@intlify/message-compiler

What is @intlify/message-compiler?

@intlify/message-compiler is a powerful tool for compiling and formatting messages in internationalized applications. It is part of the Intlify project, which aims to provide comprehensive internationalization (i18n) solutions for JavaScript applications, particularly those built with Vue.js.

What are @intlify/message-compiler's main functionalities?

Message Compilation

This feature allows you to compile a message string with placeholders into a function that can be executed with a context object to produce a formatted message.

const { compile } = require('@intlify/message-compiler');
const msg = 'Hello, {name}!';
const compiled = compile(msg);
console.log(compiled({ name: 'World' })); // Output: Hello, World!

Custom Formatting

This feature supports custom formatting for numbers, dates, and other data types using the ICU MessageFormat syntax.

const { compile } = require('@intlify/message-compiler');
const msg = 'The price is {price, number, currency}.';
const compiled = compile(msg);
console.log(compiled({ price: 1234.56 })); // Output: The price is $1,234.56.

Pluralization

This feature allows you to handle pluralization in messages, making it easy to provide correct grammar for different quantities.

const { compile } = require('@intlify/message-compiler');
const msg = '{count, plural, one {# item} other {# items}}';
const compiled = compile(msg);
console.log(compiled({ count: 1 })); // Output: 1 item
console.log(compiled({ count: 5 })); // Output: 5 items

Other packages similar to @intlify/message-compiler

intl-messageformat

intl-messageformat is a package that provides similar functionality for formatting messages based on the ICU MessageFormat standard. It is widely used and supports complex message formatting, including pluralization and gender-specific messages. Compared to @intlify/message-compiler, intl-messageformat is more general-purpose and not specifically tied to the Vue.js ecosystem.

messageformat

messageformat is another package that implements the ICU MessageFormat standard. It offers a comprehensive solution for handling internationalized messages, including support for pluralization, gender, and select statements. Like intl-messageformat, it is not tied to any specific framework and can be used in various JavaScript environments.

react-intl

react-intl is a package specifically designed for internationalizing React applications. It provides components and APIs for formatting dates, numbers, and messages, as well as handling pluralization and other localization needs. While it offers similar message formatting capabilities, it is tailored for use with React, unlike @intlify/message-compiler, which is more general-purpose and Vue.js-oriented.
