Testing Example

NestJS is built on top of the popular Express.js library and provides a modular and structured approach to building server-side applications.

You will take a hands-on approach to constructing a practical RESTful API from the ground up. By leveraging NestJS, TypeScript, and other technologies, you will delve into various topics, such as data modeling with TypeORM and MySQL, authentication and authorization mechanisms, request validation, error handling strategies, testing methodologies, deployment practices, and more.

By the end of this course, you will have gained the essential skills, knowledge, and hands-on experience necessary to build a real-world RESTful API. You will have learned how to scale your application using a public cloud, such as AWS, where your application can serve thousands and millions of customers cost-effectively. This comprehensive learning journey equips you to confidently navigate the intricacies of RESTful API development, ensuring you are well-prepared for NestJS development.
