# @push.rocks/smartsocket
easy and secure websocket communication

## Install

To install @push.rocks/smartsocket, you can use npm or yarn as follows:

```shell
npm install @push.rocks/smartsocket --save
```
or
```shell
yarn add @push.rocks/smartsocket
```

## Usage

@push.rocks/smartsocket offers a robust solution for easy and secure WebSocket communication, utilizing Typescript for clean and maintainable code. Below are comprehensive examples covering various scenarios and features provided by the module.

### Getting Started

First, ensure you've installed the module as shown in the "Install" section. Once installed, you can start using @push.rocks/smartsocket in your project.

### Setting Up a WebSocket Server

To create a WebSocket server that clients can connect to:

```typescript
import { Smartsocket } from '@push.rocks/smartsocket';

// Create a new instance of Smartsocket for the server.
const server = new Smartsocket({ alias: 'myServer' });

// Define a SocketFunction that clients can call
server.addSocketFunction({
  funcName: 'greet',
  funcDef: async (data) => {
    console.log(`Server received: ${data.message}`);
    return { reply: `Hello, ${data.name}!` };
  }
});

// Start the Smartsocket server
server.start().then(() => {
  console.log('WebSocket server is running...');
});
```

### Creating a WebSocket Client

Create a client that connects to the WebSocket server and interacts with it:

```typescript
import { SmartsocketClient } from '@push.rocks/smartsocket';

// Create a SmartsocketClient instance and connect to the server
const client = new SmartsocketClient({
  url: 'ws://localhost',
  port: 3000,
  alias: 'myClient'
});

client.connect().then(() => {
  console.log('Connected to WebSocket server');
});

// Define a function to call the server's 'greet' function
async function greetServer(name) {
  const response = await client.serverCall('greet', { name: name, message: 'Hello!' });
  console.log(`Server replied: ${response.reply}`);
}

// Use the function
greetServer('Alice');
```

### Handling Disconnections and Reconnections

@push.rocks/smartsocket provides mechanisms to handle client disconnections and attempt reconnections:

```typescript
client.on('disconnect', () => {
  console.log('Disconnected from server. Attempting to reconnect...');
  client.connect();
});
```

### Sending Binary Data

The library supports the transmission of binary data efficiently:

```typescript
import fs from 'fs';

// Function to send a binary file to the server
async function sendBinaryData(filePath) {
  const fileBuffer = fs.readFileSync(filePath);
  await client.serverCall('sendFile', { file: fileBuffer });
}

sendBinaryData('./path/to/your/file.png');
```

### Securing Your WebSocket Communication

@push.rocks/smartsocket leverages secure WebSocket (WSS) connections to ensure that data transferred between the client and server is encrypted. When setting up your Smartsocket server or client, use `wss://` in your URL to enable secure communication.

### Advanced Usage

#### Mesh Networking

@push.rocks/smartsocket allows for the creation of complex mesh network configurations, enabling servers to communicate with other servers, forming a robust network with multiple nodes.

#### Scaling with @push.rocks/smartsocket

To scale your WebSocket services, you can utilize load balancers and ensure your @push.rocks/smartsocket instances are stateless to allow for horizontal scaling.

### Conclusion

This guide has covered how to set up basic WebSocket communication with @push.rocks/smartsocket, handle disconnections/reconnections, secure your communication, send binary data, and briefly touched on advanced concepts like mesh networking and scaling.
