Invoke a Python function from JavaScript

As I ask this question, I acknowledge that it may have been asked many times before. If I missed the answers due to my ignorance, I apologize.

I have a hosting plan that restricts me from installing Django, which provided a convenient way to set up a REST API with routing settings.

What I am seeking is the ability to call a Python function from JavaScript code using a get/post method (I am currently using AngularJs, but the process would be similar for an Ajax get/post).

Let's consider I have a JavaScript controller named 'Employee' and a view called 'CreateEmployee'.

From my JavaScript view, I can invoke my CreateEmployee() function on the JavaScript controller. My inquiry is how can I call a specific function, like def CreateEmployee(params...), in my .py file?

All my research has led me to making get/post requests to my .py file, but I haven't found resources explaining how to execute a particular function.

It is possible that I am struggling to comprehend the communication between Python and client/server. Having spent a significant amount of time coding on ASP.NET WebForms, the limitations imposed by the absence of frameworks like Django have left me at a standstill.

Thank you

Python may not be the main player here. The execution of your JavaScript code happens on the client side, where it can only make HTTP requests (sync or async). What matters is how the web server / technology / language handles these HTTP requests, which makes Python irrelevant in this context. So, in the perspective of client-side JavaScript, you're not directly "calling a Python function", but rather sending and handling an HTTP request.

If your current web host doesn't support running Django (or any WSGI-compliant script), your alternatives might be using plain CGI (although it's quite outdated) or switching to PHP. Alternatively, consider finding a hosting provider that embraces modern technologies instead of living in the past ;)

Answer №2

In order to interact with your server side Python code, it's essential to have a method for communication over HTTP. Check out this helpful resource on Flask RESTful APIs.

When communicating over HTTP, you won't be directly calling Python functions.
