The 'Server' type is not designed to be generic

Out of nowhere, I encountered the following error:

TypeScript: ./..\..\node_modules\@types\ws\index.d.ts:328:18
       Type 'Server' is not generic.

Answer №1

I encountered a similar problem and found that using 

npm i @types/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="acdbdfec9482998298">[email protected]</a>
resolved it for me.

Answer №2

My package.json had an outdated version of @types/node that didn't align with my current Node.js version.

To resolve this, I eliminated the specific dependency by running npm uninstall @types/node (allowing npm to handle it as a peer dependency).

Answer №3

It took me a couple of days to tackle updating and downgrading @types/node and @types/express. Finally, I successfully upgraded my angular project from version 14 to 15 with no issues.

Answer №4

We encountered a problem in the build pipeline of an Angular project that has been around for quite some time. Interestingly, it would fail every other build starting from June 2023. Fortunately, I was able to find a solution to resolve this issue. The approach I took was inspired by a suggestion made by Salmin Skenderovic in response to a post by Zen Donegan.

  1. To address the problem, I added the following dependency to packages.json:

    "@types/ws" : "<8.5.5",

The underlying assumption is that the bug lies within version 8.5.5 of @types/ws, hence we opt to use any version below 8.5.5 until the issue is resolved.

  1. Prior to compiling, it was necessary for me to execute the following command once:

    npm i --legacy-peer-deps

This command updates the package-lock.json file, effectively "locking in" all Angular dependencies for the project to a stable working configuration.

Answer №5

Upon facing this issue, I uncovered that the root cause was a glitch in my @types/node package. The error manifested when I was using version 17 of the package. Interestingly, every other major version I tested did not trigger the error.

It seems that the problem does not lie with the ws module as some have suggested, but rather with the compatibility between ws and certain iterations of @types/node.

Answer №6

After deleting the directory node_modules/@types/ws, my issue was resolved successfully. In the future, I plan to install packages using the command npm i --legacy-peer-deps.

Answer №7

I encountered a similar issue, but I also received the following notification: 

../node_modules/@types/node/globals.d.ts:72:13 - error TS2403: Subsequent variable declarations must have the same type. Variable 'AbortSignal' must be of type '{ new (): AbortSignal; prototype: AbortSignal; abort(reason?: any): AbortSignal; timeout(milliseconds: number): AbortSignal; }', but here has type '{ new (): AbortSignal; prototype: AbortSignal; }'.

To resolve this, I simply included two extra lines of code in the global.d.ts file for the AbortSignal variable, as instructed in the error message (there was already a TODO comment left by the developers):

declare var AbortSignal: {
    prototype: AbortSignal;
    new(): AbortSignal;
    // TODO: Add abort() static
    abort(reason?: any): AbortSignal; // <--------------lines which I added
    timeout(milliseconds: number): AbortSignal; //------|
};

After making these adjustments, the conversion to JS proceeded without any issues :)
