Finding the Extension for a Node

A workflow from a colleague opens with a red “node not available” marker, or you read about a node and want to try it. In both cases you need to know which extension ships the node and where to install it from. NodePit has the answer for every node it knows.

Look the node up

Search for the node by name to get its ID:

curl -s "https://nodepit.com/api/search?query=qr%20code&kind=node&limit=3" \
  | jq '.items[] | {name, nodePitId}'

Then ask for the node with that ID, and keep the fields that name the extension and its update site:

curl -s "https://nodepit.com/api/nodes/io.qrocodile.api.designer.node.QrDesignerNodeFactory" \
  | jq '{extension: .featureName, updateSite: .updateSiteUrl}'

The answer has the name of the extension and the address of its update site. The update site depends on the KNIME version, so add knimeVersion to the request if you do not use the latest one. See Concepts.

Install the extension

In KNIME, add the address as an update site and install the extension from it. Installing Nodes walks through the steps.

With an AI assistant

Ask a connected assistant:

What do I have to install to get the QR Code Designer node?

It looks the node up and answers with the extension and the update site. See Connecting an AI Assistant if you have not connected one yet.
