JanusGraph-Visualizer

This project is to visualize the graph network corresponding to a gremlin query.

Setting Up JanusGraph Visualizer

To setup JanusGraph visualizer, you need to have node.js and npm installed in your system.

• Clone the project

git clone https://github.com/JanusGraph/janusgraph-visualizer.git

• Install dependencies

npm install

• Run the project

npm start

• Open the browser and navigate to

http://localhost:3000

Note - Frontend starts on port 3000 and simple Node.js server also starts on port 3001. If you need to change the ports, configure in package.json, proxy-server.js, src/constants

Setting up with Docker

You can build a Docker image of the JanusGraph visualizer with the included Dockerfile. This will use the current version of the main branch of the source GitHub repository. The Docker image can be built by calling the docker build -f full.Dockerfile command, for example:

docker build --tag=janusgraph-visualizer:latest -f full.Dockerfile .

If you had already built node project on your host then you can create a Docker image faster by using Dockerfile instead of full.Dockerfile:

docker build --tag=janusgraph-visualizer:latest .

The image can also be downloaded from Docker hub: janusgraph/janusgraph-visualizer:latest.

docker pull janusgraph/janusgraph-visualizer:latest

The Docker image can then be run by calling docker run and exposing the necessary ports for communication. See Docker's documentation for more options on how to run the image.

# if you built the image yourself
docker run --rm -d -p 3000:3000 -p 3001:3001 --name=janusgraph-visualizer --network=host janusgraph-visualizer:latest
# if you downloaded from Docker Hub
docker run --rm -d -p 3000:3000 -p 3001:3001 --name=janusgraph-visualizer --network=host janusgraph/janusgraph-visualizer:latest

Note that --network=host is not needed if you don't run your gremlin server in the host machine.

• Open the browser and navigate to

http://localhost:3001

The Docker container can be stopped by calling docker stop janusgraph-visualizer.

Usage

• Start JanusGraph-Visualizer as mentioned above
• Start or tunnel a gremlin server
• Specify the host and port of the gremlin server
• Write a gremlin query to retrieve a set of nodes (eg. g.V())

Features

• If you don't clear the graph and execute another gremlin query, results of previous query and new query will be merged and be shown.
• Node and edge properties are shown once you click on a node/edge
• Change the labels of nodes to any property
• View the set of queries executed to generate the graph
• Traverse in/out from the selected node

Credits

JanusGraph-Visualizer is based on the original Gremlin-Visualizer that can be found here.
Author of the original Gremlin-Visualizer is: Umesh Jayasinghe.

What is the different in this fork comparing to the origin repo

1. Added suppport for different graph names
2. Added GitHub actions to build & push Docker image
3. Added productions mode to host in Kubernetes
4. Added ability to override default values (graph host, port, name) via environment variables
