chore(deps): bump date-fns from 3.6.0 to 4.1.0

[dependabot[bot]]

Bumps date-fns from 3.6.0 to 4.1.0.

Release notes

Sourced from date-fns's releases.

v4.1.0

This release adds time zone support to format functions (that I somehow missed when working on the feature) and fixes a few bugs.

Make sure also upgrade TZDate to v1.0.2 as it includes a bunch of critical bug fixes.

Fixed

• Fixed internal constructFrom throwing an exception on null arguments. While null isn't allowed, the functions should rather return Invalid Date or NaN in such cases. See #3885.

Added

• Added missing time zone support to format, formatISO, formatISO9075, formatRelative and formatRFC3339. See #3886.

v4.0.0

I have great news! First, ten years after its release, date-fns finally gets first-class time zone support.

Another great news is that there aren't many breaking changes in this release. All of them are type-related and will affect only those explicitly using internal date-fns types. Finally, it has been less than a year since the last major release, which is an improvement over the previous four years between v2 and v3. I plan on keeping the pace and minimizing breaking changes moving forward.

Read more about the release in the announcement blog post.

Added

• Added time zones support via @date-fns/tz's TZDate class and tz helper function. See its README for the details about the API.

• All relevant functions now accept the context in option, which allows to specify the time zone to make the calculations in. If the function also returns a date, it will be in the specified time zone:

  import { addDays, startOfDay } from "date-fns";
  import { tz } from "@date-fns/tz";
  startOfDay(addDays(Date.now(), 5, { in: tz("Asia/Singapore") }));
  
  //=> "2024-09-16T00:00:00.000+08:00"
  
  

  In the example, addDays will get the current date and time in Singapore and add 5 days to it. startOfDay will inherit the date type and return the start of the day in Singapore.

Changed

• The function arguments, as well as Interval's start and end, now can be of different types, allowing you to mix UTCDate, TZDate, Date, and other extensions, as well as primitives (strings and numbers).

  The functions will normalize these values, make calculations, and return the result in the same type, preventing any bugs caused by the discrepancy. If passed, the type will be inferred from the context in option or the first encountered argument object type. The Interval's start and end will be considered separately, starting from start.

  In the given example, the result will be in the TZDate as the first argument is a number, and the start takes precedence over the end.

  clamp(Date.now(), {
    start: new TZDate(start, "Asia/Singapore"),
    end: new UTCDate(),

Would be great to have this merged, or just change the version in package.json to "^3.6.0 || ^4.1.0". There are pretty much no breaking changes in v4 and after the upgrade in my app I have both versions bundled.

[martijnrusschen]

@balajis-qb Another interesting challenge. This should be pretty simple, but the docs site broke after upgrading the package to V4.

[balajis-qb]

@martijnrusschen, Sure, I'll check.

[balajis-qb]

@martijnrusschen , We are facing an issue as [email protected] defaults to ES Module

In our Rollup js config we marked date-fns and it's sub-packages as external dependencies - it'll skip the date-fns code being added to our generated bundle. It'll be dynamically imported by the browser. But as browser can't natively handle ESM moduls it's breaking. Previously it worked as in v3.6 date-fns didn't use ESM module.

One simple solution is to add date-fns to our bundle, by removing it from external config of rollup.config

[martijnrusschen]

Gotcha, I think the tricky part is that including it will increase the bundle size pretty heavily.

[paolostyle]

Isn't that a problem with the website, not with the library? Presumably the dependencies are eventually bundled, so it's a responsibility of the end user to process them if necessary. Also ESM should actually work in a browser without any transpilation, as long as the <script> tag has type="module" attribute.

[martijnrusschen]

Here's a reference to the previous issue which introduced this logic: https://github.com/Hacker0x01/react-datepicker/issues/1606. If we can get this upgrade in without drastically increasing the bundle size, that would be great.

@dependabot rebase

[dependabot[bot]]

Looks like this PR has been edited by someone other than Dependabot. That means Dependabot can't rebase it - sorry!

If you're happy for Dependabot to recreate it from scratch, overwriting any edits, you can request @dependabot recreate.

[dependabot[bot]]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
