I love Webpack, but it does feel like I'm copying and pasting bits from the web & hoping for the best sometimes.

I think long term I'll move to something like Encore as it has way nicer safety rails.

Then you should really like using Symfony.

Hah! I do like what they're doing with Webpack, I'd love to bring it over to the Rails world.

I used webpack (in fact we have a project that remains with webpack) but we moved to Parcel bundler on the rest of the projects.

can you please explain why you moved your projects into the parcel, what benefits are you getting using parcel

With parcel you don't have to configure almost anything, it detects what you use inside your project and add necessary packages out of the box

If you want to know more here's the official webpage and I wrote this article using Parcel bundler. It's even better now than when I wrote the article so you must take a look at it :)

I think we will eventually end as we start, pulling all the modules from an external CDN, and writing only the modules we need to make the app work. Decorators, JSX, Vue Files, all of them will eventually be replaced with native JS again. :P

I scrolled down to see the answers, then refreshed, then hard-refresh.

I guess life is about finding answers yourself. All right then!
