Converting TypeScript query string values into GUIDs

I'm currently working on a project that requires me to retrieve a string value (GUID) and convert it into a GUID.

The query string format is already in GUID, but when getting the value from the query string using AngularJS and TypeScript, it returns as a string.

How can I convert this string to a GUID?

URL:

https://localhost:44326/search?criteria=apparel&categoryId=c24dee00-ba9d-4af5-b357-a5b20033e5a7

TypeScript/Angular Code

export class Test
{
 categoryId: System.Guid;

init(): void {
     this.categoryId = this.queryString.get("categoryId");
   }
}

Upon executing the Init() function, an error occurs where the categoryId ends up empty without setting the query string value.

Answer №1

I have a current project where I need to retrieve a string value in GUID format and convert it into an actual GUID.

JavaScript / TypeScript does not have a built-in data type for GUIDs. It is recommended to represent them as strings instead.

Additional Information

If you want to keep track of all the GUIDs, you can define a custom type like this:

type GUID = string; 

You could also explore some nominal typing techniques by using nominal typing tricks.
