Example expo app working inside a cedar project.

Some issues I found that should be looked into:

• When using import { RedwoodApolloProvider } from '@cedarjs/web/apollo'

ERROR ReferenceError: Property 'RWJS_ENV' doesn't exist, js engine: hermes
WARN Route "./(tabs)/\_layout.tsx" is missing the required default export. Ensure a React component is exported as default.
ERROR ReferenceError: Property 'RWJS_ENV' doesn't exist, js engine: hermes
WARN Route "./(tabs)/index.tsx" is missing the required default export. Ensure a React component is exported as default.
ERROR ReferenceError: Property 'RWJS_ENV' doesn't exist, js engine: hermes
WARN Route "./\_layout.tsx" is missing the required default export. Ensure a React component is exported as default.
ERROR Warning: Invalid prop `style` supplied to `React.Fragment`. React.Fragment can only have `key` and `children` props.

Fixed by passing graphQLClientConfig={{ uri: process.env.EXPO_PUBLIC_API_URL! }} to RedwoodApolloProvider

• When using import { useQuery } from '@cedarjs/web'

 ERROR  Warning: Error: You must register a useQuery hook via the `GraphQLHooksProvider`

This error is located at:

  22 |
  23 | export default function HomeScreen() {
> 24 |   const { data, loading, error } = useQuery(QUERY)
     |                                            ^
  25 |

Fixed it by importing useQuery from @apollo/client

• When using gql to define queries

 ERROR  ReferenceError: Property 'gql' doesn't exist, js engine: hermes

Fixed it by importing gql from @apollo/client

• After a successful login often times the user credentials are not saved and you have to retry login multiple times until it succeeds

• To get @cedarjs/auth-dbauth-web to work properly you have to define some global variables

globalThis.RWJS_ENV = {
  RWJS_API_GRAPHQL_URL: process.env.EXPO_PUBLIC_RWJS_API_GRAPHQL_URL!,
  RWJS_API_URL: process.env.EXPO_PUBLIC_API_URL!,
}
globalThis.RWJS_API_GRAPHQL_URL = process.env.EXPO_PUBLIC_RWJS_API_GRAPHQL_URL!
globalThis.RWJS_API_URL = process.env.EXPO_PUBLIC_API_URL!
