atma-formatter

A utility library for formatting dates, numbers, and strings with localization support. Current version 0.8.15 provides pattern-based formatting for dates (e.g., yyyy-MM-dd), numbers (e.g., ,0.00), and strings (with alignment and pluralization). It works both in Node.js and browser environments. Key differentiators include integration with MaskJS template engine, culture/language support for internationalization, and a unified API for multiple formatting tasks. Compatible with CommonJS and global browser usage. Last updated several years ago and shows low maintenance cadence.
