ngrx is a state management library for Angular applications.

• ngrx follows the Redux pattern for managing application state

• It uses actions, reducers, and selectors to manage state changes

• State changes are handled immutably to ensure predictability and maintainability

NGRX can handle large amounts of data by using lazy loading, pagination, and memoization techniques.

• Implement lazy loading to only load data when needed

• Use pagination to limit the amount of data loaded at once

• Utilize memoization to cache results and avoid unnecessary computations

NodeJS is a runtime environment that allows you to run JavaScript on the server side.

• NodeJS is built on Chrome's V8 JavaScript engine.

• It uses an event-driven, non-blocking I/O model.

• NodeJS is commonly used for building server-side applications and APIs.

• npm (Node Package Manager) is used for managing dependencies in NodeJS projects.

Used a modular architecture with Angular services, components, and modules.

• Implemented services to handle business logic and data retrieval

• Created reusable components for UI elements

• Organized code into feature modules for better maintainability

SOLID principles are a set of five design principles that help make software more maintainable, flexible, and scalable.

• Single Responsibility Principle (SRP) - Each class should have only one reason to change.

• Open/Closed Principle (OCP) - Classes should be open for extension but closed for modification.

• Liskov Substitution Principle (LSP) - Objects of a superclass should be replaceable with objects of its subclasses with...read more

Angular performance optimization involves using best practices to improve the speed and efficiency of Angular applications. ngOnChanges is a lifecycle hook in Angular that is called when a data-bound input property value changes.

• Use trackBy function in ngFor to improve performance when rendering lists

• Lazy load modules to reduce initial load time

• Minimize the use of two-way data binding to avoid unnecessary change detect...read more
