How phoolhbti/citraining works
<explanation>
1. Identify the project type and purpose
- This is an Adobe Experience Manager (AEM) multi‑module Maven project (“citraining”) that builds:
• OSGi bundles and Java back‑end logic (core, bundle, bundle‑taglib)
• JCR content and configs (content, ui.apps, ui.config, ui.content)
• Front‑end assets via Webpack (ui.frontend)
• Dispatcher configurations for Apache HTTP caching (dispatcher, dispatcher.ams)
• Integration and UI tests (it.tests, ui.tests)
2. Analyze the file structure
- Top‑level aggregator pom.xml ties together modules: all, core, content, ui.apps, ui.config, ui.content, ui.frontend, dispatchers, test modules.
- “core” contains OSGi services, servlets, filters, schedulers, Sling models.
- “bundle‑taglib” and “bundle” produce additional OSGi bundles for custom JSP taglibs.
- “content” holds generic content package definitions.
- “ui.apps” and “ui.content” deliver /apps and /conf JCR packages.
- “ui.config” delivers OSGi configurations under /apps/citraining/osgiconfig.
- “ui.frontend” compiles SCSS/JS into AEM clientlibs.
- “dispatcher” and “dispatcher.ams” produce Apache Dispatcher vhost/farm configs for on‑premise and AMS.
- “it.tests” runs JUnit ITs against AEM instances.
- “ui.tests” runs WebDriver/Selenium tests in containers (Docker compose).
3. Examine the README
- The README is minimal. Use module names and Maven lifecycle as source of architecture.
4. System design diagram instructions
a. Main components (draw each as distinct boxes):
– Developer/CI pipeline (Maven build agent)
– AEM Author instance
– AEM Publish instance
– Dispatcher (Apache HTTPD) in front of publish (and author if applicable)
– JCR repository (underlying CRX/Jackrabbit OAK)
– External services: Commerce GraphQL endpoint, FDM/Salesforce/Dynamics cloud configs
– Test environments (IT tests container, UI tests containers)
b. Relationships & interactions (use directional arrows):
– CI → Maven modules → AEM package deploy (ui.apps + content + config + core + bundles)
– UI.frontend → builds clientlibs → deployed into ui.apps
– Dispatcher → routes incoming HTTP(S) traffic → AEM publish → JCR repository
– Publish calls out → External GraphQL commerce service
– IT tests → invoke AEM servlets/Pages → validate responses
– UI tests → drive browser via WebDriver → hit Dispatcher → AEM
c. Architectural patterns & design principles
– Multi‑module Maven “feature‑oriented” packaging (separate OSGi, content, config, front‑end)
– OSGi micro‑services (servlets, schedulers, Sling models, filters)
– Client‑side asset pipeline with Webpack → AEM clientlibs
– Dispatcher as caching/reverse‑proxy layer
– Test modules for contract and end‑to‑end coverage
d. Technologies, frameworks, libraries
– Java / Sling / OSGi (Apache Felix)
– Sling Models, Sling Servlets, Filters, Schedulers
– Maven, Sling Maven Plugin, AEM Content Package Maven Plugin
– Webpack, Node, SCSS, TypeScript (in ui.frontend)
– Apache HTTPD + Dispatcher module
– JUnit + AEM Mocks + HttpUnit (for it.tests)
– WebDriverIO + Docker (for ui.tests)
5. Tailoring the diagram to this AEM project
- Emphasize separation of concerns:
* OSGi bundles vs. JCR content vs. front‑end assets vs. Dispatcher config
- Show the Maven aggregator building sub‑packages in proper order.
- Highlight how ui.frontend → ui.apps clientlibs interplay works.
- For Dispatcher.ams vs. on‑prem “dispatcher” module, show two deployment targets.
- For test modules, show them running in isolated containerized environments against AEM instance endpoints.
6. Diagram styling guidelines
- Use clear labels for each box (e.g., “core.jar”, “ui.apps package”, “AEM Publish”).
- Use arrows with labels (e.g., “deploy”, “HTTP GET/POST”, “GraphQL call”) for data flow.
- Color‑code component types:
* Blue for AEM modules (core, content, ui.apps, ui.config, ui.content)
* Green for front‑end build (ui.frontend)
* Orange for Dispatcher (dispatcher, dispatcher.ams)
* Gray for external services (Commerce GraphQL, FDM/Salesforce)
* Purple for test environments (it.tests, ui.tests)
- Use different shapes:
* Rectangles for runtime components (Author, Publish, Dispatcher)
* Cylinders for repositories or databases (JCR)
* Document icons for packages/artifacts
7. Detail and completeness
- Ensure every Maven module is represented, even if nested.
- Show the flow from source code → Maven build → AEM deployment → production runtime.
- Include both author and publish flows, plus dispatcher in front.
- Highlight external dependencies and configuration layers (ui.config).
- Represent test infrastructure separately, showing how they simulate end‑users or integrations.
By following these guidelines, you’ll produce a comprehensive, accurate diagram that captures the essential architecture of the citraining AEM project.
