move configs into their own file

[oliviamriley]

rn all the default configs are sitting in index.js and it makes it less readable.

we should move them to a separate file (it could just be json, or maybe js and use export or smth).

so node.js doesn't natively support import rn, which means we can't just use import/export.
this is the problem with node!! it wasn't meant to be a server-side language so stuff like this is just tacked on.

until node adds this support, we need to either read from JSON (which is ugly and not worth it) or use a transpiler. personally, i don't think this is worth adding another dev dependency when it was supposed to make development easier . im marking this wontfix until node updates.
