🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
The ambiguous-year guard silently does not apply to formats with non-numeric tokens or bracket literals.
hasAmbiguousYear maps every letter run to (\d{1,4}). Formats that contain non-numeric letter runs or escaped literals therefore never match inputPattern, and the function returns false at Line 131 without checking the year.
Two format shapes reachable from getDateFormat hit this:
datetime→'L - LT', which expands to e.g.MM/DD/YYYY - h:mm A. TheAtoken becomes(\d{1,4}), so01/24/2 - 3:45 PMnever matches the pattern.week→'[w] W GGGG'. The bracketed literalwand theWtoken both become(\d{1,4}), so no real input matches.
The comment at Lines 129-130 states that parseComplete's other checks reject such input. That is not the case for a short year: lenient parsing consumes YYYY/GGGG with any digit count, so charsLeftOver is 0 and unusedTokens is empty, and a single leftover digit commits as year 2 AD — exactly the case this guard exists to reject.
Restrict the digit substitution to numeric token runs, and treat bracketed literals as literal text.

- const formatParts = expandedFormat.match(/[a-zA-Z]+|[^a-zA-Z]+/g) || [];

- )
- .join('');

+ .join('');tokens at Line 134 must then use the same classification so the capture-group indexes stay aligned with the matched groups.
Add spec cases for getDateFormat('datetime') and getDateFormat('week') with a truncated year to lock this behavior.

watchValue also fires for the component's own emitted value, which defeats the raw-text preservation.
handleInputElementChange emits change for valid typed text and then sets rawInputValue = text. The comment at Lines 576-583 states the intent: keep the typed shorthand visible so a 2-digit year on its way to 4 digits is not rewritten.
In a controlled usage the consumer reacts to change by assigning value. That prop change triggers this watcher, which clears rawInputValue. The next render falls through to formatValue(this.value) and rewrites the field to the canonical text. The debounce case the comment describes is therefore not covered whenever the consumer is controlled, which is the documented usage in the examples.
Track whether the incoming value is the one this component just emitted, and skip the reset in that case.

Localize the default invalid-format message.
The fallback text at Line 367 is hardcoded English. This component already accepts language and now derives its format from that locale, so a Swedish or German user sees a localized pattern inside an English sentence.

setDateFormat cannot reset the format when the consumer clears format.
The guard skips falsy input. DatePickerCalendar.watchFormat calls this.picker?.setDateFormat(this.format), so clearing the format prop passes undefined and leaves this.dateFormat at the previous custom pattern.
DatePicker.updateInternalFormatAndType reacts differently: with no format, it sets internalFormat to the locale default. Flatpickr then parses typed text with the stale custom pattern while DatePicker validates the same text with the locale default. That is the same desync this method was added to remove.
The constructor needs the guard, because dateFormat has a subclass-provided default. An explicit update does not.
🐛 Proposed fix
public setDateFormat(dateFormat: string) {
- if (dateFormat) {
- this.dateFormat = dateFormat;
- }
+ // Deliberately unguarded, unlike the constructor: clearing the
+ // `format` prop must fall back to the same locale default that
+ // `DatePicker` starts validating typed text against, not keep the
+ // previous custom pattern.
+ this.dateFormat = dateFormat || this.getDefaultDateFormat();
}getDefaultDateFormat() needs to return the same pattern each subclass passes today, so the two sides agree.

I think a lot of the docstrings are overly expressive, we should probably shorten them and be more specific about what the function does if we want to keep them. Otherwise I see this becoming too chatty
Also I think we should address the code rabbit comments and sonarcloud findings (if neccessary)?

There are a few sonarcloud issues in this file, however I don't know if these are something we should act upon? Missing "key" prop for element in array this warning feels a bit off since we aren't really mapping anything in this array.

I feel that the current debounce set it quite short and I have multiple times when typing a year starting with 20 had to redo if I am not quick enough. Same goes for trying to erase the latter 20 from 2020 and it autoformatting the year

Review of the typed-input feature. Four issues I consider blocking (the value watcher rewriting text mid-typing, native clear regression, the ambiguous-year check being dead for most default formats, and the double change emit), plus three smaller ones inline.
| * of leftover invalid text. | ||

There was a problem hiding this comment.
Blocking: this rewrites the typed text mid-edit.
When the consumer echoes back the value that handleInputElementChange just emitted (as the new example does with onChange={e => this.value = e.detail}), this watcher clears rawInputValue. getDisplayValue is still in isEditing mode, so it falls through to formatValue(value) and writes the canonical text into the input.
Concrete case: type 1/24/20 on the way to 1/24/2023, pause past the input field's 300ms debounce. The debounced change parses 20 as 2020 (valid shorthand), emits, the consumer sets value, this watcher wipes rawInputValue, and the field becomes 01/24/2020 under the cursor. The next keystrokes give 01/24/202023. Deleting 20 from 2020 triggers the same loop.
The comment at line 576 describes exactly this scenario and says rawInputValue prevents it; this watcher undoes that. At minimum, don't clear rawInputValue while isEditing is true. Beyond that, committing on the debounce at all is questionable: a consumer that saves on change receives 2020 before the user finishes typing 2023. Consider only emitting on blur/Enter and using the debounced events for parseError feedback only.

Blocking: native inputs can no longer be cleared.
On main this was an unconditional this.change.emit(date), so clearing the native <input type="date"> on iOS/Android gave event.detail === '', parseDate returned null, and change(null) was emitted. This guard now swallows that case, so the consumer's value stays set and the field re-syncs to the old value. Once a value is set on mobile it can't be removed.
Emit null when the text is empty, same as clearValue does for the non-native path.

There was a problem hiding this comment.
Blocking: every typed commit emits change twice.
This emit fires from the input field's blur/Enter flush. Then Flatpickr's own allowInput blur/Enter handling sees the input text differs from getDateStr(), calls the patched setDate(text, true) (which passes the override since the text parses), which runs onValueUpdate -> handleClose -> handleCalendarChange -> a second change.emit with an equal Date.
Consumers doing work per change (API save, dirty tracking, undo stack) get duplicate entries. This also contradicts the new doc comment calling change the single source of truth. The root cause is two independent parsers bound to the same <input>; the cleaner fix is to stop giving Flatpickr the real input and push dates in only via setDate(Date), but at minimum the second emit needs to be suppressed.

The default invalid-format message is hardcoded English and ignores the language prop. A Swedish date picker shows Enter a valid date (YYYY-MM-DD) under an otherwise Swedish UI.
The sibling pickers already use translate.get(key, language) with keys from src/translations/*.ts, and the Translations class supports {param} substitution. Add a date-picker.invalid-format key with a {format} param to each bundle and use that here.

There was a problem hiding this comment.
Blocking: this check is dead for most default formats.
The pattern maps every letter run to (\d{1,4}) and treats [ / ] as literals, so any format containing a non-numeric token or a bracketed literal never matches, and the function returns false without checking anything. That includes the defaults for datetime (en: MM/DD/YYYY - h:mm A), week ([w] W GGGG) and quarter ([Q]Q YYYY).
Concrete cases:
- Default type, language
en: typing1/24/2 - 10:30 AMparses leniently as year 2 AD, parsing flags are clean, the pattern fails onAM, soparseCompletereturns a year-0002 date andchangeis emitted. type="week":w 5 20commits year 20 AD. The doc comment above says a 2-digitGGGGmust be rejected, but the guard never runs.
The tokenizer needs to handle A/a, bracketed literals, and ideally only build digit groups for the numeric tokens rather than every letter run.

There was a problem hiding this comment.
The L/l regex runs over bracket-escaped literals too, which moment itself never expands. format="[Deadline] L" is a valid moment format (renders Deadline 01/24/2026), but expandFormat turns it into [DeadM/D/YYYYine] MM/DD/YYYY, which is shown verbatim as the placeholder and in the invalid-format message, and also fed into hasAmbiguousYear.
Add \[[^\]]*\] as a first alternative in the regex and return those segments unchanged.
Separately: the if (!format) guard is unreachable from any internal caller (internalFormat is always a non-empty string after componentWillLoad). It only matters if an external caller passes undefined to the public parseDate. Either drop it or make the parameter optional so the signature is honest.

charsLeftOver > 0 rejects input with trailing or leading whitespace. Pasting 01/24/2026 (trailing space, common from copy/paste) leaves one char over, so parseComplete returns null and the field shows Enter a valid date (MM/DD/YYYY) even though the visible text matches the pattern. Flatpickr's own blur path uses trimEnd(), so the two parsers disagree on the same text.
Trim date before parsing, and before the hasAmbiguousYear regex.

Trim the input before you parse it.
A trailing space from a paste sets charsLeftOver > 0, so the code rejects a valid date. Flatpickr trims the same text on blur, so the two parsers disagree about it. Call date.trim() before moment(...) and before hasAmbiguousYear.

Ignore Enter during IME composition.
handleKeyDown blurs the input on every Enter. IME users (CJK) press Enter to confirm a composition candidate. That Enter blurs the field and commits partial text, and the parse error then shows while the user is still typing. Return early when event.isComposing is true or event.keyCode === 229.

Update handleKeyDown to return without blurring when the Enter event is part of
IME composition, checking event.isComposing or event.keyCode === 229. Preserve
the existing disabled, readonly, and non-Enter guards.

this.flatpickr.selectedDates is empty, before using selectedIndex, so clearing

Skip highlighting when no date is selected.
When Picker.setValue clears the value, Flatpickr empties selectedDates but retains selectedDateElem. This guard therefore accepts the previous $i, and the loop highlights a week although the value is empty. Check this.flatpickr.selectedDates.length before using the selected index.
