📸 Screenshotting cljdoc

Trying out Sparkledriver to take screenshots with the built-in webkit browser that's bundled with the JDK.

1.
Sparkledriver

We start by requring sparkledriver.

(require '[sparkledriver.browser :refer [with-browser make-browser fetch!]])
(require '[sparkledriver.element :refer [screenshot]])
(require '[clojure.java.io :as io])
0.5s

Let's create a browser and a helper function.

(def browser
  (make-browser))

(defn preview [url]
  (-> (fetch! browser url)
    screenshot
    io/file
    (io/copy (io/file "/results/screenshot.png"))))
0.9s

And, let's shoot! 📸
