# Dependencies { #dependencies }

**FastAPI** has a very powerful but intuitive **<dfn title="also known as components, resources, providers, services, injectables">Dependency Injection</dfn>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.
