@lingui/message-utils

What is @lingui/message-utils?

@lingui/message-utils is a utility package for handling message formatting and manipulation in internationalization (i18n) contexts. It provides tools for parsing, formatting, and managing messages, making it easier to work with translations and localized content.

What are @lingui/message-utils's main functionalities?

Message Parsing

This feature allows you to parse a message string into an abstract syntax tree (AST). The parsed message can then be manipulated or analyzed programmatically.

const { parse } = require('@lingui/message-utils');
const message = 'Hello, {name}!';
const parsedMessage = parse(message);
console.log(parsedMessage);

Message Formatting

This feature allows you to format a message string by replacing placeholders with actual values. It is useful for generating localized content dynamically.

const { format } = require('@lingui/message-utils');
const message = 'Hello, {name}!';
const values = { name: 'John' };
const formattedMessage = format(message, values);
console.log(formattedMessage);

Message Validation

This feature allows you to validate a message string to ensure it conforms to the expected format. It helps in catching errors in message templates early.

const { validate } = require('@lingui/message-utils');
const message = 'Hello, {name}!';
const isValid = validate(message);
console.log(isValid);
