# JavaScript SDKs & Samples

> Auth0 JavaScript SDKs make it easy for developers to integrate with and secure AI agent workflows.

## Auth0 SDKs

Updated Auth0 SDKs to secure AI agent workflows:

### [Next.js](https://github.com/auth0/nextjs-auth0)

This SDK streamlines integrating Auth0 authentication and authorization services into Next.js applications. It supports:

* User authentication
* Tools for getting access tokens for supported social and enterprise identity providers

```bash wrap lines theme={null}
npm install @auth0/nextjs-auth0
```

### [Node.js](https://github.com/auth0/node-auth0)

This library streamlines integrating Auth0's authentication and authorization services into Node.js applications. It supports:

* User authentication
* Tools for signing up users, managing user profiles, and securing API endpoints.

```bash wrap lines theme={null}
npm install auth0
```

### [Auth0 Fastify SDK](https://www.npmjs.com/package/@auth0/auth0-fastify)

This SDK streamlines integrating Auth0 authentication and authorization services into Fastify applications. It supports:

* User authentication
* Tools for getting access tokens to call first-party APIs

```bash wrap lines theme={null}
npm i @auth0/auth0-fastify
```

## Auth0 AI SDKs

Auth0 AI SDKs to streamline integrating your application with popular agentic frameworks:

### [Auth0 AI SDK](https://github.com/auth0/auth0-ai-js)

This SDK provides base abstractions for authentication and authorization in AI applications. It supports:

* Asynchronous user authentication using the [Client Initiated Backchannel Authentication (CIBA)](https://openid.net/specs/openid-client-initiated-backchannel-authentication-core-1_0.html) protocol
* [OpenFGA-based](https://openfga.dev/) filter for RAG

```bash wrap lines theme={null}
npm install @auth0/ai
```

### [Auth0 AI Components](https://github.com/auth0/auth0-ai-js/tree/main/packages/ai-components)

This library helps to set up the React components that can be used in AI applications using AI Identity for B2B. The components are styled using [Tailwind CSS](https://tailwindcss.com/). It supports:

* Tools for getting access tokens for supported social and enterprise identity providers

```bash wrap lines theme={null}
npx @auth0/ai-components add TokenVault
```

### [Redis Store for Auth0 AI](https://github.com/auth0/auth0-ai-js/tree/main/packages/ai-redis)

This SDK provides a secure Redis-based data store implementation for use with the Auth0 AI SDKs. It supports:

* Securely encrypting data before storing it in Redis
* Organizing keys using namespaces
* Setting expiration times for stored data

```bash wrap lines theme={null}
npm install @auth0/ai-redis
```
