Plural API

import { enPlural } from '~/plural/en'; // use plural generator

export const approvalsLeftPlural = enPlural.create({
	one: '# approval',
	other: '# approvals',
	'=': {
		'1': 'one approval',
	},
});

approvalsLeftPlural(0); // 0 approvals
approvalsLeftPlural(1); // one approval
approvalsLeftPlural(2); // 2 approvals

Dictionary

cfg-default-locale.ts

import { i18n, setDefaultLocale } from '@artifact-project/i18n';

// 1. Open https://artifact-project.github.io/i18n/
// 2. Choice a plural preset 


// Dictionary
const dict = {
	required: 'No empty',
	minLength: ({detail: {min}}, {plural}) => `Minimum ${plural('symbols', min)}`,
	symbols: {
		cardinal: {
			one: 'symbol',
			other: 'symbols',
		},
	},
};

// Set default
setDefaultLocale(new i18n(dict, plural));

somewhere.ts

import {T} from '@artifact-project/i18n';

T('required'); // No empty
T({id: 'minLength', detail: {min: 6}}); // Minimum 6 symbols
T('inline', {inline: 'Wow'}); // Wow
