Node codex files
The codex file contains metadata about your node. This file is the JSON file at the root of your node. For example, the HttpBin.node.json{:target=_blank .external-class} file in the n8n starter.
The codex filename must match the node base filename. For example, given a node base file named MyNode.node.ts, the codex would be named MyNode.node.json.
| Parameter | Description |
|---|---|
node |
Includes the node name. Must start with n8n-nodes-base.. For example, n8n-nodes-base.openweatherapi. |
nodeVersion |
The node version. This should have the same value as the version parameter in your main node file. For example, "1.0". |
codexVersion |
The codex file version. The current version is "1.0". |
categories |
The settings in the categories array determine which category n8n adds your node to in the GUI. See Node categories for more information. |
resources |
The resources object contains links to your node documentation. n8n automatically adds help links to credentials and nodes in the GUI. |
Node categories
You can define one or more categories in your node configuration JSON. This helps n8n put the node in the correct category in the nodes panel.
Choose from these categories:
- Data & Storage
- Finance & Accounting
- Marketing & Content
- Productivity
- Miscellaneous
- Sales
- Development
- Analytics
- Communication
- Utility
You must match the syntax. For example, Data & Storage not data and storage.
