How Can I Automate Go Server Recompilation and Reloading on File Changes Across Platforms?

Auto-Recompiling and Reloading a Go Server on File Changes

Developing Go applications can be time-consuming, especially with the need to manually recompile and reload the server after making code changes. Fortunately, there are solutions that can automate this process, ensuring seamless development.

Cross-Platform Auto-Recompilation and Reloading

One of the key requirements mentioned in the original question is cross-platform compatibility. A popular solution for this is Nodemon, a Node.js package that monitors file changes and triggers actions accordingly.

To use Nodemon for auto-recompilation and reloading in a Go application:

1. Install Nodemon: Run npm i -g nodemon to install Nodemon globally.

2. Execute Nodemon: Navigate to the application directory and execute the following command:

   nodemon --watch './**/*.go' --signal SIGTERM --exec 'go' run cmd/MyProgram/main.go

   This command will:

   • Monitor all .go files in the current directory and its subdirectories for changes.
   • Send a SIGTERM signal to the running Go process whenever a change is detected.
   • Recompile and run the Go application using the command go run cmd/MyProgram/main.go.

By leveraging Nodemon, developers can benefit from cross-platform auto-recompilation and reloading of their Go applications. This enhances productivity and ensures a smooth development workflow.
