function-from-url

Dynamically load JavaScript functions directly from a URL.

function-from-url is a tiny Node.js module that fetches a JavaScript function from a URL and returns it as a callable function. Perfect for dynamically loading code at runtime.

🚀 Installation

npm install function-from-url

⚡ Usage

import { FunctionFromUrl } from 'function-from-url';

async function main() {
  // URL containing the JavaScript function body
  const url = 'https://example.com/my-function.js';

  const myFunc = await FunctionFromUrl(url);

  // Call the fetched function
  myFunc(); 
}

main();

✅ Example

Suppose the content at https://example.com/hello.js is:

console.log('Hello from a remote function!');

Then:

import { FunctionFromUrl } from 'function-from-url';

const func = await FunctionFromUrl('https://example.com/hello.js');
func(); // Prints: Hello from a remote function!

💡 Notes

- The fetched code should contain a valid function body (no top-level export or import statements).

- The returned function is a plain JavaScript function created using new Function().
