Importing Remote JavaScript Functions in Your Project

Ah, importing a function from a remote JavaScript file, huh? Now that's what I call living in the future. Not to worry, my friend, I've got you covered.

A Step-by-Step Guide on How to Fish a Function from the Internet Sea

Look, sometimes you find that gem of a function sailing on the internet, and you want to reel it into your code, right? No biggie. Here's how you do it like a pro.

Ingredients Required

  • A JavaScript file hosted remotely
  • Some knowledge of Webpack
  • Your local development setup

Instructions Fresh From the Oven

  1. Fetch The File: First thing you want to do is fetch the remote JavaScript file using a method like fetch or axios. You'll get a beautiful blob of text as a result.
fetch('https://remote-site.com/your-file.js')
  .then(response => response.text())
  .then(text => {
    // Do something with 'text'
  });
Enter fullscreen mode Exit fullscreen mode
  1. Eval Is Your New Best Friend: I know, I know, using eval feels like walking on a tightrope above a pit of snakes. But sometimes, you gotta do what you gotta do. Just make sure the remote JS is from a trusted source, capiche?
eval(text);
Enter fullscreen mode Exit fullscreen mode
  1. Invoke The Function: Once the eval has run, the function should be available globally, letting you call it like it's your neighbor asking for some sugar.
yourImportedFunction();
Enter fullscreen mode Exit fullscreen mode

Tips & Warnings

  • Be careful with eval, as it executes the code it's passed. Make sure your source is reliable.
  • If the remote JavaScript file is CORS restricted, you'll have to figure out a way to circumvent that, probably by using a server-side proxy.

Now You Know, So What's Next?

Alright, you got your function, what are you waiting for? Go make something cool with it!
