2.0.3 / 2021/08/20

• BREAKING IN EDGE CASES - We removed forceUrlEncoding in requestAsBrowser because we found out that recent versions of the underlying HTTP client got already encode URLs and forceUrlEncoding could lead to weird behavior. We think of this as fixing a bug, so we're not bumping the major version.
• Limit handleRequestTimeoutMillis to max valid value to prevent Node.js fallback to 1.

• Use got-scraping 2.0.1 until fully compatible.

2.0.0 / 2021/08/05

• BREAKING: Require Node.js >=15.10.0 because HTTP2 support on lower Node.js versions is very buggy.

1.3.0 / 2021/07/11

Navigation hooks in CheerioCrawler

CheerioCrawler downloads the web pages using the requestAsBrowser utility function. As opposed to the browser based crawlers that are automatically encoding the URLs, the requestAsBrowser function will not do so. We either need to manually encode the URLs via encodeURI() function, or set forceUrlEncoding: true in the requestAsBrowserOptions, which will automatically encode all the URLs before accessing them.

We can either use forceUrlEncoding or encode manually, but not both - it would result in double encoding and therefore lead to invalid URLs.

We can use the preNavigationHooks to adjust requestAsBrowserOptions:

preNavigationHooks: [
    (crawlingContext, requestAsBrowserOptions) => {
        requestAsBrowserOptions.forceUrlEncoding = true;
    }
]

Apify class and Configuration

Adds two new named exports:

• Configuration class that serves as the main configuration holder, replacing explicit usage of environment variables.
• Apify class that allows configuring the SDK. Env vars still have precedence over the SDK configuration.

When using the Apify class, there should be no side effects. Also adds new configuration for WAL mode in ApifyStorageLocal.

As opposed to using the global helper functions like main, there is an alternative approach using Apify class. It has mostly the same API, but the methods on Apify instance will use the configuration provided in the constructor. Environment variables will have precedence over this configuration.

const { Apify } = require('apify'); // use named export to get the class

const sdk = new Apify({ token: '123' });
console.log(sdk.config.get('token')); // '123'

// the token will be passed to the `call` method automatically
const run = await sdk.call('apify/hello-world', { myInput: 123 });
console.log(`Received message: ${run.output.body.message}`);

Another example shows how the default dataset name can be changed:

const { Apify } = require('apify'); // use named export to get the class

const sdk = new Apify({ defaultDatasetId: 'custom-name' });
await sdk.pushData({ myValue: 123 });

is equivalent to:

const Apify = require('apify'); // use default export to get the helper functions

const dataset = await Apify.openDataset('custom-name');
await dataset.pushData({ myValue: 123 });

Full list of changes:

• Add Configuration class and Apify named export, see above.
• Fix proxyUrl without a port throwing an error when launching browsers.
• Fix maxUsageCount of a Session not being persisted.
• Update puppeteer and playwright to match stable Chrome (90).
• Fix support for building TypeScript projects that depend on the SDK.
• add taskTimeoutSecs to allow control over timeout of AutoscaledPool tasks
• add forceUrlEncoding to requestAsBrowser options
• add preNavigationHooks and postNavigationHooks to CheerioCrawler
• deprecated prepareRequestFunction and postResponseFunction methods of CheerioCrawler
• Added new event aborting for handling gracefully aborted run from Apify platform.

1.2.1 / 2021/05/14

• Fix requestAsBrowser behavior with various combinations of json, payload legacy options.

1.2.0 / 2021/05/10

This release brings the long awaited HTTP2 capabilities to requestAsBrowser. It could make HTTP2 requests even before, but it was not very helpful in making browser-like ones. This is very important for disguising as a browser and reduction in the number of blocked requests. requestAsBrowser now uses got-scraping.

The most important new feature is that the full set of headers requestAsBrowser uses will now be generated using live data about browser headers that we collect. This means that the "header fingeprint" will always match existing browsers and should be indistinguishable from a real browser request. The header sets will be automatically rotated for you to further reduce the chances of blocking.

We also switched the default HTTP version from 1 to 2 in requestAsBrowser. We don't expect this change to be breaking, and we took precautions, but we're aware that there are always some edge cases, so please let us know if it causes trouble for you.

Full list of changes:

• Replace the underlying HTTP client of utils.requestAsBrowser() with got-scraping.
• Make useHttp2 true by default with utils.requestAsBrowser().
• Fix Apify.call() failing with empty OUTPUT.
• Update puppeteer to 8.0.0 and playwright to 1.10.0 with Chromium 90 in Docker images.
• Update @apify/ps-tree to support Windows better.
• Update @apify/storage-local to support Node.js 16 prebuilds.

1.1.2 / 2021/04/10

• DEPRECATED: utils.waitForRunToFinish please use the apify-client package and its waitForFinish functions. Sorry, forgot to deprecate this with v1 release.
• Fix internal require that broke the SDK with underscore 1.13 release.
• Update @apify/storage-local to v2 written in TypeScript.

1.1.1 / 2021/03/23

• Fix SessionPoolOptions not being correctly used in BrowserCrawler.
• Improve error messages for missing puppeteer or playwright installations.

1.1.0 / 2021/03/19

In this minor release we focused on the SessionPool. Besides fixing a few bugs, we added one important feature: setting and getting of sessions by ID.

// Now you can add specific sessions to the pool,
// instead of relying on random generation.
await sessionPool.addSession({
    id: 'my-session',
    // ... some config
});

// Later, you can retrieve the session. This is useful
// for example when you need a specific login session.
const session = await sessionPool.getSession('my-session');

Full list of changes:

• Add sessionPool.addSession() function to add a new session to the session pool (possibly with the provided options, e.g. with specific session id).
• Add optional parameter sessionId to sessionPool.getSession() to be able to retrieve a session from the session pool with the specific session id.
• Fix SessionPool not working properly in both PuppeteerCrawler and PlaywrightCrawler.
• Fix Apify.call() and Apify.callTask() output - make it backwards compatible with previous versions of the client.
• Improve handling of browser executable paths when using the official SDK Docker images.
• Update browser-pool to fix issues with failing hooks causing browsers to get stuck in limbo.
• Removed proxy-chain dependency because now it's covered in browser-pool.

1.0.2 / 2021/03/05

• Add the ability to override ProxyConfiguration status check URL with the APIFY_PROXY_STATUS_URL env var.
• Fix inconsistencies in cookie handling when SessionPool was used.
• Fix TS types in multiple places. TS is still not a first class citizen, but this should improve the experience.

1.0.1 / 2021/02/03

• Fix dataset.pushData() validation which would not allow other than plain objects.
• Fix PuppeteerLaunchContext.stealth throwing when used in PuppeteerCrawler.

1.0.0 / 2021/01/25

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: 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.

0.22.1 / 2020/12/09

This is the last major release before SDK v1.0.0. We're committed to deliver v1 at the end of 2020 so stay tuned. Besides Playwright integration via a new BrowserPool, it will be the first release of SDK that we'll support for an extended period of time. We will not make any breaking changes until 2.0.0, which will come at the end of 2021. But enough about v1, let's see the changes in 0.22.0.

In this release we've changed a lot of code, but you may not even notice. We've updated the underlying apify-client package which powers all communication with the Apify API to version 1.0.0. This means a completely new API for all internal calls. If you use Apify.client calls in your code, this will be a large breaking change for you. Visit the client docs to see what's new in the client, but also note that we removed the default client available under Apify.client and replaced it with Apify.newClient() function. We think it's better to have separate clients for users and internal use.

Until now, local emulation of Apify Storages has been a part of the SDK. We moved the logic into a separate package @apify/storage-local which shares interface with apify-client. RequestQueue is now powered by SQLite3 instead of file system, which improves reliability and performance quite a bit. Dataset and KeyValueStore still use file system, for easy browsing of data. The structure of apify_storage folder remains unchanged.

After collecting common developer mistakes, we've decided to make argument validation stricter. You will no longer be able to pass extra arguments to functions and constructors. This is to alleviate frustration, when you mistakenly pass useChrome to PuppeteerPoolOptions instead of LaunchPuppeteerOptions and don't realize it. Before this version, SDK wouldn't let you know and would silently continue with Chromium. Now, it will throw an error saying that useChrome is not an allowed property of PuppeteerPoolOptions.

Based on developer feedback, we decided to remove --no-sandbox from the default Puppeteer launch args. It will only be used on Apify Platform. This gives you the chance to use your own sandboxing strategy.

LiveViewServer and puppeteerPoolOptions.useLiveView were never very user-friendly or performant solutions, due to the inherent performance issues with rapidly taking many screenshots in Puppeteer. We've decided to remove it. If you need similar functionality, try the devtools-server NPM package, which utilizes the Chrome DevTools Frontend for screen-casting live view of the running browser.

Full list of changes:

• BREAKING: Updated apify-client to 1.0.0 with a completely new interface. We also removed the Apify.client property and replaced it with an Apify.newClient() function that creates a new ApifyClient instance.

• BREAKING: Removed --no-sandbox from default Puppeteer launch arguments. This will most likely be breaking for Linux and Docker users.

• BREAKING: Function argument validation is now more strict and will not accept extra parameters which are not defined by the functions' signatures.

• DEPRECATED: puppeteerPoolOptions.useLiveView is now deprecated. Use the devtools-server NPM package instead.

• Added postResponseFunction to CheerioCrawlerOptions. It allows you to override properties on the HTTP response before processing by CheerioCrawler.

• Added HTTP2 support to utils.requestAsBrowser(). Set useHttp2 to true in RequestAsBrowserOptions to enable it.

• Fixed handling of XML content types in CheerioCrawler.

• Fixed capitalization of headers when using utils.puppeteer.addInterceptRequestHandler.

• Fixed utils.puppeteer.saveSnapshot() overwriting screenshots with HTML on local.

• Updated puppeteer to version 5.4.1 with Chrom(ium) 87.

• Removed RequestQueueLocal in favor of @apify/storage-local API emulator.

• Removed KeyValueStoreLocal in favor of @apify/storage-local API emulator.

• Removed DatasetLocal in favor of @apify/storage-local API emulator.

• Removed the userData option from Apify.utils.enqueueLinks (deprecated in Jun 2019). Use transformRequestFunction instead.

• Removed instanceKillerIntervalMillis and killInstanceAfterMillis (deprecated in Feb 2019). Use instanceKillerIntervalSecs and killInstanceAfterSecs instead.

• Removed the memory option from Apify.call options which was (deprecated in 2018). Use memoryMbytes instead.

• Removed delete() methods from Dataset, KeyValueStore and RequestQueue (deprecated in Jul 2019). Use .drop().

• Removed utils.puppeteer.hideWebDriver() (deprecated in May 2019). Use LaunchPuppeteerOptions.stealth.

• Removed utils.puppeteer.enqueueRequestsFromClickableElements() (deprecated in 2018). Use utils.puppeteer.enqueueLinksByClickingElements.

• Removed request.doNotRetry() (deprecated in June 2019) Use request.noRetry = true.

• Removed RequestListOptions.persistSourcesKey (deprecated in Feb 2020) Use persistRequestsKey.

• Removed the The function passed to Apify.main() threw an exception error message, because it was confusing to users.

• Removed automatic injection of charset=utf-8 in keyValueStore.setValue() to the contentType option.

0.22.0 / 2020/12/07

• Update default user agent to Chrome 86
• Bump Puppeteer to 5.3.1 with Chromium 86

0.21.7 / 2020/10/03

• Fix an error in PuppeteerCrawler caused by page.goto() randomly returning null.

0.21.6 / 2020/10/02

It appears that CheerioCrawler was correctly retiring sessions on timeouts and blocked status codes (401, 403, 429), whereas PuppeteerCrawler did not. Apologies for the omission, this release fixes the problem.

• Fix sessions not being retired on blocked status codes in PuppeteerCrawler.
• Fix sessions not being marked bad on navigation timeouts in PuppeteerCrawler.
• Update apify-shared to version 0.5.0.

0.21.5 / 2020/09/30

• Update the request serialization process which is used in RequestList to work with Node 10+.
• Update some TypeScript types that were preventing build due to changes in typed dependencies.

0.21.4 / 2020/09/02

The statistics that you may remember from logs are now persisted in key-value store, so you won't lose count when your actor restarts. We've also added a lot of useful stats in there which can be useful to you after a run finishes. Besides that, we fixed some bugs and annoyances and improved the TypeScript experience a bit.

• Add persistence to Statistics class and automatically persist it in BasicCrawler.
• Fix issue where inaccessible Apify Proxy would cause ProxyConfiguration to throw a timeout error.
• Update default user agent to Chrome 85

• Allow Apify.createProxyConfiguration to be used seamlessly with the proxy component of Actor Input UI.
• Fix integration of plugins into CheerioCrawler with the crawler.use() function.
• Fix a race condition which caused RequestQueueLocal to fail handling requests.
• Fix broken debug logging in SessionPool.
• Improve ProxyConfiguration error message for missing password / token.
• Update Puppeteer to 5.2.0
• Improve docs, update packages and so on.

0.21.0 / 2020/06/06

This release comes with breaking changes that will affect most, if not all of your projects. See the migration guide for more information and examples.

First large change is a redesigned proxy configuration. Cheerio and Puppeteer crawlers now accept a proxyConfiguration parameter, which is an instance of ProxyConfiguration. This class now exclusively manages both Apify Proxy and custom proxies. Visit the new proxy management guide

We also removed Apify.utils.getRandomUserAgent() as it was no longer effective in avoiding bot detection and changed the default values for empty properties in Request instances.

• BREAKING: Removed Apify.getApifyProxyUrl(). To get an Apify Proxy url, use proxyConfiguration.newUrl([sessionId]).
• BREAKING: Removed useApifyProxy, apifyProxyGroups and apifyProxySession parameters from all applications in the SDK. Use proxyConfiguration in crawlers and proxyUrl in requestAsBrowser and Apify.launchPuppeteer.
• BREAKING: Removed Apify.utils.getRandomUserAgent() as it was no longer effective in avoiding bot detection.
• BREAKING: Request instances no longer initialize empty properties with null, which means that:
  • empty errorMessages are now represented by [], and
  • empty loadedUrl, payload and handledAt are undefined.
• Add Apify.createProxyConfiguration() async function to create ProxyConfiguration instances. ProxyConfiguration itself is not exposed.
• Add proxyConfiguration to CheerioCrawlerOptions and PuppeteerCrawlerOptions.
• Add proxyInfo to CheerioHandlePageInputs and PuppeteerHandlePageInputs. You can use this object to retrieve information about the currently used proxy in Puppeteer and Cheerio crawlers.
• Add click buttons and scroll up options to Apify.utils.puppeteer.infiniteScroll().
• Fixed a bug where intercepted requests would never continue.
• Fixed a bug where Apify.utils.requestAsBrowser() would get into redirect loops.
• Fix Apify.utils.getMemoryInfo() crashing the process on AWS Lambda and on systems running in Docker without memory cgroups enabled.
• Update Puppeteer to 3.3.0.

0.20.4 / 2020-05-11

• Add Apify.utils.waitForRunToFinish() which simplifies waiting for an actor run to finish.
• Add standard prefixes to log messages to improve readability and orientation in logs.
• Add support for async handlers in Apify.utils.puppeteer.addInterceptRequestHandler()
• EXPERIMENTAL: Add cheerioCrawler.use() function to enable attaching CrawlerExtension to the crawler to modify its behavior. A plugin that extends functionality.
• Fix bug with cookie expiry in SessionPool.
• Fix issues in documentation.
• Updated @apify/http-request to fix issue in the proxy-agent package.
• Updated Puppeteer to 3.0.2

0.20.3 / 2020-04-14

• DEPRECATED: CheerioCrawlerOptions.requestOptions is now deprecated. Please use CheerioCrawlerOptions.prepareRequestFunction instead.
• Add limit option to Apify.utils.enqueueLinks() for situations when full crawls are not needed.
• Add suggestResponseEncoding and forceResponseEncoding options to CheerioCrawler to allow users to provide a fall-back or forced encoding of responses in situations where websites serve invalid encoding information in their headers.
• Add a number of new examples and update existing ones to documentation.
• Fix duplicate file extensions in Apify.utils.puppeteer.saveSnapshot() when used locally.
• Fix encoding of multi-byte characters in CheerioCrawler.
• Fix formatting of navigation buttons in documentation.

0.20.2 / 2020-03-09

• Fix an error where persistence of SessionPool would fail if a cookie included invalid expires value.
• Jumping a patch version because of an error in publishing via CI.

0.20.0 / 2020-03-03

• BREAKING: Apify.utils.requestAsBrowser() no longer aborts request on status code 406 or when other than text/html type is received. Use options.abortFunction if you want to retain this functionality.
• BREAKING: Added useInsecureHttpParser option to Apify.utils.requestAsBrowser() which is true by default and forces the function to use a HTTP parser that is less strict than default Node 12 parser, but also less secure. It is needed to be able to bypass certain anti-scraping walls and fetch websites that do not comply with HTTP spec.
• BREAKING: RequestList now removes all the elements from the sources array on initialization. If you need to use the sources somewhere else, make a copy. This change was added as one of several measures to improve memory management of RequestList in scenarios with very large amount of Request instances.
• DEPRECATED: RequestListOptions.persistSourcesKey is now deprecated. Please use RequestListOptions.persistRequestsKey.
• RequestList.sources can now be an array of string URLs as well.
• Added sourcesFunction to RequestListOptions. It enables dynamic fetching of sources and will only be called if persisted Requests were not retrieved from key-value store. Use it to reduce memory spikes and also to make sure that your sources are not re-created on actor restarts.
• Updated stealth hiding of webdriver to avoid recent detections.
• Apify.utils.log now points to an updated logger instance which prints colored logs (in TTY) and supports overriding with custom loggers.
• Improved Apify.launchPuppeteer() code to prevent triggering bugs in Puppeteer by passing more than required options to puppeteer.launch().
• Documented BasicCrawler.autoscaledPool property, and added CheerioCrawler.autoscaledPool and PuppeteerCrawler.autoscaledPool properties.
• SessionPool now persists state on teardown. Before, it only persisted state every minute. This ensures that after a crawler finishes, the state is correctly persisted.
• Added TypeScript typings and typedef documentation for all entities used throughout SDK.
• Upgraded proxy-chain NPM package from 0.2.7 to 0.4.1 and many other dependencies
• Removed all usage of the now deprecated request package.

• BREAKING: Node 8 and 9 are no longer supported. Please use Node 10.17.0 or higher.
• DEPRECATED: Apify.callTask() body and contentType options are now deprecated. Use input instead. It must be of content-type: application/json.
• Add default SessionPool implementation to BasicCrawler.
• Add the ability to create ad-hoc webhooks via Apify.call() and Apify.callTask().
• Add an example of form filling with Puppeteer.
• Add country option to Apify.getApifyProxyUrl().
• Add Apify.utils.puppeteer.saveSnapshot() helper to quickly save HTML and screenshot of a page.
• Add the ability to pass got supported options to requestOptions in CheerioCrawler thus supporting things such as cookieJar again.
• Switch Puppeteer to web socket again due to suspected pipe errors.
• Fix an issue where some encodings were not correctly parsed in CheerioCrawler.
