• export function as default
• makeServer function take one argument

Thanks for the PR! Happy to include the default export in the example. What’s the rationale behind the config argument? It isn’t used in the example, right?

What’s the rationale behind the config argument?

Newer version of mirage (0.1.48) requires one argument. Without the argument, user encounter the follow error.

Uncaught Error: Assertion Failed: Mirage config default exported function must at least one parameter

Oof, that’s not great but 🤷‍♂️ Thanks for taking the time to update the README!
