16. Create an IoC Container per module

Date: 2019-07-15

Log date: 2019-11-09

Status

Accepted

Context

For each module, when we process particular Command or Query, we need to resolve a graph of objects. We need to decide how dependencies of objects will be resolved.

Possible solutions

1. One IoC Container for whole application

One IoC container located in the host project.

Pros

  • standard approach
  • dependencies configured in one place

Cons

  • couples host application with all of projects, libraries
  • modules autonomy decreases
  • strong coupling

2. IoC Container per module

Multiple IoC containers per modules.

Pros

  • module autonomy
  • loose coupling
  • host application has dependency only to Application Service Layer

Cons

  • duplicated code
  • non-standard approach

Decision

Solution number 2 - IoC Container per module

IoC Container per module supports the autonomy of the module and louse coupling so this is a more important aspect for us than duplicated code in some places.

Consequences

  • Create and maintain an IoC Container for each module
  • Implementation is not standard, but still acceptable easy
  • We can add dependencies to module and other modules are intact
