Custom Nodes & Extensibility

Interplay’s node palette is not a fixed list. Anything the platform does not already integrate with can be added — generated from a description, installed from a registry, or written by hand — and once installed a custom node behaves exactly like a built-in one.

Can Interplay generate a node for me?

Section titled “Can Interplay generate a node for me?”

Yes. Describe the node you need in plain English and Interplay drafts, generates, and deploys it directly into your palette, ready to drag onto a canvas. This is the fastest route to a connector for an internal or niche API: instead of scaffolding a node package by hand, you describe the endpoint and the shape of the data you want out.

How do you install existing nodes?

Section titled “How do you install existing nodes?”

Three routes, all from the editor:

  • Node registry — browse and install from a curated registry of published nodes; missing dependencies for an imported flow can be resolved in one action.
  • npm — search npm for community node packages and install a chosen version.
  • Upload — install a node package directly into the workspace.

Installed nodes can be pinned to specific versions and uninstalled cleanly.

Can you write nodes by hand?

Section titled “Can you write nodes by hand?”

Yes. Nodes are standard packages with a runtime file and an editor definition, so a developer can author one in JavaScript, or wrap Python logic through the Python function node. In-flow function nodes cover the common case where a few lines of custom logic are needed without publishing a reusable node at all — with Python virtual-environment creation and package installation available from the editor’s library tab.

What else can be extended?

Section titled “What else can be extended?”
  • Databases — MySQL, PostgreSQL, and MongoDB can be provisioned and connected from the platform, with a built-in database browser for inspecting data.
  • Templates and starter apps — bundled demo applications can be installed, modified, and re-saved as your own templates.
  • Workflow import — flows and mappings can be converted in from other automation tools, so existing automations can be brought onto the platform rather than rebuilt from zero.
  • Chat and dashboard surfaces — chatbot widgets and dashboard apps let a flow be published to end users without a separate front-end project.
