Configuration Check

My config is the default config created by running npm init -y && npx tsc --init. No packages have been installed.

NPM Version: 9.6.2

Missing / Incorrect Definition

The Blob type defined here https://github.com/microsoft/TypeScript/blob/e83d61398ea0e4231e882121dd6c6bcfe4fdc9e4/src/lib/dom.generated.d.ts#L3075 is not assignable to the Blob type in node here https://github.com/DefinitelyTyped/DefinitelyTyped/blob/ec8923e261d3619aef6a4663d50159e7e0dcf3e9/types/node/buffer.d.ts#L121 due to type applied to the prototype.

Sample Code

import { Blob as BufferBlob } from "buffer";
const bl: Blob = new BufferBlob([]);

Causes the typescript compilation error

Property 'prototype' is missing in type 'import("buffer").Blob' but required in type 'Blob'.ts(2741)
lib.dom.d.ts(2591, 5): 'prototype' is declared here.

The default config includes the DOM (i.e. web browser API) types; since you're targeting Node, you should install @types/node if you haven't already and then write a lib entry in your tsconfig that doesn't include dom. It is known that the DOM types are incompatible with @types/node.

It sounds like this is a problem in the node .d.ts, not the DOM's.

@RyanCavanaugh isn't this essentially the same as #52166?

In light of this response can this issue be re-opened and addressed as part of the 5.1.0 milestone along with #52166 and any other vars that may have the same regression.

@RyanCavanaugh can this issue please be re-opened per #53668 (comment)
