Angular ui router parse query params into booleans

Question

Consider such scenario of a state with query parameters. I\'d like to have them declared as flags so I can fetch then in the controller and get true, fals

Answer 1

You should be able to use the bool as a type

url: '/foobar?{flag1:bool}&{flag2:bool}',

But we can even use our custom type (let's call it boolean):

app.config(['$urlMatcherFactoryProvider', function($urlMatcherFactory) {
  $urlMatcherFactory.type('boolean',
{
 name : 'boolean',
 decode: function(val) { return val == true ? true : val == "true" ? true : false },
 encode: function(val) { return val ? 1 : 0; },
 equals: function(a, b) { return this.is(a) && a === b; },
 is: function(val) { return [true,false,0,1].indexOf(val) >= 0 },
 pattern: /bool|true|0|1/
})
}]);

And the state def for url would be like this:

url: '/foobar?{flag1:boolean}&{flag2:boolean}',

and this should work:
