# Cerbos authorization for Nuxt

Add policy-based authorization to Nuxt server routes, middleware, and API endpoints using Cerbos. Enforce access control in your Nitro server layer without scattering permission logic across your application.

- **Authorize server routes** — Enforce fine-grained permissions in Nitro server handlers and API routes without embedding authorization logic in each endpoint
- **Leverage request context** — Pass user identity, resource attributes, and request metadata from Nuxt server middleware to Cerbos for context-aware authorization decisions
- **Centralize access control** — Define authorization rules in YAML policies instead of spreading permission checks across server routes, middleware, and composables

## How Cerbos works with Nuxt

Building authorization logic inside Nuxt quickly becomes a maintenance burden. Hard-coded role checks scatter across controllers and middleware, and every permission change requires a code deploy.

Cerbos replaces scattered authorization logic with a single API call. You define fine-grained policies in YAML, and the Cerbos PDP evaluates them at request time using roles, attributes, and any context you provide.

With Cerbos your Nuxt application stays focused on business logic while authorization policies evolve independently, managed by product or security teams without touching code.

### How Cerbos works with Nuxt

1. **Install the Cerbos SDK in your Nuxt project.** Add the JavaScript SDK as a dependency and configure a Cerbos client, typically as a Nuxt server plugin or utility module.
1. **Call Cerbos from server middleware or route handlers.** In your Nitro server routes and middleware, extract the authenticated user and call the Cerbos PDP to check whether the request is allowed before processing it.
1. **Define authorization policies in YAML.** Write resource and principal policies that capture your access control rules, including roles, attributes, and conditions. Store them alongside your code and version them in git.
1. **Cerbos evaluates policies at request time.** Every authorization check is evaluated against the latest policies with sub-millisecond latency. Update rules without redeploying your Nuxt application.

## FAQ

### How do I integrate Cerbos with Nuxt?

Install the Cerbos JavaScript SDK and call the Cerbos PDP from your Nuxt server routes or middleware. Authorization checks run server-side in the Nitro engine, so you can gate API endpoints, server routes, and server-rendered pages before any response reaches the client.

### Can I use Cerbos in Nuxt middleware?

Yes. You can create a Nuxt server middleware that calls Cerbos on every request, or use route-specific middleware to authorize access to protected pages and API routes. The Cerbos PDP responds in sub-millisecond time, so middleware checks add negligible latency.

### Does Cerbos work with Nuxt's hybrid rendering modes?

Cerbos authorization runs server-side, so it works with SSR, ISR, and API routes. For statically generated pages, you can use Cerbos on the API endpoints that serve protected data, ensuring authorization is always enforced regardless of rendering strategy.
