krawler - A web crawling framework written in Kotlin
Krawler is a web crawling framework written in Kotlin. It is heavily inspired by crawler4j by Yasser Ganjisaffar. The project is still very new, and those looking for a mature, well tested crawler framework should likely still use crawler4j. For those who can tolerate a bit of turbulence, Krawler should serve as a replacement for crawler4j with minimal modifications to existing applications. Using the Krawler framework is fairly simple. Minimally, there are two methods that must be overridden in order to use the framework. Overriding the shouldVisit method dictates what should be visited by the crawler, and the visit method dictates what happens once the page is visited. Overriding these two methods is sufficient for creating your own crawler, however there are additional methods that can be overridden to privde more robust behavior.
