DDDplus

What is DDDplus?

DDDplus, originally cp-ddd-framework(cp means Central Platform：中台), is a lightweight DDD Enhancement Framework for complex business architecture.

It captures DDD missing concepts and patches the building block. It empowers building domain model with forward and reverse modeling. It visualizes the complete domain knowledge from code. It connects frontline developers with (architect, product manager, business stakeholder, management team). It makes (analysis, design, design review, implementation, code review, test) a positive feedback closed-loop. It strengthens building extension oriented flexible software solution. It eliminates frequently encountered misunderstanding of DDD via thorough javadoc for each building block with detailed example.

In short, the 3 most essential plus are:

1. provide extension point with multiple routing mechanism, suited for complex business scenarios
2. patch DDD building blocks for pragmatic forward modeling, clearing obstacles of DDD implementation
3. offer a reverse modeling DSL, visualizing complete domain knowledge from code

Current status

Used for several complex critical central platform projects in production environment.

Quickstart

Showcase

A full demo of DDDplus forward/reverse modeling ->

Forward modeling

<dependency>
    <groupId>io.github.dddplus</groupId>
    <artifactId>dddplus-runtime</artifactId>
</dependency>

Integration with SpringBoot

@SpringBootApplication(scanBasePackages = {"${your base packages}", "io.github.dddplus"})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
}

Reverse Modeling

<dependency>
    <groupId>io.github.dddplus</groupId>
    <artifactId>dddplus-visualization</artifactId>
</dependency>

Annotate your code With DSL, DDDplus can render domain model in multiple view.

class ReverseModelingTest {
    ReverseEngineeringModel model;
    @Test
    void visualizeDomainModel() {
        model = new DomainModelAnalyzer()
                        .scan("{your module root}")
                        .analyze();
        new PlantUmlRenderer()
            .build(model)
            .classDiagramSvgFilename("model.svg")
            .render(); // read-only searchable graph
        new PlainTextRenderer()
            .build(model)
            .targetFilename("model.txt")
            .render(); // mutable, integrated with forward modeling design process
        new CallGraphRenderer()
            .targetDotFilename("callgraph.dot")
            .build(model)
            .render(); // the call graph of your domain model
    }
}

Architecture Guard

<dependency>
    <groupId>io.github.dddplus</groupId>
    <artifactId>dddplus-enforce</artifactId>
    <scope>test</scope>
</dependency>

Enable it by writing unit test and integrate it with CI flow.

class ArchitectureGuardTest {
    @Test
    void enforcement() {
        new DDDPlusEnforcer()
                .scanPackages("${your base package}")
                .enforce();
    }
}
