Compile errors @aws-crypto/material-management with @types/node >= 16.0.2

Problem:

Cannot build Typescript project using @aws-crypto/material-management and @types/node >= 16.0.2

node_modules/@aws-crypto/material-management-node/build/main/src/material_helpers.d.ts:3:10 - error TS2724: '"crypto"' has no exported member named 'Signer'. Did you mean 'Sign'?

3 import { Signer, Verify, createCipheriv, createDecipheriv } from 'crypto';
           ~~~~~~

  node_modules/@types/node/crypto.d.ts:1265:11
    1265     class Sign extends stream.Writable {
                   ~~~~
    'Sign' is declared here.

Solution:

This issue is due to wrong type definition of crypto Sign class (previously Signer) fixed in DefinitelyTyped/DefinitelyTyped#54394
released with @types/[email protected]

Update @types/node to version 16.0.2 or higher
Rename Signer to Sign

This solution will be breaking change for developers using @types/node < 16.0.2

This can probably be closed then? :)

Seeing (what I think is the same error) using typescript 4.4.4 and the currrent latest version of the library 3.0.3 and node v14.18.1 / 16.12.0

npm install @aws-crypto/client-node@^3.0.3

index.js

import { NodeMaterialsManager } from '@aws-crypto/client-node'

tsc --noEmit --allowJS --checkJs index.js
 
node_modules/@aws-crypto/material-management-node/build/main/src/material_helpers.d.ts:3:10 - error TS2724: '"crypto"' has no exported member named 'Signer'. Did you mean 'Sign'?

3 import { Signer, Verify, createCipheriv, createDecipheriv } from 'crypto';
           ~~~~~~

  node_modules/@types/node/crypto.d.ts:1320:11
    1320     class Sign extends stream.Writable {
                   ~~~~
    'Sign' is declared here.


Found 1 error.

interesting/weirdly - installing (downgrading) to @types/node < 16.0.2 makes the problem go away

npm install @types/[email protected]

Howdy @sandfox , @tomasstrejcek , @cernytomas

The latest release of the ESDK-JavaScript supports Node 16.
If there are still problems with using our library with @types/node >= 16, please re-open or create a new issue.

Much Obliged,
