🚜 A Simple Web Scraper in Go
If you need the whole code you can get it at the bottom of the post. In this example I use BeautifulSoup and Requests as third party libraries and urllibcollections and re as built-in libraries. BeautifulSoup provides a simple way for searching an HTML document, and the Request library allows you to easily perform web requests.
The following piece of code defines a list of urls to start the crawling from. You can add any number of urls that you want to start the scraping from. Next, we need to store the processed urls somewhere so as not to process them twice. As soon as we take a url out of the queue, we will add it to the list of processed urls, so that we do not forget about it in the future:.
When we have gotten the page, we can search for all new emails on it and add them to our set. For email extraction I use a simple regular expression for matching email addresses :. If the link address starts with a hash, then we count it as a relative link, and it is necessary to add the base url to the beginning of it:.

The http package provides a http. Get url method that only requires a few lines of code. Here are the possible things that a token can represent documentation :.
Now that we have found the anchor tags, how do we get the href value? The trickiest part of this scraper is how it uses channels. In order for the scraper to run quickly, it needs to fetch all URLs concurrently. When concurrency is applied, total execution time should equal the time taken to fetch the slowest request.
Without concurrency, execution time would equal the sum of all request times since it would be executing them one after the other. So how do we do this? The approach I took is to create a goroutine for each request and have each one publish the URLs it finds to a shared channel.
How do we know when the last URL is sent to the channel so we can close it? For this, we can use a second channel for communicating status.
The second channel is simply a notification channel. Then, main thread can subscribe to the notification channel and stop execution after all goroutines have notified that they are finished.
