What am I doing wrong (lots of typescript errors)

[john-charles]

Hello, I'm trying to use undici in my nodejs/typescript project and I'm getting a wall of typescript errors within the module.

Node version: v16.11.1
NPM version 8.0.0
TSC version 4.4.4

Typescript Config:

{
  "compilerOptions": {
    "lib": ["ES2020"],
    "module": "commonjs",
    "target": "ES2020",
    "outDir": "./.build",
    "sourceMap": true
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "**/*.spec.ts"]
}

My code includes a simple import:

import { Client } from "undici";

This causes a whole set of typescript errors:

node_modules/undici/types/dispatcher.d.ts:5:10 - error TS2305: Module '"buffer"' has no exported member 'Blob'.

5 import { Blob } from 'buffer'
           ~~~~

node_modules/undici/types/fetch.d.ts:5:10 - error TS2305: Module '"buffer"' has no exported member 'Blob'.

5 import { Blob } from 'buffer'
           ~~~~

node_modules/undici/types/fetch.d.ts:102:21 - error TS2304: Cannot find name 'AbortSignal'.

102   readonly signal?: AbortSignal
                        ~~~~~~~~~~~

node_modules/undici/types/fetch.d.ts:124:20 - error TS2304: Cannot find name 'AbortSignal'.

124   readonly signal: AbortSignal
                       ~~~~~~~~~~~

node_modules/undici/types/file.d.ts:4:10 - error TS2305: Module '"buffer"' has no exported member 'Blob'.

4 import { Blob, BlobOptions } from 'buffer'
           ~~~~

node_modules/undici/types/file.d.ts:4:16 - error TS2305: Module '"buffer"' has no exported member 'BlobOptions'.

4 import { Blob, BlobOptions } from 'buffer'
                 ~~~~~~~~~~~

What am I doing wrong? I'm not having issues with any other libraries and the project worked when I was using a different http client.

Any input would be appreciated!

What types are you using for Node.js?

@mcollina thanks, that was it, I was using an old version of @types/node
