How do you create utility function files with no default export

[tranquil finch]

I'm building my app locally and am running into an issue where the compiler complains about a file not having a default export. I managed to solve the issue in one of them by simply adding default

export default ()=>{
//...
}```

My `nodemailer.ts` is completely blank. Do I still need an `export default`? Do I just do a simple 
```tsx
export default {}

for the compiler to stop complaining? Is this a good work around?

You should only add files that are expected to be pages in the pages directory, everything else should be outside otherwise Next will try to create a routable page to the file

I thought it would be good practice to place lib folders alongside components, but I guess how NextJS is implemented is to create paths like you mentioned if they're in the pages directory.
