Removing package.json or part of it from app in electron-forge

Question

I have started using electron-forge. My package.json is begin added to the final output after making and packaging.

The package.json contains info which I dont want to to be in production. Such as devDependencies or scripts. Putting package.json in forge.config.js ignore list breaks the build.

Is there a way to remove the file or hide ceratin parts of it in the final packaged app?

Use the postPackage hook within your forge.config.js file, like so for example:

{
    hooks: {
        postPackage: async (forgeConfig, options) => {
            console.info('postPackage() Packages built at:', options.outputPaths);
            if (!(options.outputPaths instanceof Array)) {
                return;
            }
            const packageDotJson = path.join(options.outputPaths[0], 'resources', 'app', 'package.json');
            const content = fs.readFileSync(packageDotJson);
            const json = JSON.parse(content.toString());
            Object.keys(json).forEach((key) => {
                switch (key) {
                    case 'name': {
                        break;
                    }
                    case 'version': {
                        break;
                    }
                    case 'main': {
                        break;
                    }
                    case 'author': {
                        break;
                    }
                    case 'description': {
                        break;
                    }
                    default: {
                        delete json[key];
                        break;
                    }
                }
            });
            fs.writeFileSync(packageDotJson, JSON.stringify(json, null, '\t'));
        },
    }
}
