Golang - Difference between “go run main.go” and c

Question

After writing some scripts in Go I asked myself if there is any difference between the compilation of a .go-file and the later execution and the go run FILE.go command in terms of performence etc.

Are there any advantages if I start a webservice with one of these methods?

Answer 1

go run is just a shortcut for compiling then running in a single step. While it is useful for development you should generally build it and run the binary directly when using it in production.

Answer 2

'go install' command will create shared library compiled file as package.a under pkg folder and exec file under bin directory.

go run command is useful while doing development as it just compiles and run it for you but won't produce binaries in pkg folder and src folder

Answer 3

For DEV (local) environment - use go run,
For PROD environment - use go install this one better than go build because it installs packages and dependencies and you'll have Go toolchain.
