});

export const { signIn, signUp, useSession } = createAuthClient();

import { PrismaClient } from '@/generated/prisma';

const prisma = new PrismaClient();

export const auth = betterAuth({
  database: prismaAdapter(prisma, {
    provider: 'postgresql',
  }),
  socialProviders: {
    github: {
      clientId: process.env.GITHUB_CLIENT_ID as string,
