Usage Examples

Date Conversion

import { fromApiDate, toApiDate } from "@leancodepl/api-date-dayjs"
import dayjs from "dayjs"

const apiDate = "2023-12-25"
const dayjsDate = fromApiDate(apiDate)
console.log(dayjsDate.format("YYYY-MM-DD")) // '2023-12-25'

const convertedBack = toApiDate(dayjsDate)
console.log(convertedBack) // '2023-12-25'

Time Conversion

import { fromApiTime, toApiTime } from "@leancodepl/api-date-dayjs"

const apiTime = "14:30:00"
const dayjsTime = fromApiTime(apiTime)
const convertedBack = toApiTime(dayjsTime)
console.log(convertedBack) // '14:30:00'

DateTime with Offset

import { fromApiDateTimeOffset, toApiDateTimeOffset } from "@leancodepl/api-date-dayjs"

const apiDateTime = "2023-12-25T14:30:00+01:00"
const dayjsDateTime = fromApiDateTimeOffset(apiDateTime)
const convertedBack = toApiDateTimeOffset(dayjsDateTime)
console.log(convertedBack) // '2023-12-25T14:30:00+01:00'

Timezone Handling

import { dropLocalOffset } from "@leancodepl/api-date-dayjs"
import dayjs from "dayjs"

const localDate = dayjs("2023-12-25T14:30:00")
const utcDate = dropLocalOffset(localDate)
console.log(utcDate.format()) // Date without local offset
