## Recap { #recap }

Apart from all the fancy words used here, the **Dependency Injection** system is quite simple.

Just functions that look the same as the *path operation functions*.

            } else {
                this.host = remaining.substring(0, slashIndex);
                this.path = remaining.substring(slashIndex);
            }

            // canonical form: remove . and .. but nothing fancy
            this.canonical = urlStr.replace("..", "").replace(".", "");
        }

You could use any other SQL or NoSQL database library you want (in some cases called <abbr title="Object Relational Mapper, a fancy term for a library where some classes represent SQL tables and instances represent rows in those tables">"ORMs"</abbr>), FastAPI doesn't force you to use anything. 😎
