The cssstyle npm package is designed to mimic the CSSStyleDeclaration interface provided by browsers, allowing for the manipulation of CSS properties of elements in a JavaScript environment outside of the browser, such as in server-side applications or testing environments. It provides a way to parse, manipulate, and stringify CSS properties programmatically.
Parsing CSS properties
This feature allows the parsing of CSS text into individual properties that can be accessed and manipulated through the CSSStyleDeclaration object.
{"var CSSStyleDeclaration = require('cssstyle');
var css = new CSSStyleDeclaration();
css.cssText = 'color: blue; background-color: white;';
console.log(css.color); // 'blue'"}
Manipulating CSS properties
This feature enables the setting and getting of individual CSS properties using methods like setProperty and getPropertyValue.
{"var CSSStyleDeclaration = require('cssstyle');
var css = new CSSStyleDeclaration();
css.setProperty('color', 'red');
console.log(css.cssText); // 'color: red;'"}
Stringifying CSS properties
This feature allows the CSSStyleDeclaration object to be converted back into a string representation of the CSS, which can be used in HTML or other contexts.
{"var CSSStyleDeclaration = require('cssstyle');
var css = new CSSStyleDeclaration();
css.setProperty('color', 'red');
console.log(css.cssText); // 'color: red;'"}
jsdom is a JavaScript implementation of many web standards, including the DOM and HTML standards. It provides a way to simulate a web page environment, including CSS parsing and manipulation, similar to cssstyle but with a broader scope including the full DOM API.
styled-components is a library for React and React Native that allows developers to write CSS in JavaScript, using tagged template literals. It offers a different approach to styling components compared to cssstyle, focusing on component-level styles in a React ecosystem.
JSS is an authoring tool for CSS which allows you to use JavaScript to describe styles in a declarative, conflict-free and reusable way. It is similar to cssstyle in that it allows manipulation of CSS in JavaScript, but it is more focused on generating CSS using JavaScript objects and functions.
