All these packages don't take much memory. Also tree shaking is a thing. For example, one of the projects I currently work on has over 5 gigs of dependencies, but once I compile it for production, the whole code based is mere 3 megs and that's including inlined styles and icons. The code itself is pretty much non-existent.
On the other hand I have 100KB of text translations just for the English language alone. Because there's shit loads of text. And over 100MB of images, which are part of the build. And then there's a remote storage with gigabytes of documents.
Even if I double the code base by copy pasting it will be a drop in a bucket.
