When it comes to distributed microservices/cloud architectures, the lightweight factor is essential — from both the engineer and customer perspective. Built on top of Express.JS, Nest.JS offers multiple functionalities and out-of-the-box APIs. Developers can leverage the features of Nest.JS to build applications with less code.
In addition, with APIs, our team liked exposing a new entity than they have in their model, and NestJS was good for class layers. The reason our engineering team chose NestJS is because the NestJS framework checked their three key boxes, is highly customizable, has extensive documentation, and has a broad community of followers. Providers are fundamental to Nest — a provider can be injected as a dependency to create relationships between various objects.
The first day of my solo project
What are some of the core concepts of Nest.JS?
If you have an application that requires you to use Hapi, go for it. NestJS uses strong HTTP server frameworks like Express and Fastify that provide a degree of abstraction over major Node.js frameworks. But, they also expose their APIs to the developer directly, allowing developers to use the plethora of third-party modules available for the underlying platform. All you need to start the development is to set up a new app and you are ready to go.
If something doesn’t come from within one specific module, it can’t really be accessed in other parts of the application. Single responsibility is enforced, making it easier for project growth across a team. As a development platform for multiple devs in various teams, NestJS provides standard guidelines for each member to prevent chaos and ensure high code quality. This defined, standardised architecture results in an easily maintainable codebase.
- This method sends a message to the microservice, and the send method will wait until the microservice successfully completes the operation and sends back a response before returning.
- In this article, we’ll explore Nest.js and what you can build with it.
- Here, we’ll list different reasons to select Nest.js as your Node.js framework for upgrading or building your next project.
- Despite its capabilities, devs realised that NodeJS itself required a framework because it was too plain and simple.
- You can create countless types of applications with Node.js; you’re only limited by your applications’ features.
I get that sails is closest to rails, but that’s not particularly a priority. NestJS is an exciting server-side framework that supports many components such as pipes, interceptors, middleware, exception filters, etc. However, being relatively new to the web development world, Nest has its fair share of drawbacks and areas for improvement.
Defining NestJS and How to Get Started
A few other things we like about Nest applications is that the framework is more opinionated than Express, another Node.js framework, or TSOA, which is good for a growing team. Nest offers a lot of flexibility with its Guards and custom Decorators, plus they have more context than basic middleware. Finally, with Nest decorators, our engineers can define our MongoDB schema alongside our types which preserves compatibility.
NestJS has its own rules and is not only for backend development. The framework is DDD-friendly, Event sourced, and offers microservice architecture. It provides the engineering team with standard development architecture and industry best practices. With it, developers can abstract away repeated engineering processes to focus solely on developing the business logic.
