导出要在控制台运行的功能

Question

A few days ago i found a code with something similar to this. There is no big deal at it, but a little thing interested me. It can be runned at the GoogleChrome Console.

As soon i serve the application with: npm run local

I can just go to the Console and type SoundModule.playMusic();

"local": "node node_modules/rollup/bin/rollup src/client/main.js --o client/bundle.js --f es && node --max-old-space-size=8192 index"

const SoundModule = {};

SoundModule.playMusic = async function(name) { .... };

export default SoundModule;

I'm really interested in how to write JS functions in my projects and run them using the Console, (since i don't know how to make it, i had to post a code snippet/node command)

Here it is the project that bough my question into life https://github.com/johncintron/nodin

Your best bet for making a function accessible in the console would be to attach it to the window object:

window.myFunction = () => 'hello!'

window is the global scope for the browser, and its properties can be referenced directly in the console without having to include the namespace, so you could simply type myFunction() in the console and it should return "hello!" to you.
