Duaer node reference

A Duaer node package holds node files, credential files, and codex files, all listed in package.json.

Files in the package

Node file *.node.ts: display name, icon, parameters, and declarative routing or execute().
Credential file *.credentials.ts: fields, the auth method, and an optional connection test.
Codex file *.node.json: categories, aliases, and doc links that place the node in the Duaer node panel.
nodes and credentials under the n8n key in package.json: the files in dist/ to load. Duaer does not load files that are not listed.

Returned data

Every output item must trace back to an input item so Duaer expressions and later nodes can find the matching data. Programmatic nodes set this themselves; refer to Paired items.

Questions

Why does Duaer not show a node I added?

Check that package.json lists its dist/ file under the n8n key, then rebuild and publish a new version. Duaer loads only the listed files.

Create nodes

Set paired items in a Duaer node

A programmatic Duaer node must tell Duaer which input item each output item comes from, or expressions downstream cannot find the data.

Create nodes

Build a Duaer node

Scaffold a project with the node CLI, write the node and its credential, lint and build it, then try it in Duaer.

Create a custom node for Duaer

Write a node package for Duaer when built-in nodes and custom operations are not enough and you will reuse the step.
