Hi @kokoc
@kokoc The PR that creates a new endpoint for getting a single product by ID.
Could you, please, review the PR?
Thanks!

@nrkapoor I believe we should move this issue to GraphQL project.

New query works on both: Magento & Catalog Storefront

What's the difference between "Magento" and "Catalog Storefront"?

[mslabko]

@DrewML "Magento" has a lot of meanings, including "Catalog Storefront". It may be "B2C", "Community edition", "B22"... But first of all this is our product ;)

"Catalog storefront" is just a set of extensions (modules) that bring new behavior to Magento and in current state is in a deep development phase

[DrewML]

"Magento" has a lot of meanings, including "Catalog Storefront". It may be "B2C", "Community edition", "B22"... But first of all this is our product ;)

Right, you're confirming that the acceptance criteria is ambiguous. "Magento" is a brand, I'm trying to understand what we really mean (assuming PHP monolith?)

[mslabko]

I think you need to ask in some general channel - you will have 100500 definitions :)

From my understanding, it depends on the conversation context. In terms of "Storefront" topic (again - need definitions, I mean SF Application which we are working on) by "Magento" we often mean our produce as backend system / PIM. But sometimes we can mean just a vanilla set of core modules... So yeah we need to have ONE glossary and use the same definitions

[DrewML]

@mslabko not talking about in general here, this is about this specific story and its acceptance criteria.

Perhaps it's better to rephrase: instead of "what's the difference," let's go with "which systems does this query need to work in"

[mslabko]

@DrewML I believe this task must be split into 2 tasks. Current PR in progress should go to "Magento" - magneto/magento2ce repo

And after implementation, we can handle second criteria in a separate task for CatalogStorefront.
