## Installation
```bash npm2yarn
npm i puppeteer # Downloads compatible Chrome during installation.
npm i puppeteer-core # Alternatively, install as a library, without downloading Chrome.
```
## Example
```ts
import puppeteer from 'puppeteer';
import puppeteer from 'puppeteer'; // or import puppeteer from 'puppeteer-core';
(async () => {
// Launch the browser and open a new blank page
const browser = await puppeteer.launch();
const page = await browser.newPage();
// Navigate the page to a URL
// Navigate the page to a URL.
await page.goto('https://developer.chrome.com/');
// Set screen size
// Set screen size.
await page.setViewport({width: 1080, height: 1024});
// Type into search box
// Type into search box.
await page.type('.devsite-search-field', 'automate beyond recorder');
// Wait and click on first result
// Wait and click on first result.
const searchResultSelector = '.devsite-result-item-link';
await page.waitForSelector(searchResultSelector);
await page.click(searchResultSelector);
// Locate the full title with a unique string
const textSelector = await page.waitForSelector(
'text/Customize and automate'
);
// Locate the full title with a unique string.
const textSelector = await page.waitForSelector('text/Customize and automate');
const fullTitle = await textSelector?.evaluate(el => el.textContent);
// Print the full title
// Print the full title.
console.log('The title of this blog post is "%s".', fullTitle);
await browser.close();
})();

## Remarks
The argument `options` might have the following properties:

## Installation
```bash npm2yarn
npm i puppeteer # Downloads compatible Chrome during installation.
npm i puppeteer-core # Alternatively, install as a library, without downloading Chrome.
```
## Example
```ts
import puppeteer from 'puppeteer';
import puppeteer from 'puppeteer'; // or import puppeteer from 'puppeteer-core';
(async () => {
// Launch the browser and open a new blank page
const browser = await puppeteer.launch();
const page = await browser.newPage();
// Navigate the page to a URL
// Navigate the page to a URL.
await page.goto('https://developer.chrome.com/');
// Set screen size

await page.setViewport({width: 1080, height: 1024});
// Type into search box
// Type into search box.
await page.type('.devsite-search-field', 'automate beyond recorder');
// Wait and click on first result
// Wait and click on first result.
const searchResultSelector = '.devsite-result-item-link';
await page.waitForSelector(searchResultSelector);
await page.click(searchResultSelector);
// Locate the full title with a unique string
const textSelector = await page.waitForSelector(
