@types/puppeteer

What is @types/puppeteer?

@types/puppeteer provides TypeScript type definitions for the Puppeteer library, which is a Node library that provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome or Chromium.

What are @types/puppeteer's main functionalities?

Launching a Browser

This feature allows you to launch a new browser instance, open a new page, navigate to a URL, and then close the browser.

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await browser.close();
})();

Taking a Screenshot

This feature allows you to take a screenshot of a webpage. The screenshot is saved to a file specified by the 'path' option.

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({ path: 'example.png' });
  await browser.close();
})();

Generating a PDF

This feature allows you to generate a PDF of a webpage. The PDF is saved to a file specified by the 'path' option and can be formatted using various options.

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.pdf({ path: 'example.pdf', format: 'A4' });
  await browser.close();
})();

Scraping Content

This feature allows you to scrape content from a webpage. The example code navigates to a URL and logs the text content of the page.

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  const content = await page.evaluate(() => document.body.textContent);
  console.log(content);
  await browser.close();
})();

Automating Form Submission

This feature allows you to automate form submission. The example code navigates to a form page, fills out the form fields, submits the form, and waits for the navigation to complete.

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com/form');
  await page.type('#name', 'John Doe');
  await page.type('#email', '[e-mail]');
  await page.click('#submit');
  await page.waitForNavigation();
  await browser.close();
})();
