Date pipe default format and timezone

The date pipe is the most convenient way to format dates with Angular. However, very often, we need to use a consistent date format throughout our application, which means that we have to pass that custom format every time we use the date pipe:

<span>Today is {{today | date: 'MM/dd/yy'}}</span>Code language: HTML, XML (xml)

Of course, we could store that format in a constant and reuse that constant every time we use the pipe, but that’s not very convenient.

Luckily for us, since Angular 15, we can now set a default date format (and timezone) by configuring a new injection token called DATE_PIPE_DEFAULT_OPTIONS.

It works by adding the following code to your dependency injection config (array of providers) in app.modules.ts:

providers: [
  {
    provide: DATE_PIPE_DEFAULT_OPTIONS, useValue: {dateFormat: 'MM/dd/yy'}
  }
]Code language: JavaScript (javascript)

With such a config in place, we can use our pipe without any parameters and have our default formatting applied automatically in our entire application:

<span>Today is {{today | date}}</span>Code language: HTML, XML (xml)

The timezone can be customized as well with the timezone property of that same DatePipeConfig object.
