About the course

In this lesson, we’ll provide an overview of this course’s content, intended audience, and learning objectives.

This course introduces the exciting world of RESTful APIs with NestJS. We’ll learn how to create a real-world RESTful API, secure it, write sufficient tests, and deploy the app to Amazon Web Services (AWS).

In today’s rapidly changing digital world, RESTful APIs are the backbone of web and mobile applications. NestJS offers a structured and scalable approach to building RESTful APIs, making development faster and more efficient. NestJS is used for building RESTful APIs by large companies, like Adidas, Autodesk, GitLab, and IBM, as well as numerous startups and other enterprises worldwide. Mastering NestJS equips learners with a skill set that is highly sought by employers.

Prerequisites and intended audience

This course targets developers who know basic JavaScript (or TypeScript) and web development concepts. While prior experience with NodeJS is advantageous, it’s not a strict prerequisite.

Whether someone is a junior developer eager to explore RESTful API development or an experienced programmer seeking to harness the power of NestJS, this course is designed to equip learners with the knowledge and practical skills needed to create secure and scalable web application programming interfaces (APIs).

Course objectives

In this course, we’ll walk through the development process step by step, ensuring that we clearly understand all of the concepts and learn how to apply this knowledge with hands-on coding.

We’ll delve into the following:

  • NestJS fundamentals: We’ll gain a solid understanding of NestJS, its architecture, and the powerful tools it provides for building modern web APIs.

  • RESTful API design: We’ll learn how to design RESTful APIs, adhering to best practices and industry standards to create efficient and user-friendly APIs.

  • Database integration: We’ll explore database integration using MySQL, which is a popular relational database management system, and TypeORM, which is a powerful object-relational mapping (ORM) framework.

  • Authentication and security: We’ll cover how to implement secure authentication methods to protect our APIs and user data.

  • Validation and serialization: We’ll discover how to validate incoming data and serialize outgoing responses, ensuring data integrity and consistency.

  • Testing strategies: We’ll master the art of writing unit tests and end-to-end (E2E) tests to ensure the reliability and correctness of our NestJS applications. E2E testing is a testing method that evaluates the functionality of an entire application to ensure it works correctly from start to finish.

  • Deployment to AWS: We’ll learn how to deploy our NestJS applications to AWS for real-world use.
