GoWebApp

A basic MVC web app in Golang, but with all of the dependencies vendored using GoDep.

Usage

cd ~/go/src
git clone https://github.com/cleesmith/gowebapp.git
cd gowebapp
go build
maybe, edit config/config.json to change various app settings
sudo ./gowebapp
	- why sudo? coz the default is port 80, so edit config/config.json to change it

ToDo's

1. switch from Foundation to Bootstrap
2. use BoltDB instead of MySQL or SQLite
3. reduce the app's footprint to the bare minimum
   • remove the unused dependencies, well, for my typical usage anyways
     • such as the user registration and recaptcha stuff
     • typically, my apps define an admin user who manages other users
   • currently on a Mac the binary file size is 16,370,184
     • which is not too big considering that is everything -- an all-in-one easy to deploy file
4. cross compile doesn't work on a Mac because of the included C file for SQLite

   • GOOS=linux GOARCH=amd64 go build ... yields this error message: shared/database/database.go:9:2: C source files not allowed when not using cgo or SWIG: sqlite3-binding.c

   • and CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build ... yields this error message:

     ```
     

     runtime/cgo

     ld: unknown option: --build-id=none clang: error: linker command failed with exit code 1 (use -v to see invocation) ```

     • http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html

   • solutions:

     • don't cross compile, just install Go on the specific platform then build the app
     • don't use MySQL or SQLite for data storage
     • why? KISS

Godep

Go 1.5:
  - don't do: godep save -r
  - ~/.bash_profile contains:
    export GO15VENDOREXPERIMENT=1
    ... this causes godep to use the vendor folder for dependencies

godep save
  - creates Godeps folder with Godeps.json in there
  - creates vendor folder and copies dependencies into it

go build
  - which will use the vendor folder instead of ~/go/src/whatever

This app works as expected, so by vendoring the dependencies the app should continue to work independent of any future changes to the dependenies on github or other repos.
