Bare minimum script for scraping a website with Node.js

scrape-public-website-html.js

const fetch = require("node-fetch")
const { JSDOM } = require("jsdom")

const fetchHtml = async (url) => {
  const response = await fetch(url)
  const text     = await response.text()
  const dom      = new JSDOM(text)
  return dom.window.document
}

const extractElements = (document, selector) => {
  const elements = Array.from(document.querySelectorAll(selector))
  return elements.map((element) => element.textContent)
}

const scrape = async (url, selector) => {
  const document = await fetchHtml(url)
  return extractElements(document, selector)
}

scrape("https://evanwinter.dev", ".nav li").then((data) => console.log(data))
