Web Scraper Experimental Debug

URLs to start with

Request queue enables recursive crawling and the use of Pseudo-URLs, Link selector and context.enqueueRequest().

Pseudo-URLs to match links in the page that you want to enqueue. Combine with Link selector to tell the scraper where to find links. Omitting the Pseudo-URLs will cause the scraper to enqueue all links matched by the Link selector.

CSS selector matching elements with 'href' attributes that should be enqueued. To enqueue urls from

URL fragments (the parts of URL after a #) are not considered when the scraper determines whether a URL has already been visited. This means that when adding URLs such as https://example.com/#foo and https://example.com/#bar, only the first will be visited. Turn this option on to tell the scraper to visit both.

Function executed for each request

The jQuery library will be injected into each page. If the page already uses jQuery, conflicts may arise.

The Underscore.js library will be injected into each page. If the page already uses Underscore.js (or other libraries that attach to '_', such as Lodash), conflicts may arise.

Choose to use no proxy, Apify Proxy, or provide custom proxy URLs.

The provided cookies will be pre-set to all pages the scraper opens.

The scraper will use a real Chrome browser instead of a Chromium masking as Chrome. Using this option may help with bypassing certain anti-scraping protections, but risks that the scraper will be unstable or not work at all.

The scraper will apply various browser emulation techniques to match a real user as closely as possible. This feature works best in conjunction with the Use Chrome option and also carries the risk of making the scraper unstable.

Scraper will ignore SSL certificate errors.

Scraper will ignore CSP (content security policy) and CORS (cross origin resource sharing) settings of visited pages and requested domains. This enables you to freely use XHR/Fetch to make HTTP requests from the scraper.

Scraper will download media such as images, fonts, videos and sounds. Disabling this may speed up the scrape, but certain websites could stop working correctly.

Scraper will download CSS stylesheets. Disabling this may speed up the scrape, but certain websites could stop working correctly.

Maximum number of times the request for the page will be retried in case of an error. Setting it to 0 means that the request will be attempted once and will not be retried if it fails.

Maximum number of pages that the scraper will open. 0 means unlimited.

Maximum number of results that will be saved to dataset. The scraper will terminate afterwards. 0 means unlimited.

Defines how many links away from the StartURLs will the scraper descend. 0 means unlimited.

Defines how many pages can be processed by the scraper in parallel. The scraper automatically increases and decreases concurrency based on available system resources. Use this option to set a hard limit.

Maximum time the scraper will allow a web page to load in seconds.

Maximum time the scraper will wait for the page function to execute in seconds.

The scraper will wait until the selected events are triggered in the page before executing the page function. Available events are domcontentloaded, load, networkidle2 and networkidle0. See Puppeteer docs.

Debug messages will be included in the log. Use context.log.debug('message') to log your own debug messages.

Console messages from the Browser will be included in the log. This may result in the log being flooded by error messages, warnings and other messages of little value, especially with high concurrency.

Experimental implementation of Chrome debugger. In this mode the scraper will run with single browser on concurrency 1. You can place debugger; into your page function to set up a debugger breakpoint.

This object will be available on pageFunction's context as customData.
