Some time ago, the momentJS team decided to move their library to maintenance mode, meaning that they are not going to push any new feature anymore. Only bug/security fixes.

My company tries to keep up with the latest technologies and avoid a maximum the tech depts, which is why they decided lately to move away from momentJS. I took care of this process, let me tell you how it went.

Choosing the right library

The first step was about picking the right library for us. Migrating from a date library to another is not an easy thing and we don’t want to do it again anytime soon.

By having a look, I could identify three libraries that could be interesting which are:

• Date-fns
• DayJS
• Luxon

Those three libraries are interesting for the following reasons:

• A decent amount of stars on Github
• A large enough community (Easier when looking for help on Stackoverflow)
• An active development
• Usage of modern JS
