Internationalization

31 Jan 202524 minutes to read

The Syncfusion Internationalization library is a robust tool for formatting and parsing date and number objects, leveraging official Unicode CLDR JSON data. By default, the en-US locale and USD currency code are preset for all Syncfusion Angular UI Components.

Loading CLDR-JSON Data

Syncfusion CLDR data package contains only JSON data files generated using the official Unicode CLDR JSON data. This helps users avoid utilizing the existing cldr-data package, which has third-party library vulnerabilities. The loadCldr function is required to load the following CLDR data for cultures other than en-US.

NOTE

Syncfusion CLDR data package is published based on the releases of the Unicode CLDR JSON data. The package will be published within a week after the official Unicode CLDR JSON data is released.

Individual file path reference

Syncfusion CLDR data can be loaded by referring to individual paths from the package below, such as:

File Name	Path
ca-gregorian	@syncfusion/ej2-cldr-data/main/en/ca-gregorian.json
timeZoneNames	@syncfusion/ej2-cldr-data/main/en/timeZoneNames.json
numbers	@syncfusion/ej2-cldr-data/main/en/numbers.json
currencies	@syncfusion/ej2-cldr-data/main/en/currencies.json
numberingSystems	@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json

Single file path reference

Syncfusion CLDR data can also be loaded by referring to a single path from the package below, such as:

File Name	Path
ca-gregorian, timeZoneNames, numbers, currencies	@syncfusion/ej2-cldr-data/main/en/all.json
numberingSystems	@syncfusion/ej2-cldr-data/supplemental/numberingSystems.json

Note: For en, dependency files are already loaded in the library.

Installing CLDR data

Syncfusion CLDR data is available as npm package. So, we can install it through below command to our package.

npm install @syncfusion/ej2-cldr-data

Binding to i18n library

The i18n library utilizes CLDR data to format and parse numbers and date/time values suitable for the en culture. Use the loadCldr function with enNumberData and enTimeZoneData as shown:

import { loadCldr } from '@syncfusion/ej2-base';
import enNumberData from "@syncfusion/ej2-cldr-data/main/en/numbers.json";
import entimeZoneData from "@syncfusion/ej2-cldr-data/main/en/timeZoneNames.json";

loadCldr(enNumberData, entimeZoneData);

Changing global Culture and Currency code

To update the default culture and currency code across all Syncfusion Angular UI Components, use setCulture and setCurrencyCode methods:

import {setCulture, setCurrencyCode} from '@syncfusion/ej2-base';

setCulture('ar');
setCurrencyCode('QAR');

Note: If global culture is not set, then en-US is set as the default locale, and USD is set as the default currency code.

Manipulating Numbers

Supported format string

Number formatting and parsing align with NumberFormatOptions. Specify relevant properties as illustrated:

No	Properties	Description
1	`format`	Denotes the format to be set .Possible values are 1. N - denotes numeric type 2. C - denotes currency type 3. P - denotes percentage type. Ex: `formatNumber`( 1234344 ,{format:'N4'}). >Note: If no format is specified it takes numeric as default format type.
2	`minimumFractionDigits`	Indicates the minimum number of fraction digits . Possible values are 0 to 20.
3	`maximumFractionDigits`	Indicates the maximum number of fraction digits. Possible values are 0 to 20.
4	`minimumSignificantDigits`	Indicates he minimum number of significant digits. Possible values are 1 to 21. >Note: If `minimumSignificantDigits` is given it is mandatory to give `maximumSignificantDigits`
5	`maximumSignificantDigits`	Indicates he maximum number of significant digits. . Possible values are 1 to 21. >Note: If `maximumSignificantDigits` is given it is mandatory to give `minimumSignificantDigits`
6	`useGrouping`	Indicates whether to enable the group separator or not . By default grouping value will be true.
7	`minimumIntegerDigits`	Indicates the minimum number of the integer digits to be placed in the value. Possible values are 1 to 21.
8	`currency`	Indicates the currency code which needs to considered for the currency formatting.

Note: The minimumIntegerDigits, minimumFractionDigits and maximumFractionDigits are categorized
as group one, minimumSignificantDigits and maximumSignificantDigits are categorized as group two.
If group two properties are defined, then group one properties will be ignored.

Custom number formatting and parsing

Custom number formatting and parsing can also be achieved by directly specifying the pattern in the format property of NumberFormatOptions. One or more of the custom format specifiers listed in the table below can be used to create custom number format.

Specifier	Description	Input	Format Output
0	Replaces the zero with the corresponding digit if one is present. Otherwise, zero appears in the result string.	`instance.formatNumber`(123,{format: ‘0000’ })	‘0123’
#	Replaces the “#” symbol with the corresponding digit if one is present; otherwise, no digit appears in the result string.	`instance.formatNumber`(1234,{format: ‘####’ })	‘1234’
.	Denotes the number of digits allowed after the decimal points if it’s not specified then no need to specify decimal point values.	`instance.formatNumber`(546321,{format: ‘###0.##0#’ })	‘546321.000’
%	Percent specifier denotes the percentage type format.	`instance.formatNumber`(1,{format: ‘0000 %’ })	‘0100 %’
$	Denotes the currency type format based on the global currency code specified.	`instance.formatNumber`(13,{format: ‘$ ###.00’ });	‘$ 13.00’
;	Denotes separate formats for positive, negative and zero values.	`instance.formatNumber`(-120,{format: ‘###.##;(###.00);-0’});	‘(120.00)’
‘String’ (single Quotes)	Denotes the characters enclosed within single Quote(‘) to be replaced in the resultant string.	`instance.formatNumber`(-123.44,{format: “####.## ‘@’”})	‘123.44 @’

Note: If a custom format pattern is specified, other NumberFormatOptions properties will not be considered.

Manipulating DateTime

Supported format string

Date formatting and parsing operations are performed based on the DateFormatOptions. You need to specify some or all of the following properties mentioned in the table below.

Options	Descriptions
Type	It specifies the type of format to be used supported types . 1. `date` 2. `dateTime` 3. `time` Based on the type specified the supported skeletons are given below 1. short 2. medium, 3. long 4. full Ex: `formatDate`(new Date(), {type: 'date', skeleton:medium}) >Note: If not type specified then date type is set by default
skeleton	Specifies the format in which the `dateTime` format will process

Date type skeletons

skeleton	Option input	Format Output
short	{type: 'date', skeleton:'short'})	11/4/16
medium	{type: 'date', skeleton:'medium'})	Nov 4, 2016
long	{type: 'date', skeleton:'long'}	November 4, 2016

Note: Culture specific format skeletons are also supported.

Custom formats

To use the custom date and time formats, we need to specify the date/time pattern directly in the format property.
A custom format string must contain one or more of the following standard date/time symbols.

Symbols	Description
G	Denotes the era in the date
y	Denotes the year.
M / L	Denotes month.
E / c	Denotes the day of week.
d	Denotes the day of month.
h / H	Denotes the hour. h for 12 hour and H for 24 hours format.
m	Denotes minutes.
s	Denotes seconds.
f	Denotes milliseconds.
a	Denotes the am/pm designator it will only be displayed if hour is specified in the h format.
z	Denotes the time zone.
’ (single quotes)	To display words in the formatted date you can specify the words with in the single quotes

Custom format example

import { Component } from '@angular/core';
import { Internationalization } from  '@syncfusion/ej2-base';

@Component({
    selector: 'app-root',
    templateUrl:`default.html`
})

export class AppComponent {
    ngAfterViewInit() {
        let intl: Internationalization = new Internationalization();
        let formattedString: string =  intl.formatDate(new Date('1/12/2014 10:20:33'), { format:'\'year:\'y' \'month:\' MM' });
        //Output: "year:2014 month:01"
    }
}

Note: If the format property is given as an option, other properties are not considered.

Date Parsing
