# OpenCloud base stack

OpenCloud relies on a micro services architecture.
Each component could be developed using specific technologies.
However, in order to preserve product consistency and ease maintenance activities, we strongly encourage using the following technological stacks.

## Web services

Web services are developped in Go using Beego stack

### Environment setup

When using pricate repositories like the OpenCloud git forge, you should define it as a private repository

    export GOPRIVATE=cloud.o-forge.io

The Beego stack provides the bee cli tool to ease building process :

    go get github.com/beego/bee/v2@latest

### Project initialization

New component creation 

    go mod init oc-mycomponent

Refer to other services component main.go file to write a consitent initialisation process 

### Project build

In order to build the software :

    bee run -downdoc=true -gendoc=true

The -downdoc=true -gendoc=true will automatically generate swagger documentation in the /swagger path

If default Swagger page is displayed instead of your api, change url in swagger/index.html file to :

    url: "swagger.json"

If annotations are modified without any code changed, a rebuild might not reflect the changes.
To force routing information update :

    bee generate routers 

## GUI compoenents

The GUI are developped using Flutter framework

### Environment setup

* Install Flutter framework
* Install Android Studio
* In "Tools"->"SDK Manager"->"Apparenace & Behaviour/System Settings/Android SDK", go to "SDK tools" and tick the "Android SDK command line tools"
* Run <code>flutter doctor</code> commmand and follow instructions to accept SDK licenses
* Add Vscode flutter plugin and use Vscode Command palette to create a Flutter project
* Also set the target Device using command Palette

### Project build

Depending on your target platform :

    flutter build web
    flutter build linux
    flutter build windows
