Hono

Use Katman with Hono on any runtime — Node.js, Bun, Deno, Cloudflare Workers.

Hono is a fast web framework that runs everywhere. Katman's Hono adapter mounts your procedures as a Hono handler.

Setup

import {  } from "hono"
import {  } from "katman/hono"

const  = new ()

// Existing routes
.("/api/health", () => .({ : "ok" }))

// Katman RPC
.("/rpc/*", (appRouter, {
  : () => ({
    : getDB(),
    : .get("user"),
  }),
}))

export default

Context from Hono

The context function receives Hono's Context object. Access middleware data via c.get():

katmanHono(appRouter, {
  : () => ({
    : .get("user"),           // from Hono middleware
    : .get("requestId"),
    : .env,                     // Cloudflare Workers bindings
  }),
})

Cloudflare Workers

import {  } from "hono"
import {  } from "katman/hono"

const  = new ()
.("/rpc/*", (appRouter, {
  : () => ({ : .env.DB }),
}))

export default
