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.

What is Go?

Go is a programming language created by Google employees in 2007. At the time of its creation, the goal was to build a language that was fast, safe, and simple. Go first officially released its 1.0 version in 2012 and is one of the fastest growing programming languages today. According to the Stack Overflow 2018 Developer Survey, Go is ranked in the top five of the most-loved languages and the top three in the most-wanted languages.

Go powers many large-scale web infrastructure platforms and tools such as Docker, Kubernetes, and Terraform. These platforms enable companies to build production-scale products supporting Fortune 500 companies. This is mostly the result of the design of the Go language, making it straightforward and clear to work with. Many other companies using Go for their development often tout the performance improvements over other languages.
