is-fhir-date

Tiny module that determines if a given given string is a valid FHIR date type as per: https://www.hl7.org/fhir/datatypes.html#date and also checks it for validity.

The FHIR spec only specifies a regexp format, it does not check them for validity.

This module confirms both format and validity.

For example, the following will all pass the regexp but should not be considered valid because they're not valid dates:

'2021-02-29' // this is not a leap year
'2021-02-30' // february doesn't have 30 days
'2021-04-31' // april doesn't have 31 days

install

npm install is-fhir-date

usage

import isFhirDate from 'is-fhir-date'

isFhirDate('sept 29 82') // false
isFhirDate('1982') // true
isFhirDate('1982-12') // true
isFhirDate('1982-12-14') // true
isFhirDate('1998-02-30') // false
isFhirDate('2021-04-31') // false

test

npm test
