I’m developing my custom API by writing code in controllers, graphql schema files, and services, as shown in the documentation. But I’m extracting a lot of utility functions that I’d like to share between different services. What is the best or conventional place to put them? Should I create a top-level src directory and just require('../../../src/someUtility.js')? It doesn’t seem very clean and I’m wondering if it wouldn’t play well with auto-reloading and other Strapi features.
