Working with the List Asset Migrations Node

In this quick tutorial, we will cover Working with the List Asset Migrations Node. In this tutorial, we will create a flow containing the List Asset Migrations Node.

This node can be used in two modes: “Interactive” and “Run-Time.” Here, we will cover both of these modes.

In interactive mode, the end user clicks on the action button attached to the node, and the Catenis API method is called using the default settings. You are not required to provide any input for nodes that support interactive mode.

In this video we will cover:

• How is this node used in run-time mode
• How is this node used in interactive mode
• Deploying and testing your flow

Prerequisite

• A Free Catenis Development account or Production account
• Node-RED installed on either a local or cloud environment
• Catenis Flow Pallet installed on Node-RED
• A Catenis Virtual Device configured on Node-RED
• Basic understanding of how to use Node-RED
• Basic understanding of the List Asset Migration Node

Working with the List Asset Migrations Node is the last video in the Catenis Flow tutorial series! Great work!

Hi, this is Claire for Blockchain of Things.

In this tutorial, we’ll create a flow containing the List Asset Migrations Node.

If you don’t know what a List Asset Migrations Node is,

make sure you check out the previous tutorial,

titled, “Understanding the List Asset Migrations Node”.

This node can be used in two modes, Interactive and RunTime.

First, let’s go over how to use this node in RunTime Mode.

Drag-and-drop the List Asset Migrations Node from the Catenis Flow palette into your workspace.

Double-click on the node to display the properties slide-out panel.

Select your Catenis Virtual Device,

and add the node’s configuration information to each field of the properties slide-out panel.

Then, wire this node ,to a Debug Node.

Next, drag-and-drop an Inject Node to the Node-RED workspace.

Wire, the Inject Node to the List Asset Migration Node,

and double-click the Inject Node to open its property slide-out panel.

Select the payload field,

choose the JSON type,

then click the ellipse button to display a JSON edit box.

Enter the JSON information you wish to pass as input to the Catenis Node.

For example, something like this:

After entering your JSON information,

click the done button.

Then click the done button again, and click deploy.

Click the button attached to the Inject Node to send

the input from the Inject Node through the flow.

The Debug Sidebar should display the returned JSON object containing the API call results.

Great work!

Now, pause the video and explore this flow if you’d like.

Now, we’re going to learn how to use this node in Interactive Mode.

Clear your workspace to make room for the next flow.

Drag-and-drop the List Asset Migrations Node into your workspace.

Double-click on the node to display the properties slide-out panel.

Select your Catenis Virtual Device and add the node’s configuration

information to each field of the property slide-out panel.

Then, wire this node, to a Debug Node.

Click deploy.

Then click the button on the left attached to this node to send the

default property panel setting to the Catenis APIs and through the flow.

The Debug Sidebar should display the returned JSON object.

Great work!

You should now understand how to use the List Asset Migrations Node

in both Interactive Mode and RunTime Mode.
