Disable Extract CSS

How can I disable extract css?

Hi @Yuri. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To disable CSS extraction in Nuxt, you need to set the extractCSS option to false in your Nuxt configuration. This option is available under the webpack section of your nuxt.config file:

export default {
  webpack: {
    extractCSS: false
  }
}

export default {
  webpack: {
    extractCSS: false
  }
}

By setting extractCSS to false, Nuxt will not extract CSS into separate files, and styles will be inlined instead. This is useful if you want to avoid separate CSS files and keep styles within your JavaScript bundles. For more details, see the official documentation on the extractCSS option here. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Will this work if I include CSS in the layout:

import "~/assets/css/mobile.css";

import "~/assets/css/mobile.css";

Let me check the knowledge base for you again. One moment! :books: ---------------------- If you import a CSS file directly in your layout using:

import "~/assets/css/mobile.css";

import "~/assets/css/mobile.css";

Nuxt will include the styles from that file in your application. According to the documentation, when you import stylesheets in your pages, layouts, or components using a JavaScript import, the stylesheets will be inlined in the HTML rendered by Nuxt. This behavior is independent of the extractCSS setting, as extractCSS specifically controls whether CSS is extracted into separate files during the build process when using webpack. If extractCSS is disabled, the styles will remain inlined within your JavaScript bundles rather than being output as separate CSS files Styling in Nuxt. So yes, importing CSS in your layout as shown will work, and the styles will be applied, but with extractCSS disabled, they will be inlined rather than extracted to a separate CSS file. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

But in my case CSS include as separated file in the prodaction mode. Why? @kapa.ai But in my case CSS include as separated file in the prodaction mode. Why?

Let me check the knowledge base for you again. One moment! :books: ---------------------- If your CSS is still being included as a separate file in production mode, even after disabling extractCSS, it may be because: 1. Nuxt 3 uses Vite by default, not Webpack:
The extractCSS option is specific to Webpack builds. In Nuxt 3, Vite is the default builder, and the extractCSS option does not apply. Vite handles CSS differently and will extract CSS into separate files for production by default. There is no documented way in the official Nuxt 3 docs to disable this behavior for Vite builds Styling in Nuxt. 2. Direct imports in layouts/components:
Importing CSS directly in your layout or component (e.g., import "~/assets/css/mobile.css";) will still result in those styles being bundled and, in production, extracted by Vite into a separate CSS file for optimal performance Styling in Nuxt. 3. No extractCSS equivalent for Vite:
The knowledge sources do not mention an option to inline all CSS in production when using Vite. The extractCSS option and related settings are only for Webpack builds Nuxt Config: webpack. Summary:
In Nuxt 3 (with Vite), CSS is extracted into separate files in production by default, and there is no documented configuration to disable this. The extractCSS option only works with Webpack, not Vite. If you need to inline all CSS, the knowledge sources do not provide a solution for Vite-based builds. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Do any ways exist to load critical CSS inline ? @kapa.ai Do any ways exist to load critical CSS inline ?

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, Nuxt provides ways to inline CSS, including critical CSS, but the behavior depends on your configuration and the Nuxt version. By default, Nuxt 3 inlines styles for Vue components but not for global CSS. However, you can revert to the previous behavior (where all CSS, including global styles, is inlined) by setting the following in your nuxt.config.ts:

export default defineNuxtConfig({
  features: {
    inlineStyles: true
  }
})

export default defineNuxtConfig({
  features: {
    inlineStyles: true
  }
})

This will inline both global and component CSS, which can be used to ensure critical CSS is delivered inline with your HTML. This setting is documented as a way to control the inlining of styles and can be useful for optimizing the delivery of critical CSS More Granular Inline Styles. If you need even more advanced control (such as inlining only specific critical CSS), the knowledge sources do not provide a built-in or documented way to do this selectively. For more granular or automated critical CSS extraction and inlining, you may need to look for third-party solutions or custom build steps, but this is not covered in the official documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
