160K total is impressive. most landing pages i see are shipping 2-3MB of js before the first paint. the "write your own code" approach gets laughed at but when you actually do it the result is faster, easier to debug, and you dont wake up one morning to find out one of your 200 dependencies got compromised.

Wait till I tell those people we keep all our dependencies (js and backend) in our own git repo.

Updating dependencies is a task a person does, followed by committing the changes to the repo.

I am aware a lot of these ideas are heretical to a lot of software developers these days.
