Description
I am working on an application using Angular (front-end) and Hibernate (back-end). My use case involves uploading multiple images, which I convert to base64 format and send as JSON with additional information for each image from the front-end.

The issue I’m encountering is that the HTTP request exceeds the maximum size limit due to the large base64-encoded images. I’m struggling to find an optimal solution for this problem.

What I’ve Tried

• Base64 Conversion: I have converted the images to base64 to include them in the JSON payload, which is causing the size issue.

• Single Transaction Requirement: I need to keep the images in a single request because multiple database transactions are performed on the back-end that require all the information to be received together.

Research and Analysis

• Chunked Uploads: I’ve considered splitting the images into smaller chunks, but I am unsure how to handle the reassembly and ensure all the information is processed correctly in a single transaction.
• Alternative File Upload Methods: I have read about multipart uploads and other methods, but I am concerned about maintaining the integrity of the database transactions and ensuring that all images and their associated data are processed together.

Request for Help
Has anyone encountered a similar issue or can suggest a solution for handling large file uploads in Angular and Hibernate without exceeding the HTTP request size limit? Any guidance or best practices would be greatly appreciated.

Thank you!
