Consider removing moment.js dependence as it's now considered as a legacy project

[Fcmam5]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

I believe that this has been reported many times, but now as Moment.js is considered as a legacy project in maintenance mode (see: https://momentjs.com/docs/#/-project-status/), in addition to the problems that we may face when working with it (bundle size, mutable APIs..)

What does the proposed API look like?

Switch to any date library.

ng-zorro-antd use date-fns

I recommend Day.js with antd-dayjs-webpack-plugin.

It's super easy to use and replace Moment.js is just one second. Every syntax and APIs are just exacetlly the same with nothing else to learn.

According to Moment.js's recommandation on their website:

Day.js is designed to be a minimalist replacement for Moment.js, using a similar API. It is not a drop-in replacement, but if you are used to using Moment's API and want to get moving quickly, consider using Day.js.

Day.js can be the first-class citizen in Antd, replacing all momentjs occurrence natively, instead of just being available as a plugin mentioned in #26759 (comment) . This also resolves issues like ant-design/antd-dayjs-webpack-plugin#23

It's a break change, maybe antd v5 ?

[zombieJ]

Yes. We have notice this. Since this will be a breaking change, we may not do action immediately in current version.

[xiaoxiangmoe]

dayjs and moment have the same API. They both have mutable API, which are easy to misuse.

Why not change to a new immutable library in this breaking change?

[zazzaz]

@xiaoxiangmoe Day.js is 2kB size and immutable, that's the main difference from moment.js.

Any information about what would not be backwards compatible using dayjs? It can be seen in #26807

[jeferson-sb]

any news on this one?

[masbaehr]

I was searching for a UI library, found ant-design, checked bundlephobia, and was shocked ;-)
Moment.js really should be replaced its a whopping 23% of the bundle size.

Luxon looks like the natural replacement of moment:

• It is authored by Isaac Cambron, a long-time contributor to Moment.
• It is the first recommendation in https://momentjs.com/docs/#/-project-status/.

@adisrael
Most alternatives are all looking pretty good, so it will take a small proof of concept to figure out which one is better.
Luxon is less popular, then date-fns, then dayjs in github stars (aka community love)
date-fns has most downloads, then it's dayjs then luxon
luxon also has less open issues (but smaller community, so who knows)
dayjs is the smallest in size and customizable to your needs
under the hood differences, etc

So there are definitely things to consider before making a choice. So far Ive used date-fns and dayjs with multiple lang support and perso I prefer dayjs, but yeah, that's my flavor because I tend to like smaller packages (queue explicit joke).
