Switch from 'moment' to 'dayjs'

Almost exactly the same as d81ccee.
I changed the User.prototype.isOnline method to not use greater than and instead use the dayjs query isAfter.

• forum.js: 361 KB ----> 318 KB (-12%)
  • forum.js.map: 1.5 MB ----> 1.3 MB (-13%)
• admin.js: 280 KB ----> 240 KB (-14%)
  • admin.js.map: 1.2 MB ----> 956 KB (-26%)

Total bundle size reduction by 85 KB across forum & admin (excluding source maps).

moment will still mostly work, it now is the same as dayjs.

The only big breaking change I think is that moment.duration is no longer a thing.

In PostStream:

The moment config in language packs should continue functioning for the most part.

With no additional changes, Dutch language pack working just fine.

Looks like there is an official plugin for duration. Do we want/need this?

It'd add ~4 KB back.

Forum goes to 324 KB and admin remains the same.

Are we using duration?

[dsevillamartin]

@askvortsov1 We were for time lapsed in the post stream. Some other extensions use it as well. Not sure if we want it because it may have differences in some locales... the function I replaced it with in PostStream basically does the same thing as far as I can tell.

EDIT: I think we can ignore it. All it really adds is the moment-esque API I think. Its a very small file (https://github.com/iamkun/dayjs/blob/dev/src/plugin/duration/index.js). The whole thing basically boils down to dayjs().add(<time>, <measure>).fromNow().

Alright I'm fine not adding it then 👍

Make sure this get's added to the Beta.14 meta issue after merge

I've replaced moment with dayjs in the two bundled extensions (statistics, suspend) that used it. We should consider deprecating the moment alias for stable.
