Cannot read properties of undefined (reading 'extends')

• Electron-Builder Version: 25.0.5

• Node Version: 20.16.0

• Electron Version: 31.4.0
• Electron Type (current, beta, nightly): current

• Target: all

I wanted to move the configuration of electron-builder from package.json to a typescript file named electron-builder.ts.
Running the script electron-builder --dir throws the following error:
Cannot read properties of undefined (reading 'extends')
I tried to rename the config file but had the same error.

Using the js version seems to work (just needs to have a differente name from the default).

Can you try using export default instead of module.exports?

This is how I've set up the typescript config file for my test project. Wondering if the satifies Configuration is causing the subdependency read-config-file (or internally the https://www.npmjs.com/package/config-file-ts package) to throw the error.

import { Configuration } from "app-builder-lib"

const options: Configuration = {
    // options
};

export default options;

@mmaietta thank you!
It worked quadre-code/quadre@b07a2c8
I just used the Configuration type from electron-builder instead of app-builder-lib.

I would be nice to add this to the documentation and how to add the types in the jsdoc comment in a js file.
Also it seems that the configuration file can be something like electron-builder.config.ts even without using the --config command.

You mean jsdoc/intellisense like this? https://www.electron.build/api/programmatic-usage

Oh, didn't see that!
I was only looking here https://www.electron.build/configuration/configuration
