SignedIn

Overview

SignedIn renders children only when useAuth reports a signed-in user. While the session is loading it renders nothing (no built-in skeleton). For loading UI or email-verified branches, use Show.

Preview

Interactive preview requires JavaScript.

Install

npx @simpleauthjs/react add session

Props

Name	Type	Required	Description
`children`	`ReactNode`	Yes	Shown when the user has an active session.

Usage

"use client"

import { SignedIn } from "@/components/simpleauth"

export function UserMenu() {
  return (
    <SignedIn>
      <a href="/account">Account</a>
    </SignedIn>
  )
}

Source

SignedIn is generated with the session feature. The preview below lists the session-related files the CLI writes (including signed-in.tsx, use-auth.ts, and use-current-user.ts).
