How can I format a date string coming from the backend?












-2














I am using Reactjs and ES6 in the frontend. And GraphQL to make some API calls.
I am getting a key named createDate with a value like this:



2017-03-29T07:19:05-07:00



And I need to format it like this:



03/29/2017 07:19 AM it should show AM or PM.



As this is an string and I am not using any library, I expect someone could guide me to a solution...

You can convert the String to a date object first



var d = new Date("2015-03-25T12:00:00-06:30");


Then define a function constructs the string you want to use for representing the date. For example



function dateToString(d) {
var year = d.getFullYear();
var month = d.getMonth() + 1; // getMonth() returns 0-11
.
.
.
return year + "-" + month "-" + ...;


}

  • Using the built–in parser is not recommended due to quirks in various implementations, e.g. Safari incorrectly treats "2015-03-25T12:00:00" as UTC, not local.
