Overriding filters in AngularJS and injecting dependencies into modules

My application relies on two filter modules:

 var app = angular.module('MyApp',['Filter1','Filter2']);

Both modules contain filters with the same name:

 var filterapp1 = angular.module('Filter1',[]);
 filterapp1.filter('replace',function(){return function(input){ 
             return input + " from Filter1 app";
 }});

 var filterapp2 = angular.module('Filter2',[]);
 filterapp2.filter('replace',function(){return function(input){ 
             return input + " from Filter2 app";
 }});

If I want to reference the filter from filterapplication1 in my application, how can I do that?

In my HTML, I have:

 {{'Hello World' | replace }} 

The expected output should be "Hello World from Filter1 app" but it is displaying "Hello World from Filter2 app". How can I override the filters? or do the filters override based on the order they are injected? How can I solve this issue?

Answer №1

Angular operates on a "last one wins" principle when it comes to filters. This means that if you intend to use multiple filters, they should be assigned distinct names. For instance, consider naming them as filter('module1.replace',....)
