noflo-polymer

This project provides a binding between Polymer web components and NoFlo, allowing Polymer components to be used as components in a NoFlo graph. The attributes of a Polymer element become the input ports of the NoFlo component, and the events emitted by the Polymer element become the output ports.

Status

In production with noflo-ui

Installation

Add this component to your dependencies:

``bash
$ npm install noflo-polymer --save
`

In addit you need a working setup of Polymer and NoFlo.

Usage

Since Polymer elements don't support introspection yet, you need to utilize the noflo-polymer custom element for informing NoFlo of the attributes and events of your custom elements.

For example:

`html

`

After this you'll have a polymer/the-graph component available with the following ports:

* Input
- element (for providing an element instance either queried from DOM or as a result of document.createElement
- graph (modifies the graph attribute)
- width (modifies the width attribute)
- height (modifies the height attribute)
* Output
- element (the same element instance, passed through
- changed (sends output when the element fires a changed event)

Changes

* 3.0.0 (November 04 2020)
- Ported to Polymer 3.x
* 2.0.1 (November 10 2017)
- Made noflo-polymer not import polymer.html since paths may be different in production use. Consumers must import it themselves
- Added a true payload to the noflo:ready` event emitted when a Polymer element is bound to a NoFlo component instance
* 2.0.0 (November 10 2017)
- Ported components from CoffeeScript to ES6
- Upgraded Polymer from 1.x to 2.x
