Replace pageIdx with pageIds #688
Description
Is your feature request related to a problem? Please describe.
To provide stable ids for pages and enable interoperability with other tools, we propose replacing pageIdx with pageId based on the CDP's tab target ID.
With the Multiple Page Architecture in Chromium https://docs.google.com/document/d/1NginQ8k0w3znuwTiJ5qjYmBKgZDekvEPC22q0I4swxQ/edit?tab=t.0#heading=h.w1qo2n6sr8wn a single tab might host multiple page targets. Page targets are parented under a tab target that can be used to handle page activations.
Puppeteer's page API sits on top of the tab target meaning Puppeteer handles page activations for us. Therefore, the tab target seems like the best ID to use here.
Describe the solution you'd like
Using tab target IDs as a pageId.
Describe alternatives you've considered
- Using page target ID as a pageId.
- Creating a custom page ID.
