Neo4j driver (REST API client) for Node.js
This is the modified version of the original package which is not using
If we gain something i will open a merge request to original repo.
This library supports and has been tested against Neo4j 1.4 through Neo4j 1.8.
npm install neo4j
To start, create a new instance of the
GraphDatabase class pointing to your
var neo4j = ;var db = '';
Node.js is asynchronous, which means this library is too: most functions take callbacks and return immediately, with the callbacks being invoked when the corresponding HTTP requests and responses finish.
Here's a simple example:
var node = db; // instantaneous, but...node;
Because async flow in Node.js can be significantly tricky to handle, we strongly recommend using a flow control tool or library to help. Our personal favorite is Streamline.js, but other popular choices are async, Step, Seq, TameJS and IcedCoffeeScript.
Once you've gotten the basics down, skim through the full
API documentation to see what this library can do, and take a
look at @aseemk's node-neo4j-template app for a complete usage
models/User.js file in particular is the one that interacts
with this library.)
Please note that breaking changes to this library are very likely in the
near future as we consider an API overhaul, but the version number will always
respect semantic versioning. So if you specify this library as a
dependency in your package.json, please specify something like
>=0.2.6. Thanks. =)
git clone email@example.com:thingdom/node-neo4j.git cd node-neo4j npm install && npm run clean
You'll also need a local Neo4j database instance for the tests:
curl http://dist.neo4j.org/neo4j-community-1.8.2-unix.tar.gz --O neo4j-community-1.8.2-unix.tar.gz tar -zxvf neo4j-community-1.8.2-unix.tar.gz rm neo4j-community-1.8.2-unix.tar.gz ln -s neo4j-community-1.8.2/bin/neo4j neo4j
If you're new to Neo4j, read the Getting Started page. Start the server:
Stop the server:
To run the tests:
Important: The tests are written assuming Neo4j >=1.7 and will now fail on prior Neo4j versions, but the library supports prior Neo4j versions just fine.
This library is written in CoffeeScript, using Streamline.js syntax.
The tests automatically compile the code on-the-fly, but you can also generate
.js files from the source
._coffee files manually:
npm run build
This is in fact what's run each time this library is published to npm.
But please don't check the generated
.js files in; to remove:
npm run clean
.js files exist, changes to the source
._coffee files will
not be picked up automatically; you'll need to rebuild.
npm link this module into another app (like node-neo4j-template)
and you want the code compiled on-the-fly during development, you can create
index.js file under
lib/ with the following:
;;moduleexports = ;
But don't check this in! That would cause all clients to compile the code on-the-fly every time, which isn't desirable in production.
