This is a detailed reference for the `StackApp` object. If you're looking for a more high-level overview, please read the [respective page in the Concepts section](../../concepts/stack-app.mdx).

## Overview

- [StackServerApp](#stackserverapp) - Server-level permissions with full access

# StackClientApp

A [`StackApp`](../../concepts/stack-app.mdx) with client-level permissions. It contains most of the useful methods and hooks for your client-side code.

{/* IF_PLATFORM: react-like */}
Most commonly you get an instance of `StackClientApp` by calling [`useStackApp()`](../hooks/use-stack-app.mdx) in a Client Component.

## Constructor

<MethodSection>
<MethodLayout>
  <MethodContent>

Creates a new `StackClientApp` instance.

Because each app creates a new connection to Stack Auth's backend, you should re-use existing instances wherever possible.

{/* IF_PLATFORM: react-like */}
<Info type="info">
This object is not usually constructed directly. More commonly, you would construct a [`StackServerApp`](#stackserverapp) instead, pass it into a [`<StackProvider />`](../../components/stack-provider.mdx), and then use `useStackApp()` hook to obtain a `StackClientApp`.

The [setup wizard](../../getting-started/setup.mdx) does these steps for you, so you don't need to worry about it unless you are manually setting up Stack Auth.

If you're building a client-only app and don't have a [`SECRET_SERVER_KEY`](../../rest-api/overview#should-i-use-client-or-server-access-type), you can construct a `StackClientApp` directly.

# StackServerApp

Like `StackClientApp`, but with [server permissions](../../concepts/stack-app.mdx#client-vs-server). Has full read and write access to all users.

<Info type="warning">
Since this functionality should only be available in environments you trust (ie. your own server), it requires a [`SECRET_SERVER_KEY`](../../rest-api/overview.mdx).
In some cases, you may want to use a [`StackServerApp`](#stackserverapp) on the client; an example for this is an internal dashboard that only your own employees have access to.
We generally recommend against doing this unless you are aware of and protected against the (potentially severe) security implications of 
exposing [`SECRET_SERVER_KEY`](../../rest-api/overview.mdx) on the client.
