@yanshoof/types

Global, organization-scoped types and type guards

Why this package

In order to reduce code splitting across our platforms, we created a package that can be used to declare types.

The Type Library

Date and Time

• type DayOfWeek: a number from 0 to 6 inclusive
• type HourOfDay: a timetable hour, ranging from 0 to 12 inclusive
• const DAYS_IN_WEEK: 7
• const HOURS_OF_DAY: 13

Classrooms

• interface IClassLookup represents a class lookup object

School Search

• interface ISchoolLookupResult respresents a school lookup result

Lessons and Changes

• enum LessonModification is a modification that can be done to a lesson: cancellation, change of teacher, change of classroom, etc.
• interface IModification is a combination of an optional modification and optional data
• interface IStudyGroup is a combination of a teacher and a subject
• function isStudyGroup is a type guard for the study group interface
• interface IStudyGroupWithModification extends IStudyGroup, IModification represents a modification. Determines a study group and the exact modification to it.
• interface ILesson extends IStudyGroup represents a changeable lesson and is the standard lesson type across all plafroms
• type LessonOrMultiple represents multiple lessons taking place at the same time
• function isILessonObj is a type guard for the ILesson interface
• function isAnyLessonObj is a less strict type guard for multiple types of lessons
• type ITeacherLesson is a lesson whose teacher is known in advance
• interface IChange extends IStudyGroupWithModification is a change in the schedule, the standard across all platforms.

Timetables

• interface ITimetable<TLesson, TSchedule> represents a timetable that is built from a schedule of another type
