Getting Started

Installing and Importing

Install the package by command:

    npm install ngx-currency --save

Import the directive

import { NgxCurrencyDirective } from "ngx-currency";

@Component({
  standalone: true,
  selector: "app-root",
  templateUrl: "./app.component.html",
  imports: [NgxCurrencyDirective],
})
export class AppComponent {}

Using

<input type="tel" currencyMask formControlName="value" />

• ngModel An attribute of type number. If is displayed '$ 25.63', the attribute will be '25.63'.

Options

You can set options...

<!-- example for pt-BR money -->
<input
  currencyMask
  formControlName="value"
  [options]="{ prefix: 'R$ ', thousands: '.', decimal: ',' }"
/>

Available options:

• align - Text alignment in input. (default: right)
• allowNegative - If true can input negative values. (default: true)
• decimal - Separator of decimals (default: '.')
• precision - Number of decimal places (default: 2)
• prefix - Money prefix (default: '$ ')
• suffix - Money suffix (default: '')
• thousands - Separator of thousands (default: ',')
• nullable - when true, the value of the clean field will be null, when false the value will be 0
• min - The minimum value (default: undefined)
• max - The maximum value (default: undefined)
• inputMode - Determines how to handle numbers as the user types them (default: Financial)

Input Modes:

• Financial - Numbers start at the highest precision decimal. Typing a number shifts numbers left. The decimal character is ignored. Most cash registers work this way. For example:
  • Typing '12' results in '0.12'
  • Typing '1234' results in '12.34'
  • Typing '1.234' results in '12.34'
• Natural - Numbers start to the left of the decimal. Typing a number to the left of the decimal shifts numbers left; typing to the right of the decimal replaces the next number. Most text inputs and spreadsheets work this way. For example:
  • Typing '1234' results in '1234'
  • Typing '1.234' results in '1.23'
  • Typing '12.34' results in '12.34'
  • Typing '123.4' results in '123.40'

You can also set options globally...

import { provideEnvironmentNgxCurrency, NgxCurrencyInputMode } from 'ngx-currency';

bootstrapApplication(AppComponent, {
  providers: [
    ...
    provideEnvironmentNgxCurrency({
      align: "right",
      allowNegative: true,
      allowZero: true,
      decimal: ",",
      precision: 2,
      prefix: "R$ ",
      suffix: "",
      thousands: ".",
      nullable: true,
      min: null,
      max: null,
      inputMode: NgxCurrencyInputMode.Financial,
    }),
    ...
  ],
}).catch((err) => console.error(err));

• Install local dev dependencies: npm install while current directory is this repo

Development server

Run npm start to start a development server.

Testing

• Run npm test to run tests

When running in the Chrome browser, you can set code breakpoints to debug tests using these instructions:

• From the main Karma browser page, click the Debug button to open the debug window
• Press ctrl + shift + i to open Chrome developer tools
• Press ctrl + p to search for a file to debug
• Enter a file name like input.handler.ts and click the file
• Within the file, click on a row number to set a breakpoint
• Refresh the browser window to re-run tests and stop on the breakpoint
