All SDK imports in the framework code have been updated according to the new code organization.

This is where we set the framework runtime's condition string, thus gaining access to the SDK's private API.

// These packages rely on a single instance per page. Not dedpuing them
// causes runtime errors (e.g., hook rule violation in react, QueryClient
// instance error in react-query, Invariant Error in react-router-dom).

I've updated all the import paths inside the SDK have been converted from package imports to relative imports (also accounting for the updated paths).

import { api, handleApiError } from 'wasp/client/api'
import { HttpMethod } from 'wasp/client'
import type { AuthUser } from './types'

This how we expose the SDK's private API to the framework, while hiding it from the user.

Unfortunately, we can't do:

"exports": {
  "client-runtime": {
    // private API
  },
  "default": {
    // public API
  }

Because once Vite finds an object with a matching condition, it won't trace back if it doesn't find a required symbol inside it:

Vite has a list of "allowed conditions" and will match the first condition that is in the allowed list.

Which means we would have to repeat the entire public API twice.

"exports": {
  "client-runtime": {
    // private API
    // public API
  },
  "default": {
    // public API
  }

It isn't quite as nice, but works. We can still decide which approach do we want to take.

Great stuff! I didn't know that exports API worked this way. I always thought that the import and require were the only options.

{=! todo(filip): Check all exports when done with SDK generation =}
{=! Some of the statements in the comments might become incorrect. =}
{=! "our code" means: "web-app", "server" or "SDK", or "some combination of the three". =}
