Automagically installing dependencies that it fails to `require()` seems way out of scope for a bundler. Or managing Rust toolchains. Or a bunch of hard-coded rules that hard-exclude compiling stuff in `node_modules`. Unless they're in symlinks (presumably for Yarn workspaces?). And so on.
I started with Grunt. Then came Gulp, webpack, and a couple of others. They all do pretty much the same thing, and yet apparently someone has come up with a new one called parcel.
Do they do this shit to make nice CV's so they can land FAANG jobs?
Everything was easier back when we used to use FTP to upload CSS and JS files to sit alongside index.html or index.php.
EDIT: I just googled and the first result is parceljs.org, but that one is blank with a BLM logo on it. Is there another site?
