Hey friends So today. I just want to mention something that I've been

working on for the last couple days. So if you didn't know node version 10is the last version of node that so does not support native ECMAScriptmodules without a flag. So you can use ECMAScript modules with node version10, but you need to pass it a flag version 12 and above I'll do not requirea flag they just support a native ESM out of the box.

And what's exciting about this is it means that package authors can start

using native ES module.'s and and we can consume them as native modules andwe don't have to compile down or compile away those ES modules. This is agood thing but it also comes with a fair number of complications.

For one thing we're not there are interesting semantics with the way that

ESM works native ESM. For example, you cannot use require for a native ESmodule. So, you can't just require a library or another module that you'vewritten. You.Have to use an import statement. Now, you're probably workingin if you're working in a node application, you're probably working in onethat is not using native ESM if you if you are using native that's awesomegood for you, but most of us probably aren't.

So we're either compiling our import statements to require or we're

requiring writing require ourselves. And so if you want to start usingpackages that are built with native ESM, then you're going to need to dothings a little bit differently. So you.Can't use an import statement in acommon JS module.

So a non-ESM module. And so the only way to get a ESM module into your

common JS module is by using a dynamic import statement, which looks like afunction when you call import. It's an asynchronous operation, so you needto use asynchle weight. Luckily for us node version, or yeah recently atsome point.

I think version 14, we know have support for root or or module async await.

Unfortunately,That only works in native ESM modules So if you want to use aif you're writing a common JS module and you want to import a ESM modulethe only way to do it is to use a dynamic import and you have to it'sasynch weight and so or or promise I guess.

And so, you have to write an async function to be able to import anything

from ESM. There's I'm going to need to like write a blog post about thisand stuff because there are a couple of interesting things here. It's goingto be a little bit painful, but I think in the end we're all going to bemuch.

Better off just going full native ESM. I hope that's interesting. Bye.
