To reproduce create a project, use the component and then try to compile using ng packagr

I'm using version 3.3.0-rc.3 of the editor and have codemirror version 5.34.0 as a peer dependency.

That's odd. I was using that version in our product. Which is in production actually.

You can see a working example here: https://ngx-editor.stackblitz.io/ Code for the example: https://stackblitz.com/edit/ngx-editor

Are You using ng-packagr to pack your code having this editor?

if so, try adding this to your ngPackage configuration

https://github.com/Sibiraj-S/ngx-editor/blob/62f4522c1fabebfd700468c399d3df8fb3148659/ng-package.json#L5-L10

Post More Information such as

1. Angular version
2. Operation System
3. Nodejs version

If nothing helps.

@stephanos199 . Did that help?

[stephanos199]

I only had to add

{
  "$schema": "./node_modules/ng-packagr/ng-package.schema.json",
  "lib": {
    "entryFile": "public_api.ts",
    "externals": {
      "codemirror": "codemirror"
    }
  }
}

I was missing the "externals" declaration

[sibiraj-s]

So Is it working now?

[stephanos199]

Yes
