/**
* This file contains a helper class for integrating Convex with Hono.
*
* See the [guide on Stack](https://stack.convex.dev/hono-with-convex)
* for tips on using Hono for HTTP endpoints.
*
* To use this helper, create a new Hono app in convex/http.ts like so:
* ```ts
* import { Hono } from "hono";
* import { HonoWithConvex, HttpRouterWithHono } from "convex-helpers/server/hono";
* import { ActionCtx } from "./_generated/server";
*
* const app: HonoWithConvex<ActionCtx> = new Hono();
*
* app.get("/", async (c) => {
* return c.json("Hello world!");
* });
*
* export default new HttpRouterWithHono(app);
* ```

* Hono uses the `FetchEvent` type internally, which has to do with service workers

/**
* An implementation of the Convex `HttpRouter` that integrates with Hono by
* overridding `getRoutes` and `lookup`.
*
* This defers all routing and request handling to the provided Hono app, and
* passes along the Convex `HttpEndpointCtx` to the Hono handlers as part of
* `env`.
*
* It will attempt to log each request with the most specific Hono route it can
* find. For example,
*
* ```
* app.on("GET", "*", ...)
* app.on("GET", "/profile/:userId", ...)
*
* const http = new HttpRouterWithHono(app);
* http.lookup("/profile/abc", "GET") // [handler, "GET", "/profile/:userId"]
* ```
*
* An example `convex/http.ts` file would look like this:
* ```
* const app: HonoWithConvex = new Hono();
*
* // add Hono routes on `app`
*
* export default new HttpRouterWithHono(app);
* ```
