Documentation

Overview

Package container exports nothing, and exists to say why.

There is no dependency injection container in this module. A type declares its collaborators as fields, a New function takes them as parameters, and the assembly is written out by hand in bootstrap/app.go. The interface is declared by the consumer rather than the provider, so a missing or mistyped collaborator is a build failure at the call site rather than a lookup that fails on the first request to reach it.

Nothing is shared unless a line of code shares it, so there is no registry to reset between tests, and a request-scoped value is a local variable in the handler goroutine that the garbage collector reclaims when the handler returns.
