Follow this advice! It's not a genuine practice, because it adds a lot of work to your development dependencies (TS, Biome, eslint, etc.), and your downstream users too!

NEVER buy anything Adobe. Adobe is the example of what greed does to a company. No matter how outraged people are; no matter that the FTC is suing Adobe and executives for this practice; Adobe keeps doing it. I got scammed by this same practice in 2020 the same way: I switched to Affinity instead.

That's right, type-aware lint rules without the TypeScript compiler! It's been a wild ride, but we arrived there. Enjoy!

We tell users that they shouldn't use a dependency of another dependency. But can we talk about re-export or types from a dependency? In a way, isn't it kinda-kinda the same? Only that the library author does this, and can breakages too.

Great write up! Knockout.js is missing, which is the framework that inspired Angular.js. There's marionette.js too, which is an extension of backbone.js; that's usually used at enterprise levels. And where's Bower?? The package manager created by twitter. Damn the nostalgia hit hard

All right, we are very close. @biomejs.dev v2 is very stable now. There are no memory leaks, no major regressions, and still good DX. Multi-file analysis took a while, and I hope the next major (if ever) will take less time to get out. Now to polish docs, do some more testing, and we're ready!
