Gerapy is a Distributed Crawler Management Framework Based on Scrapy, Scrapyd, Scrapyd-Client, Scrapyd-API, Django and Vue.js.

It is built on top of the Scrapy framework and provides a simple and easy-to-use interface for performing web scraping tasks. Gerapy also includes features such as support for scheduling and distributed crawling, as well as a built-in web-based dashboard for monitoring and managing scraping tasks. Additionally, Gerapy is designed to be highly extensible, allowing users to easily create custom plugins and integrations.

Overall, Gerapy is a useful tool for those looking to automate web scraping tasks and extract data from websites.

Gocrawl is a polite, slim and concurrent web crawler library written in Go. It is designed to be simple and easy to use, while still providing a high degree of flexibility and control over the crawling process.

One of the key features of Gocrawl is its politeness, which means that it obeys the website's robots.txt file and respects the crawl-delay specified in the file. It also takes into account the website's last modified date, if any, to avoid recrawling the same page. This helps to reduce the load on the website and prevent any potential legal issues. Gocrawl is also highly concurrent, which allows it to efficiently crawl large numbers of pages in parallel. This helps to speed up the crawling process and reduce the time required to complete the task.

The library also offers a high degree of flexibility in customizing the crawling process. It allows you to specify custom callbacks and handlers for handling different types of pages, such as error pages, redirects, and so on. This allows you to handle and process the pages as per your requirement. Additionally, Gocrawl provides various functionalities such as support for cookies, user-agent, auto-detection of links, and auto-detection of sitemaps.

Example Use

```go // Only enqueue the root and paths beginning with an "a" var rxOk = regexp.MustCompile(`http://duckduckgo\.com(/a.*)?$`) // Create the Extender implementation, based on the gocrawl-provided DefaultExtender, // because we don't want/need to override all methods. type ExampleExtender struct { gocrawl.DefaultExtender // Will use the default implementation of all but Visit and Filter } // Override Visit for our need. func (x *ExampleExtender) Visit(ctx *gocrawl.URLContext, res *http.Response, doc *goquery.Document) (interface{}, bool) { // Use the goquery document or res.Body to manipulate the data // ... // Return nil and true - let gocrawl find the links return nil, true } // Override Filter for our need. func (x *ExampleExtender) Filter(ctx *gocrawl.URLContext, isVisited bool) bool { return !isVisited && rxOk.MatchString(ctx.NormalizedURL().String()) } func ExampleCrawl() { // Set custom options opts := gocrawl.NewOptions(new(ExampleExtender)) // should always set your robot name so that it looks for the most // specific rules possible in robots.txt. opts.RobotUserAgent = "Example" // and reflect that in the user-agent string used to make requests, // ideally with a link so site owners can contact you if there's an issue opts.UserAgent = "Mozilla/5.0 (compatible; Example/1.0; +http://example.com)" opts.CrawlDelay = 1 * time.Second opts.LogFlags = gocrawl.LogAll // Play nice with ddgo when running the test! opts.MaxVisits = 2 // Create crawler and start at root of duckduckgo c := gocrawl.NewCrawlerWithOptions(opts) c.Run("https://duckduckgo.com/") // Remove "x" before Output: to activate the example (will run on go test) // xOutput: voluntarily fail to see log output } ```
