Perfectionist 轻量级 CSS 代码格式化插件

Question

Perfectionist 是一个轻量级的 CSS 代码格式化插件，这个插件不仅可以格式化 CSS 代码，也可以压缩 CSS 代码，支持同属性缩进、自定义缩进字符数等特点。

安装

你可以通过 npm 安装 Perfectionist，通过下面的示例代码：

npm install perfectionist --save

运行示例

说的再多都是白搭，看到示例效果才是真的，下面的是一个简单的示例，例如我们输入如下的 CSS 代码：

h1   {
         color   :  red }

输出的方式大概有三种

/*格式化输出*/
h1 {
    color: red;
}

/*紧凑输出*/
h1 { color: red; }

/*压缩输出*/
h1{color:red}

API

perfectionist.process(css, [options])

css

Type: string Required option.

Pass a CSS string to beautify it.

options

cascade

Type: boolean Default: true

Set this to false to disable visual cascading of vendor prefixed properties. Note that this transform only applies to the expanded format.

true

h1 {
    -webkit-border-radius: 12px;
            border-radius: 12px;
}

false

h1 {
    -webkit-border-radius: 12px;
    border-radius: 12px;
}

format

Type: string Default: expanded

Pass either expanded, compact or compressed. Note that the compressed format only facilitates simple whitespace compression around selectors & declarations. For more powerful compression, see cssnano.

indentSize

Type: number Default: 4

This number will be used as a basis for all indent levels, using the expanded format.

maxAtRuleLength

Type: boolean|number Default: 80

If set to a positive integer, set a maximum width for at-rule parameters; if they exceed this, they will be split up over multiple lines. If false, this behaviour will not be performed. Note that this transform only applies to the expanded format.

maxSelectorLength

Type: boolean|number Default: 80

If set to a positive integer, set a maximum width for a selector string; if it exceeds this, it will be split up over multiple lines. If false, this behaviour will not be performed. Note that this transform is excluded from the compressed format.

maxValueLength

Type: boolean|number Default: 80

If set to a positive integer, set a maximum width for a property value; if it exceeds this, it will be split up over multiple lines. If false, this behaviour will not be performed. Note that this transform only applies to the expanded format.

sourcemap

Type: boolean Default: false

Generate a sourcemap with the transformed CSS.

syntax

Type: string

Specify scss if you would like to also format SCSS-style single line comments. This loads the postcss-scss plugin.

postcss([ perfectionist(opts) ])

perfectionist can also be consumed as a PostCSS plugin. See the documentation for examples for your environment.

CLI

perfectionist also ships with a CLI app. To see the available options, just run:

$ perfectionist --help
