@iamkun I'm willing to get my hands dirty (not just complain). I have the translations ready for nl and pt-br so if I can PR those I'm game.

iamkun

@iamkun

OK . Nice job. I'll comment to that PR instead.

Hi guys. I am new to day.js, but it seems like it could be a good fit for me.
I am creating a library that other web-apps will be using. The most common use-case is for the library to be consumed via a script-tag in the browser, where they would then initialize the library.
I have two questions:

I want the end-users to be able to get the dates I use via day.js in their native language (when day.js supports it). But, I am worried about importing all locales before I build the script, as the resulting library would be way larger than ideal/necessary.
Since day.js doesn't support timezones, would I have to detect the users timezone and convert that to/from UTC (as the backend will always use UTC)

Ronny Hanssen

@Spiralis

I think I can perhaps load the locales dynamically from the CDN, perhaps? But, if my main library is loaded via npm, how can I then add dynamically loaded locales from CDN to the days instance? Is there an API for that?

iamkun

@iamkun

@Spiralis Day.js will use user's current timezone. But you can also use UTC plugin to force get UTC time.

Dynamic loading should be implemented in your js logic code not a Day.js feature.

Hello! I saw that there is a PR - iamkun/dayjs#375 - which is aimed towards enabling a "strict mode" when validating dayjs('812024', 'YYMMDD').isValid() === false. It's conflicting now, but are there plans to merge this in the future? Or is a different solution in the works?

iamkun

@iamkun

@bridzius I think a "strict mode " is important in some cases. We might could introduce this as a plugin to support both core dayjs as well as customParseFormat plugin.

@wesslim

Hi, it's possible to convert merely from minutes to hours and minutes?
eg. 90minutes convert to 1 hour 30 minutes

iamkun

@iamkun

@wesslim no at this time.

we could add a plugin to support this, and similar libs?

Anybody knows how to fix it? Thanks

Hi guys, dayjs how to format date to rfc3339 format ? like 2019-12-24T15:59:59Z

@dagda1

Hi all, is there anyway to have a strict mode.

import dayjs from 'dayjs';
import customParseFormat from 'dayjs/plugin/customParseFormat';

dayjs('2020-13-32', 'YYYY-MM-DD').isValid()  // wrong on both month and year

in fact

import dayjs from 'dayjs';
import customParseFormat from 'dayjs/plugin/customParseFormat';

dayjs('2020-99-78', 'YYYY-MM-DD').isValid()

I'm pretty sure I'm doing something very daft as the bottom one is about as invalid as can be

I am on dayjs@1.8.25

iamkun

@iamkun

@dagda1 Yes in next release iamkun/dayjs#882

iamkun

@iamkun

stirct mode released dayjs@1.8.26. @dagda1

Hey guys, I'm using dayjs and the plugin dayjs-business-days

I've added like this in my class. I'm using Angular.

import dayjs from 'dayjs';
import dayjsBusinessDays from 'dayjs-business-days';

export class Class {
  constructor() {
    dayjs.extend(dayjsBusinessDays);
  }

  add(fechaInicio: Date, dias: number): Date {
    return dayjs(fechaInicio)
      .businessDaysAdd(dias)
      .toDate();
  }
}

and I created a .d.ts file for it

import { Dayjs } from 'dayjs';

declare module 'dayjs' {
  interface Dayjs {
    businessDaysAdd(days: number);
  }
}

There's no linting issue, but when I run it I get

error TS2339: Property 'businessDaysAdd' does not exist on type 'Dayjs'

Is there something I'm missing?

iamkun

@iamkun

@ericmartinezr make sure the d.ts file you added is included in ts config
