Explore Alternatives to Moment.js for Your Next JavaScript Project

Chapter 1: The Moment.js Legacy
Moment.js has long been a go-to library for handling dates in JavaScript projects. Despite its widespread use, recent statistics reveal that while it remains the most downloaded date library, alternatives like date-fns, day.js, luxon, and js-joda are gaining traction.
Many developers still depend on Moment.js for existing projects, and that's understandable. However, if you're starting a new project, it may be wise to explore some modern alternatives.
Section 1.1: The Shift from Moment.js
According to Moment.js's official announcement, the library is now considered a legacy project that is primarily in maintenance mode. While it's not obsolete, its development has effectively concluded. The team advises against using Moment.js for new projects, citing two significant issues:
- Mutability of Moment Objects: Moment.js objects are mutable, and changing them to be immutable would result in breaking changes, necessitating cloning for every modification.
- Size Concerns: Moment.js is a hefty 280.9 KB, and when including the timezone library, the size balloons to 467.6 KB. Unlike its alternatives, Moment.js does not support tree shaking, leading to unnecessary bloat for projects that only need specific features.
In one of my experiences at AWS, we only required the .format method from Moment.js. By eliminating it from our dependencies, we achieved a size reduction of over 500 KB, significantly enhancing our project performance.
Section 1.2: Exploring Alternatives
Now, let's delve into some of the modern alternatives to Moment.js.
Subsection 1.2.1: Day.js
Day.js is a lightweight JavaScript date utility library at just 2 KB. Its API is designed to be similar to Moment.js, allowing for easy chaining of date operations. Notably, Day.js promotes immutability by default and supports various plugins to enhance its core functionality.
Subsection 1.2.2: date-fns
date-fns offers a modern, modular approach to date manipulation in JavaScript. It features more than 200 functions, ensuring comprehensive support for various use cases. Each function is tree-shakable, making it easy to include only what you need, enhancing performance in bundled applications.
