New blog post: "Let’s learn how modern JavaScript frameworks work by building one" https://nolanlawson.com/2023/12/02/lets-learn-how-modern-javascript-frameworks-work-by-building-one/

Some step-by-step instructions on how to build a new JavaScript framework, if you're so inclined. Or just my way of learning how they all work!

Let’s learn how modern JavaScript frameworks work by building one

In my day job, I work on a JavaScript framework (LWC). And although I’ve been working on it for almost three years, I still feel like a dilettante. When I read about what’s going on in …

@nolan I’ve spent the last couple months building my own view engine (yeah, I know, there’s a lot of them) and this post is an interesting comparison to what I’ve done.

I’m not using cloned templates and not sure if I’d get those performance benefits. But I’m also using TSX so I’m not starting with template strings either.

@nolan If you are curious about someone else’s crazy take in this space, and I would certainly appreciate early feedback: https://github.com/WorldMaker/butterfloat

Also I did some magic in the TSX types that I’m proud of. Think I beat React’s DX at a fraction of the labor to do it.

@nolan this rules! I'm totally building a toy framework right now as well- always amazed at your ability to put all this tinkering into blog posts.

@potch Thank you! I had some fun tinkering with this, so I enjoyed blogging about the thought process. 🙂
