http.createServer

function createServer<Request extends typeof IncomingMessage = typeof IncomingMessage, Response extends typeof ServerResponse = typeof ServerResponse>(
requestListener?: RequestListener<Request, Response>
): Server<Request, Response>;

Returns a new instance of Server.

The requestListener is a function which is automatically added to the 'request' event.

import http from 'node:http';

// Create a local server to receive data from
const server = http.createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'application/json' });
  res.end(JSON.stringify({
    data: 'Hello World!',
  }));
});

server.listen(8000);
import http from 'node:http';

// Create a local server to receive data from
const server = http.createServer();

// Listen to the request event
server.on('request', (request, res) => {
  res.writeHead(200, { 'Content-Type': 'application/json' });
  res.end(JSON.stringify({
    data: 'Hello World!',
  }));
});

server.listen(8000);

  • readonly body: null | ReadableStream<Uint8Array<ArrayBufferLike>>
  • readonly bodyUsed: boolean
  • readonly cache: RequestCache

    Returns the cache mode associated with request, which is a string indicating how the request will interact with the browser's cache when fetching.

    MDN Reference

  • readonly credentials: RequestCredentials

    Returns the credentials mode associated with request, which is a string indicating whether credentials will be sent with the request always, never, or only when sent to a same-origin URL.

  • readonly destination: RequestDestination

    Returns the kind of resource requested by request, e.g., "document" or "script".

    MDN Reference

  • readonly headers: Headers

    Returns a Headers object consisting of the headers associated with request. Note that headers added in the network layer by the user agent will not be accounted for in this object, e.g., the "Host" header.

    MDN Reference

  • readonly integrity: string

    Returns request's subresource integrity metadata, which is a cryptographic hash of the resource being fetched. Its value consists of multiple hashes separated by whitespace. [SRI]

    MDN Reference

  • readonly keepalive: boolean

    Returns a boolean indicating whether or not request can outlive the global in which it was created.

    MDN Reference

    Returns the referrer of request. Its value can be a same-origin URL if explicitly set in init, the empty string to indicate no referrer, and "about:client" when defaulting to the global's default. This is used during fetching to determine the value of the Referer header of the request being made.

    MDN Reference

  • readonly referrerPolicy: ReferrerPolicy

    Returns the referrer policy associated with request. This is used during fetching to compute the value of the request's referrer.

    MDN Reference

  • readonly signal: AbortSignal

    Returns the signal associated with request, which is an AbortSignal object indicating whether or not request has been aborted, and its abort event handler.

    MDN Reference

  • readonly url: string
  • blob(): Promise<Blob>;
  • bytes(): Promise<Uint8Array<ArrayBufferLike>>;
  • json(): Promise<any>;
  • text(): Promise<string>;

  • Returns a ReadableStream of the body decoded as UTF-8 text.
