jconet-sockets v1.0.7

JCoNet Sockets

Description

JCoNet Sockets is a custom WebSocket package inspired by Pusher, providing an easy-to-use interface for real-time communication in web applications. It includes:

• Host: A standalone WebSocket server.
• Server-Side Client: For triggering events from your server-side code.
• Client-Side Client: For subscribing to channels and receiving events in the browser or Node.js applications.

Installation

Use your preferred package manager to install jconet-sockets:

# If you are using npm:
npm install jconet-sockets

# If you are using pnpm:
pnpm add jconet-sockets

# If you are using yarn:
yarn add jconet-sockets

# If you are using bun:
bun add jconet-sockets

Usage

Host

Set up the WebSocket host server. This can run independently on a server.

import { Host } from "jconet-sockets";

// Start the WebSocket host on port 8080
const host = new Host(8080);

Server-Side Client

Use the server-side client to trigger events from your backend application (e.g., in API routes or server processes).

import { ServerClient } from "jconet-sockets";

// Connect to the WebSocket host
const serverClient = new ServerClient("ws://localhost:8080");

// Trigger an event on a channel
serverClient.trigger("my-channel", "new-event", { message: "Hello World!" });

Client-Side Client

Use the client-side client in your frontend application to subscribe to channels and listen for events.

import { Client } from "jconet-sockets";

// Your JWT token for authentication
const token = "YOUR_JWT_TOKEN";

// Connect to the WebSocket host
const client = new Client("ws://localhost:8080", token);

// Subscribe to a channel
const channel = client.subscribe("my-channel");

// Listen for events on the channel
channel.on("new-event", (data) => {
  console.log("Received event data:", data);
});

// Optionally, trigger events from the client
channel.trigger("client-event", { clientData: "Hello from client!" });

Generating JWT Tokens

On your server, generate JWT tokens for authenticating clients. This ensures secure communication and channel authorization.

import { generateToken } from "jconet-sockets";

// Generate a token for a user with access to specific channels
const token = generateToken("user-id", ["my-channel", "another-channel"]);
