Formatting a Date String in React Native

Question

I'm trying to format a Date String in React Native.

Ex: 2016-01-04 10:34:23

Following is the code I'm using.

var date = new Date("2016-01-04 10:34:23");
console.log(date);

My problem is, when I'm emulating this on a iPhone 6S, it'll print Mon Jan 04 2016 10:34:23 GMT+0530 (IST) without any problem. But if I try with the iPhone 5S it prints nothing. And if you try to get the month by using a method like date.getMonth() it'll print "NaN".

Why is this? What is the workaround?

Answer 1

The beauty of the React Native is that it supports lots of JS libraries like Moment.js. Using moment.js would be a better/easier way to handle date/time instead coding from scratch

just run this in the terminal (yarn add moment also works if using React's built-in package manager):

npm install moment --save

And in your React Native js page:

import Moment from 'moment';

render(){
    Moment.locale('en');
    var dt = '2016-05-02T00:00:00';
    return(<View> {Moment(dt).format('d MMM')} </View>) //basically you can do all sorts of the formatting and others
}

You may check the moment.js official docs here https://momentjs.com/docs/
