Package description
The nwmatcher npm package is a fast CSS selector engine and matcher, primarily used for matching DOM elements against CSS selectors. It is useful for tasks such as querying and filtering elements in a DOM-like structure.
Matching Elements
This feature allows you to check if a given DOM element matches a specific CSS selector.
const NWMatcher = require('nwmatcher');
const matcher = NWMatcher({ document });
const element = document.getElementById('example');
const isMatch = matcher.match(element, '.example-class');
console.log(isMatch); // true or falseQuerying Elements
This feature allows you to query and retrieve all DOM elements that match a specific CSS selector.
const NWMatcher = require('nwmatcher');
const matcher = NWMatcher({ document });
const elements = matcher.select('.example-class');
console.log(elements); // Array of elements matching the selectorCustom Selectors
This feature allows you to register and use custom selectors for more advanced querying.
const NWMatcher = require('nwmatcher');
const matcher = NWMatcher({ document });
matcher.registerSelector('custom', function(element) {
return element.hasAttribute('data-custom');
});
const elements = matcher.select(':custom');
console.log(elements); // Array of elements with the 'data-custom' attributeSizzle is a pure-JavaScript CSS selector engine designed to be easily dropped in to a host library. It is highly optimized for performance and is used internally by jQuery. Compared to nwmatcher, Sizzle is more widely used and integrated into larger libraries like jQuery.
css-select is a library for selecting elements in a DOM-like structure using CSS selectors. It is part of the Cheerio library, which is used for server-side DOM manipulation. css-select is similar to nwmatcher but is often used in conjunction with Cheerio for server-side applications.
query-selector-shadow-dom is a library that extends the native querySelector and querySelectorAll methods to work with shadow DOM. It is useful for querying elements within shadow DOM trees, which nwmatcher does not natively support.
