Properties
optionalbrowserPerProxy
If set to true
, the crawler respects the proxy url generated for the given request.
This aligns the browser-based crawlers with the HttpCrawler
.
Might cause performance issues, as Crawlee might launch too many browser instances.
browserPlugin
The BrowserPlugin
instance used to launch the browser.
optionalexperimentalContainersexperimental
Like useIncognitoPages
, but for persistent contexts, so cache is used for faster loading.
Works best with Firefox. Unstable on Chromium.
optionalid
To make identification of LaunchContext
easier, BrowserPool
assigns
the LaunchContext
an id
that's equal to the id
of the page that
triggered the browser launch. This is useful, because many pages share
a single launch context (single browser).
launchOptions
The actual options the browser was launched with, after changes. Those changes would be typically made in pre-launch hooks.
optionalproxyTier
optionalproxyUrl
optionaluseIncognitoPages
By default pages share the same browser context.
If set to true
each page uses its own context that is destroyed once the page is closed or crashes.
optionaluserDataDir
Path to a User Data Directory, which stores browser session data like cookies and local storage.
LaunchContext
holds information about the launched browser. It's useful to retrieve thelaunchOptions
, the proxy the browser was launched with or any other information user chose to add to theLaunchContext
by calling itsextend
function. This is very useful to keep track of browser-scoped values, such as session IDs.
