User.Root · Scope

User.RootSays which auth the User parts below read, and whether they may do without it. The parts need no root: left out, they read the nearest auth root's config, or "default", and render nothing without auth. `<User.Root enabled="optional">` is for the one who wants that said in the code.

Installation

Choose what your component needs. Run these commands in an initialized Next.js app.

Before you start

The steps below run in a Next.js app with shadcn set up (it has a components.json). In an existing Next.js app, such as one from create-next-app, set shadcn up first:

npx shadcn@latest init -t next -b base -p nova

Or start fresh: the slices CLI creates the app and sets it up.

npx slices.sh install

Install the service registry

Adds services/index.ts, which import "@/services" loads. A provider setup writes the same file, so skip this if your app has one.

npx add services

Install the headless library

npm

Add the React parts to your app, then compose them with your own elements.

npm install @slices.sh/auth@^0.1.10

Import from @slices.sh/auth/headless.

Install the service

Connect the parts to a provider. Skip this step if this service is already configured in your app.

Provider

Database

Account capabilities

passkeystwo-factororganizationspassword-reset

npx add auth.betterauth --auth-methods google

Adds service configuration and API routes to your app, with the provider dependencies. For a headless composition, add import "@/services" after "use client".

The slices CLI installs the service and provisions its required resources in one command.

Set BETTER_AUTH_URL to your app origin. Memory is for local development; use a persistent database for deployment. Neon and Supabase also require the migration script printed by the installer.

Provider setup notes

BETTER_AUTH_SECRET signs every session and is generated into .env.local while this installs (32 random bytes, base64, nothing leaves the machine). Changing it signs everyone out; in production set the same one on every instance.
The public origin (OAuth callbacks, the passkey domain) is the one each request comes to in development, and the deployment's own on Vercel. Elsewhere, or behind a proxy or a custom domain, set BETTER_AUTH_URL, such as https://acme.com.

Start small

Parts bring the behavior. Use their default elements, or supply your own with render.

example.tsx

"use client"import "@/services"import { Sessions } from "@slices.sh/auth/headless"export function Example() {  return (    <Sessions.Root>      <Sessions.Item>        <Sessions.Current>This device</Sessions.Current>        <Sessions.ActionTrigger>Sign out device</Sessions.ActionTrigger>        <Sessions.ActionDialog>          <Sessions.Confirm>Confirm</Sessions.Confirm>          <Sessions.Cancel>Cancel</Sessions.Cancel>        </Sessions.ActionDialog>      </Sessions.Item>      <Sessions.Empty>No sessions.</Sessions.Empty>      <Sessions.Error />    </Sessions.Root>  )}

Requires an authenticated account. Organization controls also require organizations and the appropriate role.

API reference

Every public part used by this experience is listed below. Gates render children without adding an element. Element parts accept native element props and render; function children receive the state declared in their props. Scopes provide context rather than a visual element.

When something is missing

No service configuration: Install the auth setup below and import "@/services". Required service roots report missing setup; gates do not replace that configuration.
Missing capability or parent scope: Follow each part’s context requirements and the example composition. Capability-aware controls hide when the provider cannot perform their action.
