Distributing applications and code in Go involves utilizing three primary methods tailored to different needs: publishing code as packages for others to import, sharing open-source applications for users to install, and deploying binaries for end-users who may not wish to engage with the Go toolchain. A public GitHub repository serves as the central hub for sharing both packages and applications, ensuring accessibility and facilitating installation via commands like `go get` and `go install`. Additionally, distributing binaries across different operating systems and architectures can be achieved through the `go build` command with specific environment variables to target desired platforms. Understanding licensing—such as choosing between permissive (MIT) and restrictive (GPL) licenses—is crucial for protecting both creators and users when sharing open-source code. With these foundational practices, developers can effectively share their work with the broader community.
