** Getting started

*Cloud* is a [[https://golang.org/][golang]] application and you are going to need golang
toolchain to compile the app.

To install or update run:

#+BEGIN_SRC shell
go get -u github.com/ap4y/cloud/cmd/cloud
#+END_SRC

Web UI is implemented using [[https://reactjs.org/][react]] and is pre-bundled into golang
app. To setup local development environment for react app you will
need [[https://nodejs.org][node.js]] with either ~npm~ or ~yarn~. 

To pull react app dependecies run:

#+BEGIN_SRC shell
cd app
npm install
#+END_SRC

To start local development setup:

#+BEGIN_SRC shell
cd app
npm start
#+END_SRC

This will start ~creat-react~ web server on a port ~3000~, you can proxy
local ~cloud~ app to it using ~-devURL~ argument.

** Configuration

*Cloud* uses ~json~ config files to setup authentication and necessary paths. [[https://github.com/ap4y/cloud/blob/master/config.example.json][Sample config]]:

#+BEGIN_SRC js
{
  "jwt_secret": "secret",
  "modules": ["gallery"],
  "users": {
    "ap4y": "$2b$10$fEWhY87kzeaV3hUEB6phTuyWjpv73V5m.YcqTxHXnvqEGIou1tXGO"
  },
  "share": {
    "path": "./"
  },
  "gallery": {
    "path": "/mnt/media/Photos/Export/",
    "cache": "/tmp/cloud/"
  },
  "files": {
    "path": "/mnt/media/Photos/Export/"
  }
}
#+END_SRC

Configuration fields:

- ~jwt_secret~ is a secret used for [[https://jwt.io/][JWT]] (~HS256~ algorithm) related operations.
- ~modules~ defines enabled modules.
- ~users~ defines ~bcrypt~ hashes for user credentials, you can use
  ~mkpasswd~ to hash your passwords.
- ~share~ setups a share storage. ~path~ defines storage location for
  a disk share storage.
- ~gallery~ defines necessary paths for the gallery module. ~path~ is
  a gallery source folder and ~cache~ is a thumbnail cache folder.
- ~files~ defines necessary paths for the files module. ~path~ is
  a source folder for this module.

Additionally following command line arguments are supported:

- ~-config cloud.json~ - path to a config file.
- ~-addr :8080~ - address to listen on.
- ~-devURL~ - enables proxy mode for a local react development server.

** Gallery

Gallery provides common image gallery features: image grid, thumbnails
and full screen previews. Gallery traverses provided ~path~ on a disk
and exposes folders with images as shareable galleries. Thumbnails are
generated on the fly and cached for subsequent use.

** Files

Files provides file viewer interface with a basic management
features. Files module traverses provided ~path~ on a disk and
construct a tree, parts of the tree can be individually shared.
