# ngx-moment
moment.js pipes for Angular
[](https://travis-ci.org/urish/ngx-moment)
[](https://www.npmjs.com/package/ngx-moment)
This module works with Angular 7.0.0 and newer.
For older Angular versions, please install [angular2-moment](https://npmjs.org/package/angular2-moment). For the AngularJS, please check out [angular-moment](https://github.com/urish/angular-moment).
Installation
------------
```bash
npm install --save moment ngx-moment
```
or if you use yarn:
```bash
yarn add moment ngx-moment
```
Usage
-----
Import `MomentModule` into your app's modules:
``` typescript
import { MomentModule } from 'ngx-moment';
@NgModule({
imports: [
MomentModule
]
})
```
If you would like to supply any `NgxMomentOptions` that will be made available to the pipes you can also use:
```typescript
import { MomentModule } from 'ngx-moment';
@NgModule({
imports: [
MomentModule.forRoot({
relativeTimeThresholdOptions: {
'm': 59
}
})
]
})
```
This makes all the `ngx-moment` pipes available for use in your app components.
Available pipes
---------------
## amTimeAgo pipe
Takes an optional `omitSuffix` argument that defaults to `false` and another optional `formatFn` function which can be used to customise the format of the time ago text.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{myDate | amTimeAgo}}
`
})
```
Prints `Last updated: a few seconds ago`
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{myDate | amTimeAgo:true}}
`
})
```
Prints `Last updated: a few seconds`
## amCalendar pipe
Takes optional `referenceTime` argument (defaults to now)
and `formats` argument that could be output formats object or callback function.
See [momentjs docs](http://momentjs.com/docs/#/displaying/calendar-time/) for details.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{myDate | amCalendar}}
`
})
```
Prints `Last updated: Today at 14:00` (default referenceTime is today by default)
``` typescript
@Component({
selector: 'app',
template: `
Last updated:
`
})
export class AppComponent {
nextDay: Date;
constructor() {
this.nextDay = new Date();
nextDay.setDate(nextDay.getDate() + 1);
}
}
```
Prints `Last updated: Yesterday at 14:00` (referenceTime is tomorrow)
``` typescript
@Component({
selector: 'app',
template: `
Last updated:
`
})
```
Prints `Last updated: Same Day at 2:00 PM`
## amDateFormat pipe
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{myDate | amDateFormat:'LL'}}
`
})
```
Prints `Last updated: January 24, 2016`
## amParse pipe
Parses a custom-formatted date into a moment object that can be used with the other pipes.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{'24/01/2014' | amParse:'DD/MM/YYYY' | amDateFormat:'LL'}}
`
})
```
Prints `Last updated: January 24, 2016`
The pipe can also accept an array of formats as parameter.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{'24/01/2014 22:00' | amParse: formats | amDateFormat:'LL'}}
`
})
export class App {
formats: string[] = ['DD/MM/YYYY HH:mm:ss', 'DD/MM/YYYY HH:mm'];
constructor() { }
}
```
Prints `Last updated: January 24, 2016`
## amLocal pipe
Converts UTC time to local time.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{mydate | amLocal | amDateFormat: 'YYYY-MM-DD HH:mm'}}
`
})
```
Prints `Last updated 2016-01-24 12:34`
## amLocale pipe
To be used with amDateFormat pipe in order to change locale.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{'2016-01-24 14:23:45' | amLocale:'en' | amDateFormat:'MMMM Do YYYY, h:mm:ss a'}}
`
})
```
Prints `Last updated: January 24th 2016, 2:23:45 pm`
Note: The locale might have to be imported (e.g. in the app module).
``` typescript
import 'moment/locale/de';
```
## amFromUnix pipe
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{ (1456263980 | amFromUnix) | amDateFormat:'hh:mmA'}}
`
})
```
Prints `Last updated: 01:46PM`
## amDuration pipe
``` typescript
@Component({
selector: 'app',
template: `
Uptime: {{ 365 | amDuration:'seconds' }}
`
})
```
Prints `Uptime: 6 minutes`
## amDifference pipe
``` typescript
@Component({
selector: 'app',
template: `
Expiration: {{nextDay | amDifference: today :'days' : true}} days
`
})
```
Prints `Expiration: 1 days`
## amAdd and amSubtract pipes
Use these pipes to perform date arithmetics. See [momentjs docs](http://momentjs.com/docs/#/manipulating/add/) for details.
``` typescript
@Component({
selector: 'app',
template: `
Expiration: {{'2017-03-17T16:55:00.000+01:00' | amAdd: 2 : 'hours' | amDateFormat: 'YYYY-MM-DD HH:mm'}}
`
})
```
Prints `Expiration: 2017-03-17 18:55`
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{'2017-03-17T16:55:00.000+01:00' | amSubtract: 5 : 'years' | amDateFormat: 'YYYY-MM-DD HH:mm'}}
`
})
```
Prints `Last updated: 2012-03-17 16:55`
## amFromUtc pipe
Parses the date as UTC and enables mode for subsequent moment operations (such as displaying the time in UTC). This can be combined with `amLocal` to display a UTC date in local time.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{ '2016-12-31T23:00:00.000-01:00' | amFromUtc | amDateFormat: 'YYYY-MM-DD' }}
`
})
```
Prints `Last updated: 2017-01-01`
It's also possible to specify a different format than the standard ISO8601.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{ '31/12/2016 23:00-01:00' | amFromUtc: 'DD/MM/YYYY HH:mmZZ' | amDateFormat: 'YYYY-MM-DD' }}
`
})
```
Or even an array of formats:
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{ '31/12/2016 23:00-01:00' | amFromUtc: formats | amDateFormat: 'YYYY-MM-DD' }}
`
})
export class App {
formats: string[] = ['DD/MM/YYYY HH:mm:ss', 'DD/MM/YYYY HH:mmZZ'];
constructor() { }
}
```
Both examples above will print `Last updated: 2017-01-01`
## amUtc pipe
Enables UTC mode for subsequent moment operations (such as displaying the time in UTC).
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{ '2016-12-31T23:00:00.000-01:00' | amUtc | amDateFormat: 'YYYY-MM-DD' }}
`
})
```
Prints `Last updated: 2017-01-01`
## amParseZone pipe
Parses a string but keeps the resulting Moment object in a fixed-offset timezone with the provided offset in the string.
``` typescript
@Component({
selector: 'app',
template: `
Last updated: {{ '2016-12-31T23:00:00.000-03:00' | amParseZone | amDateFormat: 'LLLL (Z)' }}
`
})
```
Prints `Last updated: Saturday, December 31, 2016 11:00 PM (-03:00)`
## amIsBefore and amIsAfter pipe
Check if a moment is before another moment. Supports limiting granularity to a unit other than milliseconds, pass the units as second parameter
```typescript
@Component({
selector: 'app',
template: `
Today is before tomorrow: {{ today | amIsBefore:tomorrow:'day' }}
`
})
```
Prints `Today is before tomorrow: true`
```typescript
@Component({
selector: 'app',
template: `
Tomorrow is after today: {{ tomorrow | amIsAfter:today:'day' }}
`
})
```
Prints `Tomorrow is after today: true`
NgxMomentOptions
----------------
An `NgxMomentOptions` object can be provided to the module using the `forRoot` convention and will provide options for the pipes to use with the `moment` instance, these options are detailed in the table below:
| prop | type | description |
| --- |:---:| --- |
| relativeTimeThresholdOptions | Dictionary
key: string
value: number | Provides the `relativeTimeThreshold` units allowing a pipe to set the `moment.relativeTimeThreshold` values.
The `key` is a unit defined as one of `ss`, `s`, `m`, `h`, `d`, `M`.
See [Relative Time Thresholds](https://momentjs.com/docs/#/customization/relative-time-threshold/) documentation for more details. |
Complete Example
----------------
``` typescript
import { NgModule, Component } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { MomentModule } from 'ngx-moment';
@Component({
selector: 'app',
template: `
Last updated: {{myDate | amTimeAgo}}, {{myDate | amCalendar}}, {{myDate | amDateFormat:'LL'}}
`
})
export class AppComponent {
myDate: Date;
constructor() {
this.myDate = new Date();
}
}
@NgModule({
imports: [
BrowserModule,
MomentModule
],
declarations: [ AppComponent ]
bootstrap: [ AppComponent ]
})
class AppModule {}
platformBrowserDynamic().bootstrapModule(AppModule);
