Check-Host

check-host is a Node.js package that provides an API interface for interacting with Check-Host.net. This package allows you to perform various types of checks (such as HTTP, Ping, TCP, DNS) and use available nodes for testing.

Installation

You can install the package using npm:

npm install check-host

Usage

Import Classes

const { CheckHost, CheckContent } = require('check-host');

Setting Up CheckHost

1. Create an instance of CheckHost:

   const CH = new CheckHost();

2. Load the list of nodes:

   CH.loadNodes().then(() => {
     /* Set the URL to check and choose the desired check type */
     CH.SetUrl('google.com:443');
   
     /* Start the check using TcpCheck with specified nodes */
     CH.SCAN(CheckContent.TcpCheck, (results) => {
       console.log('Done Scan results:');
       console.log(results);
     });
   });

Available Checks

1. HTTP Check

Example:

CH.SCAN(CheckContent.HttpCheck, (results) => {
  console.log('Done Scan results:');
  console.log(results);
});

2. Ping Check

Example:

CH.SCAN(CheckContent.PingCheck, (results) => {
  console.log('Done Scan results:');
  console.log(results);
});

3. TCP Check

Example:

CH.SCAN(CheckContent.TcpCheck, (results) => {
  console.log('Done Scan results:');
  console.log(results);
});

4. DNS Check

Example:

CH.SCAN(CheckContent.DnsCheck, (results) => {
  console.log('Done Scan results:');
  console.log(results);
});

Available Check Functions

• HttpCheck(url, nodes): HTTP check for the specified URL with the given nodes.
• PingCheck(host, nodes): Ping check for the specified host with the given nodes.
• TcpCheck(host, nodes): TCP check for the specified host with the given nodes.
• DnsCheck(host, nodes): DNS check for the specified host with the given nodes.

Setting the URL

Example:

CH.SetUrl('https://npmjs.com');

Check Results

The results will be displayed in a formatted manner based on the type of check performed.

Node List

You can load the list of available nodes using the loadNodes() method in CheckHost. This list is used to specify which nodes you want to use for the checks.

Example:

CH.loadNodes().then(() => {
  console.log('Nodes loaded:', CH.nodes);
});
