Use Cases and Deployment Scope

We have a lot of NodeJS projects in the company I work for. This includes our customer database, which contains millions of records. Many of those projects also have a microservice architecture. In order to keep our code tidy and manageable, we segment it into logical NodeJS modules and use Yarn to install those modules and manage their versions. This is very important to us, as we need to reuse as much code as we can in different microservices (for authentication, calling other APIs, security ...)
