Basic Translation

This feature allows you to define translations for different locales and switch between them. The code sample demonstrates how to create a context with messages in English and French, and how to switch the locale to get the translated message.

const { createCoreContext, translate } = require('@intlify/core-base');

const ctx = createCoreContext({
  locale: 'en',
  messages: {
    en: {
      hello: 'Hello, world!'
    },
    fr: {
      hello: 'Bonjour, le monde!'
    }
  }
});

console.log(translate(ctx, 'hello')); // Output: Hello, world!
ctx.locale = 'fr';
console.log(translate(ctx, 'hello')); // Output: Bonjour, le monde!

Message Formatting

This feature allows you to use placeholders in your messages and replace them with dynamic values. The code sample shows how to define a message with a placeholder and provide a value for it during translation.

const { createCoreContext, translate } = require('@intlify/core-base');

const ctx = createCoreContext({
  locale: 'en',
  messages: {
    en: {
      greeting: 'Hello, {name}!'
    }
  }
});

console.log(translate(ctx, 'greeting', { name: 'Alice' })); // Output: Hello, Alice!

Locale Management

This feature provides the ability to manage the current locale and fallback locales. The code sample demonstrates how to set and get the current locale and how to define a fallback locale.

const { createCoreContext } = require('@intlify/core-base');

const ctx = createCoreContext({
  locale: 'en',
  fallbackLocale: 'fr',
  messages: {
    en: {
      hello: 'Hello, world!'
    },
    fr: {
      hello: 'Bonjour, le monde!'
    }
  }
});

console.log(ctx.locale); // Output: en
ctx.locale = 'fr';
console.log(ctx.locale); // Output: fr
