<Info>
Welcome to the Next.js SDK setup guide. If you're looking for guides for other frameworks, check out the [React SDK Setup](/docs/react/getting-started/setup), or the [JavaScript SDK Setup](/docs/js/getting-started/setup).
</Info>

## Setup

Before getting started, make sure you have a [Next.js project](https://nextjs.org/docs/getting-started/installation) using the app router, as Stack Auth does not support the pages router.

We recommend using our **setup wizard** for a seamless installation experience. The wizard automatically detects your project structure and walks you through the setup process. If you encounter any issues with the wizard, you can follow our manual installation steps instead.

  <TabsContent value="wizard">
    <Steps>
      <Step>
      ### Run installation wizard
      </Step>
      Run Stack's installation wizard with the following command:

      ```sh title="Terminal"
      npx @stackframe/init-stack@latest
      ```

      <Step>
      ### Update API keys
      </Step>
      Then, create an account on [the Stack Auth dashboard](https://app.stack-auth.com/projects), create a new project with an API key, and copy its environment variables into the `.env.local` file of your Next.js project:

      ```sh title=".env.local"
      NEXT_PUBLIC_STACK_PROJECT_ID=<your-project-id>
      NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY=<your-publishable-client-key>
      STACK_SECRET_SERVER_KEY=<your-secret-server-key>
      ```

      <Step>
      ### Done!
      </Step>
      That's it! The following files should have been created or updated in your project:

      - `app/handler/[...stack]/page.tsx`: This file contains the default pages for sign-in, sign-out, account settings, and more. If you prefer, later you will learn how to [use custom pages](../customization/custom-pages.mdx) instead.
      - `app/layout.tsx`: The layout file was updated to wrap the entire body with `StackProvider` and `StackTheme`.
      - `app/loading.tsx`: If not yet found, Stack automatically adds a Suspense boundary to your app. This is shown to the user while Stack's async hooks, like `useUser`, are loading.
      - `stack.ts`: This file contains the `stackServerApp` which you can use to access Stack from Server Components, Server Actions, API routes, and middleware.
    </Steps>

    <Info>
      Note: The setup wizard also supports existing, complicated projects. Cases where manual installation is necessary are rare.
    </Info>

    If you are struggling with the setup wizard, please reach out to us on our [Discord](https://discord.stack-auth.com) first, where we'll be happy to help you.
    <Steps>
      <Step>
      ### Install npm package
      </Step>
      First, install Stack with npm, yarn, or pnpm:

      ```bash title="Terminal"
      npm install @stackframe/stack
      ```

      <Step>
      ### Create API keys
      </Step>
      If you haven't already, [register a new account on Stack](https://app.stack-auth.com/handler/sign-up). Create a project in the dashboard, create a new API key from the left sidebar, and copy the project ID, publishable client key, and secret server key into a new file called `.env.local` in the root of your Next.js project:

      ```sh title=".env.local"
      NEXT_PUBLIC_STACK_PROJECT_ID=<your-project-id>
      NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY=<your-publishable-client-key>
      STACK_SECRET_SERVER_KEY=<your-secret-server-key>
      ```

      <Step>
      ### Create `stack.ts` file
      </Step>
      Create a new file `stack.ts` in your root directory and fill it with the following:
      
      ```tsx title="stack.ts"
      import "server-only";
      import { StackServerApp } from "@stackframe/stack";

      export const stackServerApp = new StackServerApp({
        tokenStore: "nextjs-cookie", // storing auth tokens in cookies
      });
      ```
    
      This will read the environment variables automatically and create a server app that you can later use to access Stack from your Next.js server.
      
      Check out the [`StackServerApp` documentation](../sdk/objects/stack-app.mdx) to learn more about its other options.

      <Step>
      ### Create Stack handler 
      </Step>
      Create a new file in `app/handler/[...stack]/page.tsx` and paste the following code: 

      ```tsx title="app/handler/[...stack]/page.tsx"
      import { StackHandler } from "@stackframe/stack";
      import { stackServerApp } from "@/stack";

      export default function Handler(props: unknown) {
        return <StackHandler fullPage app={stackServerApp} routeProps={props} />;
      }
      ```

      This will create pages for sign-in, sign-up, password reset, and others. Additionally, it will be used as a callback URL for OAuth. You can [replace them with your own pages](../customization/custom-pages.mdx) later.

      <Step>
      ### Add StackProvider to `layout.tsx`
      </Step>
      In your `app/layout.tsx`, wrap the entire body with a `StackProvider` and `StackTheme`. Afterwards, it should look like this:

      ```tsx title="app/layout.tsx"
      import React from "react";
      import { StackProvider, StackTheme } from "@stackframe/stack";
      import { stackServerApp } from "@/stack";

      export default function RootLayout({ children }: { children: React.ReactNode }) {
        return (
          <html lang="en">
            <body>
              <StackProvider app={stackServerApp}>
                <StackTheme>
                  {children}
                </StackTheme>
              </StackProvider>
            </body>
          </html>
        );
      }
      ```
      
      <Step>
      ### Add Suspense boundary
      </Step>
      By default, Stack uses [`Suspense`](https://react.dev/reference/react/Suspense) to handle loading states. To show a loading indicator while Stack is fetching user data, make sure there is a `loading.tsx` file in your `app` directory:

      ```tsx title="app/loading.tsx"
      export default function Loading() {
        // You can use any loading indicator here
        return <>
          Loading...
        </>;
      }
      ```

      <Step>
      ### Done!

## Post-setup

That's it! Stack is now configured in your Next.js project. If you start your Next.js app with `npm run dev` and navigate to [http://localhost:3000/handler/signup](http://localhost:3000/handler/sign-up), you will see the sign-up page.

<div className="stack-white-image-showcase stack-350h">
  <img src="/imgs/sign-in.png" alt="SignIn" />
</div>

After signing up/in, you will be redirected back to the home page. We will show you how to add user information to it in the next section. You can also check out the [http://localhost:3000/handler/account-settings](http://localhost:3000/handler/account-settings) page which looks like this:

![Stack account settings page](/imgs/account-settings.png)


## Next steps

Next up, we will show you how to [retrieve and update user information](./users.mdx), and how to [protect a page](./users.mdx#protecting-a-page) from unauthorized access.

<Info>
Welcome to the React SDK setup guide! If you're looking for guides for other frameworks, check out the [Next.js SDK Setup](/docs/next/getting-started/setup), or the [JavaScript SDK Setup](/docs/js/getting-started/setup).
</Info>

Before getting started, make sure you have a [React project](https://react.dev/learn/creating-a-react-app) setup. We show an example here of a Vite React project with React Router.

<Steps>
  <Step>
    ### Install npm package
  </Step>

  ```bash title="Terminal"
  npm install @stackframe/react
  ```

  <Step>
    ### Create API keys
  </Step>

  If you haven't already, [register a new account on Stack](https://app.stack-auth.com/projects), create a project in the dashboard, create a new API key from the left sidebar, and copy the project ID, publishable client key, and secret server key into a new file called `.env.local` in the root of your React project:

  <Step>
    ### Create `stack.ts` file
  </Step>
  Create a new file `stack.ts` in your root directory and fill it with the following Stack app initialization code:

  ```tsx title="stack.ts"
  import { StackClientApp } from "@stackframe/react";
  import { useNavigate } from "react-router-dom";

  export const stackClientApp = new StackClientApp({
    // You should store these in environment variables based on your project setup
    projectId: "your-project-id",
    publishableClientKey: "your-publishable-client-key",
    tokenStore: "cookie",
    redirectMethod: {
      useNavigate,
    }
  });
  ```

  <Step>
    ### Update `App.tsx`
  </Step>

  Update your `App.tsx` file to wrap the entire app with a `StackProvider` and `StackTheme` and add a `StackHandler` component to handle the authentication flow.

  ```tsx title="App.tsx"
  import { StackHandler, StackProvider, StackTheme } from "@stackframe/react";
  import { Suspense } from "react";
  import { BrowserRouter, Route, Routes, useLocation } from "react-router-dom";
  import { stackClientApp } from "./stack";

  function HandlerRoutes() {
    const location = useLocation();
    
    return (
      <StackHandler app={stackClientApp} location={location.pathname} fullPage />
    );
  }

  export default function App() {
    return (
      <Suspense fallback={null}>
        <BrowserRouter>
          <StackProvider app={stackClientApp}>
            <StackTheme>
              <Routes>
                <Route path="/handler/*" element={<HandlerRoutes />} />
                <Route path="/" element={<div>hello world</div>} />
              </Routes>
            </StackTheme>
          </StackProvider>
        </BrowserRouter>
      </Suspense>
    );
  }
  ```
  
  <Step>
    ### Done!
  </Step>

  That's it! Stack is now configured in your React project. If you start your React app and navigate to [http://localhost:5173/handler/sign-up](http://localhost:5173/handler/sign-up), you will see the sign-up page.


  <div className="stack-white-image-showcase stack-350h">
    <img src="/imgs/sign-in.png" alt="SignIn" />
  </div>

  After signing up/in, you will be redirected back to the home page. We will show you how to add user information to it in the next section. You can also check out the [http://localhost:5173/handler/account-settings](http://localhost:5173/handler/account-settings) page which looks like this:

  ![Stack account settings page](/imgs/account-settings.png)

{/* ELSE_IF_PLATFORM python */}

<Info>
Welcome to the Python setup guide. If you're looking for guides for other frameworks, check out the [Next.js SDK Setup](/next/getting-started/setup), [React SDK Setup](/react/getting-started/setup), or the [JavaScript SDK Setup](/js/getting-started/setup).
</Info>

Our recommended way to use Stack Auth with Python is with the [REST API](../rest-api/overview.mdx). It provides a fully documented way to interact with Stack Auth from any Python framework, including Flask, FastAPI, and Django.

For the purpose of this guide, we will use the `requests` library to make HTTP requests to the Stack Auth API. If you haven't already, you can install it in your environment with `pip install requests`.

<Steps>
  ### Create API keys

  First, create an account on [the Stack Auth dashboard](https://app.stack-auth.com/projects), and copy your project ID, publishable client key, and secret server key into a safe place (eg. environment variables).

  From there, you can access them in your Python code. You can then read them like this:

  ```python
  import os

  stack_project_id = os.getenv("STACK_PROJECT_ID")
  stack_publishable_client_key = os.getenv("STACK_PUBLISHABLE_CLIENT_KEY")
  stack_secret_server_key = os.getenv("STACK_SECRET_SERVER_KEY")
  ```

  ### Make a request

  Next, create a helper function to make requests to the Stack Auth API:

  ```python
  import requests

  def stack_auth_request(method, endpoint, **kwargs):
    res = requests.request(
      method,
      f'https://api.stack-auth.com/{endpoint}',
      headers={
        'x-stack-access-type': 'server',  # or 'client' if you're only accessing the client API
        'x-stack-project-id': stack_project_id,
        'x-stack-publishable-client-key': stack_publishable_client_key,
        'x-stack-secret-server-key': stack_secret_server_key,  # not necessary if access type is 'client'
        **kwargs.pop('headers', {}),
      },
      **kwargs,
    )
    if res.status_code >= 400:
      raise Exception(f"Stack Auth API request failed with {res.status_code}: {res.text}")
    return res.json()

  print(stack_auth_request('GET', '/api/v1/projects/current'))
  ```
  ### Retrieve the access tokens

  If you're building a backend server, most likely you'll want to use the currently signed in user's access token. Most normally, you would send this with all your requests to the backend in an HTTP header.

  In Stack Auth's JavaScript SDK, you can retrieve the access token [from the `stackClientApp` object](/sdk/types/user#currentusergetauthjson). Then, you can use said access token to make requests to Stack Auth:

  ```python
  access_token = # access token retrieved from the JavaScript SDK

  print(stack_auth_request('GET', '/api/v1/users/me', headers={
    'x-stack-access-token': access_token,
  }))
  ```

  ### Done!
</Steps>

## Next steps

Check out the [REST API documentation](../rest-api/overview.mdx) to learn more about the available endpoints and how to use them in your Python application.
