Building APIs doing TDD in Node and Typescript (and Jest)

Learn to build a robust REST API with Node.js, TypeScript, and Jest using Test-Driven Development (TDD)! This comprehensive course guides you through the entire process of creating a single-use secret storage application, modeled after the popular One Time Secret site.

We'll dive deep into Test-Driven Development, specifically the Inside-Out TDD approach (also known as Classicist or Chicago School TDD). This means we'll begin by writing tests before writing the code, building outwards from the core functionality and ensuring every aspect of our API is thoroughly tested at all times.

Here's what you'll master:

• REST API Development: Build a fully functional REST API from the ground up.
• Node.js & TypeScript: Gain practical experience with these powerful technologies for backend development.
• Jest Testing Framework: Learn to write effective unit and integration tests to ensure code quality.
• Test-Driven Development (TDD): Master the principles and practice of TDD for building reliable software.
• Inside-Out TDD: Implement the Inside-Out TDD methodology for a structured and test-focused development process.
• MongoDB Persistence: Utilize MongoDB as a database to store and retrieve secrets.
• Application Design: Learn to design well-structured and maintainable applications.
• Domain-Driven Design (DDD): Explore DDD principles to model your application's domain effectively.
• Hexagonal Architecture: Understand and apply Hexagonal Architecture for creating loosely coupled and testable code.
• CQRS (Command Query Responsibility Segregation): Gain insights into CQRS patterns for optimizing data access and application performance.

We'll start by analyzing the business requirements – a secure application for storing and retrieving secrets with a single-use access mechanism. You'll learn how to translate these requirements into clean, well-crafted code, all while maintaining complete control over your production code through continuous testing.

This course is designed for developers looking to enhance their API development skills and gain a deeper understanding of modern software architecture. A special thanks to @Panos for valuable feedback that helped shape this course!
