Neo4j.Sips
==========
A simple Elixir wrapper around the Neo4j graph database REST API. It is aiming to help Elixir developers to play with [Neo4j](http://neo4j.com/developer/get-started/), and to eventually become the main support for a future [Ecto](https://github.com/elixir-lang/ecto) adapter.
### Install
Edit mix.ex and add the `neo4j_sips` dependency to the `deps/1 `function:
defp deps do
[{:neo4j_sips, github: "florinpatrascu/neo4j_sips"}]
end
Or, if you're using a local development copy:
defp deps do
[{:neo4j_sips, path: "../neo4j_sips"}]
end
Then add the `neo4j_sips` dependency the applications list:
def application do
[applications: [:logger, :neo4j_sips]]
end
Run `mix do deps.get, deps.compile`
Edit the `config/config.exs` and describe a Neo4j server endpoint, example:
config :neo4j_sips, Neo4j,
url: "http://localhost:7474"
If your server requires basic authentication, add this to your config file:
basic_auth: [username: "foo", password: "bar"]
Or:
token_auth: "bmVvNGo6dGVzdA==" # if using an authentication token?!
### Example
With a minimalist setup configured as above, and a Neo4j server running, we can connect to the server and run some queries using Elixir’s interactive shell ([IEx](http://elixir-lang.org/docs/stable/iex/IEx.html)):
$ cd <my_mix_project>
$ iex -S mix
Erlang/OTP 18 [erts-7.1] [source] [64-bit] ....
Interactive Elixir (1.1.1) - press Ctrl+C to exit ....
iex(1)> alias Neo4j.Sips, as: Neo4j
iex(2)> cypher = """
CREATE (n:Neo4jSips {title:'Elixir sipping from Neo4j', released:2015,
license:'MIT', neo4j_sips_test: true})
"""
iex(3)> Neo4j.query(Neo4j.conn, cypher)
{:ok, []}
iex(4)> n = Neo4j.query!(Neo4j.conn, "match (n:Neo4jSips {title:'Elixir sipping from Neo4j'}) where n.neo4j_sips_test return n")
[%{"n" => %{"license" => "MIT", "neo4j_sips_test" => true, "released" => 2015,
"title" => "Elixir sipping from Neo4j"}}]
iex(5)>
