node-python-test

Simple tool to test python and node functions, useful if you're trying to port a function from one language to the other.

Creates a server API for both python (flask) and node (express) + a simple html/js page that makes a call with the same POST parameters to both servers, then compares the output of each.

What it does

• Dynamically loads functions from a functions/ folder in each server app and exposes each file as a POST endpoint named after the file (e.g., functions/add.py or functions/add.js -> /add).
• Every endpoint accepts JSON POST input, passes that input to the function, and returns a uniform response: { "input": <posted json>, "output": <function return> }.
• compare/index.html is a tiny client you can open in a browser to call a Python URL and a Node URL for a given function and payload, show both outputs, and indicate whether they match.

Quick start — Python

0. Install whatever version of python you want
1. Go to /python folder
2. Create a virtualenv and activate it (optional).
3. Install:

   pip install -r requirements.txt
   

4. Start server:

   python server.py
   

5. POST JSON to http://localhost:3100/<function> (e.g. /add).

To add a function: add functions/<name>.py that exports a callable (e.g. def run(...) or same-name function). The server will register /name.

Quick start — Node.js

0. Install whatever version of node you want
1. Go to /node folder
2. Install Node and dependencies:

   npm install
   

3. Start server:

   npm start
   

4. POST JSON to http://localhost:3200/<function>.

To add a function: add functions/<name>.js that exports a function (export run or named export matching the filename). The server will register /name.

Using compare/index.html

1. Open compare/index.html in a browser (file:// is fine).
2. Enter:
   • Python base URL (e.g. http://localhost:3100)
   • Node base URL (e.g. http://localhost:3200)
   • Function name (e.g. /add)
   • JSON payload (e.g. {"first":1,"second":2})
3. Click "Compare". The page will POST the payload to both endpoints, display each raw response, and show whether outputs match.

Notes:

• Functions should accept the same input shape and produce comparable outputs for valid comparison.
• Comparison is a strict JSON equality check.
