Explained by an example:
import fs from "fs"
import cheerio from "cheerio"
import { render } from "cheerio-to-text"
const html = fs.readFileSync("page.html", "utf-8")
console.log(html)
//
// <!doctype html>
// <body>
// <div id="main">
// <p>Para<strong>graph</strong>.</p>
// <ul><li>Foo</li><li>Bar</li></ul><h3>Heading</h3>
// </div>
// </body>
//
const $ = cheerio.load(html)
console.log($("div#main").text())
//
// Paragraph.
// FooBarHeading
//
console.log(render($("div#main")))
//
// Paragraph.
// Foo
// Bar
// Heading
//Much of the origin of this that GitHub Docs scrapes
every page with got and cheerio and then needs to convert that into an
appropriate string of plain text that it can use for searching
with Elasticsearch. Using myCheerioObject.text() isn't good enough
because it lumps together HTML blocking tags that have no whitespace
between the > and the next <.

Run npm run build:watch in one terminal the look at
example.mjs (which you run with node example.mjs)
