Guides

TBD: we might write guides like this?

1. Define a helper method a typescript or javascript

   collections/example/helper.ts

   export async function authFor(env: string) {
     return `auth-for-${env}`;
   }

2. import the helper method and call it.

   collections/example/products.https

   import:
     ./helper.ts:
       - authFor
   >>>
   POST https://example.com/products
   Authorization: {{ @auth = authFor(env) }}
