batch_with_mux

Overview ¶

Package main demonstrates dureq batch processing using the mux handler pattern — pattern-based routing, global middleware, per-handler middleware, and context utilities for metadata access.

Compared to the plain batch example, this version:

• Registers a single "image.*" pattern handler that dispatches by task type
• Adds global logging middleware via srv.Use()
• Adds per-handler timing middleware
• Uses context utilities (GetJobID, GetTaskType, GetAttempt, GetHeaders, etc.)

Scenario: Same image processing pipeline as the plain batch example.

1. onetime: download a shared background template image
2. per-item: overlay each user's text onto the template and produce a result URL
