Can we use hono stacks with Durable Objects? And how can we do it? @yusukebe

I'm following this example for hono with durable objects: https://github.com/honojs/examples/tree/main/durable-objects

@sor4chi is creating a nice one for DO.

i've created a simple local helper for myself. The rpc client is fully typed to be used with durable object.

Here's what i have.

// hono type from DO class
export type DistributedLeaseHonoController = typeof DistributedLease['prototype']['app'];

// helper
import { type DurableObjectNamespace } from '@cloudflare/workers-types';
import { type Hono } from 'hono';
import { hc } from 'hono/client';

import { getDurableObjectFromName } from '~~/helpers/getDurableObjectFromName';

export const createClientForDO = <THonoType extends Hono>(params: {
	dObj: DurableObjectNamespace;
	idString: string;
	origin: string;
}) => {
	const stub = getDurableObjectFromName(params.dObj, params.idString);

	const doFetch = async (url: URL, init?: RequestInit): Promise<Response> => {
		// eslint-disable-next-line @typescript-eslint/no-unsafe-argument, @typescript-eslint/no-explicit-any
		const response = await stub.fetch(url, init as any);

		// eslint-disable-next-line @typescript-eslint/no-explicit-any, @typescript-eslint/no-unsafe-return
		return response as any;
	};

	// eslint-disable-next-line @typescript-eslint/no-explicit-any
	const client = hc<THonoType>(params.origin, { fetch: doFetch as any });

	return client;
};

// usage with RPC and HC stacks
const leaseRouteClient = createClientForDO<DistributedLeaseHonoController>({
		dObj: c.env.JobDistributedLease,
		idString: 'default',
		origin: new URL(c.req.url).origin,
	});
	const result = await leaseRouteClient.acquire.$get({
		query: { entityUid: 'd843c5af-9e97-4fc5-9a06-a1062430283c' },
	});
	const data = await result.json();

thanks for the amazing library @yusukebe
