```
This command will download `@push.rocks/smartnetwork` and add it to your project's `package.json` file.
## Usage ## 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 ```typescript
import { SmartNetwork } from '@push.rocks/smartnetwork'; import * as smartnetwork from 'smartnetwork';
``` const testSmartNetwork = new smartnetwork.SmartNetwork();
const run = async () => {
// measure average speed over a period of 5 seconds
// the structure of speedResult is self explanatory using TypeScript (or the linked TypeDoc above)
const speedResult: smartnetwork.SpeedResult = testSmartNetwork.getSpeed(5000);
Then, create an instance of `SmartNetwork`: // you can check for local ports before trying to bind to it from your nodejs program
const isLocalPortUnused: boolean = await testSmartNetwork.isLocalPortUnused(1234);
```typescript // you can run basic port checks on remote domains.
const myNetwork = new SmartNetwork(); const isRemotePortAvailable: boolean = await testSmartNetwork.isRemotePortAvailable(
``` 'google.com:80'
);
### Performing a Speed Test // just another way to call for the same thing as above
const isRemotePortAvailable: boolean = await testSmartNetwork.isRemotePortAvailable(
You can measure the network speed using the `getSpeed` method. It supports optional parameters: 'google.com',
- `parallelStreams`: number of concurrent streams (default: 1) 80
- `duration`: test duration in seconds (default: fixed segments) );
```typescript
const speedTest = async () => {
// Default fixed-segment test
let r = await myNetwork.getSpeed();
console.log(`Download: ${r.downloadSpeed} Mbps, Upload: ${r.uploadSpeed} Mbps`);
// Parallel + duration-based test
r = await myNetwork.getSpeed({ parallelStreams: 3, duration: 5 });
console.log(`Download: ${r.downloadSpeed} Mbps, Upload: ${r.uploadSpeed} Mbps`);
}; };
speedTest();
``` ```
### Checking Port Availability Locally ## Contribution
The `isLocalPortUnused` method allows you to check if a specific port on your local machine is available for use. We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
```typescript For further information read the linked docs at the top of this readme.
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 > MIT licensed | **©** [Lossless GmbH](https://lossless.gmbh)
``` | By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
### Checking Remote Port Availability [![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
To verify if a port is available on a remote server, use `isRemotePortAvailable`. You can specify target as `"host:port"` or host plus a numeric port.
```typescript
// Using "host:port"
await myNetwork.isRemotePortAvailable('example.com:443');
// Using host + port
await myNetwork.isRemotePortAvailable('example.com', 443);
// UDP is not supported:
try {
await myNetwork.isRemotePortAvailable('example.com', { port: 53, protocol: 'udp' });
} catch (e) {
console.error((e as any).code); // ENOTSUP
}
```
### Using Ping
The `ping` method sends ICMP echo requests and optionally repeats them to collect statistics.
```typescript
// Single ping
const p1 = await myNetwork.ping('google.com');
console.log(`Alive: ${p1.alive}, RTT: ${p1.time} ms`);
// Multiple pings with statistics
const stats = await myNetwork.ping('google.com', { count: 5 });
console.log(
`min=${stats.min} ms, max=${stats.max} ms, avg=${stats.avg.toFixed(2)} ms, loss=${stats.packetLoss}%`,
);
```
### Getting Network Gateways
You can also retrieve network interfaces (gateways) and determine the default gateway. Caching with TTL is supported via constructor options.
```typescript
// Create with cache TTL of 60 seconds
const netCached = new SmartNetwork({ cacheTtl: 60000 });
// List all interfaces
const gateways = await netCached.getGateways();
console.log(gateways);
// Get default gateway
const defaultGw = await netCached.getDefaultGateway();
console.log(defaultGw);
```
### Discovering Public IP Addresses
To find out your public IPv4 and IPv6 addresses (with caching):
```typescript
const publicIps = await netCached.getPublicIps();
console.log(`Public IPv4: ${publicIps.v4}`);
console.log(`Public IPv6: ${publicIps.v6}`);
```
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.
### Plugin Architecture
You can extend `SmartNetwork` with custom plugins by registering them at runtime:
```typescript
import { SmartNetwork } from '@push.rocks/smartnetwork';
// Define your plugin class or constructor
class MyCustomPlugin {
// plugin implementation goes here
}
// Register and unregister your plugin by name
SmartNetwork.registerPlugin('myPlugin', MyCustomPlugin);
// Later, remove it if no longer needed
SmartNetwork.unregisterPlugin('myPlugin');
```
Plugins enable you to dynamically augment the core functionality without altering the library's source.
