parse-css-sides

This package exports a default function that parses CSS sides (e.g., the value of margin, padding and border declarations).

Originally created for PostCSS plugins.

Installation

$ npm install parse-css-sides [--save[-dev]]

Usage

JavaScript

import parseSides from 'parse-css-sides';
const sides = parseSides('0 5% 10px');
/**
 * {
 *   top: '0',
 *   right: '5%',
 *   bottom: '10px',
 *   left: '5%',
 * }
 **/

All 4 sides are always returned and are always strings.

Note: if !important is found, an additional important: true will be added to the result.

TypeScript

This is a TypeScript project with generated type definitions included. There is an additional ISides interface that is exported if you need it for whatever reason. It just defines the shape of the result:

interface ISides {
    top: string
    right: string
    bottom: string
    left: string
    important?: boolean
}

Testing
