Breaking change: Puppeteer no longer uses Node’s EventEmitter library
As part of our work to make Puppeteer agnostic of its environment we are removing the dependency on Node’s EventEmitter in favour of an event emitter that is not tied to Node. Under the hood we use Mitt, but we extend Mitt with additional functionality to match most of the methods that Node’s EventEmitter provides. The following methods have been removed from Puppeteer classes that extend EventEmitter:
eventNames()
getMaxListeners()
listeners(eventName)
prependListener
prependOnceListener
setMaxListeners(n)
rawListeners(eventName)
Additionally all the static methods on the EventEmitter class are not supported:
listenerCount(emitter, eventName)
defaultMaxListeners
errorMonitor
Node’s EventEmitter emitted a newListener event when a listener was added and a removeListener event when one was removed. These are not supported and will not be emitted.
New features and improvements
Send/receive debug logs are now split out into separate channels making the logs much clearer (#6017)
You can now call isJavaScriptEnabled() on a Puppeteer page to find out if JS is enabled on the page (#5993)
Bug fixes
Puppeteer is now much better at killing lingering browser processes, especially when you exit a test run with Ctrl-C (#6011)
Behind the scenes
We've started work on a new documentation system that uses TSDoc to generate documentation from our source code and have been porting documentation into code accordingly.
