@crawlee/core

Core set of classes required for Crawlee.

The crawlee package consists of several smaller packages, released separately under @crawlee namespace:

Installing Crawlee​

Most of the Crawlee packages are extending and reexporting each other, so it's enough to install just the one you plan on using, e.g. @crawlee/playwright if you plan on using playwright - it already contains everything from the @crawlee/browser package, which includes everything from @crawlee/basic, which includes everything from @crawlee/core.

If we don't care much about additional code being pulled in, we can just use the crawlee meta-package, which contains (re-exports) most of the @crawlee/* packages, and therefore contains all the crawler classes.

npm install crawlee

Or if all we need is cheerio support, we can install only @crawlee/cheerio.

npm install @crawlee/cheerio

When using playwright or puppeteer, we still need to install those dependencies explicitly - this allows the users to be in control of which version will be used.

npm install crawlee playwright
# or npm install @crawlee/playwright playwright

Alternatively we can also use the crawlee meta-package which contains (re-exports) most of the @crawlee/* packages, and therefore contains all the crawler classes.

Sometimes you might want to use some utility methods from @crawlee/utils, so you might want to install that as well. This package contains some utilities that were previously available under Apify.utils. Browser related utilities can be also found in the crawler packages (e.g. @crawlee/playwright).
