Setup Better Auth

Initialize Better Auth with full configuration for your React application.

Instructions

1. Install Dependencies:

   bun add better-auth
   bun add -D @types/better-auth
   

2. Create Server Configuration at src/lib/auth.ts:

   import { betterAuth } from 'better-auth'
   import { prismaAdapter } from 'better-auth/adapters/prisma'
   import { prisma } from './prisma'
   
   export const auth = betterAuth({
     database: prismaAdapter(prisma, {
       provider: 'postgresql', // or 'mysql', 'sqlite'
     }),
   
     emailAndPassword: {
       enabled: true,
       requireEmailVerification: true,
       password: {
         minLength: 12,
         requireUppercase: true,
         requireNumber: true,
       },
       sendVerificationEmail: async (user, token, url) => {
         // TODO: Implement email sending
         console.log('Verification URL:', url)
       },
       sendResetPasswordToken: async (user, token, url) => {
         // TODO: Implement email sending
         console.log('Reset URL:', url)
       },
     },
   
     session: {
       expiresIn: 60 * 60 * 24 * 7, // 7 days
       updateAge: 60 * 60 * 24,     // Extend daily
       cookie: {
         httpOnly: true,
         secure: process.env.NODE_ENV === 'production',
         sameSite: 'lax',
       },
     },
   
     // Add social providers if requested
     socialProviders: {
       // Configured based on --providers flag
     },
   
     // Add plugins if requested
     plugins: [
       // Added based on --2fa and --passkeys flags
     ],
   })
   
   export type Auth = typeof auth
   

3. Create Auth Client at src/auth/client.ts:

   import { createAuthClient } from 'better-auth/react'
   import type { Auth } from '@/lib/auth'
   
   export const authClient = createAuthClient<Auth>({
     baseURL: import.meta.env.VITE_API_URL || 'http://localhost:3000',
   })
   
   export const {
     signIn,
     signUp,
     signOut,
     useSession,
     getSession,
     resetPassword,
     verifyEmail,
   } = authClient
