I'm using the date
pipe to format my date, but I just can't get the exact format I want without a workaround. Am I understanding pipes wrongly or is just not possible?
//our root app component
import {Component} from 'angular2/core'
@Component({
selector: 'my-app',
providers: [],
template: `
<div>
<h2>Hello {{name}}</h2>
<h3>{{date | date: 'ddMMyyyy'}}, should be
{{date | date: 'dd'}}/{{date | date:'MM'}}/{{date | date: 'yyyy'}}</h3>
</div>
`,
directives: []
})
export class App {
constructor() {
this.name = 'Angular2'
this.date = new Date();
}
}
Pipe date format bug fixed in Angular 2.0.0-rc.2, this Pull Request.
Now we can do the conventional way:
{{valueDate | date: 'dd/MM/yyyy'}}
Examples:
Current Version:
Old Versions:
Import DatePipe from angular/common and then use the below code:
var datePipe = new DatePipe();
this.setDob = datePipe.transform(userdate, 'dd/MM/yyyy');
where userdate will be your date string. See if this helps.
Make note of the lowercase for date and year :
d- date
M- month
y-year
EDIT
You have to pass locale
string as an argument to DatePipe, in latest angular. I have tested in angular 4.x
For Example:
var datePipe = new DatePipe('en-US');
You can achieve this using by a simple custom pipe.
import { Pipe, PipeTransform } from '@angular/core';
import { DatePipe } from '@angular/common';
@Pipe({
name: 'dateFormatPipe',
})
export class dateFormatPipe implements PipeTransform {
transform(value: string) {
var datePipe = new DatePipe("en-US");
value = datePipe.transform(value, 'dd/MM/yyyy');
return value;
}
}
{{currentDate | dateFormatPipe }}
Advantage of using a custom pipe is that, if you want to update the date format in future, you can go and update your custom pipe and it will reflect every where.
I always use Moment.js when I need to use dates for any reason.
Try this:
import { Pipe, PipeTransform } from '@angular/core'
import * as moment from 'moment'
@Pipe({
name: 'formatDate'
})
export class DatePipe implements PipeTransform {
transform(date: any, args?: any): any {
let d = new Date(date)
return moment(d).format('DD/MM/YYYY')
}
}
And in the view:
<p>{{ date | formatDate }}</p>
I am using this Temporary Solution:
import {Pipe, PipeTransform} from "angular2/core";
import {DateFormatter} from 'angular2/src/facade/intl';
@Pipe({
name: 'dateFormat'
})
export class DateFormat implements PipeTransform {
transform(value: any, args: string[]): any {
if (value) {
var date = value instanceof Date ? value : new Date(value);
return DateFormatter.format(date, 'pt', 'dd/MM/yyyy');
}
}
}
The only thing that worked for me was inspired from here: https://stackoverflow.com/a/35527407/2310544
For pure dd/MM/yyyy, this worked for me, with angular 2 beta 16:
{{ myDate | date:'d'}}/{{ myDate | date:'MM'}}/{{ myDate | date:'y'}}
I think that it's because the locale is hardcoded into the DatePipe
. See this link:
And there is no way to update this locale by configuration right now.
If anyone looking with time and timezone, this is for you
{{data.ct | date :'dd-MMM-yy h:mm:ss a '}}
add z for time zone at the end of date and time format
{{data.ct | date :'dd-MMM-yy h:mm:ss a z'}}
Date pipes does not behave correctly in Angular 2 with Typescript for Safari browser on MacOS and iOS. I faced this issue recently. I had to use moment js here for resolving the issue. Mentioning what I have done in short...
Add momentjs npm package in your project.
Under xyz.component.html, (Note here that startDateTime is of data type string)
{{ convertDateToString(objectName.startDateTime) }}
- Under xyz.component.ts,
import * as moment from 'moment';
convertDateToString(dateToBeConverted: string) {
return moment(dateToBeConverted, "YYYY-MM-DD HH:mm:ss").format("DD-MMM-YYYY");
}
If anyone can looking to display date with time in AM or PM in angular 6 then this is for you.
{{date | date: 'dd/MM/yyyy hh:mm a'}}
Output
Pre-defined format options
Examples are given in en-US locale.
'short': equivalent to 'M/d/yy, h:mm a' (6/15/15, 9:03 AM).
'medium': equivalent to 'MMM d, y, h:mm:ss a' (Jun 15, 2015, 9:03:01 AM).
'long': equivalent to 'MMMM d, y, h:mm:ss a z' (June 15, 2015 at 9:03:01 AM GMT+1).
'full': equivalent to 'EEEE, MMMM d, y, h:mm:ss a zzzz' (Monday, June 15, 2015 at 9:03:01 AM GMT+01:00).
'shortDate': equivalent to 'M/d/yy' (6/15/15).
'mediumDate': equivalent to 'MMM d, y' (Jun 15, 2015).
'longDate': equivalent to 'MMMM d, y' (June 15, 2015).
'fullDate': equivalent to 'EEEE, MMMM d, y' (Monday, June 15, 2015).
'shortTime': equivalent to 'h:mm a' (9:03 AM).
'mediumTime': equivalent to 'h:mm:ss a' (9:03:01 AM).
'longTime': equivalent to 'h:mm:ss a z' (9:03:01 AM GMT+1).
'fullTime': equivalent to 'h:mm:ss a zzzz' (9:03:01 AM GMT+01:00).
You can also use momentjs for this sort of things. Momentjs is best at parse, validate, manipulate, and display dates in JavaScript.
I used this pipe from Urish, which works fine for me:
https://github.com/urish/angular2-moment/blob/master/src/DateFormatPipe.ts
In the args parameter you can put your date format like: "dd/mm/yyyy"
You can find more information about the date pipe here, such as formats.
If you want to use it in your component, you can simply do
pipe = new DatePipe('en-US'); // Use your own locale
Now, you can simply use its transform method, which will be
const now = Date.now();
const myFormattedDate = this.pipe.transform(now, 'short');
