After 3.5 years of rapid development, and a lot of breaking changes and deprecations, here comes the result - Apify SDK v1. There were two goals for this release. Stability and adding support for more browsers - Firefox and Webkit (Safari).

The SDK has grown quite popular over the years, powering thousands of web scraping and automation projects. We think our developers deserve a stable environment to work in and by releasing SDK v1, we commit to only make breaking changes once a year, with a new major release.

We added support for more browsers by replacing PuppeteerPool with browser-pool. A new library that we created specifically for this purpose. It builds on the ideas from PuppeteerPool and extends them to support Playwright. Playwright is a browser automation library similar to Puppeteer. It works with all well known browsers and uses almost the same interface as Puppeteer, while adding useful features and simplifying common tasks. Don't worry, you can still use Puppeteer with the new BrowserPool.

A large breaking change is that neither puppeteer nor playwright are bundled with the SDK v1. To make the choice of a library easier and installs faster, users will have to install the selected modules and versions themselves. This allows us to add support for even more libraries in the future.

Thanks to the addition of Playwright we now have a PlaywrightCrawler. It is very similar to PuppeteerCrawler and you can pick the one you prefer. It also means we needed to make some interface changes. The launchPuppeteerFunction option of PuppeteerCrawler is gone and launchPuppeteerOptions were replaced by launchContext. We also moved things around in the handlePageFunction arguments. See the migration guide for more detailed explanation and migration examples.

What's in store for SDK v2? We want to split the SDK into smaller libraries, so that everyone can install only the things they need. We plan a TypeScript migration to make crawler development faster and safer. Finally, we will take a good look at the interface of the whole SDK and update it to improve the developer experience. Bug fixes and scraping features will of course keep landing in versions 1.X as well.

Full list of changes:

  • BREAKING: Removed puppeteer from dependencies. If you want to use Puppeteer, you must install it yourself.
  • BREAKING: Removed PuppeteerPool. Use browser-pool.
  • BREAKING: Removed PuppeteerCrawlerOptions.launchPuppeteerOptions. Use launchContext.
  • BREAKING: Removed PuppeteerCrawlerOptions.launchPuppeteerFunction. Use PuppeteerCrawlerOptions.preLaunchHooks and postLaunchHooks.
  • BREAKING: Removed args.autoscaledPool and args.puppeteerPool from handle(Page/Request)Function arguments. Use args.crawler.autoscaledPool and args.crawler.browserPool.
  • BREAKING: The useSessionPool and persistCookiesPerSession options of crawlers are now true by default. Explicitly set them to false to override the behavior.
  • BREAKING: Apify.launchPuppeteer() no longer accepts LaunchPuppeteerOptions. It now accepts PuppeteerLaunchContext.

New deprecations:

  • DEPRECATED: PuppeteerCrawlerOptions.gotoFunction. Use PuppeteerCrawlerOptions.preNavigationHooks and postNavigationHooks.

Removals of earlier deprecated functions:

  • BREAKING: Removed Apify.utils.puppeteer.enqueueLinks(). Deprecated in 01/2019. Use Apify.utils.enqueueLinks().
  • BREAKING: Removed autoscaledPool.(set|get)MaxConcurrency(). Deprecated in 2019. Use autoscaledPool.maxConcurrency.
  • BREAKING: Removed CheerioCrawlerOptions.requestOptions. Deprecated in 03/2020. Use CheerioCrawlerOptions.prepareRequestFunction.
  • BREAKING: Removed Launch.requestOptions. Deprecated in 03/2020. Use CheerioCrawlerOptions.prepareRequestFunction.

New features:

  • Added Apify.launchPlaywright(launchContext) helper function.
  • Added browserPoolOptions to PuppeteerCrawler to configure BrowserPool.
  • Added crawler to handle(Request/Page)Function arguments.
  • Added browserController to handlePageFunction arguments.
  • Added crawler.crawlingContexts Map which includes all running crawlingContexts.
