Whether to disable Source Map generation.

By default, Builder's Source Map generation rules are:

• In development build, SourceMap of JS files and CSS files will be generated, which is convenient for debugging.
• In production build, the Source Map of JS files will be generated for debugging and troubleshooting online problems; the Source Map of CSS files will not be generated.

If the project does not need Source Map, you can turned off it to speed up the compile speed.

export default {
  output: {
    disableSourceMap: true,
  },
};

If you want to enable Source Map in development and disable it in the production, you can set to:

export default {
  output: {
    disableSourceMap: process.env.NODE_ENV === 'production',
  },
};

If you need to individually control the Source Map of JS files or CSS files, you can refer to the following settings:

export default {
  output: {
    disableSourceMap: {
      js: false,
      css: true,
    },
  },
};
