n8n community package: LLM Gateway Chat Model node with custom LLM Gateway credential for any OpenAI-compatible gateway (e.g. /v1/chat/completions, /v1/models).

  • Node: Shows in AI Agent → Chat Model dropdown (n8n v1.101+).
  • Credential: API Key + Gateway Base URL; uses Bearer auth like OpenAI.

Installation in n8n

  1. In n8n: Settings → Community nodes → Install a community node.
  2. Enter: n8n-nodes-llmgateway (or your npm package name).
  3. Install. Then add LLM Gateway credential and use LLM Gateway Chat Model in AI Agent.

Artifactory (company private registry): See ARTIFACTORY.md for publish and n8n install steps.

What to do next

  1. Point npm at Artifactory – The repo has an .npmrc that sets the registry to Wayfair’s internal npm (artifactory.service.bo1.csnzoo.com/artifactory/api/npm/npm). No change needed unless your team uses a different registry.
  2. Authenticate and publish – From the repo root run npm login --registry=https://artifactory.service.bo1.csnzoo.com/artifactory/api/npm/npm (use your Artifactory/SSO credentials), then npm publish. The package will be pushed to Artifactory. See ARTIFACTORY.md § 2.1.
  3. Use in n8n – Set N8N_COMMUNITY_PACKAGES_REGISTRY to the same Artifactory npm URL; add .npmrc auth in the n8n container if required. Then in n8n go to Settings → Community nodes and install n8n-nodes-llmgateway. See ARTIFACTORY.md § 3.
