Axios would've added some more to the dreaded bundle size lol.
Yea, thats true. Web dev sucks because of that, at least on the backend I don't have to worry so much about the size of npm modules since its a install once thing(though minimal dependencies is better for many reasons).
Needing to care about dependency size is just one of the things on a long list that makes web dev so annoying.
Just write everything yourself, no need for anything extra then :P
