Free NestJS Basic Question and Answers

Question 1

What framework help JS developers manage code more efficiently?

Accepted Answer

Angular

Answer

Angular is a comprehensive front-end framework that provides a highly structured and opinionated approach to building complex web applications. Its component-based architecture, strong typing with TypeScript, and extensive tooling help JavaScript developers manage large codebases more efficiently. This structured environment promotes maintainability and scalability, making code management easier.

Question 2

What does Passport.js do?

Accepted Answer

Authentication

Answer

Passport.js is a popular and flexible authentication middleware for Node.js. It provides a modular framework for adding various authentication strategies, such as local username/password, OAuth, and JWT, to web applications. Its primary function is to handle user authentication and session management, making it easier to secure applications.

Question 3

What does a website's back end include?

Accepted Answer

Data

Answer

The backend of a website encompasses the server-side logic, databases, and application programming interfaces (APIs) that power the application. Its core responsibility is to store, organize, and process data, which is then delivered to the frontend for display and user interaction. Therefore, 'data' is a fundamental component of a website's backend.

Question 4

What does Nest.JS provide for developers to get started?

Accepted Answer

Module, controller, service and a testing pile

Answer

NestJS provides a clear and structured starting point for developers, typically including fundamental building blocks like modules, controllers, and services. These components form the core of its architectural pattern. Additionally, NestJS integrates well with testing frameworks and often includes a basic testing setup ('testing pile') out of the box, encouraging robust development practices from the start.

Question 5

What type of experience does it take to use the Nest framework?

Accepted Answer

Front-end development

Answer

While NestJS is a backend framework, its architecture and design principles are heavily inspired by Angular, a prominent front-end framework. Developers with experience in front-end development, especially with Angular, will find NestJS's use of decorators, dependency injection, and modular structure very familiar. This makes the transition to backend development with NestJS smoother for those with a front-end background.
