We use Better Auth (better-auth) for identifying users.
lib/auth-client.ts exports authClient.lib/auth.ts exports auth.Use authClient for signing in, signing out, and checking session state in Client Components.
import { authClient } from "@/lib/auth-client";
// Sign In
await authClient.signIn.email({
email,
password,
});
// Social Sign In
await authClient.signIn.social({
provider: "google",
callbackURL: "/onboarding",
});
// Sign Out
await authClient.signOut();
Use auth.api.getSession for protecting API routes or Server Actions.
import { auth } from "@/lib/auth";
import { headers } from "next/headers";
const session = await auth.api.getSession({
headers: await headers()
});
if (!session) {
return new Response("Unauthorized", { status: 401 });
