# Automation Basics

Welcome to Monitoro Herd! This guide will walk you through creating your first browser automation step-by-step. We'll start with the basics and gradually build up to more complex examples, explaining each concept along the way.

## javascript

## JavaScript SDK

### Setting Up Your Environment

Before writing any code, you'll need to set up your JavaScript environment and install the Herd SDK:

1. Make sure you have Node.js installed (version 14 or higher recommended)
2. Create a new project directory
3. Install the SDK using npm:

Code (bash):
npm install @monitoro/herd

### Initializing the Client

The first step in any automation is to initialize the Herd client with your API credentials:

Code (javascript):
// Import the Herd client
import { HerdClient } from '@monitoro/herd';

// Initialize the client with your API URL and token
const client = new HerdClient('your-token');

// Always initialize the client before using it
await client.initialize();
Note: **Note:** Replace the token with your actual Herd API token from your dashboard.

### Connecting to a Device

After initializing the client, you need to connect to a device (browser) that will perform the automation:

Code (javascript):
// Get a list of available devices
const devices = await client.listDevices();

// Connect to the first available device
const device = devices[0];

console.log(`Connected to device: ${device.id}`);

This code retrieves all devices registered to your account and connects to the first one. In a production environment, you might want to select a specific device based on its properties or availability.

### Creating a Page and Navigating

Now that you're connected to a device, you can create a new browser page and navigate to a website:

Code (javascript):
// Create a new page in the browser
const page = await device.newPage();

// Navigate to a website
await page.goto('https://example.com');

console.log('Successfully navigated to example.com');

The `goto` method loads the specified URL and waits for the page to load. By default, it waits until the page's `load` event is fired, but you can customize this behavior with options.

### Extracting Basic Information

One of the most common automation tasks is extracting information from web pages. Here's how to extract basic elements:

Code (javascript):
// Extract content using CSS selectors
const content = await page.extract({
  title: 'h1',           // Extracts the main heading
  description: 'p',      // Extracts the first paragraph
  link: 'a'              // Extracts the first link text
});

// Display the extracted content
console.log('Extracted content:');
console.log(`Title: ${content.title}`);
console.log(`Description: ${content.description}`);
console.log(`Link: ${content.link}`);

The `extract` method uses CSS selectors to find elements on the page and extract their text content. This is a powerful way to scrape structured data from websites.

### Proper Resource Management

Always remember to close resources when you're done with them to prevent memory leaks:

Code (javascript):
// Close the page when done
