371fb9daa7 feat: skip SRV lookup for IP addresses and localhost
Performing DNS SRV lookups for hosts that are already direct IP
addresses or special-case hostnames like 'localhost' is
unnecessary.

In addition, several related test suite improvements
have been included:

- A bug in the Bedrock mock packet creation was fixed where the magic
  GUID was being written to an incorrect buffer offset.
- The DNS mocking strategy in the Java tests has been refactored for
  better accuracy by mocking the `dns.promises.Resolver` class.
- An error test for the Bedrock pinger was corrected to properly
  handle a promise rejection instead of a synchronous throw.

23299a9a07 fix: add timeout to SRV record lookup
The `dns.promises.resolveSrv` function used for SRV record lookups
does not have a user-configurable timeout. This could cause the entire
`pingJava` operation to hang for an extended period if the target's
DNS server unresponsive.

To make the SRV lookup more robust and respect the user-provided
timeout, this commit switches to using the `dns.promises.Resolver`
class.

# mineping
This JavaScript library provides an implementation of the Minecraft server ping protocol. **It allows you to gather information about a Minecraft server**, such as the MOTD, current online players, server icon (Java Edition only), and more.
[![npm version](https://img.shields.io/npm/v/@minescope/mineping.svg)](https://www.npmjs.com/package/@minescope/mineping)
Mirror on my [<img src="https://git.zeldon.ru/assets/img/logo.svg" align="center" width="20" height="20"/> Git](https://git.zeldon.ru/zeldon/mineping)
A simple and efficient JavaScript library for pinging Minecraft servers. It supports both Java and Bedrock editions through a async/await-friendly API.
`@minescope/mineping` automatically resolves SRV records for Java servers and parses rich status data, including MOTD, player counts, version info, and server icons. Comes with full TypeScript support.
*Mirror on my [<img src="https://git.zeldon.ru/assets/img/logo.svg" align="center" width="20" height="20"/> Git](https://git.zeldon.ru/zeldon/mineping)*
## Features
- **Dual Protocol Support:** Ping both Java and Bedrock servers with a consistent API.
- **SRV Record Resolution:** Automatically resolves SRV records for Java Edition servers, so you don't have to worry about custom ports.
- **Rich Data:** Parses the full response from servers, including player samples, favicons, gamemodes, and more.
- **Lightweight:** Has only **one** runtime dependency — [debug](https://www.npmjs.com/package/debug) (used for tracing).

To install `mineping`, simply run the following command:
```
```bash
npm i @minescope/mineping
```
> To install _beta_ version (if available), run: `npm i @minescope/mineping@next`
## API & Usage Examples
The library exports two main functions: `pingJava` and `pingBedrock`. Both are asynchronous and return a `Promise`.
### 1. Basic Server Ping
Java:
```js
import { pingJava } from "@minescope/mineping";
const data = await pingJava("0.0.0.0");
console.log(data)
```
```js
{
version: { name: '1.21.5', protocol: 770 },
enforcesSecureChat: true,
description: '§1Welcome to §2My Minecraft Server!',
players: { max: 20, online: 0 }
}
```
Bedrock:
```js
import { pingBedrock } from "@minescope/mineping";
const data = await pingBedrock("0.0.0.0");
console.log(data)
```
```js
{
edition: 'MCPE',
name: 'Dedicated Server',
levelName: 'Bedrock level',
gamemode: 'Survival',
version: { protocol: 800, minecraft: '1.21.84' },
players: { online: 0, max: 10 },
port: { v4: 19132, v6: 19133 },
guid: 12143264093420916401n,
isNintendoLimited: false,
isEditorModeEnabled: false
}
```
## Loading and configuration the module
### ES Modules (ESM)
If you are using ES Modules, you can import the library like this:
```js
import { pingJava, pingBedrock } from "@minescope/mineping";
```
### CommonJS
`mineping` is an ESM-only module — you are not able to import it with `require()`.
@ -40,34 +85,86 @@ const pingBedrock = (...args) =>
import("@minescope/mineping").then((module) => module.pingBedrock(...args));
```
## Usage
## Debugging
Ping a Java server with default options:
`mineping` uses the [`debug`](https://www.npmjs.com/package/debug) library to provide detailed tracing information, which can be useful for diagnosing connection issues or understanding the library's internal workings.
```js
import { pingJava } from "@minescope/mineping";
To enable debug logs, set the `DEBUG` environment variable when running your script. The library uses two namespaces:
const data = await pingJava("mc.hypixel.net");
console.log(data);
- `mineping:java` for the Java Edition pinger.
- `mineping:bedrock` for the Bedrock Edition pinger.
### Examples
**Enable all `mineping` debug logs:**
You can use a wildcard (`*`) to enable all logs from this library.
```bash
DEBUG=mineping:* node your-script.js
```
Ping a Bedrock server with custom options:
