type

Response: Type.

Provides the type of response expressed by this object. Available options:

• basic: Normal, same origin response, with all headers exposed except "Set-Cookie".

• cors: Response was received from a valid cross-origin request. Certain headers and the body may be accessed.

• error: Network error. No useful information describing the error is available. The Response's status is 0, headers are empty and immutable. This is the type for a Response obtained from Response.error().

• opaque: Response for "no-cors" request to cross-origin resource. Severely restricted.

• opaqueredirect: The fetch request was made with redirect: "manual". The Response's status is 0, headers are empty, body is null and trailer is empty.

From MDN: "The type read-only property of the Response interface contains the type of the response."
