J'ai suivi ce tuto pour débuter avec electron. Le but semi-final de mon appli : générer un setup cross-platform (.exe, .msi, ...) qui puisse installer mon appli Angular sur Windows, Linux, ...
How to create Angular Desktop Apps

Mes fichiers sont tous identiques au tuto (copié/collé) sauf ".angular-cli.json" que je n'ai pas donc j'ai mis ce code dans "angular.json" que voici (lignes ajouté en gras)
