+interoperability of the HTTP library's own middleware.

+It consists only of the web standards stack and is compatible with many
+Browsers.
+
+## Interface
+
+Middleware interfaces can be defined in TypeScript as follows:
+
+```ts
+interface Middleware {
+  (request: Request, next: Handler): Response | Promise<Response>;
+}
+
+interface Handler {
+  (request: Request): Response | Promise<Response>;
+}
+```
+
+## Features

+
+- Compatible with `Handler`.
+
+  `Handler` is a powerful interface for handling HTTP requests. The `Middleware`
+  is purely an extension and compatibility with `Handler`.
+
+- It can access to the `Request`.
+- It can access the next handler.
+- It can call the next handler.
+- It can choose not to call the next handler.
+- It can access the next handler's return value (`Response`).
