VSOP

VSOP is a fork of GIN that adds an interactive dashboard.

VSOP is currently a work in progress

Introduction

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

Features

Monitor sub folders using fsnotify
Log watcher
- A regex find and filter
- tail -f style auto scrolling
dep support
Desktop notification on Windows 10 (without or with bash see below) / Linux / OSX using notificator

Installation

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

go get github.com/SamHennessy/vsop

Then verify that vsop was installed correctly:

vsop -h

Basic usage

vsop 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
   --godep, -g                   use godep when building
   --buildArgs value             Additional go build arguments
   --certFile value              TLS Certificate
   --keyFile value               TLS Certificate Key

   --notifications               enable desktop notifications
   --help, -h                    show help
   --version, -v                 print the version

Supporting VSOP in Your Web app

vsop 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.

Using flags?

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

Known Issues

Unable to delete folders

You may get an error when trying to delete a folder while VSOP is running. When this happens stop VSOP and delete the folder. This issue can cause a real mess when switching between branches in git or similar tool.

Development

Setup

dep ensure -vendor-only

After you make a change

go install
