Why?

For most websites, bundling your entire web application into a single file is generally NOT RECOMMENDED. However, in certain scenarios, this can be useful, such as:

• Integrating your web app within desktop or mobile WebView components
• Deploying your web app to environments with strict access requirements
• Embedding your web app in embedded devices

In these special cases, nuxt-single-html allows you to leverage the powerful development experience of Nuxt while easily bundling your web app into a single HTML file, even supporting page pre-rendering.

This module is specifically designed to work with Nuxt. If you are looking for a similar solution for other frameworks, consider using vite-plugin-singlefile.

Quickstart

Install the module to your Nuxt application with one command:

npx nuxi module add nuxt-single-html

Install manually

npm i -D nuxt-single-html

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['nuxt-single-html']
})

Generate single HTML

After installing, you can now build your Nuxt app into a single HTML now, no configuration required. Since nuxi build does not prerender HTML files by default, you need to use nuxi generate to generate the HTML files.

npx nuxi generate

The HTML file output path depends on your (nitro.output.publicDir) Nuxt configuration. By default, it will be placed in the .output/public directory.

Configuration

You can define these options in your nuxt.config.js file under the singleHtml key.

Example Configuration:

export default {
  modules: [
    'nuxt-single-html'
  ],
  singleHtml: {
    enabled: true,
    deleteInlinedFiles: true,
    output: '[name].html'
  }
}

Options:

• enabled (boolean)

  • Description: Enables or disables the single HTML mode when running the nuxt generate command.
  • Default: true

• deleteInlinedFiles (boolean)

  • Description: Specifies whether to delete inlined files after generating the single HTML file.
  • Default: true

• output (string)

  • Description: The output filename for the generated single HTML file. You can use [name] to refer to the original HTML file name.
  • Default: '[name].html'

FAQ

How are the assets built?

All assets (images, fonts, CSS, etc.) inside the assets/ directory will be inlined into the single HTML file. However, assets inside the public/ directory will not be inlined. For more details, please refer to the Nuxt Assets documentation.

Why are multiple HTML files generated?

If you’re using Nuxt Pages, multiple single HTML files may be generated for each route. Each HTML file contains the full source code for all route pages, meaning they can operate independently and still support SPA behavior. The only difference is that each HTML file is pre-rendered for its corresponding route.

Simply put, if you only need index.html as your entry point, you can deploy just the index.html and able to safely ignore the other HTML files. You can also check out config memory history mode to fit your needs.
