gin
is a simple command line utility for live-reloading Go web applications. Just run gin
in your app directory and your web app will be served with gin
as a proxy. gin
will automatically recompile your code when it detects a change. Your app will be restarted the next time it receives an HTTP request.
gin
adheres to the "silence is golden" principle, so it will only complain if there was a compiler error or if you succesfully compile after an error.
Installation
Assuming you have a working Go environment and GOPATH/bin
is in your PATH
, gin
is a breeze to install:
go get github.com/codegangsta/gin
Then verify that gin
was installed correctly:
gin -h
Supporting Gin in Your Web app
gin
assumes that your web app binds itself to the PORT
environment variable so it can properly proxy requests to your app. Web frameworks like Martini do this out of the box.
