The cheerio-select npm package is a library that allows users to use CSS selectors to select and manipulate HTML elements within a cheerio instance. It is designed to work with the cheerio library, which is a fast, flexible, and lean implementation of core jQuery designed specifically for the server.

What are cheerio-select's main functionalities?

Selecting elements

This feature allows you to select HTML elements using CSS selectors. In the code sample, we select elements with the class 'apple' and log their text content.

const cheerio = require('cheerio');
const select = require('cheerio-select');
const html = '<ul id="fruits"><li class="apple">Apple</li><li class="orange">Orange</li></ul>';
const $ = cheerio.load(html);
const elements = select('.apple', $);
console.log($(elements).text()); // 'Apple'

Filtering elements

This feature allows you to filter a set of elements down to those that match a CSS selector. In the code sample, we filter a list of 'li' elements to only those with the class 'apple'.

const cheerio = require('cheerio');
const select = require('cheerio-select');
const html = '<ul id="fruits"><li class="apple">Apple</li><li class="orange">Orange</li></ul>';
const $ = cheerio.load(html);
const fruits = $('li').toArray();
const apples = select.filter('.apple', fruits, $);
console.log($(apples).text()); // 'Apple'
