@polotek @zkat @slightlyoff That site seems down right now, so I can't see it, but I'm pretty sure this is Angular.js. You're probably interested in `@angular/core`.
Also I'm pretty sure Angular publishes multiple bundles (ESM / flattened ESM) for build performance, so the number is likely to be quite inflated even though no user would actually be downloading that much.
Someone else already mentioned that this doesn't take tree shaking into account, so I'm really not sure how much value these numbers provide. Better metrics exist.
