Flask Multi Upload

Overview

The Flask Multi Upload Demo is an excellent showcase of how to create a multi-file uploader using Python and Flask. This app provides an intuitive interface for users, allowing them to easily upload multiple files while also entering related information. The integration of HTML5 features such as drag-and-drop functionality enhances the user experience, making it not only simple but also efficient.

This solution captures the essential aspects of multi-file uploads: users can interact with a clean form that collects their data and tracks their upload progress, all while maintaining compatibility with older clients. The straightforward implementation serves as a solid foundation for developers looking to incorporate similar functionality in their applications.

Features

• HTML5 Drag and Drop: Allows users to drag files from their computer directly onto the upload area, enhancing user convenience.
• Live Progress Bar: Offers real-time feedback on the upload process, so users know how much of the files have been successfully uploaded.
• Form Data Integration: Facilitates the submission of additional form data alongside files, allowing users to provide contextual information for their uploads.
• Backwards Compatibility: Ensures that the uploader works even for clients with scripts disabled, accommodating a wider range of users.
• Single Endpoint Handling: Streamlines the upload process using a single back-end endpoint for both form submissions and file uploads.
• Minimal Codebase: Keeping the JavaScript and Python code concise, the app is built with only 184 lines of JavaScript and 80 lines of Python, making it easy to understand and modify.
• Cross-Browser Compatibility: Designed to function across most modern browsers, including Internet Explorer 10 and above, ensuring broad accessibility.
• Public Domain License: Released freely for developers to use and adapt in their projects, encouraging sharing and collaboration within the community.
