TypeScript cannot find node module with index.d.ts

Question

I'm trying to use EventEmmiter3 with the following syntax:

import EventEmitter from 'eventemitter3'

I have this module installed under the ./node_modules folder. This module contains a index.d.ts so I think it should be detected by Typescript. But instead get the error:

[ts] Cannot find module 'eventemitter3'.

I tried adding ./node_modules to the included types in my tsconfig.json without success:

{
  "compilerOptions": {
    "typeRoots": ["./node_modules", "./node_modules/@types"]
  }
}

How should I configure Typescript to find node modules?

EventEmitter has no default exporter, try to import using import * as EventEmitter from 'eventemitter3' — rpadovani

@rpadovani I ran into this issue as well. With your code I couldn't extend the EventEmitter class which I think is strange.. Though this works: import {EventEmitter} from 'eventemitter3'. I guess it's really just a case by case solution. Thank you! — Yovar

I solved it by adding the following in my tsconfig.json:

{
  "compilerOptions": {
    "moduleResolution": "Node"
  }
}

The reason for this is the fact that for target: es6 and higher TypeScript by default uses module: ES6 and therefore moduleResolution: Classic: typescriptlang.org/docs/handbook/compiler-options.html And classic module resolution doesn't work with node_modules.

For ECMAScript that use import statement, set the moduleResolution to 'nodenext' instead

{
  "compilerOptions": {
    "moduleResolution": "nodenext"   // or 'node16'
  }
}
