Object Type#

When tools.autoprefixer is configured as Object type, it is merged with the default config through Object.assign. For example:

export default {
  tools: {
    autoprefixer: {
      flexbox: 'no-2009',
    },
  },
};

Function Type#

When tools.autoprefixer is a Function, the default config is passed as the first parameter and can be directly modified or returned as the final result. For example:

export default {
  tools: {
    autoprefixer(config) {
      // modify flexbox config
      config.flexbox = 'no-2009';
    },
  },
};
