URL hash-bang (#!/) prefix instead of simple hash (#/) in Angular 1.6

My URLs on an AngularJS project have changed from localhost:3000/admin#/ to localhost:3000/admin#!/ since the last time I worked on my project...

Nothing found on the web, does someone know what this is ?

Solution 1:

It is new from AngularJS 1.6, which added a new hash prefix.

Due to aa077e8, the default hash-prefix used for $location hash-bang URLs has changed from the empty string ('') to the bang ('!'). If your application does not use HTML5 mode or is being run on browsers that do not support HTML5 mode, and you have not specified your own hash-prefix then client side URLs will now contain a ! prefix. For example, rather than mydomain.com/#/a/b/c the URL will become mydomain.com/#!/a/b/c.

If you want to remove this prefix, add this code to your config:

appModule.config(['$locationProvider', function($locationProvider) {
  $locationProvider.hashPrefix('');
}]);

Solution 2:

Everyone is proposing to remove the prefix, but you could also simply add a ! to client-side URLs (if not using HTML5 mode, which you probably do if you're here).

So in your client-side files, update URLS like this:

#/foo/bar > #!/foo/bar
