Windows 7 How to connect JavaScript to Python in an Chrome Addon?

[Rishab7]

I want to connect my .js code with my .py in a Chrome Add-on.
I want some text from JS being analyzed by the Python ki I've implemented. Then the return value from Python should get passed back to my JS file. Is this possible to do?
It's ok when the Add-on is only runnable locally. I'm looking for the easiest, not the best solution. Thank y'all
Right now, I've tried my best with the Python Shell import in JS, but I can't seem to get this to work. When add the "import {PythonShell} from "/python-shell";" the code simply stops working, including all the other functions.

Yes, it is possible to connect your JavaScript code with your Python code in a Chrome Add-on. There are several ways to achieve this, and I'll outline a couple of options for you.

1. Using a Native Messaging API: The Native Messaging API allows you to communicate between your Chrome extension and a native application, such as a Python script. The extension can pass messages to the native application, and the application can return responses back to the extension. This method is more secure and reliable but requires additional setup.
2. Using Fetch API or AJAX: You can make an AJAX request or use the Fetch API to send data from your JavaScript code to a Python server and receive a response back. This approach requires setting up a server-side script that handles the request and returns the response. You can use a lightweight Flask server or any other server-side framework to handle the Python code. For the first option, you will need to set up a native application that acts as a bridge between your extension and your Python code. You can find more information about setting up a Native Messaging API in the Chrome documentation. For the second option, here's a basic example: In your JavaScript code:

   function sendDataToPython(data) { fetch('[B]Link Removed[/B]', { method: 'POST', body: JSON.stringify({ text: data }), headers: { 'Content-Type': 'application/json' } }) .then(response => response.json()) .then(result => { // handle the result returned from Python console.log(result); }) .catch(error => { console.error('Error:', error); }); } // Call the function and pass your text data sendDataToPython('Your text data');

   In your Python code (using Flask framework):

   from flask import Flask, request, jsonify app = Flask(__name__) @app.route('/analyze', methods=['POST']) def analyze_text(): data = request.get_json() text = data['text'] # Perform analysis on the text using your Python code result = 'Your result' return jsonify(result) if __name__ == '__main__': app.run()

   In the above example, the JavaScript code makes a POST request to the Flask server running on localhost. The server receives the request and extracts the text data from the request body. Then, the server performs the analysis using your Python code and returns the result as a JSON response. Remember to install Flask on your Python environment by running pip install flask if you haven't already. I hope this helps you get started with connecting your JavaScript code with your Python code in a Chrome Add-on!
