puppeteer 3.2.0

v3.2.0

on Node.js NPM

Highlights

• We now support emulating vision deficiency types within Puppeteer using page.emulateVisionDeficiency. You can read more about these on the DevTools update blog post.

• We now use Mitt as the Event Emitter that backs many of Puppeteer's classes rather than the EventEmitter module that ships with Node. This is potentially a breaking change if you rely on some of the less popular EventEmitter methods as Puppeteer's EventEmitter does not support the entire suite of NodeJS EventEmitter functions. We think it's unlikely anyone has relied on these; we were able to swap out the EventEmitter in Puppeteer without any unit tests needing to change.

• Puppeteer now recognises webviews as regular pages which means you can control them just like you would control a regular page.

Behind the scenes

• The Request class has been renamed to HTTPRequest to avoid a clash with TypeScript's Request type. We'll be making similar changes to Response and Worker. This is not a breaking change as Puppeteer doesn't directly expose these classes so you shouldn't be referring to them by name in your code.
