Desсription

NestJS is a Node.js back-end development framework built upon Express, leveraging the power of TypeScript.

NestJS leverages the incredible popularity and robustness of JavaScript as a language and Node.js as a technology. It is inspired by common libraries and frameworks such as Angular, React and Vue which improve developer productivity and experience.

Even considering the amount of superb libraries, helpers and tools that exist for server-side Node.js, none of them effectively solve the main problem - the architecture of an application.

NestJS provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled and easily maintainable applications.

Recently, the NestJS framework is gaining extreme popularity due to its incredible features;

• Leverages TypeScript - strongly typed language which is a super-set of JavaScript
• Simple to use, easy to learn and easy to master
• Powerful Command Line Interface (CLI) tool that boosts productivity and ease of development
• Detailed, well-maintained documentation
• Active codebase development and maintenance
• Open-source (MIT license)
• Supports dozens nest-specific modules that help you easily integrate with common technologies and concepts such as TypeORM, Mongoose, GraphQL, Logging, Validation, Caching, Websockets and much more
• Easy of unit-testing applications
• Made for Monoliths and Micro-services (entire section in the documentation regarding the Microservice type of a NestJS application, as well as techniques and recipes).

In this course I am going to guide you through the process of planning, developing and deploying a fully-featured back-end application, based on my experience developing and maintaining systems that support dozens of millions of concurrent users at scale.

Who this course is for

• Intermediate JavaScript developers who want to dive into back-end development
• Any developers willing to apply TypeScript on the back-end
• Developers eager to learn how to develop performant, secure and production-ready REST APIs following best practices
• Developers who want to learn how to deploy their application to the cloud (Amazon Web Services)
• Developers who want to follow building a practical, real-world application from zero to production
