How can I parse json to enum with typescript-CodePudding

I have a json string like this.

   {
     "type": "A",
     "desc": "AAA"
   }
or 
   { 
     "type": "B",
     "desc": "BBB"
   }
etc.

How can I use enum to parse it with typescript? I can do it like this, but how to handle with desc field?

enum Type {
   A = "A",
   B = "B"
}

CodePudding user response：

You may try using a type. Something like this

type Item {
 type: "A" | "B";
 desc: string;
}

CodePudding user response：

If the properties are related, i.e. type fully defines the value of desc, you can create a union type like this:

type Item =
  { type: "A", desc: "AAA" } |
  { type: "B", desc: "BBB" };
