Host — NestJS head-to-head

What it is responsible for

Host manages the entry points represented by

HostController

and

HostModule

, including

greeting

asyncGreeting

streamGreeting

, and

localPipe

. It also owns named services and classes including

HostService

UsersService

UserByIdPipe

, and

TestDto

. The evidence does not identify endpoint-to-service links, configuration, inputs, outputs, or execution order explicitly here.

What it needs, and who needs it

Host needs no dependencies from elsewhere in this repository.

Integration

needs Host: it is listed as depending on this subsystem. Without Host, Integration would lack that declared dependency, and

HostController

HostModule

, and

HostService

would not be available from it. 10 entities in

integration/hello-world/src/host

. 1 other subsystem depends on it, which makes it the 5th most depended-upon part of this codebase.

What it is made of

Its 10 entities sit in 6 files under

integration/hello-world/src/host

: 4 HTTP endpoints, 3 services, 1 controller, 1 module and 1 more.

host.controller.ts

holds 5 of them — more than any other file here.

Where work enters

1 controller publishes 4

GET

endpoints. None of them declares a guard.

Boundaries

1 other subsystem depends on this one —

Integration

. Changing what it exposes changes them. They hold 1 edge into it between them. What they reach is narrower than the folder: 1 of its 10 members carries every inbound edge —

HostModule

(1).

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