YAGNI likes a DRY KISS

Phase 1Modularization

To Do’s

❏ Identify Modules❏ Infrastructure | Core❏ Accounting❏ Portfolio

❏ Loan❏ Savings

❏ Office❏ Departments❏ Staff

❏ CRM❏ Create Projects

❏ Parent | Child❏ Adjust Dependencies

Phase 1.1API vs Internal

To Do’s

❏ Separate API❏ REST Resource❏ Command Model❏ Query Model❏ Service Interfaces

❏ Separate Internal❏ Service Implementation❏ Command Handler❏ Repositories❏ Module Configuration

Phase 2Spring & Plugins

To Do’s

❏ Main Spring Context provided via Infrastructure Module❏ Spring Java Config for Modules

❏ Naming Convention❏ e.g. org.mifos.module.*.config

❏ Spring’s build in Class Path Scanning❏ Use annotations to drive DI

❏ Component scan configured in module configuration❏ Add only module APIs as a compile time dependency

❏ Internals will be on the runtime class path

Phase 3Interception & Event Sourcing

To Do’s

❏ Provide Command Interceptions❏ Synchronous extensions❏ Consumer acts on workflow

❏ Provide Command Handler Events❏ Asynchronous extensions❏ Consumer reacts on workflow

❏ Provide registration mechanism❏ Interceptors❏ Event Listeners

Phase 4Preparing Archetypes

To Do’s

❏ Maven like archetype for Gradle❏ currently in specification

❏ Include❏ Infrastructure dependency❏ Testing framework❏ Project layout❏ Class skeletons for configuration❏ Ability to run | test drive in process

❏ Embedded Container (e.g. Jetty)❏ Embedded Database (e.g. H2)

Phase 5

SDK & JS-Library

To Do’s

❏ SDK❏ Bundle APIs and Archetypes❏ Provide proper documentation

❏ at least JavaDoc for all API components❏ a few How To’s

❏ Create a JS-Library❏ Provide proper documentation❏ a few How To’s

❏ jsfiddle?
