How to work with express+cluster?

Question

JavaScript

The Internet is full of simple examples of how to use express + cluster together. But more complex things become more difficult to do. For example, there is an action that I would like to do only 1 time. For example, accessing an external api on a timer to get exchange rates. Do it on the true branch of cluster.isMaster? It doesn't seem right to me

Answer 1

move similar logic to a microservice - 1 background process, not in a cluster for periodic actions, such as a request to an external api
