Key Insights

• 🚾 Building a REST API from scratch involves defining the API, setting up the project structure, and implementing the necessary endpoints for CRUD operations.
• 🔠 Separating the API definition and logic into separate projects allows for better modularity and versioning of the API.
• 😣 Using the .NET CLI and Visual Studio Code provides a streamlined development experience for building the REST API.
• 🎨 Following principles from domain-driven design and functional programming can improve the resilience and organization of the application.
• 🏛️ Resilience and error handling are crucial aspects of building a scalable API, requiring explicit definition and handling of errors.
• 👨‍💼 By enforcing business rules on the internal service models, the API can ensure the validity and consistency of data.

Questions & Answers

Q: What is the main objective of this course?

The course aims to teach beginners how to build a CRUD-based REST API from scratch using .NET, with a focus on creating, reading, updating, and deleting breakfast items in the Uber Breakfast application.

Q: What technologies are used in the course?

The course utilizes .NET 6, the .NET CLI, and Visual Studio Code as the main technologies for building the REST API.

Q: What architecture choices are made in building the REST API?

The REST API follows a CRUD-based architecture, allowing for the creation, reading, updating, and deleting of resources. The focus is on building a system suitable for small to medium-sized applications, incorporating concepts from functional programming and domain-driven design.

Q: How are errors and exceptions handled in the API?

The course demonstrates an approach to error handling using the erroror library, which allows for explicit representation of errors and better control over error flows. The API returns appropriate error responses to clients based on the specific errors encountered.
