Update date-fns to v3 #265

christopherklint97 · 2023-12-28T07:49:51Z

Summary

This PR updates date-fns to v3 and adds support for it. Some other minor changes include:

Adding @babel/preset-env and removing the individual babel plugin transforms since they are included.
Running xit on the tests that expected a RangeError. This error does not seem to occur anymore in date-fns v3 but have chosen not to remove it in case these tests want to be rewritten.

We do not miss a loader, but we need to support https://babeljs.io/docs/babel-plugin-transform-logical-assignment-operators.

I understand that there are two options

explicitly use the plugin
use preset-env

Plugin

{
  "plugins": ["@babel/plugin-transform-logical-assignment-operators"]
}

@babel/preset-env

  "presets": [
    ["@babel/env", {
      "targets": ["2021"], // at least 2021
    }]

Here is a checklist for other changes we might need:

update peerDependencies to >=3.0.0 for date-fns (related to lock date-fns to 2.x #262)
Should .yarn/releases be committed? https://yarnpkg.com/getting-started/qa#which-files-should-be-gitignored

Nice, thanks for kick-starting this @christopherklint97 ! Doing an update without changing a lot of the inner-workings may be the quickest path forward.

Thanks everyone, I hope to find time for this soon.

Thanks for the reviews @antoinepairet @neilhem @JeromeFitz ! 🙌🏾

I got the tests to run now. Looks like 6 tests are failing at the moment, most are missing RangeErrors and some incorrect timezones.

@marnusw you probably know best here if we should keep the RangError checks and implement them in date-fns-tz or just remove them?

JeromeFitz · 2023-12-29T15:12:52Z

Thanks for making the time on the latest and greatest. Awesome, work @christopherklint97 !

For the RangeError ones date-fns@3 introduced types to inform the developer that they shouldn't do these things. So that may mean that intentionally breaking in a test will no longer work, since the errors themselves have changed. (I ran into these exact ones in an out-of-scope move to types.)

But would defer to someone who knows more on this package and karma for sure.

For this one though:

throws RangeError if options.firstWeekContainsDate is not convertable to 1, 2, ..., 7 or undefined

This changed to only allow 1 | 4 in date-fns@3 (in 2021):

Reference: https://github.com/date-fns/date-fns/blob/main/src/types.ts#L138

I believe this should also happen in date-fns-tz given the comments in date-fns code (reference in #2427). If so this would need to be changed in a few references:

Every index.js.flow would get their update in the next build per the current structure.

Though now that date-fns@3 exports types this could be changed further in typings.d.ts:

Some other slight changes with weekStartsOn|unit|roundingMethod should be confirmed if date-fns-tz has different values or should be kept in-sync.

import type { Day, FirstWeekContainsDate, LocaleUnit, RoundingMethod } from "date-fns";
import type { Locale } from 'date-fns'

type OptionsWithTZ = {
  weekStartsOn?: Day,
  firstWeekContainsDate?: FirstWeekContainsDate,
  additionalDigits?: 0 | 1 | 2,
  timeZone?: string,
  locale?: Locale,
  includeSeconds?: boolean,
  addSuffix?: boolean,
  unit?: LocaleUnit,
  roundingMethod?: RoundingMethod,
  awareOfUnicodeTokens?: boolean,
}

declare module.exports: (
  date: Date | string | number,
  timeZone: string,
  formatStr: string,
  options?: OptionsWithTZ
) => string

This is looking real good! Props again! 🎉

Additional Edit:

The Local date with specific non-location time zone error looks to be local on your machine. None of the Ci/CD have it, nor do I. (Who happens to be dateAndTimeZoneAmericaNY.)

Wonder if running:

env TZ=utc yarn run test

Would work locally?

But it is looking just like the RangeErrors:

SUMMARY:
✔ 261 tests completed
ℹ 1 test skipped
✖ 4 tests failed

A potential option if the tests should be kept in until date-fns-tz moves to types or something, their functions could be changed to xit which will tell karma to ignore the test.

package.json

JeromeFitz · 2023-12-29T21:42:24Z

Aye ... digging into this a bit more if the move to date-fns@3 types is to accompany.

The three places of change are:

1️⃣

./scripts/build/_lib/typings/formatBlock.js

L114:

"import type { Day, FirstWeekContainsDate, Locale, LocaleUnit, RoundingMethod } from 'date-fns'\n" +

2️⃣

./scripts/build/_lib/typings/typeScript.js

L296:

      import type { Day, FirstWeekContainsDate, Locale, LocaleUnit, RoundingMethod } from "date-fns"

3️⃣

./docs/OptionsWithTZ.js

Then editing the way they are currently formatted with flow

L9:

 * @property {Day} [weekStartsOn=0] - the index of the first day of the week (0 - Sunday).

L13:

 * @property {FirstWeekContainsDate} [firstWeekContainsDate=1] - the day of January,

L29:

 * @property {LocaleUnit} [unit] - used by `formatDistanceStrict`.

L31:

 * @property {RoundingMethod} [roundingMethod='floor'] - used by `formatDistanceStrict`.

Then after a yarn run build that will update the rest of the files accordingly. 😅

Suggested change

import { format as dateFnsFormat } from 'date-fns/format.js'

import { format as dateFnsFormat } from 'date-fns'

To avoid any further path change, maybe we should refer to global package ? It works and it's not path-specific, so more secure (imho).

Thought about this as well, but when I try to do this then I get errors.. 🤔

The version of date-fns we're using is v2.3, and it's been upgraded to v3 with breaking changes. I've pinned the current version we are using at v2.3 until this gets merged marnusw/date-fns-tz#265

christopherklint97 · 2024-01-08T08:17:09Z

@marnusw all tests are passing now since I am xiting the RangeError tests. All you have to do is merge and release a new version if you are happy 😉

@JeromeFitz I really appreciate the comments here and making it so easy for me to copy and paste the changes 👍🏾

gehringf · 2024-01-08T10:48:29Z

Looking forward to this 😃

yarn.lock

Nearly 2k lines added here which is maybe disproportionate to the packages added? Did you run yarn dedupe?

Yes I ran yarn dedupe but it did not change anything unfortunately.

.yarn/releases/yarn-3.6.4.cjs adds around 900 lines, so roughly half. Guess that's not too bad..

@keesvanbemmel if you really can't wait you can npm install from any github repo or branch, including the branch for this PR (christopherklint97:update-to-v3).

I tried your fork on my ESM project and this import fails because it is not exported by date-fns

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './_lib/getTimezoneOffsetInMilliseconds.js' is not defined by "exports" in /../date-fns-tz/node_modules/date-fns/package.json imported from /../date-fns-tz/esm/toDate/index.js

I can patch date-fns to export it, but not sure what would be a better long term solution

@Cellule did you find a resolution for this? I have the same error.

BlindDespair · 2024-02-25T13:36:54Z

Can we have a release please? Installing from branch may be okay for development but launching a product to production with a dependency like that is not safe. I cannot start using this library because our project was started with date-fns v3 and downgrading is more effort than what it's worth. I get that maintainers may be busy people, but someone already put time and effort into making this PR while community keeps begging for this to be released.

tomalaforge · 2024-02-25T14:34:13Z

I know that maintaining a OSS is a lot of work. I'm maintaining one myself. But here, everything has been done. I don't understand what is stopping you from merging and publishing a new version. It should take 30min max. 🙏

stephenhmarsh · 2024-02-25T21:18:37Z

In defense of @marnusw this is a new major version with breaking changes and maybe he needs time to consider the implications and how to document. Besides the imports, several tests were turned off because they no longer throw expected errors. If you think installing from a branch is "not safe," publishing a major version without fully understanding the breaking changes is worse. There's literally a comment right above @BlindDespair with a bug.

You can always clone the PR branch to your own repo and lock your install to the exact commit SHA. That's really as safe as you can you can ask for, especially if you're so personally sure this code is 100% ready and @marnusw has no reason not to merge it.

BlindDespair · 2024-02-25T22:12:25Z

@stephenhmarsh that is so, but this package is linked by date-fns' documentation as go-to solution for working with timezones when using date-fns. Normally other libraries or frameworks update together around the same time, meaning date-fns-tz would take care of these changes before v3 was even released on the main package. Otherwise the date-fns package shouldn't link to this package and not claim that there's a way to work with timezones and maybe explicitly state that their package is not recommended if timezones are necessary.

SheldonWBM · 2024-02-26T15:41:00Z

"Patience is a virtue". Does v2 have any security implications, not yet. Is this being worked on for free, yes.

@marnusw anything pending for this PR to be merged? If possible release a beta

A beta can be official or, use this branch directly. See https://martinwolf.org/2018/04/github-branch-as-dependency-package-json/
Then you can help troubleshoot but, I would not use it for production.

marnusw · 2024-03-11T21:39:48Z

@christopherklint97 after merging some other PRs and upgrading to yearn 4.1.1 when I rebase your branch or merge master into it the tests fail on optional chaining errors from date-fns for some reason. When I just upgrade your branch to yarn 4.1.1 it still works fine though, so that doesn't seem like it can be the cause. I couldn't figure it out over the weekend but I'll take another look later this week. I just thought I'd post this for the record in case you or anyone else had some thoughts.

joacub · 2024-03-11T23:14:24Z

This pull is wrong still having many issues in imports

marnusw · 2024-03-18T14:48:17Z

3.0.0-beta.0 is available. There will be some minor breaking changes in the final release which I still need to get to (function name changes, bringing some aspects in line with the new date-fns way of doing things - nothing major), but at least you have this to install from npm now! Thanks again @christopherklint97.

Fouzyyyy · 2024-03-18T15:13:34Z

@marnusw is there a draft PR or so we could watch for the next release? Because currently we don't want to ship a library in beta version, we would rather stick to the v2 in the meantime.
