Description

This Course in a NutshellIf you don’t know NestJs, it’s like Angular but for the backend. With it, we can write our backend using the same concepts and object-oriented APIs that we already use to structure our Angular frontend: components, services, modules, pipes, etc.NestJs is also quite similar to popular libraries that you might already be used to, such as, for example, the Spring library in the Java ecosystem, or ASP.NET MVC for the C# ecosystem.Course OverviewIn this course, you are going to learn from scratch how to design and develop a NestJs backend that will take the form of a REST API that queries a MongoDB database using the Mongoose ODM (Object Document Mapping) library. We will be providing a complete CRUD example showing how to perform the most common REST data retrieval and data modification operations using NestJs.No prior NestJs, MongoDB or Mongoose knowledge is assumed as we will explain everything from scratch. We will cover all the essential NestJs concepts such as Modules, Controllers and injectable services.We will learn in detail how to validate business data using a decorator based approach (with decorators like @IsString(), @IsPhoneNumber(), etc.) by leveraging the built-in NestJs Validation pipe.We will also implement using NestJs commonly needed backend security functionality such as User Authentication, RBAC (Role-Based Access Control) Authorization, error handling, and cover more advanced NestJs concepts such as Filters, Pipes, Guards, interceptors and middleware.Table of ContentsThis course covers the following topics:Introduction to NestJsRunning NestJs in Hot Reload and Debug modeWriting our first NestJs REST endpointNestJs Modules, Controllers and injectable ServicesIntroduction to MongoDBSetting up a cloud MongoDB databaseIntroduction to the Mongoose ODM libraryQuerying MongoDB from a NestJs REST endpointComplete CRUD example with NestJs and MongoDBNestJs Filters and custom error handlingNestJs Pipes, building a custom pipeData Validation with class-validator and the Validation pipeNestJs MiddlewareUser Authentication with NestJsNestJs RBAC (Role-Based Access Control) AuthorizationNestJs GuardsWhat Will You Learn In this Course?After taking this course, you will feel comfortable designing and developing applications using NestJs. You will have learned everything that you need to know in practice for designing and developing production-ready secure backends using the NestJs framework.
