I'm working on a route
.state('mystate', {
url: '/{id}',
templateUrl: '/views/partial.html'
});The id parameter needs to be in the form of a GUID like "2a542f61-5fff-4607-845d-972e6c3ad1e4". How can I include this format in the URL "url: '/{id:?what should i put here}'".
If you want to create a custom parameter type, you can do so by defining it yourself.
var GUID_REGEXP = /^[a-f\d]{8}-([a-f\d]{4}-){3}[a-f\d]{12}$/i;
$urlMatcherFactoryProvider.type('guid', {
encode: angular.identity,
decode: angular.identity,
is: function(item) {
return GUID_REGEXP.test(item);
}
});
Check out this demo on Plunker showcasing this solution.
To use this custom type in your URL route expression:
.state('mystate', {
url: '/{id?guid}',
templateUrl: '/views/partial.html'
});
For more information, refer to the documentation page.

If you want to define a URL with regex, you can do so like this:
url: "/{id:(?:[a-fA-F0-9]{8}(?:-[a-fA-F0-9]{4}){3}-[a-fA-F0-9]{12})}",

Here's a brief snippet for reference:
'{' name ':' regexp|type '}'- curly placeholder with regexp or type name. If the regexp has curly braces, make sure they are matched or escaped.
After numerous attempts and experimentation, I finally devised the following solution:
$urlMatcherFactoryProvider.type('uuid', {
encode: angular.identity,
decode: angular.identity,
equals: function(x, y) { return x.toUpperCase() === y.toUpperCase(); },
is: function(value) {
// Local variable to prevent lastIndex issues
var UUID_REGEX = /^[a-f\d]{8}-(?:[a-f\d]{4}-){3}[a-f\d]{12}$/i;
return UUID_REGEX.test(value);
},
pattern: /[a-fA-F\d]{8}-(?:[a-fA-F\d]{4}-){3}[a-fA-F\d]{12}/
});
This implementation was inspired by @just-boris's suggestion. One significant modification is the addition of the pattern. Without this, it seems that incorrect UUIDs may not trigger the $urlRouterProvider.otherwise() function.
