NestJS is a progressive NodeJS framework for building efficient, reliable, and scalable server-side applications. It combines elements of object-oriented programming, functional programming, and functional reactive programming to provide a robust architecture for building server-side applications. This tutorial will guide you through the basics of NestJS, covering its key features, setup process, and building a simple application. In conclusion, in this article, we discussed the various skills that every Node JS developer should have. It ranges from Javascript proficiency as JS is the main base of Node JS and its knowledge is of utmost importance.
What can I expect to learn from NestJS courses?
We asked all learners to give feedback on our instructors based on the quality of their teaching style.
Experience with Frameworks
Master GraphQL concepts, tips & tricks, and everything you need to your own enterprise-grade GraphQL APIs. Learn BOTH (code-first & schema-first) approaches to creating GraphQL APIs with NestJS. Nest core team members can work directly with your team on a daily basis to help take your project to the next-level. Let us partner with you and your team to develop the most ambitious projects. Most of the modern web services depend Software engineering on RESTful APIs (Representational State Transfer). It is an interface that is used between two systems to securely exchange information across the internet.
Key Features of Nest.js:
There is no need to fill the application form in case you are paying online. Developers write controllers, services, and repositories to write a functionality. Dependency injection in NestJS is handled by the IoC (Inversion of Control) container. Services, controllers, and other classes can declare dependencies, which are then resolved and injected by NestJS. Middleware and interceptors can be used to handle cross-cutting concerns such as logging, authentication, and more.
- Its user-friendly nature, defined architecture, and straightforward Command Line Interface (CLI) tools make it an excellent choice, for beginners entering this domain.
- Real-time databases provide real-time synchronization between servers and clients.
- Angular is a rich frontend framework, usually combined with NodeJS for creating corporate applications.
- As an effective JavaScript framework for building user interfaces, ReactJS is used with Node JS to create applications with GUI.
- If you’re developing a real-time chat application or a large-scale eCommerce store, or even looking forward to hire the best NodeJS talents for your project then knowing about the NodeJS development skills is crucial.
- Install the necessary packages and configure TypeORM in your application module.
- Most of the modern web services depend on RESTful APIs (Representational State Transfer).

Mastering Backend Development with Nest.js
It now includes several improvements such as better formatting for deeply nested objects and arrays, support for maps and sets, and the ability to customize log prefixes. However, the standout feature is the new built-in support for JSON logging. Prometheus is an open-source monitoring and alerting system which mainly deals with time series data and metrics. Handlebars.js extends Mustache.js and provides for the creation of highly effective and highly functional templates.
- Knowledge of monitoring tools like Prometheus and Grafana is also an important skill for monitoring application load.
- The async/await feature helps write asynchronous code in a more synchronous, readable manner.
- Thus, developers should learn about cloud engineering as by using the cloud you can easily scale, ensure high availability, pay-as-per-use, and effectively collaborate with the DevOps environment.
- This comprehensive and advanced NestJS course will give learners an in-depth mastery of this versatile Node.js platform.
- Master the building blocks and essential concepts behind creating your own enterprise-grade applications.
- In Lesson 2, we’ll delve into middleware and exception filters, understanding their roles, implementing exception filters, and effectively putting all these concepts together in your NestJS applications.
- It is very similar thus you can enjoy creating while experiencing the same flexibility and less complexity.
Apache Kafka is a distributed platform for building real-time messaging systems that allows for the creation of real-time data pipelines. The Event Loop is the heart of NodeJS which makes asynchronous programming IO work by deferring tasks to a future time and then processing one at a time. Jest itself is a JavaScript testing framework that makes it quite easy for developers to test any JavaScript code. Security in NodeJS applications is important from vulnerability management and secure authentication to avoiding attack. PostgreSQL is a powerful, non-proprietary database that has many features including JSON support and full-text search. Vue.js is a lightweight front-end framework that can work ideally with NodeJS to develop scalable web applications.
Microservices architecture decomposes applications into small, self-contained services that interact with each other via APIs. With Docker, NodeJS applications can be easily packaged into containers, thus making the applications portable across the development, testing, and production stages. Mongoose is a MongoDB ORM that is used to define database schemas for querying in Node JS applications. MongoDB is one of the best NoSQL databases suitable for using vast amounts of data that has no specific structure.
