Creating HttpRouter adapters

HttpRouter relies on the Hono router adapter interface for URL pattern matching and request dispatching. It does not ship with a built-in router. Instead, you supply a Hono Router instance that satisfies the adapter interface.

Implementing your custom Router adapter

In order to create an adapter you need to implement the Router contract from Hono. The interface defines three members:

./samples/router-adapter-contract.ts

import type { Result } from "hono/router";

interface Router<T> {
    name: string;
    add(method: string, path: string, handler: T): void;
    match(method: string, path: string): Result<T>;
}
