"Uncaught Error: Could not find source file" when using setCompilerOptions on monaco instance

[nickjanssen]

Hello! Thank you for making this library, it's so much better than other monaco editors out there.

Describe the bug
It appears that doing anything with the monaco instance results in Uncaught Error: Could not find source file errors.

To Reproduce

Add the following to your code:

monaco.init().then(monaco => {
  monaco.languages.typescript.javascriptDefaults.setCompilerOptions({
    noLib: true
  });
});

Also be sure to use language="javascript"

Here's a minimally reproducable example:
https://codesandbox.io/s/patient-sky-uykvg?file=/src/App.js

Note that these errors don't show in the Codesandbox console for some reason, you have to actually open your Chrome console to see them.

Hello @nickjanssen. Thank you for feedback.

I've found this issue. I assume it's related to the original library.

I also experienced this issue but was able to fix it by including the default options. Try this:

let options = monaco.languages.typescript.javascriptDefaults.getCompilerOptions()
options.noLib = true // example change
monaco.languages.typescript.javascriptDefaults.setCompilerOptions(options)

Hello @nickjanssen, sorry for the late answer

It was related to the monaco-editor version. Check new versions it's fixed.

let options = monaco.languages.typescript.javascriptDefaults.getCompilerOptions()
options.noLib = true // example change
monaco.languages.typescript.javascriptDefaults.setCompilerOptions(options)

its because you need set allowNonTsExtensions to true
