# @push.rocks/smartpuppeteer
simplified access to puppeteer

## Install
To install `@push.rocks/smartpuppeteer` in your project, run the following command using npm:

```sh
npm install @push.rocks/smartpuppeteer --save
```

Or using yarn:

```sh
yarn add @push.rocks/smartpuppeteer
```

## Usage
`@push.rocks/smartpuppeteer` simplifies interaction with Puppeteer, providing easier ways to launch Puppeteer instances considering environment constraints, such as running in a CI pipeline or as root, which necessitates certain flags for Chrome.

Here, we give a comprehensive guide to using `@push.rocks/smartpuppeteer` in various scenarios, using ESM syntax and TypeScript.

### Basic Setup
Firstly, let’s set up the basic environment for using `@push.rocks/smartpuppeteer`:

```typescript
import { getEnvAwareBrowserInstance, IncognitoBrowser, puppeteer } from '@push.rocks/smartpuppeteer';

// Usually, you would initialize the browser instance at the start of your script or application logic
const initializeBrowser = async () => {
  const browser = await getEnvAwareBrowserInstance({
    forceNoSandbox: true, // A flag useful for certain environments; use it with caution
  });
  return browser;
};
```

### Opening a Page and Navigating
After obtaining a browser instance, you commonly want to open a page and navigate to a URL:

```typescript
const openPage = async (browser: puppeteer.Browser) => {
  const page = await browser.newPage();
  await page.goto('https://www.example.com');
  const pageTitle = await page.title();
  console.log(`Page title: ${pageTitle}`);
  // Always close the browser after you are done to free resources
  await browser.close();
};

// Utilize the async function
initializeBrowser()
  .then(openPage)
  .catch(console.error);
```

### Using Incognito Mode for Isolated Sessions
`@push.rocks/smartpuppeteer` offers easy management of incognito sessions, allowing isolated environments within the same browser instance:

```typescript
const useIncognitoBrowser = async () => {
  const incognitoBrowser = new IncognitoBrowser();
  await incognitoBrowser.start(); // Initializes a new incognito browser instance
  const context = await incognitoBrowser.getNewIncognitoContext();
  const page = await context.newPage();
  await page.goto('https://www.privacyfocusedsite.com');
  // Perform actions in the isolated session
  // Tidy up
  await incognitoBrowser.stop(); // Stops the incognito browser and closes all its pages and contexts
};

useIncognitoBrowser()
  .then(() => console.log('Incognito session used successfully'))
  .catch(console.error);
```

### Advanced Configuration
`@push.rocks/smartpuppeteer` allows further customization for launching the Puppeteer browser, such as disabling the sandbox environment (not recommended for production).

### Handling Browser Events
It's important to handle browser events, such as disconnections, which might occur due to various reasons:

```typescript
const browserWithEventHandling = async () => {
  const browser = await getEnvAwareBrowserInstance();
  browser.on('disconnected', () => {
    console.log('Browser disconnected. Handling reconnection...');
    // Implement reconnection logic here
  });
  // Utilize the browser for tasks
};

browserWithEventHandling()
  .then(() => console.log('Handled browser events successfully'))
  .catch(console.error);
```

### Rotation of Browsers and Pages
In scenarios such as web scraping or automated testing, you might want to rotate between browser instances or pages to manage memory usage or simulate new sessions:

```typescript
const rotateBrowserInstances = async (incognitoBrowser: IncognitoBrowser) => {
  // Assuming incognitoBrowser is already initialized and started
  await incognitoBrowser.rotateBrowser(); // Closes the current browser and starts a new instance
  // Now you have a fresh browser instance
};

// Example usage
const incognitoBrowser = new IncognitoBrowser();
incognitoBrowser.start()
  .then(() => rotateBrowserInstances(incognitoBrowser))
  .catch(console.error);
```

`@push.rocks/smartpuppeteer` with its encapsulated features and simplified API provides an efficient way to harness the power of Puppeteer without getting bogged down by its complexities. Whether you are handling web scraping, automated testing, or any task requiring browser automation, `@push.rocks/smartpuppeteer` streamlines the process, making it more accessible and manageable even for those new to Puppeteer.
