Converting Expression Output with Filters


When presenting data to the user, you might need to convert the data to a more user-friendly format. In our case we want to uppercase the name value from the previous recipe in the expression.


Use the uppercase Angular filter.

Enter your name: <input type="text" ng-model="name"></input>
<p>Hello {{name | uppercase }}!</p>


Angular uses the | (pipe) character to combine filters with variables in expressions. When evaluating the expression, the name variable is passed to the uppercase filter. This is similar to working with the Unix bash pipe symbol where an input can be transformed by another program. Also try the lowercase filter!
