TechBD Polyglot Monorepo

Welcome to the TechBD Polyglot Prime repository! This repository is the central hub for all bespoke code managed by Technology By Design (TechBD). Our goal is to maintain a well-organized, scalable, and efficient monorepo that supports our diverse range of projects and technologies.

Primary Languages and Frameworks

At TechBD, we focus on the following primary languages and frameworks for our enterprise and utility projects:

• Modern Java 21 LTS and above with Spring Boot 3.3 and above for all API and HTTP service-related use cases.
• Maven for project management.
• Thymeleaf for HTML templating and HTMX 2.0 for HATEOS interactions.
• OpenTelemetry (observability) and OpenFeature (feature flags).
• jOOQ with automatic code generation for type-safe SQL-first database interactions.
• PostgreSQL 16 for server-side persistence and SQLite for edge-side persistence.
• JUnit 5 with AssertJ assertions for testing the app server, Playwright for testing the front end, and pgTAP for testing the database.
• Deployment via containers
• Deno and TypeScript for utilities and scripting where Java may be too heavy.

Monorepo Strategy

Inspired by the practices at Microsoft, Google, and other large software companies, we have designed our monorepo strategy to facilitate collaboration, maintainability, and scalability. Here are the key aspects of our strategy:

1. Modular Structure: Each top-level directory represents a distinct project or service. This allows for clear separation of concerns and easy navigation.
2. Consistent Naming Conventions: Follow consistent naming conventions to make it easier to locate and manage code.
3. Shared Libraries: Common libraries and utilities will be placed in a shared directory to promote code reuse.
4. Version Control: Use Git submodules or subtree for managing third-party dependencies to keep the repository clean and manageable.
5. CI/CD Integration: Integrate Continuous Integration and Continuous Deployment (CI/CD) pipelines for automated testing and deployment.
6. Documentation: Each project will contain comprehensive documentation to assist developers in understanding and contributing to the codebase.

Project: TechBD Primary Hub

The hub-prime project is a Java Spring Boot application which serves FHIR API endpoints.

Project Setup

To set up the TechBD Hub project, follow these steps:

1. Clone the Repository:

   git clone https://github.com/tech-by-design/polyglot-prime.git
   cd polyglot-prime
   direnv allow               # apply the env vars
   cp .envrc.example .envrc   # assume the use of direnv
   vi .envrc                  # make sure to store secrets in ENV or Vault, not in Git
   cd hub-prime

2. Build the Project:

   mvn clean install

3. Run the Application:

   mvn spring-boot:run

4. Access the Application: Open your browser and navigate to http://localhost:8080.

Shared Libraries

• lib: Contains reusable utility functions and classes that can be used across different projects.

Supporting Work Products

• support contains all work products that support the above but do not make their way into production
