NestJS Zero to Hero – Modern TypeScript Back-end Development

NestJS Zero to Hero – Modern TypeScript Back-end Development

Develop and deploy enterprise back-end applications following best practices using Node.js and TypeScript

Created by Ariel Weinberger | 6.5 hours on-demand video course

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.
