Works’ talented software developer, Salman, recently featured in an interview to share his expert insights on Nest.JS – an incredibly widespread software framework. The discussion involved a detailed breakdown of the most commonly asked questions regarding the framework, offering valuable takeaways for the audience.
What precisely does Nest.JS entail?
Nest.JS is a sophisticated framework that streamlines the development of server-side Node.JS applications. It is constructed using TypeScript, which empowers developers to design applications that can be scaled up proficiently and tested thoroughly. By employing Nest.JS, developers can effortlessly create potent and sturdy applications.
Leveraging the Express.JS framework, Nest.JS provides an extensive range of pre-built APIs and features, allowing developers to build applications with minimal coding requirements. This is achievable due to the distinct properties of Nest.JS, which permits efficient application development.
Nest.JS is predominantly modelled on the Angular architecture, providing a well-organized environment comprising multiple files. This enables developers to dissect their work into separate modules, concentrating on one aspect at a time and exploiting their time more efficiently.
What sets Nest.JS apart from other frameworks?
Nest.JS boasts a streamlined structure and Command Line Interface (CLI) tools, simplifying the initial stages of development. Developers can formulate an entire new functionality with a single command. The Nest framework incorporates a module, controller, service, and testing stack to streamline the development process. Moreover, there are various templates and boilerplates available for any task. As it’s composed in TypeScript, Nest.JS is user-friendly for front-end developers, who lack experience in backend programming.
What is the difficulty level of learning Nest.JS?
Initially, developers must install the official documentation and Command Line Interface (CLI) via the npm packages. By utilising Nest.JS, users can benefit from secure coding practices. Additionally, the Nest framework can be augmented with third-party operators and plugins, opening up several possibilities. For instance, Passport.js can be utilised for authentication.
How does Nest.JS differ from Next.JS?
Next.JS is accountable for front-end development, which entails designing, creating text, animations, and graphics that are exposed to and interacted with by users. In contrast, Nest.JS is involved in the storage and administration of website data. For instance, when a Facebook post is accessed by a user, Next.JS caters to the text, animation and graphics, while Nest.JS delivers the backend code and data that enables the post to appear on the website’s front-end.
What are the fundamental principles of Nest.JS?
The fundamental principles of Nest.JS include:
- Organizing your code in a logical and reusable manner can be achieved by using modules. By grouping TypeScript files that relate to each other together and decorating them with the “@Module” decorator, you can supply Nest.js with metadata about your application’s architecture, making it simpler to organize and maintain.
- Providers: Providers serve to abstract away any complexity and logic. They allow you to create controllers and other providers that can be produced and inserted.
- Controllers: Incoming requests can be handled by controllers, which can provide appropriate responses to the client-side of your application (such as calling the API).
What sets Nest.JS server-side framework applications apart from client-side framework applications?
Client-side frameworks are applications that are executed directly within the user’s web browser. Conversely, server-side frameworks are programs that are processed on the server. Essentially, any website comprises two elements: the front-end, where the user interacts with the website, and the back-end, where data is sent and received from the server. Developers who specialise in server-side frameworks are tasked with developing, maintaining, and optimizing the code that facilitates the exchange of data between the front and back-ends. Meanwhile, front-end framework developers are responsible for creating visually appealing websites and applications that are replete with features.
When a customer visits an online store to buy shoes, they make use of the website’s front-end interface to make their selection. After selecting the desired item, adding it to their cart, and confirming the payment, the website captures this information and stores it in its server database. Subsequently, if the customer requests information about their delivery status, the server retrieves the required details, updates them with tracking data, and then displays the information on the front-end for the customer to view.
What are the advantages of using Nest.JS over Express.JS?
Nest.JS outperforms Express.JS by providing a comprehensive range of features and functionality that are not available with Express.JS. With Express.JS, developers must manually integrate third-party providers into their applications, whereas Nest.JS automates the process, saving time and effort.
Nest.js is a framework that takes advantage of Node.js’s capabilities, providing an abstraction layer that enhances speed and efficiency. Additionally, the framework includes access to a multitude of third-party modules, which helps to expedite development and improve the codebase with added robustness.
Nest.JS is an immensely versatile framework that permits developers to customise it with Object-Relational Mapping (ORM) tools like TypeORM. This enables developers to interact with databases using two common patterns: Active Record and Data Mapper. The Active Record pattern allows developers to simplify the code, while the Data Mapper pattern aids them in enhancing code maintainability.
What are some of the top features of Nest.JS?
Some of the key features of Nest.JS include:
- Nest.JS features a DI container (Dependency Injection) that improves the modularity and efficiency of applications.
- Support for Lazy Modules facilitates access to hundreds of modules that simplify integration with popular technologies, including TypeORM, Mongoose, GraphQL, Logging, Validation, Caching, WebSockets, and more. This makes it easy for users to stay up-to-date with the latest technologies, accelerating development and enhancing efficiency.
- Nest.JS allows for straightforward unit testing of applications.
- Nest.JS documentation is comprehensive.
What are microservices, and how can Nest.JS help with them?
Microservices is a architectural concept that views an application as a collection of interconnected services.
- Nest.JS is highly maintainable and testable.
- Nest.JS employs loose coupling.
- Nest.JS can be deployed independently.
- Nest.JS is designed with a focus on business capabilities.
- Nest.JS is governed by a small group of individuals.
Nest.JS microservices offer a convenient way to connect out of the box, without the need to use an Apache server’s ad port. Instead, developers can configure the microservices to use socket-based connections. This makes it straightforward to configure the microservices for the project, ensuring it performs as expected. Additionally, it is easy to expand and integrate the microservices with other elements of the project.
Nest.JS is an effective tool that helps develop lightweight and organized microservices, streamlining technology stack updates. Its built-in features and capabilities enable speedy, dependable creation, maintenance, and expansion of complex applications. One of the framework’s main advantages is its Dependency Injection implementation, which promotes code reuse by injecting one module into another, enabling more efficient and effective development processes.
