Axum Jetpack

This project should be considered experimental for now. It contains a collection of tools to improve the axum framework and security aspects.

Currently it contains the following features:

• Size limit middleware: A configurable middleware for Axum framework that enforces request size limits with intelligent buffering and streaming strategies.

  Features

  • Content-Type Based Limits - Set different limits for different content types
  • Wildcard Support - Use patterns like image/* or video/*
  • Buffering Strategy - Intelligent decision to buffer or stream
  • Human-Readable Sizes - Use strings like "10MB" or "100KB"
  • Early soft rejection - First weak rejection based on Content-Length header
  • Early hard rejection - Counts bytes and disallows request if limit is exceeded.
  • Streaming Support - Handle large files without buffering
  • Customizable Defaults - Configure default behavior
  • Multipart Support - Handle file upload limits
  • Production Ready - Proper error handling and responses

  Important notes:

  • This middleware is only effective when also other axum limits set correctly. Like: Timeouts, Max concurrent connections, CORS etc.
  • Notice that also default axum limits are enforced which can conflict with this middleware. Make sure to set them correctly.
