splashr : Tools to Work with the ‘Splash’ JavaScript Rendering Service
TL;DR: This package works with Splash rendering servers which are really
just a REST API & lua scripting interface to a QT browser. It’s an
alternative to the Selenium ecosystem which was really engineered for
application testing & validation.
Sometimes, all you need is a page scrape after javascript has been
allowed to roam wild and free over meticulously crafted HTML tags. So,
this package does not do everything Selenium can in pure R (though,
the Lua interface is equally as powerful and accessible via R), but if
you’re just trying to get a page back that needs javascript rendering,
this is a nice, lightweight, consistent alternative.
It’s also an alternative to the somewhat abandoned phantomjs (which
you can use in R within or without a Selenium context as it’s it’s own
webdriver) and it may be useful to compare renderings between this
package & phantomjs.
The package uses the
stevedore package to
orchestrate Docker on your system (if you have Docker and more on how to
use the stevedore integration below) but you can also do get it
running in Docker on the command-line with two commands:
sudo docker pull scrapinghub/splash:latest --disable-browser-caches
sudo docker run -p 5023:5023 -p 8050:8050 -p 8051:8051 scrapinghub/splash:latest --disable-browser-caches
Do whatever you Windows ppl do with Docker on your systems to make ^^
work.
Folks super-new to Docker on Unix-ish platforms should make sure to
do:
sudo groupadd docker
sudo usermod -aG docker $USER
($USER is your username and shld be defined for you in the
environment)
If using the stevedore
package you can use the convience wrappers in this pacakge:
install_splash()
splash_container <- start_splash()
and then run:
stop_splash(splash_container)
when done. All of that happens on your localhost and you will not need
to specify splash_obj to many of the splashr functions if you’re
running Splash in this default configuration as long as you use named
parameters. You can also use the pre-defined splash_local object if
you want to use positional parameters.
Now, you can run Selenium in Docker, so this is not unique to Splash.
But, a Docker context makes it so that you don’t have to run or maintain
icky Python stuff directly on your system. Leave it in the abandoned
warehouse district where it belongs.
All you need for this package to work is a running Splash instance. You
provide the host/port for it and it’s scrape-tastic fun from there!
About Splash
‘Splash’ https://github.com/scrapinghub/splash is a javascript
rendering service. It’s a lightweight web browser with an ‘HTTP’ API,
implemented in Python using ‘Twisted’and ’QT’ [and provides some of
the core functionality of the ‘RSelenium’ or ‘seleniumPipes’ R
packages but with a Java-free footprint]. The (twisted) ‘QT’ reactor
is used to make the sever fully asynchronous allowing to take
advantage of ‘webkit’ concurrency via QT main loop. Some of Splash
features include the ability to process multiple webpages in parallel;
retrieving HTML results and/or take screenshots; disabling images or
use Adblock Plus rules to make rendering faster; executing custom
JavaScript in page context; getting detailed rendering info in HAR
format.
The following functions are implemented:
render_html: Return the HTML of the javascript-rendered page.render_har: Return information about Splash interaction with a
website in HAR
format.render_jpeg: Return a image (in JPEG format) of the
javascript-rendered page.render_png: Return a image (in PNG format) of the
javascript-rendered page.execute_lua: Execute a custom rendering script and return a
result.splash: Configure parameters for connecting to a Splash serverinstall_splash: Retrieve the Docker image for Splashstart_splash: Start a Splash server Docker containerstop_splash: Stop a running a Splash server Docker container
Mini-DSL (domain-specific language). These can be used to create a
“script” without actually scripting in Lua. They are a
less-powerful/configurable set of calls than what you can make with a
full Lua function but the idea is to have it take care of very common
but simple use-cases, like waiting a period of time before capturing a
HAR/HTML/PNG image of a site:
splash_plugins: Enable or disable browser plugins (e.g. Flash).splash_click: Trigger mouse click event in web page.splash_focus: Focus on a document element provided by a CSS
selectorsplash_images: Enable/disable imagessplash_response_body: Enable or disable response content tracking.splash_go: Go to an URL.splash_wait: Wait for a period timesplash_har: Return information about Splash interaction with a
website in HAR format.splash_html: Return a HTML snapshot of a current page.splash_png: Return a screenshot of a current page in PNG format.splash_press: Trigger mouse press event in web page.splash_release: Trigger mouse release event in web page.splash_send_keys: Send keyboard events to page context.splash_send_text: Send text as input to page context, literally,
character by character.splash_user_agent: Overwrite the User-Agent header for all further
requests. NOTE: There are many “helper” user agent strings to go
with splash_user_agent. Look for objects in splashr starting
with ua_.
httr helpers. These help turn various bits of splashr objects into
httr-ish things:
as_req: Turn a HAR response entry into a working httr function
you can use to make a request withas_request: Turn a HAR response entry into an httr
response-like object (i.e. you can use httr::content() on it)
Helpers:
tidy_har: Turn a gnHARly HAR object into a tidy data frameget_body_size: Retrieve size of content | body | headersget_content_sie: Retrieve size of content | body | headersget_content_type Retrieve or test content type of a HAR request
objectget_headers_size Retrieve size of content | body | headersis_binary: Retrieve or test content type of a HAR request objectis_content_type: Retrieve or test content type of a HAR request
objectis_css: Retrieve or test content type of a HAR request objectis_gif: Retrieve or test content type of a HAR request objectis_html: Retrieve or test content type of a HAR request objectis_javascript: Retrieve or test content type of a HAR request
objectis_jpeg: Retrieve or test content type of a HAR request objectis_json: Retrieve or test content type of a HAR request objectis_plain: Retrieve or test content type of a HAR request objectis_png: Retrieve or test content type of a HAR request objectis_svg: Retrieve or test content type of a HAR request objectis_xhr: Retrieve or test content type of a HAR request objectis_xml: Retrieve or test content type of a HAR request object
Some functions from HARtools are imported/exported and %>% is
imported/exported.
TODO
Suggest more in a feature req!
- Implement
render.json
- Implement “file rendering”
- Implement
execute (you can script Splash!)
- Add integration with
HARtools
- Possibly writing R function wrappers to install/start/stop
Splash which would also support enabling javascript
profiles, request filters and proxy profiles from with R directly,
using
harbor
- Re-implement
render_file()
- Testing results with all combinations of parameters
