Monaco editor not using web workers

[andreimc]

• code-server version: off the serviceworker branch
• OS Version: ubuntu 18.04

Description

If we enable web workers for monaco maybe we could use: https://github.com/Microsoft/monaco-editor-webpack-plugin or parts of it that enable the worker for monaco.

This would create a significant advantage since it will take monaco off the main thread.

simpleWorker.ts:35 Could not create web worker(s). Falling back to loading web worker code in main thread, which might cause UI freezes. Please see https://github.com/Microsoft/monaco-editor#faq

simpleWorker.ts:37 Cannot find module './workerMain.js'

Steps to Reproduce

1. Merge the Added serviceworker and web-manifest #154
2. Run code server - look at console

Closing since the editor service runs in a worker.
