This dependency was not found: * worker_threads

Question

I previously tested and used worker_threads in my project.

Now when attempting to npm run serve or npm run build I'm getting the following error:

This dependency was not found:

• worker_threads

I am running node --version v14.17.2 so I know that worker_threads are supported.

I have even created a clean project with Vue CLI and when adding the following code, I still see the same error.

const {
  Worker, isMainThread, parentPort, workerData
} = require('worker_threads');

I've searched extensively, but all of the problems and solutions relate to earlier versions of the node that did not support it.

I'm at a loss as to how to solve this. Suggestions are greatly appreciated.

Edit: I've updated all possible modules in the project in case there might be some sort of conflict, but the problem still persists.

Answer 1

My mistake.

The code I wrote to use worker_threads was originally tested in a pure node.js (sever side) environment. The code ended up being required in a Vue component, which of course is browser based, so of course, worker_threads are not available as they are server side.

A solution would be to make a server API call to the code, or to use something such as threads.js which provides a unified API for worker_threads (sever side) and web workers which are browser based (client side).
