Change Log

This repo attempts to follow semantic versioning.

Unreleased

• None

1.5.0 FEATURE (2023/2/3)

Feature

• @rschedule/core Adds a metadata property to DateAdapterBase that can be used to store metadata related to a specific date adapter. Currently this property is just used by the ical-tools package to remember if a given DateAdapter should be serialized as a "date" or "date-time" value. Package consumers can also use this property to store data if they wish.

Fixes

• @rschedule/ical-tools fixes a bug which prevented the proper parsing and serializing of ical "date" values (e.g. "DTSTART;VALUE=DATE:20210909").

1.4.0 FEATURE (2022/6/9)

Feature

• @rschedule/ical-tools Add VEvent.fromJCal() static method. See #70 for additional information. I don't expect many people to benefit from this.

1.3.1 FIX (2021/11/9)

Fixes

• @rschedule/luxon-date-adapter fix typo in @rschedule/luxon-date-adapter/v1/setup and @rschedule/luxon-date-adapter/v2/setup package.json files

1.3.0 FEATURE (2021/10/3)

Feature

• @rschedule/luxon-date-adapter support both luxon v1.x and v2.x. If you want to use rSchedule with luxon v2, you can do so with the new v2 entrypoint in the @rschedule/luxon-date-adapter package.
  • e.g. import "@rschedule/luxon-date-adapter/v2/setup"

1.2.4 FIX (2021/1/12)

Fixes

• Ensure VEvent#set('start', ) also updates rrules/exrules (issue #56).

1.2.3 FIX (2020/11/19)

Fixes

• Standardize toISOString() implementation. Previously, different date adapters (apparently) were returning slightly different formatting (e.g. joda-date-adapter) (!62).
• Fix DatejsDateAdapter#set('timezone', value). Previously, attempting to set a new timezone value for a DayjsDateAdapter was ignored (!62).

1.2.2 FIX (2020/11/18)

Fixes

• Do not throw error when reregistering a JSON serializer (issue #53)

1.2.1 FIX (2020/9/25)

Fixes

• Explicitly define the return type of functions and methods (issue #47)

1.2.0 FEATURE (2020/6/25)

Feature

• Update typescript to version 3.9.x

Fixes

• Check presence of dayjs "UTC" plugin at run time rather than at import time (#44).

1.1.3 FEATURE (2020/6/16)

Feature

• Add DayjsDateAdapter package (#43).

1.0.5 FIX (2020/6/16)

Fixes

• Fixed the handling of the skipToDate OccurrenceIterator next() arg (!54)

1.0.4 FIX (2020/6/1)

Fixes

• Fixed an issue when using IntersectionOperator with a RecurrencePipe (!53)

1.0.3 FIX (2019/12/16)

Fixes

• Properly serialize a VEvent containing a rule with an interval (#39)
• Remove byMillisecondOfSecond from VEvent rule options.

1.0.2 FIX (2019/12/1)

• Same as 1.0.1 but fixes a build issue with that version.

1.0.1 FIX (2019/12/1)

Fixes

• Added all side effects declarations to each module's main package.json file as an attempted fix for issue #37. Previously each entry point handled it's own side effects declarations.

1.0.0 (2019/11/14)

• This marks the first non-beta release of rSchedule. There is no functional difference between this version and version 0.12.2.

0.12.2 FIX (2019/11/13)

Fixes

• Clarify the effect of the timezone argument in the docs.
• Fixed bug that could occur if a RecurrenceRulesIterator was passed run options with a start/end time in a different time zone from the RecurrenceRulesIterator's rule start time (#35).
• Fixed a bug that could result in generated date adapters not having the proper generators value.

0.12.1 FIX (2019/9/26)

Fixes

• Fixed module build targets so that UMD targets es5 and es2015 targets es2015 (#34)

0.12.0 BREAKING (2019/9/15)

This is a large breaking change to the library that simplifies the API and increases the modularity / extensibility of the code. You should check out the updated docs to understand all of the changes. The new API is similar to the old API, but better.

API improvements

Through some dark, typescript sorcery, rSchedule no longer needs to export generic objects to adapt the library's typing for different date adapters. Now you can simply import your date adapter of choice once, and the types of rSchedule's objects will automatically be updated. Where before you might have:

const rule = new Rule<typeof MomentDateAdapter>();

const dates: Moment[] = rule
  .occurrences()
  .toArray()
  .map(({ date }) => date);

// OR

const rule = new Rule<typeof StandardDateAdapter>();

const dates: Date[] = rule
  .occurrences()
  .toArray()
  .map(({ date }) => date);

now you simply have

const rule = new Rule();

const dates: Moment[] = rule
  .occurrences()
  .toArray()
  .map(({ date }) => date);

// OR, when using the StandardDateAdapter

const rule = new Rule();

const dates: Date[] = rule
  .occurrences()
  .toArray()
  .map(({ date }) => date);

it's magical! End users need never touch a date adapter.

Modularity changes

The @rschedule/rschedule package has been removed and replaced with @rschedule/core which itself has been broken up into @rschedule/core, @rschedule/core/generators, and @rschedule/core/rules. The recurrence rule API has also been improved, simplified, and now made public (where before it was private API).

• @rschedule/core contains the required bits of the library: the recurrence and date adapter logic and nothing else (it doesn't contain any actual recurrence rules).
• @rschedule/core/rules contains individual rule modules. You can now pick and choose which rules you care about, potentially reducing bundle size. Unused rules are tree-shakable. This also means that this library can add additional rules in the future, without worrying about bloating the library for folks that don't need the new features.
• Similarly, @rschedule/core/generators contains the opinionated OccurrenceGenerator API, which is also now optional and tree-shakable. This allows additional occurrence stream operators to be added in the future, without fear of bloating the library for folks who don't need them.

Breaking

Note: this update is large and not all changes are included below.

• @rschedule/rschedule -> @rschedule/core, @rschedule/core/generators, and @rschedule/core/rules.
• DateAdapter updated to support different date libraries via typescript declaration merging. This affects almost all of the types in the library, most of which are no longer generic.
  • OccurrenceGenerator is no longer generic. Similarly, Calendar, Schedule, Rule, and Dates only receive an optional generic param for their data attribute.
  • IDateAdapter removed and folded into the DateAdapterBase class. Now, all date adapters must extend the abstract DateAdapterBase class.
  • DateAdapter class renamed DateAdapterBase. DateAdapter is now an exported type equal to the activated date adapter, as well as a namespace.
  • It is now impossible to utilize two different date adapters in a single project at the same time. This was never encouraged, but previously it was possible.
• Dates duration constructor argument now only applies the duration to provided dates which do not already have a duration. Put another way, the duration option for the dates constructor now acts as a default duration for provided dates, rather than the duration of all dates.
• DateAdapter#duration type changed from number | undefined to number. A duration of 0 is treated as no duration.
• OccurrenceGenerator#collections() arguments changed. Specifically, CollectionIterator ICollectionArgs interface changed.
  • incrementLinearly option removed
  • skipEmptyPeriods option added
  • granularity "INSTANTANIOUS" option removed. Use "MILLISECONDLY" instead (which does the same thing).
  • By default, OccurrenceGenerator#collections() now increments linearly. You can use skipEmptyPeriods: true to get the old default behavior.
• Default granularity for OccurrenceGenerator#collections() is now "YEARLY". This change was made to accomidate the other changes to CollectionIterator.
• @rschedule/json-tools no longer exports parseJSON() or serializeToJSON() functions. Instead, the library contains individual modules for each rSchedule object which, when imported, modify that rschedule object, adding toJSON() and static fromJSON() methods.
• @rschedule/ical-tools no longer exports parseICal() or serializeToICal() functions. Instead, VEvent now has VEvent#toICal() and VEvent.fromICal().

Features

• Added DateAdapter#set('duration', number) option for setting a date adapters duration.
• RecurrenceRuleIterator, as well as individual recurrence rules, are now public API.

Fixes

• Fixed potential bug when calling OccurrenceGenerator#collections() with granularity "MONTHLY" and a weekStart value.
• Fixed the return type of OccurrenceGenerator#[Symbol.iterator]

Peformance

• OccurrenceGenerator#firstDate and OccurrenceGenerator#lastDate now cache their value after the initial lazy evaluation.
• Combine time-related rule pipe logic into a base class to reduce bundle size

Releases

0.11.6 FEATURE (2019/8/18)

Features

• Rigorously assert that rule options are valid. Previously, the library assumed typescript would catch obvious type errors and wouldn't bother checking for them.
• Add JodaDateAdapter

Fixes

• Prevent VEvent objects from being initialized with a rule specifying a MILLISECONDLY frequency.

0.11.5 FEATURE (2019/7/19)

Features

• upgraded OccurrenceGenerator methods to be duration aware
  • occursBetween
  • occursOn
  • occursAfter
  • occursBefore
• add option to Calendar#set() to set Calendar#schedules

0.11.4 FIX (2019/7/19)

Features

• added ability to set rule frequency to 'MILLISECONDLY'

Fixes

• added unit tests for PipeController and fixed bugs discovered during this process
  • fixed bug that affected reverse iteration of rules with a count property
  • fixed bug that affected reverse iteration with an interval > 1
  • fixed DateTime#set() bug that could occur when setting months
• added individual tests for each rule pipe
• fixed a few bugs in the RevByDayOfWeek pipe

0.11.3 FIX (2019/7/17)

Fixes

• fixed iterating Dates in reverse with either the start/end arg
• fixed OccurrenceGenerator#occursBefore()
• fixed iterating occurrence operators in reverse
• added tests to help ensure a similar issue doesn't happen in the future.

0.11.2 FEATURE (2019/7/15)

Features

• added SplitDurationOperator.
• added VEvent#duration support
• ical-tools can parse/serialize VEVENTs with duration/dtend property.
• Dates#set() can be used to set all the duration values of the underlying dates.

Fixes

• fixed MergeDurationOperator#_run() not returning all relevant occurrences when provided a start or end arg.
• make the ordering of all ordered date arrays duration aware (for resolving order of otherwise identical dates).

0.11.1 FEATURE (2019/6/17)

Features

• added MergeDurationOperator.

Fixes

• fixed bug in the calculation of Operator#isInfinite.
• fixed bug in AddOperator#_run() and IntersectionOperator#_run() when iterating with reverse: true and a start / end time.

0.11.0 BREAKING (2019/5/4)

Breaking

• updated RScheduleConfig so that config options are namespaced.
• updated @rschedule/json-tools
  • So that IntersectionOperator#maxFailedIterations is serialized.
    • There is no longer the option to provide maxFailedIterations to parseJSON().
  • The serializeToJSON() interface has changed
  • The parseJSON() interface has changed to improve typing
• replace ConstructorReturnType with typescript builtin InstanceType
• reversed the order of the DateAdapter#generators property.
• changed the default type of DateAdapter#generators to unknown[]
• fixed type inference in some @rschedule/rule-tools methods which involved changing the type arguments.

Features

• added @rschedule/rule-tools package.
• ability to set all Rule#options via Rule#set().
• added IScheduleLike<T extends typeof DateAdapter> interface.
• added IDataContainer<D> interface
• added RScheduleConfig.Rule.defaultWeekStart config option.
• added Operator.isOperator()
• added support for serializing / parsing the data property to @rschedule/json-tools.
• when iterating through a Schedule, Calendar, VEvent, Dates, or Rule object, the generators property now receives some proper typing. This will make accessing the data property on occurrence generators easier.
• improved typing of many isInstance methods.
• added DateAdapterFor<O extends IOccurrenceGenerator>
• added DataFor<O extends IDataContainer>
• added DateAdapter#end
• ability to keep local time when calling IOccurrenceGenerator#set('timezone')

Fixes

• AddOperator.isAddOperator()
• SubtractOperator.isSubtractOperator()
• IntersectionOperator.isIntersectionOperator()
• UniqueOperator.isUniqueOperator()
• OccurrenceStream.isOccurrenceStream()
• ensure DateAdapter#date is immutable
• don't include undefined properties in DateAdapter#toJSON()
• ensure DateAdapter#generators is propogated to results

0.10.0 BREAKING (2019/4/15)

Breaking

• fixed VEvent to allow multiple rrules / exrules as per the ical spec.
  • This also included appropriate changes in ical-tools serializeToICal() and parseICal() functions.
• updated Dates to not change the timezone associated with Dates#adapters. This means that a date in Dates#adapters may not have the same timezone as Dates#timezone (dates yielded by Dates are still updated to have the same timezone as Dates#timezone, however). This distinction can be important when serializing a Dates object as it ensures the original timezones associated with the underlying dates are preserved.

Features

• added ability to set individual Rule#options via Rule#set().
• added ability to pass whole Rule and Dates objects to the VEvent constructor.
• added VEvent#set(), VEvent#add(), and VEvent#remove().

0.9.1 FIX (2019/4/14)

Fixes

• Fixed npm tag associated with @rschedule/rschedule release

0.9.0 BREAKING (2019/4/14)

Breaking

• Rewrote repo so that, internally, immutable custom DateTime objects are used for datetime manipulation. This appears to have eliminated all outstanding recurrence bugs.
• Moved MomentTZDateAdapter into its own package.
• Updated json-tools to work with new API.
• Updated ical-tools to work with new API.
  • Added new VEvent object which aligns to the VEVENT component in the ICalendar spec.
  • Removed the ical-tools dependency on lodash.clonedeep.
• Eliminated EXRule, RRule, EXDate, and RDate objects. Now there are just Dates and Rule objects.
• Simplified the code for operators.
• Simplified the code for DateAdapters.
• Renamed until rule option to end.
• Changed rSchedule's representation of the "local" timezone from undefined to null.

Features

• Added in beginning of duration support.
• Migrated docs from a gitlab WIKI to individual files inside the repo so that doc changes are tracked alongside the repo.
• Added immutable add(), remove(), and set() CRUD methods to Schedule and Dates.
• Added immutable filter() method to Dates which filters the Dates object's associated dates and returns a new Dates object.
