How to extend Webpack to load audio files?

Audio files should be processed by file-loader. This loader is already included in the default Webpack configuration, but it is not set up to handle audio files. You need to extend its default configuration in nuxt.config.js:

export default {
  build: {
    extend(config, ctx) {
      config.module.rules.push({
        test: /\.(ogg|mp3|wav|mpe?g)$/i,
        loader: 'file-loader',
        options: {
          name: '[path][name].[ext]'
        }
      })
    }
  }
}

You can now import audio files like this <audio :src="require('@/assets/water.mp3')" controls></audio>.

If you only want to write: <audio src="@/assets/water.mp3" controls></audio>, you need to tell vue-loader to automatically require your audio files when you reference them with the src attribute:

export default {
  build: {
    loaders: {
      vue: {
        transformAssetUrls: {
          audio: 'src'
        }
      }
    },
    extend(config, ctx) {
      config.module.rules.push({
        test: /\.(ogg|mp3|wav|mpe?g)$/i,
        loader: 'file-loader',
        options: {
          name: '[path][name].[ext]'
        }
      })
    }
  }
}
