## Usage ## Usage
Use TypeScript for best in class instellisense. @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.
Under the hood we use socket.io and shortid for managed data exchange. ### Getting Started
### Serverside 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 ```typescript
import * as smartsocket from 'smartsocket'; import { Smartsocket } from '@push.rocks/smartsocket';
import * as q from q; // q is a promise library
// The "Smartsocket" listens on a port and can receive new "SocketConnection" requests. // Create a new instance of Smartsocket for the server.
let mySmartsocket = new smartsocket.Smartsocket({ const server = new Smartsocket({ alias: 'myServer' });
port: 3000, // the port smartsocket will listen on
// 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}!` };
}
}); });
// optional: // Start the Smartsocket server
// run this with anothoer existing server like express server.start().then(() => {
declare var someExpressServer; // read the express docs about how express actually works console.log('WebSocket server is running...');
mySmartsocket.setServer(someExpressServer);
// A "SocketRole" can be referenced by "SocketFunction"s.
// All "SocketRequest"s carry authentication data for a specific "SocketRole".
// "SocketFunction"s know which "SocketRole"s are allowed to execute them
let mySocketRole = new smartsocket.SocketRole({
name: 'someRoleName',
passwordHash: 'someHashedString',
});
// A "SocketFunction" executes a referenced function and passes in any data of the corresponding "SocketRequest".
// The referenced function must return a promise and resolve with data of type any.
// Any "SocketRequest" carries a unique identifier. If the referenced function's promise resolved any passed on argument will be returned to the requesting party
let testSocketFunction1 = new smartsocket.SocketFunction({
funcName: 'testSocketFunction1',
funcDef: (data) => {
console.log('testSocketFunction1 executed successfully!');
},
allowedRoles: [mySocketRole], // all roles that have access to a specific function
});
// A "Smartsocket" exposes a .clientCall() that gets
// 1. the name of the "SocketFunction" on the client side
// 2. the data to pass in
// 3. And a target "SocketConnection" (there can be multiple connections at once)
// any unique id association is done internally
mySmartsocket.clientCall('restart', data, someTargetConnection).then((responseData) => {});
```
#### Client side
```typescript
import * as smartsocket from 'smartsocket';
// A "SmartsocketClient" is different from a "Smartsocket" in that it doesn't expose any public address.
// Thus any new "SocketConnection"s must be innitiated from a "SmartsocketClient".
let testSmartsocketClient = new smartsocket.SmartsocketClient({
port: testConfig.port,
url: 'http://localhost',
password: 'testPassword',
alias: 'testClient1',
role: 'testRole1',
});
// You can .connect() and .disconnect() from a "Smartsocket"
testSmartsocketClient.connect().then(() => {
done();
});
// The client can also specify "SocketFunction"s. It can also specify "SocketRole"s in case a client connects to multiple servers at once
let testSocketFunction2 = new smartsocket.SocketFunction({
funcName: 'testSocketFunction2',
funcDef: (data) => {}, // the function to execute, has to return promise
allowedRoles: [],
});
// A "SmartsocketClient" can call functions on the serverside using .serverCall() analog to the "Smartsocket"'s .clientCall method.
mySmartsocketClient.serverCall('function', functionCallData).then((functionResponseData) => {
// the functionResponseData comes from the server... awesome, right?
}); });
``` ```
> **NOTE:** ### Creating a WebSocket Client
> you can easily chain dependent requests on either the server or client side with promises.
> `data` is always a js object that you can design for your specific needs.
> It supports buffers for large binary data network exchange.
## Contribution Create a client that connects to the WebSocket server and interacts with it:
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
import { SmartsocketClient } from '@push.rocks/smartsocket';
For further information read the linked docs at the top of this readme. // Create a SmartsocketClient instance and connect to the server
const client = new SmartsocketClient({
url: 'ws://localhost',
port: 3000,
alias: 'myClient'
});
## Legal client.connect().then(() => {
> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc) console.log('Connected to WebSocket server');
| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy) });
// 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.
For more detailed documentation, visit [the official @push.rocks/smartsocket GitLab repository](https://gitlab.com/pushrocks/smartsocket).
Remember, WebSocket communication with @push.rocks/smartsocket is not only about sending and receiving messages. It's about creating a fast, reliable, and secure communication channel for your real-time applications.
Happy coding!
