Message Formatting

This feature allows you to format messages with placeholders that can be replaced with dynamic values. The example demonstrates loading a translation, activating a locale, and formatting a message with a dynamic name.

const { i18n } = require('@lingui/core');
const { setupI18n } = require('@lingui/core');

const i18n = setupI18n();
i18n.load({
  en: {
    message: 'Hello, {name}!'
  }
});
i18n.activate('en');

const message = i18n._('message', { name: 'John' });
console.log(message); // Output: Hello, John!

Locale Management

This feature allows you to manage different locales and switch between them. The example shows how to load translations for multiple locales and activate a specific locale to get the translated message.

const { i18n } = require('@lingui/core');
const { setupI18n } = require('@lingui/core');

const i18n = setupI18n();
i18n.load({
  en: { message: 'Hello' },
  fr: { message: 'Bonjour' }
});
i18n.activate('fr');

const message = i18n._('message');
console.log(message); // Output: Bonjour

Custom Pluralization Rules

This feature allows you to define custom pluralization rules for different languages. The example demonstrates how to use pluralization in a message based on the count value.

const { i18n } = require('@lingui/core');
const { setupI18n } = require('@lingui/core');

const i18n = setupI18n();
i18n.load({
  en: {
    message: '{count, plural, one {# item} other {# items}}'
  }
});
i18n.activate('en');

const message = i18n._('message', { count: 5 });
console.log(message); // Output: 5 items
