There are few things missing in your filter. First of all you need to return new string. Secondary, regular expression is not correct, you should use global modifier in order to replace all space characters. Finally you also need to check if the string is defined, because initially model value can be undefined, so .replace on undefined will throw error.

All together:

app.filter('spaceless',function() {
    return function(input) {
        if (input) {
            return input.replace(/\s+/g, '-');    
        }
    }
});
