hl7-date

Parse and stringify HL7 date format to native JS Date objects.

It only exports two methods: parse and stringify (just like JSON) and has zero dependencies.

HL7's date format is structured as follows, everything in [] is optional,

YYYY[MM[DD[HH[MM[SS[.S[S[S[S]]]]]]]]][+/-ZZZZ]

ZZZZ if present is in HHMM format

Install

$ npm i --save hl7-date

Examples

import HL7Date from 'hl7-date'

// precision is inferred based on precision of date
HL7Date.stringify(new Date(2010, 11, 3)) // 20101203

// precision can also be specifically passed
HL7Date.stringify(new Date(2010, 11, 3), 'year') // 2010

// parsing
HL7Date.parse('20101203231524.029-0800') // Date Object w/ value: 2010-12-04T07:15:24.029Z

available precision options for stringify

By default, precision will be determined by precision of date object given.

If a specific precision is required these are the available options:

'millisecond', 'second', 'minute', 'hour', 'date', 'month', 'year'
