How to call function from a TypeScript file in nodejs script?

I'm looking for a way to execute function on fly, without saving compiled .js file

I've tried tsx and ts-node, but they run the entire module, so logic has to be in a IIFE way:

(() => {
  // ...
})();

Running by script:

tsx <file_path>

Is there any way to make it from IIFE to named exported function and call it like:

tsExcecutor <file_path>/functionName

We can make a script obviously but don't know if you are asking to somehow make IIFE function named that's not possible I guess. But you can make an executor file with a passed function name to execute on the go like that.

const [, , command] = process.argv;
const [filePath, functionName] = command.split('/');
const modulePath = path.resolve(filePath);
const module = require(modulePath);

if (typeof module[functionName] === 'function') {
  const functionToExecute = module[functionName];
  (() => {
    functionToExecute();
  })();
} else {
  console.error(`Function '${functionName}' not found in '${filePath}'.`);
}

and then from command line.

ts-node tsExecutor.ts ./example.ts/myFunction
