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', 'john.doe@example.com');
await page.click('#submit');
await page.waitForNavigation();
await browser.close();
})();
