Overview of this book

Web scraping is the process of extracting information from the web using various tools that perform scraping and crawling. Go is emerging as the language of choice for scraping using a variety of libraries. This book will quickly explain to you, how to scrape data data from various websites using Go libraries such as Colly and Goquery. The book starts with an introduction to the use cases of building a web scraper and the main features of the Go programming language, along with setting up a Go environment. It then moves on to HTTP requests and responses and talks about how Go handles them. You will also learn about a number of basic web scraping etiquettes. You will be taught how to navigate through a website, using a breadth-first and then a depth-first search, as well as find and follow links. You will get to know about the ways to track history in order to avoid loops and to protect your web scraper using proxies. Finally the book will cover the Go concurrency model, and how to run scrapers in parallel, along with large-scale distributed web scraping.

This form data could entail search queries, or a login screen, or any page that would require you to type into a box and click a Submit button.

For simple websites, this is done using an HTML <form> element, containing one or more <input> elements and a Submit button. This <form> element usually has attributes defining the action (where to send the <form> data), and a method (the HTTP method to use). By default, the web page will use an HTTP GET request to send the form data,...
