Usage

Learn how to use headers and middleware both globally and per route.


Nuxt Security by default registers a set of global Nuxt routeRules that will make your application more secure by default. Both headers and middleware can be easily configured and even disabled when needed.

Global configuration

To override default behavior for Nuxt Security globally, follow this pattern:

export default defineNuxtConfig({  security: {    headers: {      // certain header      xXSSProtection: '1',    },    // certain middleware    rateLimiter: {      // options    }  }})

Per route configuration

To enable per-route configuration, use the routeRules like following:

export default defineNuxtConfig({  routeRules: {    '/custom-route': {      headers: {        'Foo': 'Bar'        /* DO NOT DEFINE SECURITY HEADERS HERE        'Cross-Origin-Embedder-Policy': 'require-corp'        */      }      security: {        // INSTEAD USE THE CUSTOM NUXT-SECURITY PROPERTY        headers: {          // certain header          crossOriginEmbedderPolicy: 'require-corp'        },        // certain middleware        rateLimiter: {          // options        }      }    }  }})
When using routeRules, do not use the standard headers property to define Nuxt Security options.
Instead, make sure to use the security property. This is a custom NuxtSecurity addition that does not exists in core Nuxt.
If your application defines conflicting headers at both levels, the security property will take precedence.

For more information on routeRules please see the Nuxt documentation

Nested route configuration

Nuxt Security will recursively resolve nested routes using your routeRules definitions:

export default defineNuxtConfig({  // Global  security: {    headers: {      crossOriginEmbedderPolicy: 'require-corp' // By default, COEP is 'require-corp'    }  }  // Per route  routeRules: {    '/some-prefix/**': {      security: {        headers: {          crossOriginEmbedderPolicy: false // COEP disabled on all routes beginning with /some-prefix/        }      }    },    '/some-prefix/some-route': {      security: {        headers: {          crossOriginEmbedderPolicy: 'credentialless' // COEP is 'credentialless' on /some-prefix/some-route        }      }    }  }})

Inline route configuration

You can also use route roules in pages like following:

<template>  <div>Hello from page</div></template><script setup lang="ts">defineRouteRules({  security: {    headers: {      xXSSProtection: '1'    },    rateLimiter: {      tokensPerInterval: 3,      interval: 60000,    },  }})</script>
To enable this macro, add the following configuration to your nuxt.config.ts file:
experimental: {  inlineRouteRules: true},

Disabling functionality

To disable certain middleware or headers, follow this pattern:

export default defineNuxtConfig({  // global  security: {    headers: {      // certain header      contentSecurityPolicy: false    },    // certain middleware    rateLimiter: false  },  // per route  routeRules: {    '/custom-route': {      security: {        rateLimiter: false      }    }  }})
