v2.0.0

2.0.0

A breaking release. See MIGRATION.md for the upgrade guide.

Breaking

• ESM only. The CommonJS and UMD builds are gone; the package publishes a
  single ES module through an exports map. require('vue-event-creator') and
  <script> tag usage are no longer supported.
• The stylesheet moved to vue-event-creator/style.css. The v1 paths
  (dist/styles.css, which never existed, and dist/vue-event-creator.css) are
  not part of the public surface. Deep imports into dist are unsupported.
• Types are generated and published. The hand-written src/index.d.ts is
  replaced by declarations emitted from a typed entry. Callback and event types
  are generic over the consumer's data shape instead of Function/object/
  any. Internal state types are no longer exported.
• setI18n and setDayJsLang are removed. Locale is set through the
  language prop, which is now reactive and scoped to the instance.
• editEventFn receives the event being edited instead of being called with
  no arguments.
• editEventFn and removeEventFn report failure by rejecting. A resolved
  { error } value from those two callbacks is no longer treated as a failure;
  only saveEventFn accepts that shape.
• saveEventFn must return the dates it was given. A saved event whose
  dates differ from the submitted ones is reported as an error instead of being
  applied.
• Loaded events are validated. getEventsFn results containing an invalid
  date, an event finishing before it starts, or two events sharing a calendar
  date show the load error rather than rendering a partly wrong calendar.
• Event cards are keyed by data-vec-event-id, replacing the document-wide
  vec-es-id-<date> element id.
• Days and the responsive switcher are <button> elements, not clickable
  <div>s. All buttons declare type="button".
• Node.js 24.0 or newer is required for tooling, and Vue ^3.x is the
  declared peer range. Node 22 is not supported.

Fixed

• An event id of 0 is treated as a saved id instead of an unsaved draft.
• Two calendars mounted at once no longer share a locale, steal each other's
  focus, or scroll each other's event cards.
• firstDate and monthsOnPage changes rebuild the calendar; defaultTime and
  language changes apply without a remount.
• Failed loads show a retry alert instead of leaving the loader spinning; save,
  edit, and remove failures are shown on the card instead of only being logged.
• A callback in flight is no longer invoked twice for one user action.
• Document click listeners are registered through a lifecycle-aware composable
  and removed on unmount.
• Consumer-supplied events and data objects are never mutated.

Added

• MIGRATION.md, a rewritten README.md, and documented Node/browser support,
  time-zone semantics, overlap constraints, and the release process.
• Keyboard operation of the calendar, with accessible names and states on days,
  the switcher, and the time inputs.
• A release pipeline: pull-request CI, a tag-driven release workflow publishing
  with npm provenance, scheduled Firefox/WebKit E2E runs, and a
  release:check gate that also runs from prepublishOnly.
• Playwright E2E journeys against both the demo app and the packed package.

Changed

• Rebuilt on Vite 8, Vitest 5 (Node and Chromium browser projects), oxlint, and
  oxfmt. ESLint and Prettier are removed.
