ngx-numeral - TypeScript

ngx-numeral is a library written in TypeScript that allows programmers to easily format numbers in their Angular applications. This library is a wrapper around the Numeral.js library, which is a powerful and flexible number formatting library.

Installation

To install ngx-numeral, you can use npm:

npm install ngx-numeral --save

Features

ngx-numeral offers a number of features to help programmers format numbers in their applications. Some of the key features include:

• Pipe: ngx-numeral provides a pipe that can be used to format numbers in templates.

• Directive: ngx-numeral also provides a directive that can be used to format numbers in HTML elements.

• Service: In addition to the pipe and directive, ngx-numeral also provides a service that can be used to format numbers programmatically.

Furthermore, Numeral.js provides a number of formatting options that ngx-numeral exposes to programmers. These options allow programmers to format numbers in a wide variety of ways, such as:

• Currency: Format numbers as currency.
• Percentages: Format numbers as percentages.
• Time: Format numbers as time.
• Bytes: Format numbers as bytes.
• Custom Formats: Format numbers in any custom way using Numeral.js syntax.

Usage

Pipe

To use the ngx-numeral pipe, first, import the NumeralPipeModule:

import { NumeralPipeModule } from 'ngx-numeral';

@NgModule({
  imports: [
    // Other modules...
    NumeralPipeModule
  ],
  // ...
})
export class AppModule { }

Once the pipe is imported, it can be used in templates as follows:

<p>{{ 10000 | numeral: '0,0.00' }}</p>

This would output 10,000.00.

Directive

To use the ngx-numeral directive, first, import the NumeralDirectiveModule:

import { NumeralDirectiveModule } from 'ngx-numeral';

@NgModule({
  imports: [
    // Other modules...
    NumeralDirectiveModule
  ],
  // ...
})
export class AppModule { }

Once the directive is imported, it can be used in HTML elements as follows:

<p [numeral]="'0,0.00'">{{ 10000 }}</p>

This would output <p>10,000.00</p>.

Service

To use the ngx-numeral service, first, import the NumeralService:

import { NumeralService } from 'ngx-numeral';

@Component({...})
export class MyComponent {
  constructor(private numeralService: NumeralService) {}
  formatNumber(value: number, format: string): string {
    return this.numeralService.format(value, format);
  }
}

With the service imported, it can then be used to format numbers programmatically:

<p>{{ formatNumber(10000, '0,0.00') }}</p>

This would output 10,000.00.

Conclusion

In conclusion, ngx-numeral is a powerful, flexible library that allows programmers to easily format numbers in their Angular applications. With its pipe, directive, and service, ngx-numeral provides multiple ways to format numbers, making it a must-have tool for any Angular developer who needs to work with numbers.
