Batch Transform Feature Implementation Plan

Implement Batch Transform Feature with File Upload

Description: Implement a new batch transform feature that allows users to upload and process text files through a dedicated endpoint.

Technical Requirements:

• Create new route at /batch-transform
• Implement POST request handling using Flask
• Set up multipart/form-data form encoding
• Process files synchronously (no background queue)
• Limit file size to 5MB
• Support .txt files only in initial MVP

Security Measures:

1. Implement server-side file type validation
2. Generate randomized filenames for uploaded files
3. Implement content-type verification independent of browser headers

Frontend Requirements:

• Create simple upload form interface
• Implement basic error handling and user feedback

Additional Notes:

• Feature builds on learnings from previous get-file vulnerability
• Initial implementation focuses on MVP functionality
• Synchronous processing may need review for scaling

Acceptance Criteria:

• Route accepts POST requests with file uploads
• File size validation works correctly
• Only .txt files are accepted
• Security measures are properly implemented
• Upload form functions as expected
• Error handling provides clear user feedback
