@juanita_b_sutton a lot of stuffs ! For example, in my react starterkit, i'm using 30+ packages by default, including babel, react and react-*, redux, express, socket.io, etc, and 10+ packages for the stack (transpiling, building, testing, etc), with ssr and code splitting support. With my growing codebase, i've got all i need but this goes much further than just making possible to work on a frontend app like Angular: by adding/removing some packages (like react ^^), i've a rest api server or a websocket middleware or a redis queue worker, etc. Packages don't do the ultimate trick, my codebase organize them and their usage in the stack for writing less code as possible. (Sorry for typos...)
