Introduction to Pipes and Creating Interfaces
Explore how to enhance Angular applications by using pipes to format data at the view level and incorporate interfaces to define consistent data models. Learn practical steps to refactor components for improved type checking and application structure.
We'll cover the following...
Pipes allow us to transform the outcome of our expressions at the view level. They take data as input, transform it into the desired format, and display the output in the template.
The syntax of a pipe is pretty simple, consisting of the pipe name following the expression we want to transform, separated by a pipe symbol (|). Pipes are usually used with interpolation in Angular templates and can be chained to each other. Angular has a wide range of pipe types already built into it.
Before moving on to explore some of the built-in Angular pipes, we will make a change to our Angular working application to better demonstrate their use. The products array in the product list component is currently an array ...
