Puppeteer is a Node.js library which provides a high-level API to control Chrome or Firefox over the DevTools ProtocolorWebDriver BiDi. Puppeteer runs in the headless (no visible UI) by default but can be configured to run in a visible ( "headful" ) browser.
npm i puppeteer#Downloads compatible Chrome during installation.
npm i puppeteer-core#Alternatively, install as a library, without downloading Chrome.
importpuppeteerfrom'puppeteer';
// Or import puppeteer from 'puppeteer-core';
// Launch the browser and open a new blank page
constbrowser=awaitpuppeteer.launch();
constpage=awaitbrowser.newPage();
// Navigate the page to a URL.
awaitpage.goto('https://developer.chrome.com/');
// Set screen size.
awaitpage.setViewport({width:1080,height:1024});
// Type into search box.
awaitpage.locator('.devsite-search-field').fill('automate beyond recorder');
// Wait and click on first result.
awaitpage.locator('.devsite-result-item-link').click();
// Locate the full title with a unique string.
consttextSelector=awaitpage
.locator('text/Customize and automate')
.waitHandle();
constfullTitle=awaittextSelector?.evaluate(el=>el.textContent);
// Print the full title.
console.log('The title of this blog post is "%s".',fullTitle);
awaitbrowser.close();
