How Can I Auto-Recompile and Reload a Go Server Cross-Platform on File Changes?

Auto-Recompiling and Reloading Go Server on File Changes

Automating the process of recompiling and reloading a Go server upon file changes is crucial for efficient and iterative development. This question delves into finding cross-platform solutions to this common challenge.

The inquiry begins with a mention of AppEngine's inherent auto-recompilation and reload capabilities. However, the user expresses a need for a similar solution that works outside of the AppEngine environment.

They attempted to use Guard, a Ruby tool for monitoring file changes and executing specified commands. However, their implementation encountered a problem where the foo process failed to enter the background, leaving the script indefinitely hanging.

To resolve this issue, the user seeks suggestions for cross-platform solutions that can effectively recompile and reload a Go server upon any changes to its .go files.

One recommended option involves utilizing nodejs and its nodemon tool. By installing nodemon globally and setting up a command to watch for changes in .go files, one can execute the script to run go run cmd/MyProgram/main.go whenever modifications are detected.

This solution stands out due to its cross-platform compatibility, addressing the user's requirement for a platform-agnostic approach. By leveraging SIGTERM signals and the nodemon watch functionality, changes in the codebase can seamlessly trigger a recompile and reload of the server.
