Installation

As an n8n community node (recommended)

In your n8n instance: Settings → Community Nodes → Install and enter:

n8n-nodes-warmy-io

Manual install (self-hosted n8n)

cd ~/.n8n/custom
npm init -y                          # only if ~/.n8n/custom is empty
npm install n8n-nodes-warmy-io
n8n start

In the browser open http://localhost:5678, create a workflow, and search for the Warmy node.

Credentials setup

1. In n8n: Credentials → New → Warmy API.
2. Fill in:
   • API Token — generate on warmy.io → Workspace → Settings → API Keys.
   • Holder UID — get it from warmy.io/api-documentation.
3. Press Test — should return success.

Local development

Requires Node.js 22 LTS (n8n's native isolated-vm won't build on Node 25+).

git clone https://github.com/skachkiss/n8n-nodes-warmy-io.git
cd n8n-nodes-warmy-io
npm install
npm run build                        # tsc → dist/, then gulp copies icons
npm link                             # expose the package globally

cd ~/.n8n/custom
npm init -y                          # only if not already initialised
npm link n8n-nodes-warmy-io

n8n start

n8n loads custom nodes once at startup — restart the process after every npm run build. The browser also caches the SVG icon aggressively; hard-refresh (Cmd+Shift+R) if a logo change doesn't appear.

Dev scripts

npm run dev      # tsc --watch (does NOT re-copy icons; rerun build if svg changes)
npm run lint     # eslint via eslint-plugin-n8n-nodes-base
npm run lintfix  # auto-fix most n8n-nodes-base lint rules
npm run format   # prettier

Adding a new resource

1. Read the relevant section of the Warmy OpenAPI spec.
2. Create nodes/Warmy/descriptions/<Resource>Description.ts exporting <resource>Operations and <resource>Fields.
3. Re-export from nodes/Warmy/descriptions/index.ts.
4. In nodes/Warmy/Warmy.node.ts: add the resource value to the resource dropdown, spread the new operations/fields, and add a dispatch branch in execute() calling your execute<Resource> function.
5. npm run build && npm run lintfix.
