All interaction with Neo4j is done through the Cypher monad. Use cypher to add a query to the monad.

type LuceneQuery = ByteStringSource
cypherCreate :: (ToJSON a, FromJSON b) => a -> Cypher bSource
Create a cypher node
cypherGet :: (ToJSON a1, FromJSON a) => a1 -> Cypher aSource
Get the nodes matching the given lucene query
cypherSet :: (ToJSON a, ToJSON a1) => Entity a -> a1 -> Cypher ()Source
Set cypher properties. This currently cannot be done through cypher queries.
luceneEncode :: ToJSON a => a -> LuceneQuerySource
Convert an object to a Lucene query encoded as an ByteString.
withCypherManager :: (Manager -> ResourceT IO a) -> Cypher aSource
Get the http connection manager for a Cypher monad
data CypherException Source
An error in handling a Cypher query, either in communicating with the server or parsing the result
Information about your neo4j configuration needed to make requests over the REST api.
