Angular ECMAScript Intl

Contains pipes to transform internationalization data using Intl.* browser APIs.

Getting started

Install the package:

npm install angular-ecmascript-intl --save

Import the pipes individually as per usage, or import the IntlModule to import all pipes at once.

By default, all pipes will use the browser default locale. If you want to override it, you can provide the INTL_LOCALES injection token:

import { NgModule } from "@angular/core";
import { INTL_LOCALES } from "angular-ecmascript-intl";

@NgModule({
  providers: [
    {
      provide: INTL_LOCALES,
      useValue: "de-DE",
    },
  ],
})
export class MyModule {}

Also, every pipe accepts the locale option.

Now you can use the pipes, see below.

Pipes

• Date pipe
• Decimal pipe
• Percent pipe
• Currency pipe
• Language pipe
• Country pipe
• Unit pipe
• List pipe
• Relative Time (timeago) pipe

Date pipe

Use the date pipe like the following:

{{myDate | intlDate: options}}

The input date can be one of the following:

• Date object
• number (UNIX timestamp)
• string (will be parsed by new Date() constructor)
• null
• undefined

The following options are supported:

• dateStyle
• timeStyle
• hour12

With the INTL_DATE_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Decimal pipe

Use the decimal pipe like the following:

{{1.24 | intlDecimal: options}}

The input can be one of the following:

• number
• string (must be parseable as number)
• null
• undefined

The following options are supported:

• notation
• signDisplay
• minimumIntegerDigits
• minimumFractionDigits
• maximumFractionDigits
• minimumSignificantDigits
• maximumSignificantDigits

With the INTL_DECIMAL_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Percent pipe

Use the percent pipe like the following:

{{0.24 | intlPercent: options}}

The input can be one of the following:

• number
• string (must be parseable as number)
• null
• undefined

The following options are supported:

• notation
• signDisplay
• minimumIntegerDigits
• minimumFractionDigits
• maximumFractionDigits
• minimumSignificantDigits
• maximumSignificantDigits

With the INTL_PERCENT_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Currency pipe

Use the currency pipe like the following:

{{1.24 | intlCurrency: 'USD': options}}

The input can be one of the following:

• number
• string (must be parseable as number)
• null
• undefined

The currency code parameter is required and must be a valid ISO 4217 currency code. If you want to transform a decimal number instead, use the intlDecimal pipe.

The following additional options are supported:

• currencyDisplay
• currencySign
• notation
• signDisplay
• minimumIntegerDigits
• minimumFractionDigits
• maximumFractionDigits
• minimumSignificantDigits
• maximumSignificantDigits

With the INTL_CURRENCY_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Language pipe

Use the language pipe like the following:

{{'en-US' | intlLanguage: options}}

The input can be one of the following:

• string (must be a BCP 47 IETF language tag)
• null
• undefined

The following option is supported:

• languageDisplay

With the INTL_LANGUAGE_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Country pipe

Use the country pipe like the following:

{{'US' | intlCountry: options}}

The input can be one of the following:

• string (must be two-letter ISO 639-1 language code or a three-letter ISO 639-2 language code)
• null
• undefined

Unit pipe

Use the unit pipe like the following:

{{1.2 | intlUnit: 'hour': options}}

The input can be one of the following:

• number
• string (must be parseable as number)
• null
• undefined

The unit parameter is required, see the specification for a full list of possible values. If you want to transform a decimal number instead, use the intlDecimal pipe.

The following additional options are supported:

• unitDisplay
• notation
• signDisplay
• minimumIntegerDigits
• minimumFractionDigits
• maximumFractionDigits
• minimumSignificantDigits
• maximumSignificantDigits

With the INTL_UNIT_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

List pipe

Use the list pipe like the following:

{{['my', 'items'] | intlList: options}}

The input can be one of the following:

• Iterable of strings
• null
• undefined

The following options are supported:

• type
• style

With the INTL_LIST_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Relative Time (timeago) pipe

The relative time format will format the input date compared to the current date in a "timeago" format. Every minute, the value will be updated automatically.

Use the relative time pipe like the following:

{{myDate | intlRelativeTime: options}}

The input date can be one of the following:

• Date object
• number (UNIX timestamp)
• string (will be parsed by new Date() constructor)
• null
• undefined

The following options are supported:

• numeric
• style

With the INTL_RELATIVE_TIME_PIPE_DEFAULT_OPTIONS injection token you can specify default options.

Browser compatibility

This library supports the latest major version of the following browsers:

• Chrome
• Firefox
• Safari

For each of those browsers, unit tests are being performed regularly.

In case you need to support older versions of that browsers, see the below table with the minimum required browser version for each pipe:

Pipe	Chrome	Firefox	Safari
Date	24	29	10
Number	24	29	10
Percent	24	29	10
Currency	24	29	10
Language	81	86	14.1
Country	81	86	14.1
Unit	77	78	14.1
List	72	78	14.1
Relative Time	71	65	14
