HTTP Sink

A trivial HTTP Sinkhole. Always returns a 200 OK and JSON response body with request details.

Usage

CLI

Start a sinkhole on port 8080 using npx:

# Listen on the default localhost:8080
npx httpsink

Alternatively install the module globally, then start a sinkhole:

npm install -g httpsink

# Listen on port 3000 on a public interface
httpsink --port 3000 --host '0.0.0.0'

Docker CLI

Here's a sample command that exposes the sinkhole on port 8080.

docker run -p 8080:8080 --rm --entrypoint /bin/sh node:14-alpine -c 'npx httpsink --host "0.0.0.0" --port 8080'

Module

const sinkhole = require('httpsink')

async function main () {
  // Create a sinkhole that listens on port 8080
  const server = await sinkhole({
    port: 8080
  })

  // ...sometime later call server.close() when you're done
  server.close()
}

main()

Response Format

Each request receives the same response format:

{
  // IP the server determines to be the origin of your request
  "ip": "127.0.0.1",

  // Unique ID generated for this request
  "uuid": "pDo-u-eOpxiVH_15aSV05",

  // When the server started processing the request
  "recv": "2021-02-04T19:25:03.740Z",

  // When the server sent the response
  "resp": "2021-02-04T19:25:03.744Z",

  // Bytes read for a request that sends a body
  "bodyBytesSize": 0

  // Bytes read for the entire HTTP transmission
  "totalBytesSize": 124

  // Method and URL that was requested
  "method":"POST",
  "url":"/json-test"
}
