My team develops different micro services with Node, using tools such as Typescript, ESLint, and Prettier among others. These tools have configuration files that are located in the project root. (This is important, because git submodules, as far as I understand, can only be used on selected sub-folders).
We change this configuration files from time to time, as our tools improve and offer new capabilities. However, its tiresome to copy these new settings to all the different services we maintain. What's a good way to sync them between different projects and keep things DRY?
