Features

✅ Discover broken links - 404s and internal redirects
🚩 Warnings for bad practice links - absolute instead of relative and wrong trailing slash
🕵️ Fail on build if broken links are found (optional)

Install

npm install --save-dev nuxt-link-checker

# Using yarn
yarn add --dev nuxt-link-checker

Setup

nuxt.config.ts

export default defineNuxtConfig({
  modules: [
    'nuxt-link-checker',
  ],
})

To have routes scanned for broken links automatically, they need to be pre-rendered by Nitro.

export default defineNuxtConfig({
  nitro: {
    prerender: {
      crawlLinks: true,
      routes: [
        '/',
        // any URLs that can't be discovered by crawler
        '/my-hidden-url'
      ]
    }
  }
})

Set host (optional)

You'll need to provide the host of your site so that the crawler can resolve absolute URLs that may be internal.

export default defineNuxtConfig({
  // Recommended 
  runtimeConfig: {
    public: {
      siteUrl: process.env.NUXT_PUBLIC_SITE_URL || 'https://example.com',
    }
  },
  // OR 
  linkChecker: {
    host: 'https://example.com',
  },
})

Exclude URLs from throwing errors

You can exclude URLs from throwing errors by adding them to the exclude array.

For example, if you have an /admin route that is a separate application, you can ignore all /admin links with:

export default defineNuxtConfig({
  linkChecker: {
    exclude: [
      '/admin/**'
    ],
  },
})

Disable errors on broken links

You can disable errors on broken links by setting failOn404 to false.

export default defineNuxtConfig({
  linkChecker: {
    failOn404: false,
  },
})

Module Config

`failOn404`

Type: boolean
Default: true

If set to true, the build will fail if any broken links are found.

`exclude`

Type: string[]
Default: []

An array of URLs to exclude from the check.

This can be useful if you have a route that is not pre-rendered, but you know it will be valid.

`host`

Type: string
Default: runtimeConfig.public.siteUrl || localhost
Required: false

The host of your site. This is required to validate absolute URLs which may be internal.

`trailingSlash`

Type: boolean
Default: false

Whether internal links should have a trailing slash or not.
