Module and dependencies

Summary of the Go tooling around module and dependencies handling.

Project Files

go.mod: lists dependencies of a module
go.sum: contains hash of module dependencies that will be verified

Dependencies

go mod tidy: updates the go.mod file by adding missing dependencies, removing not needed ones.

Vendoring

A special mode where all dependencies are stored in the project folder (in a vendor directory) instead of be downloaded from the internet.

go mod vendor: creates a vendor directory with a copy of all dependencies.
