How to use shared Golang code in Serverless Functions?

Asked by Dylan Hughes

How do I use shared code when using Go as a runtime for Digital Ocean Functions? In the documentation, I only see information regarding the usage of external packages, however I wish to have local code that is exposed to other functions part of the same project.

I see the documentation also refers to using the “/lib” folder to achieve this behaviour, however it is not clear how to link Go code written in the “/lib” folder to function code, ready for usage.

In DigitalOcean Functions with Go, you can organize shared code in a /lib directory and reference it in your function files using Go modules.

First, structure your project with a functions/ folder for your functions and a lib/ folder for shared code. Initialize a Go module in your project root with go mod init myproject, then import shared code inside your function file using import “myproject/lib”. When deploying, ensure the /lib folder is included.
