No something to import wich will do all that form me, something like createNitroApp(params)?

import { listen } from 'listhen'
import {
  createApp,
  createRouter,
  H3EventContext,
  splitCookiesString,
  isEvent,
  getResponseStatus,
  getResponseStatusText,
  setResponseHeader,
  setResponseStatus,
  send,
  toNodeListener,
  EventHandlerRequest,
  H3Error,
  H3Event
} from 'h3'
import { createHooks } from 'hookable'
import { Headers } from 'ofetch'
import {
  createCall,
  createFetch as createLocalFetch,
  FetchOptions
} from 'unenv/runtime/fetch/index'


  function errorHandler(error: H3Error<unknown>, event: H3Event<EventHandlerRequest>) {
    setResponseHeader(event, 'Content-Type', 'text/html; charset=UTF-8');
    setResponseStatus(event, 503, 'Server Unavailable');

    let body: string;
    let title: string;

    if (error) {
      title = `${getResponseStatus(event)} ${getResponseStatusText(event)}`;
      body = `<code><pre>${error.stack}</pre></code>`;
    } else {
      title = 'Reloading server...';
      body = '<progress></progress><script>document.querySelector("progress").indeterminate=true<\/script>';
    }

    return send(
      event,
      `<!DOCTYPE html>
        <html lang='en'>
        <head>
          <meta charset='utf-8'>
          <meta name='viewport' content='width=device-width, initial-scale=1'>
          ${error ? '' : '<meta http-equiv="refresh" content="2">'}
          <title>${title}</title>

        </head>
        <body>
          <main class='container'>
            <article>
              <header>
                <h2>${title}</h2>

        </body>
      </html>
      `
    );
  }

  function joinHeaders(value: number | string | string[]) {
    return Array.isArray(value) ? value.join(', ') : String(value);
  }

  function normalizeCookieHeader(header: number | string | string[] = '') {
    return splitCookiesString(joinHeaders(header));
  }

  function normalizeCookieHeaders(headers: Headers) {
    const outgoingHeaders = new Headers();
    for (const [name, header] of headers) {
      if (name === 'set-cookie') {

          outgoingHeaders.append('set-cookie', cookie);
        }
      } else {
        outgoingHeaders.set(name, joinHeaders(header));
      }
    }
    return outgoingHeaders;
  }

      return response;
    }
    return new Response(response.body, {
      status: response.status,
      statusText: response.statusText,
      headers: normalizeCookieHeaders(response.headers),

  }

  // const nitroApp = useNitroApp()

  //@ts-ignore

  const _localFetch = createLocalFetch(localCall, globalThis.fetch);
  const localFetch = (input: string | Request, init: FetchOptions) => _localFetch(input, init).then(

  const hooks = createHooks()

  h3App.use(router)

  const captureError = (error: unknown, context: H3EventContext = {}) => {

useNitroApp is not what I need because i don't run nitro dev so all magic like #imports not work.

Can't import things from nitropack if in tsconfig is set to compile to commonjs

@Makkalay can you please either in plain English or your native language if more comfortable with, explain what you need to achieve? if not using nitro server, you can use h3 directly, if using nitro, you need to use nitro dev / nitro build commands.

@pi0 I can't cancel request in discord i think

I'm trying to replace a server engine used by some framework with the nitro server engine, and everything is fine.
I start nitro and pass it to that framework. Everything is fine.
Eg: in nitro plugin i call new Framework(nitroApp);

Now I need/want to do the opposite, start that framework (not nuxt) and pass nitro to it.
To do that, I need to create a nitroApp (not h3, because I want to be as close to the first approach as possible).
Eg: in that framework i call new Framework(nitroApp); when it is initialized.

nitro dev server also watches for file change. like I mentioned above, if you really really want to have two dev servers, solution is proxy.

it is simply NOT possible.

Any way, how I did it works, so far it is enough to test the behavior of one and the other variant. Thank
