## Slow Server Simulation:
For simulating a slow server you can precede each endpoint (besides image endpoints) with the word "delay".
This will cause a 3 seconds delay for that route.
This can help test how your frontend behaves when performing an http request to a slow server.

### Examples:
- ```GET``` ```http://localhost:3030/api/products``` → Gets all products without any delay.
- ```GET``` ```http://localhost:3030/delay/api/products``` → Gets all products after a 3 seconds delay.
- ```GET``` ```http://localhost:3030/api/employees/7``` → Gets employee with id 7 without any delay.
- ```GET``` ```http://localhost:3030/delay/api/employees/7``` → Gets employee with id 7 after a 3 seconds delay.
- ```POST``` ```http://localhost:3030/api/suppliers``` → Adds a new supplier without any delay.
- ```POST``` ```http://localhost:3030/delay/api/suppliers``` → Adds a new supplier after a 3 seconds delay.
