I'll guide you on how to install the NestJS CLI globally on your machine.
An overview of the project for this course - the Task Management application.
Creating the Task Management NestJS project using the NestJS CLI.
Introduction to NestJS Providers and Services.
The first part is about creating the service method to create a new task.
The second part is about handling a POST request in the TasksController, extracting the body parameters and calling the service method to create a new task.
Introduction to the concept of Data Transfer Objects, or DTOs.
In this challenge you'll have to combine all you've learned so far and add the functionality of deleting a task by ID.
Use the knowledge gained so far to add support for updating a task's status.
- Having basic knowledge of TypeScript is recommended, but not required
NestJS is a Node.js back-end development framework built upon Express, leveraging the power of TypeScript.
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;
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.
- 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
