Browser management

Usually, you start working with Puppeteer by launching a browser instance. This browser instance is controlled by Puppeteer and can be used to open new tabs, navigate to different URLs, interact with web pages, and perform various tasks.

Launching a Browser

import puppeteer from "puppeteer";

const browser = await puppeteer.launch();

const page = await browser.newPage();

When launching a browser, you can specify various options to customize its behavior. These options include:

• headless: A boolean value that determines whether the browser should run in headless mode (without a visible UI). By default, this option is set to true.
• slowMo: A number that introduces a delay (in milliseconds) between Puppeteer actions. This can be useful for debugging or observing the automation process.
• defaultViewport: An object that defines the initial browser window size and scale factor. This can be useful for ensuring consistent rendering across different devices.
• args: An array of strings that specify additional command-line arguments to pass to the browser instance. These arguments can modify the browser's behavior or enable specific features.
• and more...

const browser = await puppeteer.launch({
  headless: false,
  slowMo: 250,
  defaultViewport: null,
  args: ["--start-maximized"],
});

Closing the Browser

Once you're done working with the browser, you should close it to free up system resources. You can close the browser instance using the browser.close() method.

import puppeteer from "puppeteer";

const browser = await puppeteer.launch();

const page = await browser.newPage();

await browser.close();
