5 alternatives to Moment.js for internationalizing dates

Formatting dates for international applications is essential, with Moment.js being a popular option among JavaScript libraries, although its size and structure have led developers to seek alternatives. The text reviews five alternatives for date internationalization: the JavaScript Internationalization API, Temporal API, Luxon, date-fns, and Day.js. The JavaScript Internationalization API provides constructors like Intl.DateTimeFormat and Intl.RelativeTimeFormat for language-sensitive date and time formatting. The Temporal API, still in proposal stages, offers a more robust way to handle dates and times, while Luxon improves on Moment.js by simplifying internationalization through a wrapper for Intl.DateTimeFormat and Intl.RelativeTimeFormat. date-fns is known for its functional programming approach, offering predictable behavior and excellent TypeScript integration, along with a related library, date-fns-tz, for strong timezone support. Day.js, a lightweight alternative to Moment.js, relies on plugins for advanced functionality, including relative time formatting. Additionally, little-date focuses on formatting date ranges and is built on top of date-fns. Each library offers distinct advantages, from bundle size and immutability to timezone support and ease of use, catering to different project needs and complexities.
