Small, typed, promise-first ping checks for Node.js. @push.rocks/smartping wraps the proven ping package behind a tiny TypeScript API, so service health checks, diagnostics, readiness probes, and connectivity tests stay easy to read.

It uses the system ping command through the underlying dependency, so it is designed for Node.js environments with a working platform ping utility available.

What You Get

Smartping: a lightweight class for probing hosts.
ping(host, timeout?): returns the full ping response from the underlying ping.promise.probe(...) call.
pingAlive(host, timeout?): returns a boolean and converts ping failures into false.
TypeScript types, ESM exports, and direct async/await ergonomics.

Quick Start

import { Smartping } from '@push.rocks/smartping';

const smartping = new Smartping();

const response = await smartping.ping('127.0.0.1', 1);

console.log(response.alive); // true when the host responded
console.log(response.time);  // response time reported by the platform ping utility

API

`new Smartping()`

Creates a ping helper instance. The class is intentionally stateless, so you can create one per module, per service, or per check without setup.

import { Smartping } from '@push.rocks/smartping';

const smartping = new Smartping();

`smartping.ping(host, timeout?)`

Runs a ping probe and returns the full response object from ping.promise.probe(...).

const result = await smartping.ping('example.com', 2);

if (result.alive) {
  console.log(`${result.host} responded in ${result.time}`);
} else {
  console.log(`${result.host} did not respond`);
}

The timeout argument is passed to the underlying ping package as timeout, where it is documented as seconds. If omitted, @push.rocks/smartping uses its default value of 500.

`smartping.pingAlive(host, timeout?)`

Runs a ping probe and returns only the alive state.

const databaseHostIsReachable = await smartping.pingAlive('10.0.0.5', 1);

if (!databaseHostIsReachable) {
  throw new Error('Database host is not reachable');
}

pingAlive(...) is useful for health checks because it catches probe errors and returns false instead of throwing.

Usage Patterns

Service Health Check

import { Smartping } from '@push.rocks/smartping';

const smartping = new Smartping();

export const checkNetworkDependency = async () => {
  return smartping.pingAlive('api.internal.example', 1);
};

Diagnostics With Full Response Data

import { Smartping } from '@push.rocks/smartping';

const smartping = new Smartping();

const hosts = ['127.0.0.1', 'example.com', '10.0.0.5'];

for (const host of hosts) {
  const result = await smartping.ping(host, 1);
  console.log({
    host,
    alive: result.alive,
    output: result.output,
    time: result.time,
  });
}

Graceful Failure Handling

import { Smartping } from '@push.rocks/smartping';

const smartping = new Smartping();

try {
  const result = await smartping.ping('example.com', 1);
  console.log(result);
} catch (error) {
  console.error('Ping probe failed before producing a response:', error);
}

Use ping(...) when you need response details and want to decide how to handle errors yourself. Use pingAlive(...) when a simple true or false is the desired contract.

Runtime Notes

This package targets Node.js and ESM-based TypeScript projects.
The underlying ping package delegates to the operating system ping command.
Hosts can be DNS names or IP addresses accepted by the platform ping utility.
Timeout behavior is inherited from ping, including platform-specific details around system ping arguments.
