In some common situations which there are a large number of concurrent jobs, simply wrapping ".get" inside a Future seems problematic as the Future would take a spot in execution context's thread-pool. Is there any plan for building an async version? If not, I can get started and make a pull request.

I'm planning on working this weekend on extending the Browser
interface to support async browser implementations and providing a naive factory method that wraps a non-async Browser
by wrapping calls in futures. Once I do that, a pull request with a proper async implementation would be very helpful :)

Hi @frankandrobot! It's a good point and the Browser
implementations are probably not thread-safe. I'll get to improve both the browser implementations and the API later.
Nevertheless, you can easily load several pages in parallel by just wrapping the operations in a Future
, like:
import scala.concurrent.ExecutionContext.global
import scala.concurrent.Future
val doc: Future[Document] = Future { JsoupBrowser().get("http://example.com") }
You can implement your custom loader that returns a Document
, you really just need to implement its interface (location
, root
and toHtml
methods). You will probably have less work if you use jsoup
or HtmlUnit
for parsing the HTML though, as scala-scraper
already provides Document
instances wrapping the models for these libraries.
