#tools.terser

• Type: Object | Function | undefined
• Default:

const defaultTerserOptions = {
  terserOptions: {
    mangle: {
      safari10: true,
    },
  },
};

When building for production, Modern.js will minimize the JavaScript code through terser-webpack-plugin. The config of terser-webpack-plugin can be modified via tools.terser.

#Object Type

When tools.terser is Object type, it will be merged with the default config via Object.assign.

For example, to exclude some files from minification:

export default {
  tools: {
    terser: {
      exclude: /\/excludes/,
    },
  },
};

#Function Type

When tools.terser is Function type, the default config is passed in as the first parameter, the config object can be modified directly, or a value can be returned as the final result.

export default {
  tools: {
    terser: opts => {
      opts.exclude = /\/excludes/;
    },
  },
};
