Specify externals in nuxt module

Is it possible to add to the externals array passed to rollup to mark a dependency as external?

Hi @bnason. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, it is possible to specify external dependencies in a Nuxt module. This can be done by configuring the rollupOptions.external property in the Vite configuration of your Nuxt project. Here's how you can do it: 1. In your nuxt.config.ts file, you can add the following configuration:

export default defineNuxtConfig({
  vite: {
    build: {
      rollupOptions: {
        external: ['package-name-to-externalize']
      }
    }
  }
})

export default defineNuxtConfig({
  vite: {
    build: {
      rollupOptions: {
        external: ['package-name-to-externalize']
      }
    }
  }
})

Replace 'package-name-to-externalize' with the name of the package you want to mark as external. 2. Alternatively, if you're creating a Nuxt module, you can modify the Vite configuration within your module setup function:

export default defineNuxtModule({
  setup(options, nuxt) {
    nuxt.hook('vite:extendConfig', (config) => {
      config.build = config.build || {}
      config.build.rollupOptions = config.build.rollupOptions || {}
      config.build.rollupOptions.external = config.build.rollupOptions.external || []
      
      if (Array.isArray(config.build.rollupOptions.external)) {
        config.build.rollupOptions.external.push('package-name-to-externalize')
      }
    })
  }
})

export default defineNuxtModule({
  setup(options, nuxt) {
    nuxt.hook('vite:extendConfig', (config) => {
      config.build = config.build || {}
      config.build.rollupOptions = config.build.rollupOptions || {}
      config.build.rollupOptions.external = config.build.rollupOptions.external || []
      
      if (Array.isArray(config.build.rollupOptions.external)) {
        config.build.rollupOptions.external.push('package-name-to-externalize')
      }
    })
  }
})

This approach allows you to add to the external array without overwriting any existing configuration. It's worth noting that Nuxt 3 already externalizes vue, @vue/*, and vue-router by default, as mentioned in the Nuxt Configuration documentation. Remember that externalizing dependencies can affect how your application is built and bundled, so use this feature judiciously and test thoroughly to ensure it doesn't break your application's functionality. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai actually, I need to extend the external array that is used in the nuxt-build-module project that builds modules

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the misunderstanding. Based on your clarification, you're looking to extend the external array specifically for building Nuxt modules. Unfortunately, the knowledge sources provided don't contain specific information about extending the external array in the nuxt-build-module project. However, I can provide some general guidance based on the available information: 1. The external configuration is typically used to specify dependencies that should not be bundled with the module, but instead treated as external dependencies. 2. In Nuxt module development, the process of extending build configurations can sometimes differ from regular Nuxt application development. 3. The Nuxt documentation on authoring layers mentions that you can access nuxt.options._layers to support custom multi-layer handling for your modules. While this isn't directly related to the external array, it shows that there are ways to access and modify Nuxt's internal configurations when developing modules. To provide a more accurate and helpful answer specific to extending the external array in the nuxt-build-module project, we would need more detailed information or documentation about that particular project. If you have access to the nuxt-build-module documentation or source code, you might find more specific instructions there. If you can't find the information you need, you might want to consider reaching out to the maintainers of the nuxt-build-module project or checking their issue tracker for similar questions or feature requests. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
