# @push.rocks/smartnetwork
network diagnostics

## Install

To install `@push.rocks/smartnetwork`, run the following command in your terminal:

```bash
npm install @push.rocks/smartnetwork --save
```

This command will download `@push.rocks/smartnetwork` and add it to your project's `package.json` file.

## Usage

In this section, we will dive deep into the capabilities of the `@push.rocks/smartnetwork` package, exploring its various features through TypeScript examples. The package is designed to simplify network diagnostics tasks, including speed tests, port availability checks, ping operations, and more.

### Basic Setup

First, import the package into your project:

```typescript
import { SmartNetwork } from '@push.rocks/smartnetwork';
```

Then, create an instance of `SmartNetwork`:

```typescript
const myNetwork = new SmartNetwork();
```

### Performing a Speed Test

You can measure the network speed using the `getSpeed` method. This feature leverages Cloudflare's speed test capabilities to assess your internet connection's download and upload speeds.

```typescript
const speedTest = async () => {
  const speedResult = await myNetwork.getSpeed();
  console.log(`Download speed: ${speedResult.downloadSpeed} Mbps`);
  console.log(`Upload speed: ${speedResult.uploadSpeed} Mbps`);
  console.log(`Latency: ${speedResult.averageTime} ms`);
};

speedTest();
```

### Checking Port Availability Locally

The `isLocalPortUnused` method allows you to check if a specific port on your local machine is available for use.

```typescript
const checkLocalPort = async (port: number) => {
  const isUnused = await myNetwork.isLocalPortUnused(port);
  if (isUnused) {
    console.log(`Port ${port} is available.`);
  } else {
    console.log(`Port ${port} is in use.`);
  }
};

checkLocalPort(8080);  // Example port number
```

### Checking Remote Port Availability

To verify if a certain port is available on a remote server, use `isRemotePortAvailable`. This can help determine if a service is up and reachable.

```typescript
const checkRemotePort = async (hostname: string, port: number) => {
  const isAvailable = await myNetwork.isRemotePortAvailable(hostname, port);
  if (isAvailable) {
    console.log(`Port ${port} on ${hostname} is available.`);
  } else {
    console.log(`Port ${port} on ${hostname} is not available.`);
  }
};

checkRemotePort('example.com', 443);  // Checking HTTPS port on example.com
```

### Using Ping

The `ping` method allows you to send ICMP packets to a host to measure round-trip time and determine if the host is reachable.

```typescript
const pingHost = async (hostname: string) => {
  const pingResult = await myNetwork.ping(hostname);
  if (pingResult.alive) {
    console.log(`${hostname} is reachable. RTT: ${pingResult.time} ms`);
  } else {
    console.log(`${hostname} is not reachable.`);
  }
};

pingHost('google.com');
```

### Getting Network Gateways

You can also retrieve information about your network gateways, including the default gateway used by your machine.

```typescript
const showGateways = async () => {
  const gateways = await myNetwork.getGateways();
  console.log(gateways);

  const defaultGateway = await myNetwork.getDefaultGateway();
  console.log(`Default Gateway: `, defaultGateway);
};

showGateways();
```

### Discovering Public IP Addresses

To find out your public IPv4 and IPv6 addresses, the following method can be used:

```typescript
const showPublicIps = async () => {
  const publicIps = await myNetwork.getPublicIps();
  console.log(`Public IPv4: ${publicIps.v4}`);
  console.log(`Public IPv6: ${publicIps.v6}`);
};

showPublicIps();
```

The `@push.rocks/smartnetwork` package provides an easy-to-use, comprehensive suite of tools for network diagnostics and monitoring, encapsulating complex network operations into simple asynchronous methods. By leveraging TypeScript, developers can benefit from type checking, ensuring that they can work with clear structures and expectations.

These examples offer a glimpse into the module's utility in real-world scenarios, demonstrating its versatility in handling common network tasks. Whether you're developing a network-sensitive application, diagnosing connectivity issues, or simply curious about your network performance, `@push.rocks/smartnetwork` equips you with the tools you need.
