Introduction

This is PHP 7 based microservice template that can greatly speed up building of microservices.

Technology Stack

• PHP 7.1
• MySQL 5.7 / PerconaDB 5.7
• Memcached
• Slim Framework v3

How to use it

This is effectively a starter template. You can make changes in the src and the routes folder and have your microservice up and running in a few minutes (depending on what you're trying to do, of course).

Understanding the Structure

The template uses a variety of composer packages. The list is available in composer.json. Many of these are optional - look in src/Model to see which ones may be used.

The src Folder

This starts with namespace definition. The example has a namespace called Book. Inside our namespace, we have:

1. Entities - These are Doctrine entities - we're using Doctrine as an ORM here - so you can create and manage your schema with these.
2. Models - These contain any business logic you need to apply incoming our outgoing data.
3. Helpers - Any generic classes to help you do stuff can go here - if you're not using any third party composer packages.

The routes folder

This contains your microservice routes. It comes with versioned folders and the file within is self explanatory. We don't have controllers on purpose - they make you think like a monolith. A routes file will likely force you into a microservice mindset.

Create a Project with this template

Run:

composer create-project --stability dev meezaan/microservice-template project-name
