Gremlin support in NodeJS

[Brijesh Gopal]

Hi All,

I am new to Gremlin and hence please pardon my ignorance.

We are evaluating our options for a new project which uses Orient for Graph. Any recommendations on a Node project that works with Gremlin?

I could not find many options in my search.

Thanks,

Brijesh

Welcome to Gremlin and JavaScript Brijesh,

If you're looking for a generic TinkerPop 3 Gremlin Server client written in Node.js, you can use https://www.npmjs.com/package/gremlin. It's meant to work with any TinkerPop3 implementation via Gremlin Server and it should work out of the box with OrientDB TP3 implementation (see: https://github.com/orientechnologies/orientdb-gremlin)

 

OrientDB has an official Node.js driver (https://github.com/orientechnologies/orientjs) but it doesn't seem to support sending Gremlin queries yet. See this open issue: https://github.com/orientechnologies/orientjs/issues/11.

Using either solutions, you'll most likely find useful to use https://github.com/jbmusso/gremlin-template-string which helps you generate Gremlin query objects (script + bound params) using ES6 template strings. Not mandatory, but useful if your JavaScript runtime support them, and/or if you're using a JS-to-JS transpiler such as Babel.

Hi Jean-Baptiste,

I can't get the current javascript driver (https://www.npmjs.com/package/gremlin) to work with the OrientDB TP3 implementation. I've already inserted a few vertices and edges into the "testdb" using the preconfigured gremlin console that came with OrientDB. Could you please help me out a bit, what am I doing wrong?

const gremlin = require("gremlin");
const DriverRemoteConnection = gremlin.driver.DriverRemoteConnection

const graph = new gremlin.structure.Graph()
const g = graph.traversal().withRemote(new DriverRemoteConnection('ws://localhost:8182/testdb'));

g.V().toList().then(function(data) {
   console.log(data)
}).catch(function(err) {
   console.log(err)
})

Thanks,

Zoltan
