SLIMAPI

An example web application API using the Slim PHP micro framework.

This project is aimed at PHP students who want to learn about SLim PHP, which is a lightweight and robust micro framework, and the different ways of structuring your application that it offers.

We build an application that has:

• Full User CRUD.
• PHP-DI Container and Routes with production optimization.
• Light ORM.
• Paging and filtering of results.
• Lightweight and easy validation
• Midware and CORs authentication.
• JWT authentication.
• Error Handler and Logg.

Use this project only for studies and knowledge, we emphasize that IT HAS NOT BEEN TESTED IN PRODUCTION. Suggestions are welcome!
