Successor of Undetected-Chromedriver. Providing a blazing fast framework for web automation, webscraping, bots and any other creative ideas which are normally hindered by annoying anti bot systems like Captcha / CloudFlare / Imperva / hCaptcha
Direct communication provides even better resistance against web applicatinon firewalls (WAF’s), while
performance gets a massive boost.
This module is, contrary to undetected-chromedriver, fully asynchronous.
What makes this package different from other known packages,
is the optimization to stay undetected for most anti-bot solutions.
Another focus point is usability and quick prototyping, so expect a lot to work -as is-
,
with most method parameters having best practice
defaults.
Using 1 or 2 lines, this is up and running, providing best practice config
by default. It cleans up created files (profile) afterwards.
known to work with
While usability and convenience is important. It’s also easy
to fully customizable everything using the entire array of
CDP domains, methods and events available.
No chromedriver binary or Selenium dependency
Up and running in 1 line of code*
uses fresh profile on each run, cleans up on exit
save and load cookies to file to not repeat tedious login steps
tab.find("sometext")
tab.find_all("sometext")
tab.select("a[class*=something]")
tab.select_all("a[href] > div > img")
smart and performant element lookup, by selector or text, including iframe content.
this could also be used as wait condition for a element to appear, since it will retry
for the duration of await tab.select('body')
could be used
as an indicator whether a page is loaded.
the find method searches by text, but will not naively return the first
matching element, but will match candidates by closest matching text length (shortest wins),
this makes lookups like tab.find(‘accept all’) return the actual cookie button instead of
a script in the headers
can connect to a running chrome debug session
descriptive __repr__ for elements, which represent the element as html
utility function to convert a running undetected_chromedriver.Chrome instance
to a nodriver.Browser instance and contintue from there
packed with helpers and utility methods for most used and important operations
tab.cf_verify()
finds the checkbox and click it successfully
this only works when NOT in expert mode.
currently built-in english only
requires opencv-python package to be installed
tab.bypass_insecure_connection_warning()
convenience method, for insecure page warning.
for example when a certificate is invalid.
tab.open_external_debugger()
lets you inspect the tab without breaking your connection
tab.get_local_storage()
get localstorage content
tab.set_local_storage(dict)
set localstorage content
tab.add_handler(someEvent, callback)
callback may accept a single argument (event), or 2 arguments (event, tab).
start(expert=True)
does some hacking for more experienced users. It disables
web security and origin-trials, as well as ensures
shadow-roots are always open. This makes you more detectable though!
you need chrome (or some chromium based browser) installed
preferably in the default location
on the machine where you use this package.
when running on a headless machine, like AWS or any other environment where
no display is present, it’s best to use some Xvfb tool, to emulate a screen.
alternatively this package can be used in headless mode.
pip install nodriver
pip install -U nodriver
The aim of this project (just like undetected-chromedriver, somewhere long ago)
is to keep it short and simple, so you can quickly open an editor or interactive session,
type or paste a few lines and off you go.
