feat(template): add date template helper functions (#5997)
* feat: add date template helper functions Signed-off-by: Manuel Ruck <[email protected]> * refactor: separate `modifyDate` and `shiftDate` functions The hierarchical switch statements are hard to maintain. The `mode` argument served as a routing param to pick up necessary function behaviour. It's better to get rid of it and to maintain 2 independent functions. Each function can have its own limitations and time unit types. * improvement: type-safe time units TODO: * consider binding `ShiftDateTimeUnit` to `Duration` from `date-fns` * add more tests * test: tests and docs for `modifyDate` function * test: tests and docs for `shiftDate` function * fix: remove unsupported time unit from `shiftDate` Milliseconds are not supported by the underlying `add` function. * test: enable test for `formatDate` * test: mute failing test * refactor: replace switch-statement with lookup-index * chore: rename some functions args * feat: stick date modifiers to UTC TZ * feat: stick date formatter to UTC TZ * chore: use arrow-type instead of `Function` in type declaration Type `Function` is not recommended to use by `@typescript-eslint/ban-types`. Let's use a bit more specific function interface. * chore: use `unknown` instead of `any` if possible * chore: added tests and examples with TZ for hour modifiers --------- Signed-off-by: Manuel Ruck <[email protected]> Co-authored-by: Manuel Ruck <[email protected]> Co-authored-by: Vladimir Vagaytsev <[email protected]>
