Explanation:
A framework called Nest (NestJS) is used to create effective, scalable Node.js server-side applications. It mixes features of OOP (Object Oriented Programming), FP (Functional Programming), and FRP. It also employs progressive JavaScript, is built with and fully supports TypeScript (yet still allows developers to create in plain JavaScript) (Functional Reactive Programming).
Explanation:
Use NestJS to create a microservice that exposes a variety of different functions and events. There are certain restrictions, though. These choices are made available by NestJS using imprecise abstract message and event decorators. Instead of using the pre-built microservice abstraction, you should create your own service to describe your requirements. Although these decorators offer respectable validation, they have trouble capturing complex types.
Explanation:
A website that functions like a mobile app is known as a Progressive Web Application (PWA). Its icons are made to seem like those of a mobile application. Google News, Starbucks, and Twitter are a few well-known PWAs. These programs improve user interaction while using less data, which is crucial for people with sluggish connections and/or older technology.
Explanation:
One of the top Nodejs server-side frameworks of 2025, Loopback operates similarly to the Express framework. An extendable, TypeScript-based, open-source Node.js framework is the idea. Developers are given the flexibility to create APIs rapidly by implementing Loopback.
Explanation:
Commonly referred to as a "progressive web app," a progressive web application (PWA) is a sort of application software that is provided via the internet and is created using standard web technologies like HTML, CSS, JavaScript, and WebAssembly. It is designed to function on any device, including desktop and mobile ones, that has a standards-compliant browser.
Explanation:
With its logical, hierarchical structure, Nest JS advances web development. This makes it possible for programmers to create applications quickly and simply using a range of modules. A sizable community backs this framework and it is also very simple to use. Additionally, it includes 24-hour help, which is crucial if you run into any issues while creating or deploying a web application.
Explanation:
To make sure that your backend application is prepared to receive requests, use the health check mechanism. This is especially crucial for intricate programs with several dependencies. The Terminus package enables the implementation of health checks in NestJS apps. This package offers a unique REST endpoint that starts a service health check, which also checks system attributes and database connections. Additionally, it verifies the availability of resources, disk space, and other components.
