  • So once data has arrived, we can push those raw data values directly to our user interface for viewing to the user.
  • So it is clear from the above example, that some value requires an editing before getting viewed into the user interface.
  • Also, it can be noticed that the same type of transformation is required by us in many different user interfaces or vice versa.
  • So for this purpose, Angular 4 introduces Angular Pipes, a definite way to write display – value transformations that we can declare in our HTML.
  • In Angular 4.0, Pipes are classes implementing a single function interface, accepting an input value with an optional parameter array, returning a transformed value.

In this article, we will discuss about the pipes and view child concept in angular 4.0. When we want to develop any application, we always start the application with a simple basic common task i.e. retrieve data, transform data and then display the data in front of the user through our user interface. Retrieving data from any type of data source totally depends on thedata service provider like web services, web api etc.

When we want to develop an application, we always start the application with a simple basic common task i.e. retrieve data, transform data and then display those data in front of the user through our user interface. Retrieve data from any type of data source is totally depends on data service provider like web services, web API etc. So once data has arrived, we can push those raw data values directly to our user interface for viewing to the user. But sometimes, this does not happen exactly in the same manner. For example, in most use cases, users prefer to see a date in a simple format like 15/02/2017 rather than the raw string format Wed Feb 15, 2017, 00:00:00 GMT-0700 (Pacific Daylight Time). So it is clear from the above example, that some value requires an editing before getting viewed into the user interface. Also, it can be noticed that the same type of transformation is required by us in many different user interfaces or vice versa. So, in this scenario, we need to think about some style type property which we can be created centrally and applied whenever we require it globally. So for this purpose, Angular 4 introduces Angular Pipes, a definite way to write display – value transformations that we can declare in our HTML.
