Visual Studio Projektmappe strukturieren [Mit Anleitung]

Summary

The transcript provides a detailed guide on setting up and structuring a project in a layered architecture using PlayStation and PHP. It emphasizes the importance of organizing project files, namespaces, and components effectively. The speaker walks through creating different layers such as logic, data storage, and cross-cutting concerns, and highlights best practices for naming conventions and handling dependencies. They also discuss the repository pattern for data management and demonstrate setting up a sample project with person management functionalities, including handling adult and child data separately.

Takeaways

• 📂 The speaker emphasizes the importance of structuring projects with a clear architecture, recommending a layered approach for business applications.
• 🔍 When starting a project, the speaker suggests using a 'solution' to lay out the initial structure, which can help in organizing different components and functionalities.
• 🛠️ The speaker discusses the use of 'namespaces' for organizing code in a logical and navigable manner, which should reflect the project's folder structure and complexity.
• 🏗️ The speaker recommends creating folders for each layer of the architecture, including a 'cross-cutting' folder for functionalities that span across different layers.
• 📝 The speaker introduces the concept of 'data classes' and 'behavior classes', explaining that data classes should be simple and reflect real-world entities, while behavior classes handle the logic.
• 🔑 The speaker explains the use of the 'Repository Pattern' in the data layer for managing data access and separation of concerns.
• 👥 The speaker uses 'Person Management' as an example to demonstrate how to create and structure components within a project, including the creation of data classes and repositories.
• 🔄 The speaker highlights the importance of keeping the project's namespace structure aligned with the folder structure for ease of navigation and maintenance.
• 🛑 The speaker mentions the use of 'Just Namespace' as a feature to see which files are affected by changes, which is crucial for maintaining a clean project structure.
• 📈 The speaker touches on the topic of 'domain complexity' and how the project's complexity should be oriented around the domain's complexity, suggesting a video for further explanation.
• 🔍 The speaker advises on naming conventions for classes and components, suggesting the use of patterns like 'Manager' for classes that handle specific entities and functionalities.

Q & A

What is the first step recommended when starting a project?

The first step recommended is to create a blank solution and structure your project accordingly, considering the architecture you will use.

Why is it important to adjust the namespaces after creating a project?

Adjusting the namespaces is important to maintain organization and clarity within the project, ensuring that classes are appropriately categorized and easier to navigate.

What is the difference between vertical and horizontal layers in a multi-layer architecture?

Vertical layers refer to different components such as business logic or data access, while horizontal layers represent the structure within those components, like specific functionalities or modules.

What are some examples of components you might create in a multi-layer architecture?

Examples include logic components, data storage components, and cross-cutting components for functionalities that span across different layers.

Why is it important to correlate namespace structure with folder structure?

Correlating namespace structure with folder structure helps in maintaining project complexity at a manageable level, making it easier to navigate and maintain the codebase.

How should you name data classes in a project?

Data classes should be named after the real-world entities they represent to maintain clarity and relevance, such as 'Person' for a class representing a person.

What is the repository pattern and why is it useful?

The repository pattern is a way to abstract data access logic, making it easier to manage and test by providing a central place for data operations.

What should you do after creating a new component in your project?

After creating a new component, it is important to immediately adjust the namespaces to ensure consistency and organization within the project.

Why is it important to structure your project into layers and components?

Structuring a project into layers and components helps in separating concerns, making the codebase more modular, maintainable, and scalable.

What approach should you take if you have components that need to share data?

If components need to share data, it is recommended to use a shared module or cross-cutting layer where common data classes can reside, ensuring that all relevant components can access the shared data.
