# Middleware

You can add middleware to **FastAPI** applications.

A "middleware" is a function that works with every **request** before it is processed by any specific *path operation*. And also with every **response** before returning it.

* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.

	tm "time"

	r "golang.org/x/time/rate"
)

func Example() {
	fmt.Println("Hello, world!")
	// Output: Hello, world!
}

func ExampleLimiter() {
	// Uses fmt, time and rate.
	l := r.NewLimiter(r.Every(tm.Second), 1)
	fmt.Println(l)

== Declaring the dependencies substituted by an included build

By default, Gradle will configure each included build in order to determine the dependencies it can provide. The algorithm for doing this is very simple: Gradle will inspect the `group` and `name` for the projects in the included build, and substitute project dependencies for any matching external dependency.

In `dependencySubstitution` terms, the default substitutions are:
```

            // Check if the value is a FB generated id (static 24 chars)
            if (obj instanceof NSString && (obj.getContent().length() == 24)) {
                return obj.getContent().toCharArray().every {
                    Character.isDigit(it) || Character.isUpperCase(it)
                }
            }
            return false
        }

        @Override
        String toString() {
