Essential Go Commands Every Backend Developer Should Master

More and more companies are adopting Go for development because it is easy to learn and has low entry cost. Several commands are frequently used. Before any Go operation, you need to install the Go compiler. You can check if it is installed by running: go version If installed, you should see the version number; otherwise, install it from the official site: go.dev/dl/ . go version go1.18.2 darwin/arm64 To inspect Go-related environment variables such as GOROOT or GOPATH, run go env and view their configuration. For details, see the article on understanding GOPATH and GOROOT.

After setting up the development environment, you can start coding. The first command you might run is: go mod init <project name> This initializes a go.mod file, similar to pom.xml in Java or package.json in JavaScript, containing a collection of dependency references.

Next, install any third‑party libraries or frameworks you need: go get <package name> When you have finished coding and want to run the project to see the expected results, execute: go run . Go can also compile the entire codebase into a single binary quickly. Use:

go build -o <name of binary> <packages>

Before pushing code to the repository, format it with: go fmt If you have removed frameworks from the codebase but the go.mod file still lists unused modules, clean them up with: go mod tidy Go also supports unit testing without affecting existing functionality. Run tests with: go test . Another useful command is go vet. Vet checks Go source code and reports suspicious constructs, such as mismatched Printf arguments. While its heuristics cannot guarantee all reports are real issues, it can find errors not caught by the compiler.
