n8n-nodes-infranodus

This is an n8n community node from InfraNodus. It lets you use InfraNodus GraphRAG API in your n8n workflows.

You can create and use knowledge graphs as experts in your LLM workflows (no OpenAI keys required). InfraNodus can provide information about the main topics and content gaps in any text, so you can use it in your marketing and research workflows.

You can also use the knowledge graphs to augment and improve your RAG flows with graph-based AI advice about the structure of the knowledge and better quality retrieval without the need to set up complex vector store infrastructures.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

$3

1. Open the nodes panel at the top right of your n8n editor (+ button)
2. Search for "InfraNodus"
3. Click on the "Install" button

$3

You can install this node manually if you're running a local version of n8n.

0. Install the local version of n8n

If you don't have n8n installed yet, you can install it using

- n8n Docker installer (in this case you'll need Docker installed)

``bash
docker volume create n8n_data

docker run -it --rm \
--name n8n \
-p 5678:5678 \
-e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true \
-e N8N_RUNNERS_ENABLED=true \
-v n8n_data:/home/node/.n8n \
docker.n8n.io/n8nio/n8n
`

- through the command line in your terminal using the n8n NPX installer — for temporarily launching n8n without installing it (in this case, you'll need node version 20 or 22 installed).

`bash
npx n8n
`

- through npm n8n node package manager (in this case you install it globally and can launch it from your termainal)

`bash
npm install n8n -g
`

In all cases, your configuration settings will be saved even if you quit at this folder, where you can also install the InfraNodus node:

`bash
cd ~/.n8n
`

1. Launch the local version of n8n

- If it's installed globally:

`bash
n8n start
`

- If it's installed through Docker:

Start the Docker n8n instsance:

`bash
docker run -it --rm \
--name n8n \
-p 5678:5678 \
-e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true \
-e N8N_RUNNERS_ENABLED=true \
-v n8n_data:/home/node/.n8n \
docker.n8n.io/n8nio/n8n
`

Then access the Docker shell (terminal entry into your Docker n8n instance):

`bash
docker exec -it n8n sh
`

1. Install the node

Change to the nodes folder:

`bash
cd ~/.n8n/nodes
`

If it doesn't exist, create it first:

`bash
mkdir -p ~/.n8n/nodes
`

2. Install the node into this folder:

`bash
npm install n8n-nodes-infranodus
`

3. Then restart n8n

Local Node Development

If you're using the node on your local machine, you can link your local InfraNodus n8n node to your local n8n instance.

Then you can modify the resources and requests using the InfraNodus API. You can also add new custom tools.

If you have InfraNodus running locally, you can replace the baseUrl with your local InfraNodus instance address (default is https://infranodus.com/api/v1).

In order to start local development, you need to link your local InfraNodus n8n node to your local n8n instance, so every time you change the code in the InfraNodus n8n node, it updates in n8n as well.

0. Create a copy of this repository on your local machine

1. Go to this node's folder on your local machine and install dependencies

`bash
npm install
`

2. Make the necessary changes and build the node

`bash
npm build
`

3. Make sure you're in the InfraNodus node's folder and run:

`bash
npm link
`

3. Then go to the locally installed n8n/nodes folder, usually at

`bash
cd ~/.n8n/nodes
`

4. Link the local InfraNodus n8n node package to the n8n instance:

`bash
npm link n8n-nodes-infranodus
`

This will make your local n8n instance refer not to the generally available npm package but to the local infranodus n8n node instance you linked to.

5. Then run the n8n instance locally using the

`bash
n8n start
`

$3

To have the updates reflected in n8n, you need to:

1. Run the build command in the node's folder

`bash
npm run build
`

2. Restart n8n:

`bash
n8n start
``

Operations

The node supports the following operations:

- Create a knowledge graph
- Get a knowledge graph
- Generate a question based on the content gaps in a knowledge graph
- Prompt a knowledge graph expert

Credentials

The node requires an API token from InfraNodus. You can get it from your InfraNodus account.

We use Bearer authentication in case you want to build your own node using InfraNodus.

Compatibility

The node is compatible with n8n v0.225.0 and above.
