Package Setup

To use Caylir with your projects, edit your mix.exs file and add the required dependencies:

defp deps do
  [
    # ...
    {:caylir, "~> 1.0"},
    # ...
  ]
end

Application Setup

Graph Definition

Defining a graph connection requires defining a module:

defmodule MyGraph do
  use Caylir.Graph, otp_app: :my_app
end

This defined graph module needs to be hooked up into your supervision tree:

children = [
  # ...
  MyGraph,
  # ...
]

For a more detailed explanation of how to get started with a graph please consult the inline documentation of the Caylir.Graph module.

To configure your connection you can use the application environment:

config :my_app, MyGraph,
  host: "cayley.host",
  port: 42160,
  scheme: "https"

The entry should match the chosen :otp_app and module name defined earlier.

For more information on how (and what) to configure please refer to the inline documentation of the Caylir.Graph.Config module.

Usage

Querying data:

MyGraph.query("graph.Vertex('graph').Out('connection').All()")

Writing Data:

MyGraph.write(%{
  subject: "graph",
  predicate: "connection",
  object: "target"
})

Deleting Data:

MyGraph.delete(%{
  subject: "graph",
  predicate: "connection",
  object: "target"
})

A more detailed usage documentation can be found inline at the Caylir.Graph module.
