Importing typescript files in preload script using Electron

Question

I currently have a preload.js script that basically adds variables to the window object for a webview. What I want to do is import a typescript file inside the preload script. The preload only supports commonjs syntax.

Is there any way I can achieve this?

I tried to transpile the file and access the webpack output but it didn't work.

So, the best solution I found was using an external package. First I did publishing it to npm and now I'm using yarn workspaces and simply requiring my package inside preload.js

const = { MyClass } = require('my-workspace-package')

and then I can use it freely inside the file (and also inject it into my window object for instance)
