Running as a child process from NodeJS

[denvolok]

httpx version:

1.2.4

Current Behavior:

I'm trying to run httpx from a NodeJS script(typescript):

const { spawn } = require("node:child_process");

const cmd = spawn("httpx", [
  "-l",
  "/tmp/subdomains.txt",
  "-ct",
  "-v",
  "-debug",
]);

cmd.stdout.on("data", (data: any) => {
  console.log(`stdout: ${data}`);
});

cmd.stderr.on("data", (data: any) => {
  console.error(`stderr: ${data}`);
});

cmd.on("close", (code: any) => {
  console.log(`child process exited with code ${code}`);
});

I'm getting the following output, then the execution just stuck(I suppose before making any requests):

    __    __  __       _  __
   / /_  / /_/ /_____ | |/ /
  / __ \/ __/ __/ __ \|   /
 / / / / /_/ /_/ /_/ /   |
/_/ /_/\__/\__/ .___/_/|_|
             /_/              v1.2.4

Expected Behavior:

I expect to see the same output as if running command from cli.

Steps To Reproduce:

1. npx ts-node index.ts

Anything else:

NodeJS version: 16.17.0
Tested with Node's exec - the same problem.
Tested with native js - the same problem.
Tested subfinder - works as expected.

Try closing the stdin from your code:

child.stdin.end()
