Introduction

Summary

An overview of Dotkernel Queue, a Mezzio-based microservice for processing asynchronous tasks via message queues.

Details

Dotkernel Queue is a standalone application (skeleton) for handling asynchronous task processing as its own microservice, separate from your API or Admin application.

Dotkernel Queue:

• Is built on the Mezzio microframework, sharing the same architecture and standards support as other Dotkernel tools and applications.
• Uses Laminas Messenger to dispatch and handle messages, so work can be processed outside the request/response cycle.
• Lets you offload slow or non-critical work — such as sending emails, generating exports, or processing uploads — from your API or Admin application.
• Has a PSR-Compliant Middleware Stack to promote a lean, modular architecture and create a common ground between components from various sources.
• Implements PSR-7 (HTTP message interfaces) and PSR-15 (HTTP Server Request Handlers) as defined by the PHP Framework Interop Group.
