我应该用go run运行服务器。 或./main和有什么区别?

I have a go server which I normally run like this:

go build . && ./main

But online I see many examples using go run . which is better to use and what is the difference?

    From official documentation (go1.11):

    go run - compiles and runs the named main Go package.

    go build - compiles the packages named by the import paths, along with their dependencies, but it does not install the results.

    go install - compiles and installs the packages named by the import paths.

    It means:

    Usually for LOCAL environment it's ok to use go run,
    but for PROD environment it's better to build your app with go build and run ./main,
    but in case you need Go toolchain you must use go install because it installs packages and dependencies and run ./bin/main (it may make sense in dev/stage environment).
