I think this is saying it's:

Axios, like Express, is something I'm shocked to see used in any modern codebase. I loved both in the 2010s. In JS/TS-land there are much simpler and better options these days. Depending on Axios suggests the devs don't know how to use fetch. I can't think of another reason it would be a necessary dependency
