    cssnano-preset-default

    Safe defaults for cssnano which require minimal configuration.

    Table of Contents

    Overview

    This default preset for cssnano only includes transforms that make no assumptions about your CSS other than what is passed in. In previous iterations of cssnano, assumptions were made about your CSS which caused output to look different in certain use cases, but not others. These transforms have been moved from the defaults to other presets, to make this preset require only minimal configuration.

    Usage

    Install

    Note that this preset comes bundled with cssnano by default, so you don't need to install it separately.

    Configuration

    If you would like to use the default configuration, then you don't need to add anything to your package.json.

    But should you wish to customise this, you can pass an array with the second parameter as the options object to use. For example, to remove all comments:

     {
       "name": "awesome-application",
    +  "cssnano": {
    +    "preset": [
    +      "default",
    +      {"discardComments": {"removeAll": true}}
    +    ]
    +  }
     }

    Depending on your usage, the JSON configuration might not work for you, such as in cases where you would like to use options with customisable function parameters. For this use case, we recommend a cssnano.config.js at the same location as your package.json. You can then load a preset and export it with your custom parameters:

    const defaultPreset = require('cssnano-preset-default');
    
    module.exports = defaultPreset({
      discardComments: {
        remove: (comment) => comment[0] === '@',
      },
    });

    Note that you may wish to publish your own preset to npm for reusability, should it differ a lot from this one. This is highly encouraged!
