Launching multiple browser instances and manage events

[mhaseebkhan]

I am working on a project which involves a multi-user scenario.

The use-case is such that multiple users can hit an end-point for information which involves launching puppeteer and browsing through various URLs.

In the implementation, if the puppeteer instance launched completes its end to end execution in one go for a single user, then, everything works great, however, if there is a puppeteer execution in process and another request comes in which tries to use the same codebase, then, everything breaks. Even the first request isn't completed.

My question is from a design and implementation perspective as what are the best practices recommended by the puppeteer community to tackle multi-user scenarios. Any examples will certainly be very helpful.

I have tried using BrowserContext as well, using which, I can open multiple browser windows, however, as soon as the second browser window is opened, events for the first one are swallowed.

How can I launch multiple browser windows such that each window is responsible for handling and managing its respective events?

@aslushnikov: Your input in this regard will be highly appreciated.

@mhaseebkhan I don't quite follow this scenario. Can you come up with a small runnable script that illustrates the issue?

@aslushnikov: Here is a test script containing a README with instructions.

Please have a look and suggest.
