Typescript error: Undefined reference to 'DhImportKeyParams'

Question

Typescript error: Undefined reference to 'DhImportKeyParams'

Working on a project, I encountered an issue with a third-party library written in Typescript 3.7. The outdated library depended on the 'lib' that contained an interface called DhImportKeyParams. However, my current project uses Typescript 4.6 where this interface has been removed. As a result, when testing, I face the error "Cannot find name 'DhImportKeyParams'" due to the definition of the interface in the third-party library's ".d.ts" file:

export interface CryptoScheme {
    genAlg: Pbkdf2Params | AesKeyGenParams | HmacKeyGenParams;
    alg: string | RsaHashedImportParams | EcKeyImportParams | HmacImportParams | DhImportKeyParams | any;
    encrypt(key: CryptoKey, plaintext: string): PromiseLike<EncryptedObject>;
    decrypt(key: CryptoKey, obj: EncryptedObject): PromiseLike<string>;
}

I attempted to redefine DhImportKeyParams by creating a new interface in a separate file named typings.d.ts:

declare interface DhImportKeyParams extends Algorithm {
    generator: Uint8Array;
    prime: Uint8Array;
}

Even after adding the reference to this file in the tsconfig.json's typeRoots, the error persisted when running tests using tsconfig.spec.json. How can I properly define the missing interface so that Typescript can understand and compile the third-party library?

Answer №1

To ensure the interface declaration is globally accessible, you can do so by using the following code:

declare global {
  interface DhImportKeyParams extends Algorithm {
    generator: Uint8Array;
    prime: Uint8Array;
  }
}

If needed, you can include the following snippet at the end to indicate that the file should be treated as a module declaration by exporting something:

// Resolve the following error by making this a module declaration
//   Augmentations for the global scope can only be directly nested in external modules or ambient module declarations.(2669)
export type {};
