node-crawler VS colly

web crawlers: these are applications that systematically map all of the links on websites, and create a searchable index. A popular JS tool here is node-crawler.

Before you write your own library for crawling, try some of the options out there. Many great Open Source libraries can achieve it: Scrapy, pyspider, node-crawler (Node.js), or Colly (Go). And many companies and services that provide you with scraping and crawling solutions.

We could write some snippet mixing all of these, but the best option in real life is to use a tool with it all like Scrapy, pyspider, node-crawler (Node.js), or Colly (Go). The idea being the snippets is to understand each problem on its own. But for large-scale, real-life projects, handling everything on our own would be too complicated.

SerpApi focuses on scraping search results. That's why we need extra help to scrape individual sites. We'll use GoColly package.

Interesting. Can you compare it to colly? [0]

Last time I looked it was the most popular choice for scraping in Go and I have some projects using it.

Is it similar? Does it have more/less features or is it more suited for a different use case? (Which one?)

Sounds cool, but how is this different from Colly: https://github.com/gocolly/colly?

Unless you're specifically trying to do it using net/http, I recommend using colly. I've used it in a few scrappers and I love it!

In this blog, we will be covering the basics of web scraping in Go using the Fiber and Colly frameworks. Colly is an open-source web scraping framework written in Go. It provides a simple and flexible API for performing web scraping tasks, making it a popular choice among Go developers. Colly uses Go's concurrency features to efficiently handle multiple requests and extract data from websites. It offers a wide range of customization options, including the ability to set request headers, handle cookies, follow redirects, and more

github.com/gocolly/colly - popular and widely-used library for web scraping in Go. It provides a higher-level API than net/http and makes it easier to extract information from websites. It also provides features such as concurrency, automatic request retries, and support for cookies and sessions.
