How to create class in Angular Project?

In Angular, TypeScript is the primary language for writing code. One of the fundamental concepts in TypeScript is classes, which allow you to define blueprints for creating objects with properties and methods. In this article, we’ll explore how to create classes in Angular projects and understand their significance in building robust applications.

Understanding Classes in TypeScript

Classes in TypeScript follow the same syntax as classes in other object-oriented programming languages like Java or C#. They serve as templates for creating objects with predefined properties and methods.

Basic syntax for defining a class in TypeScript:

export class ClassName {
  property1: Type;
  property2: Type;

  constructor(param1: Type, param2: Type) {
    this.property1 = param1;
    this.property2 = param2;
  }

  method(): ReturnType {
    // Method logic
  }
}

Benefits of Using Classes in Angular Projects

• Encapsulation: Classes encapsulate related properties and methods, making code more organized and maintainable.
• Reusability: Once defined, classes can be used multiple times throughout the project, promoting code reuse.
• Inheritance: TypeScript supports class inheritance, allowing classes to inherit properties and methods from parent classes, facilitating code hierarchy.
• Type Safety: TypeScript’s static typing ensures type safety when working with class properties and method parameters, reducing runtime errors.

Steps to Create a class in the angular project:

Step 1: Open the command prompt and install angular using this command:

npm install -g @angular/cli

Step 2: open vs code and open new terminal and create new angular project ,give the name like gfg.

ng new gfg

Configure the project as given:

Step 3: Use the following command for create class:

ng g class gfg

create class

After that 2 files named: gfg.spec.ts and gfg.ts created

gfg.spec.ts

By following these methods you have successfully created the class component.
