Body
Wire any element up to HAX
Usage
Video showing how we integrate HAX with elements
HAX body behaviors provide a consistent way to rapidly wire Polymer elements up to HAX. While anything can talk to HAX via consistent property and event usage, these body behaviors reduce the time and increase accuracy when trying to wire to HAX (drastically).
The major is in HAX Schema defintion which can be translated to JSON Schema with a single function. This allows for rapidly building out headless "forms" in HAX while the elements themselves just define the JSON blob as to how it should function and what should be wired where. It's more complicated then it sounds.
Examples
For full documentation just open the lib/HAXWiring.js file as it's got a lot of documentation but here's the relevent parts from example-hax-element.
import { HAXWiring } from "@lrnwebcomponents/hax-body-behaviors/lib/HAXWiring.js";
class ExampleHaxElement extends HTMLElement {
...
// haxProperty definition
static get haxProperties() {
return {
canScale: true,
canPosition: true,
canEditSource: false,
gizmo: {

}
};
}
// properties available to the custom element for data binding
static get properties() {
return {
title: {
name: "title",
type: "String",
value: "My Example"
},
available: {

/**

connectedCallback() {
this.HAXWiring = new HAXWiring();
this.HAXWiring.setup(
ExampleHaxElement.haxProperties,
ExampleHaxElement.tag,
this
);
}

Here's a much more complex example from a Polymer Legacy style element who calls attached when it is fixed to the DOM (video-player/video-player.js):
/**
* Attached.
*/
attached: function() {
// Establish hax properties if they exist
let props = {
canScale: true,
canPosition: true,
canEditSource: false,

$ yarn run devTest
$ yarn run testBuild
Builds ensure that wcfactory can correctly compile your web component project to work on the maximum number of browsers possible.
$ yarn run buildDemo
Run yarn start will start a local development server, open your default browser to display it, open your finder to the correct window and start watching the /src directory for changes and automatically rebuilding the element and documentation site for the demo.
