Text Extractor Chrome Extension

This Chrome extension extracts text from web pages and sends it to a WebSocket server whenever the page is fully loaded or navigated.

Prerequisites

Node.js installed on your machine.

Setup

WebSocket Server

First, set up the WebSocket server using Node.js:

Create a new directory for the server and navigate into it:
```
mkdir websocket-server
cd websocket-server
```
Initialize a new Node.js project and install the ws package:
```
npm init -y
npm install ws
```

Create a file named server.js and add the following code:

const WebSocket = require("ws");
const port = 8765;
const wss = new WebSocket.Server({ port });

wss.on("connection", (ws) => {
  console.log("Client connected");

  ws.on("message", (message) => {
    console.log(`Received message: ${message}`);
  });

  ws.on("close", () => {
    console.log("Client disconnected");
  });
});

console.log(`WebSocket server is running on ws://localhost:${port}`);

Start the WebSocket server:
```
node server.js
```
