📄 Description

Hi I got stuck with the expo intergration and it took me a while to figure it out, but the issue is that the baseUrl localhost:8081 (lets pretend thats where your server is), of course doesn't work on the phone (server is not running on the phone)! This pr adds an accordion explanation to help other people get the correct baseUrl with a function.

Especially helpful, since there is no error message for when the server url is not found.

import Constants from "expo-constants";

export const getBaseUrl = () => {
  const debuggerHost = Constants.expoConfig?.hostUri;
  const localhost = debuggerHost?.split(":")[0];

  if (!localhost) {
   // Production
   return "https://[your-better-auth-backend-url]";
  }
  // Development
  return `http://${localhost}:8081`; // this should be the port of your Better Auth backend
};
