Learn a practical testing setup for Node.js and TypeScript using Jest and Supertest. This guide covers unit tests, mocks, and integration testing to help you build reliable, maintainable APIs with confidence.
Learn how to Dockerize a Node.js Express API using multi-stage builds and test it locally with Docker Compose before deploying to production.
Learn how to write integration tests for Node.js and Express APIs using Jest and Supertest. Test middleware, validation, error handling, and improve coverage with real-world examples.
Most Node.js developers write state-based unit tests and stop there. While those tests are important, they don’t tell the full story. Real-world applications are made of collaborating modules, and if those collaborations break, your app breaks.
In this article, we’ll walk through how to deploy a full-stack Next.js task manager application to an Amazon EC2 instance on AWS. The application uses Amazon Cognito for authentication and includes a simple CRUD system powered by MongoDB.
In this guide, I’ll walk you through how to unit test an Express API in Node.js, using practical examples from a Task Manager project.
Struggling with the limits of single inheritance? Discover how the TypeScript Mixins pattern allows you to compose multiple behaviors into a single class. Learn how to combine generics and inheritance to build flexible, reusable traits like a pro.
Generics are a fundamental feature of statically-typed languages. They allow developers to pass types as parameters to another type, function, or structure.
Stop struggling with messy Node.js code. Discover how to use TypeScript interfaces and inheritance to build scalable, maintainable projects. Learn senior-level strategies to enforce structure and reuse code efficiently.
tructure your Node.js projects for scalability. Learn how TypeScript classes enable Object-Oriented Programming (OOP) for type-safe, modular code.
