Welcome to your guide on how to kick off your journey with Wow, a state-of-the-art microservice framework built on Domain-Driven Design (DDD) and Event Sourcing. The architecture is designed to respond efficiently to complex business requirements while ensuring that your applications are scalable and perform optimally. Let’s dive into the steps to get you started!
Prerequisites
- A basic understanding of Domain-Driven Design (DDD)
- Familiarity with Command Query Responsibility Segregation (CQRS)
- Knowledge of Event Sourcing
- Experience with Reactive Programming
Quick Start with Wow Project Template
To quickly create a DDD project using the Wow framework, you can utilize the Wow Project Template. This template is straightforward to use and will streamline the initial setup process.
Exploring Wow’s Features
Wow’s architecture is built around several key features. Here’s a quick overview:
- Domain-Driven, Event-Driven, and Test-Driven approaches
- Declarative Design principles
- Integration with Reactive Programming for responsiveness
- Thorough testing with over 80% test coverage
Understanding the Architecture
The architecture of Wow can be visualized like a bustling city. Each component represents a building or facility that serves a specific purpose within the ecosystem:
- Domain Models: These are your skyscrapers, housing the primary functions and data.
- Commands and Events: Think of these as the roads and traffic systems, enabling information and actions to flow smoothly.
- Event Sourcing: This acts as the city’s archive, maintaining the history of each action that has shaped the environment.
Performance Testing
Wow has features that facilitate performance testing, crucial for ensuring that your application can handle real-world demands. For example, after performing stress tests on the “Add To Shopping Cart” feature, you may find:
- Average Transactions per Second (TPS) of 59,625
- Peak TPS reaching 82,312
- Average response time of 29 ms
This performance ensures that your application remains responsive under load.
Deployment Options
Wow supports deployment across a variety of platforms, including Redis, MongoDB, and Kafka. Configuration files for each of these can be found in the deployment instruction section of the documentation.
Testing Your Implementation
Every implementation should be rigorously tested. The built-in test suite allows you to easily check for at least 80% test coverage using the Given-When-Expect format. This ensures robust quality assurance throughout your development process.
Troubleshooting
As with any framework, you might encounter challenges. Here are a few common troubleshooting tips:
- Issue: Commands not processing as expected.
Solution: Check your command handling configuration, ensure that your handlers are correctly registered. - Issue: Poor performance during tests.
Solution: Verify your architecture setup and optimize database calls. Consider reviewing your event sourcing strategy. - Issue: Integration setup issues.
Solution: Make sure all dependencies and configurations are correctly set up as per the documentation.
