# neo4j-stream-deserializer [](https://travis-ci.org/brian-gates/neo4j-stream-deserializer) [](https://david-dm.org/brian-gates/neo4j-stream-deserializer.png#info=devDependencies)
Project no longer maintained since [cypher-stream](https://github.com/brian-gates/cypher-stream) now depends on [oboe.js](https://github.com/jimhigson/oboe.js) instead.
Streams neo4j responses as formatted objects.
A typical neo4j response:
