Cats

concept
1 min readUpdated

What it is responsible for

Cats manages the Cats-oriented GraphQL entry points reached through CatsModule. It connects query members getCats and cat, mutation member createCat, and subscription member catCreated with the named Cats symbols CatsResolvers, CatsService, and Cat. Query, Mutation, and Subscription identify the operation groupings represented in this subsystem. CatsGuard and CatsRequestScopedService are also named parts of the Cats area.

What it needs, and who needs it

Within this repository, Cats has no recorded dependencies. The integration subsystem depends on Cats, so its Cats-related integration path requires CatsModule to remain available as the work entry point. Without this subsystem, the recorded Cats GraphQL members, including getCats and createCat, are unavailable to that dependent path. No further external requirements or failure behavior are evidenced by the supplied subsystem evidence here.

14 entities in integration/graphql-schema-first/src/cats. 1 other subsystem depends on it, which makes it the 12th most depended-upon part of this codebase.

What it is made of

Its 14 entities sit in 7 files under integration/graphql-schema-first/src/cats: 4 graphql types, 3 services, 2 graphql querys, 1 module and 4 more. cats.types.graphql holds 8 of them — more than any other file here. CatsResolvers declares 4 methods, the widest surface here.

Boundaries

1 other subsystem depends on this oneIntegration. Changing what it exposes changes them.

They hold 4 edges into it between them. What they reach is narrower than the folder: 1 of its 14 members carries every inbound edge — CatsModule (4).

It depends on no other subsystem in this repository — it is a leaf.
