I'm trying out date-fns v2.
I want to format a date in a string by using the toDate
and format
functions:
import { format, toDate } from 'date-fns'
format(toDate('2019-02-11T14:00:00'), 'MM/dd/yyyy')
But get the following error:
RangeError: Invalid time value
It seems that you are using Version 2.0 of date-fns, which is still in alpha (development) status currently.
What functions are available and how they work still seems to change frequently. For example, while in version v2.0.0-alpha.26 toDate()
can handle string parameters, it cannot do that any longer in version v2.0.0-alpha.27. There is a new parseISO()
function instead.
This should work now:
format(parseISO('2019-02-11T14:00:00'), 'MM/dd/yyyy')
However, while version 2 is still in beta, I would suggest using the stable version 1.x for now.
date-fns 2.0.0-alpha.27 (demo: https://stackblitz.com/edit/js-tztuz6)
Use parseISO:
import { format, parseISO } from 'date-fns'
const formattedDate = format(parseISO('2019-02-11T14:00:00'), 'MM/dd/yyyy');
date-fns v1.30.1 (demo: https://stackblitz.com/edit/js-mt3y6p)
Use parse:
import { format, parse } from 'date-fns'
const formattedDate = format(parse('2019-02-11T14:00:00'), 'MM/DD/YYYY');
Btw, one more case to validate:
import { isValid, parseISO, parse } from 'date-fns'
// Date valid
if (isValid(parseISO('2019-11-27 09:45:00'))) {
let dt = parse('2019-11-27 09:45:00', 'yyyy-MM-dd HH:mm:ss', new Date())
}
The method toDate is not able to read that format.
Try to convert to Date lke this:
var date = new Date('2019-02-11T14:00:00')
