Reload

reload is a fork of the gin project originally written by Jeremy Saenz.

reload is a command line utility for live-reloading Go web applications. Just run reload in your app directory and your web app will be served with reload as a proxy. reload will automatically recompile your code when it detects a change. Your app will be restarted the next time it receives an HTTP request (unless the --immediate flag is passed).

reload adheres to the "silence is golden" principle, so it will only complain if there was a compiler error or if you successfully compile after an error.

Installation

Assuming you have a working Go environment and GOPATH/bin is in your PATH, reload is a breeze to install:

go get -u github.com/n3integration/reload

Then, verify that reload was installed correctly:

reload -h

Basic usage

reload [options] run main.go

Options

   --laddr value, -l value       listening address for the proxy server
   --port value, -p value        port for the proxy server (default: 3000)
   --appPort value, -a value     port for the Go web server (default: 3001)
   --bin value, -b value         name of generated binary file (default: "gin-bin")
   --path value, -t value        Path to watch files from (default: ".")
   --build value, -d value       Path to build files from (defaults to same value as --path)
   --excludeDir value, -x value  Relative directories to exclude
   --immediate, -i               run the server immediately after it's built
   --all                         reloads whenever any file changes, as opposed to reloading only on .go file change
   --buildArgs value             Additional go build arguments
   --certFile value              TLS Certificate
   --keyFile value               TLS Certificate Key
   --logPrefix value             Setup custom log prefix
   --notifications               enable desktop notifications
   --help, -h                    show help
   --version, -v                 print the version

Supporting Reload in Your Web App

reload assumes that your web app binds itself to the PORT environment variable so it can properly proxy requests to your app.

Using flags?

When you normally start your server with flags if you want to override any of them when running reload we suggest you instead use github.com/namsral/flag as explained in this post
