Introducing Custom Nodes and the Losant Node Catalog

Today's update provides a powerful new way to extend the functionality of Losant's workflow engine. With the introduction of Custom Nodes, you can easily develop integrations to third-party services, create custom data processing routines, and build any other functionality specific to your business or application.

Custom Nodes can greatly reduce your application development time by bundling up common tasks into easily reusable and shareable nodes.

 

Custom Nodes

Custom nodes are available for all sandbox and organization users and can be accessed under the main Workflows -> Custom Nodes application menu item.

List of Losant Custom Nodes

From this page you can add and develop a new Custom Node or import an existing one. Custom Nodes are developed a lot like normal workflows, and are made by combining other nodes together into a reusable bundle. Your nodes can have a custom name, description, icon, and user inputs.

Implementation of the Downsample Losant Custom Node

Once the node is saved, it will automatically show up in the workflow palette and can easily be added to your workflows just like any other node.

Example of how to use the Moving Average Losant Custom Node

To get started, please read the Custom Node documentation, which includes a full walkthrough of how to develop an example node that implements the Dark Sky API for weather data.

Custom nodes are currently limited to cloud workflows. We're using this time to fine tune the implementation and implement feedback prior to making them available for edge and hybrid workflows.

Losant Node Catalog

Along with the release of Custom Nodes, we've also launched the Losant Node Catalog, which is a public repository of contributed nodes. The Node Catalog is a great way for Losant partners to get their product or service in front of the Losant developer community.

Losant Node Catalog Github repo

Using nodes from the catalog is extremely easy. You simply download the .node file for the node you'd like to use and import it into your Losant application.

With Custom Nodes and the Node Catalog, you no longer have to wait for Losant to implement new workflow functionality. The ability to add additional capabilities above and beyond the built-in nodes is now in your hands. We can't wait to see what you build!
