Cast int to enum strings in Typescript

Question

I get from a RESTful Service the following data:

[
  {
    \"id\": 42,
    \"type\": 0,
    \"name\": \"Piety was here\",
    \"description\": \"Bacon is tas         


        

Answer 1

Enums in TypeScript are numbers at runtime, so message.type will be 0, 1, 2 or 3.

To get the string value, you need to pass that number into the enum as an index:

Type[0] // "Info"

So, in your example, you'll need to do this:

Type[message.type] // "Info" when message.type is 0
