Installation

npm install lit @ircam/simple-components --save

Note: this library has never been tested with other framework than lit, any feedback is welcome.

Since v2, this package has moved to lit@2, which might cause issues if your application is using lit-html@1.x.x and/or lit-element@1.x.x
to update your app, see: https://lit.dev/docs/releases/upgrade/
if you don't want to update your app now, please fall back to version 1.x.x `npm install --save @ircam/simple-components@1.3.0`

Usage

Each components lives in its own file and should be imported separately, e.g.

import '@babel/polyfill';
import { html, render } from 'lit/html.js';
import '@ircam/simple-components/sc-toggle.js'

render(html`
  <sc-toggle
    @change="${e => console.log(e)}"
  ></sc-toggle>
`, document.body);

Support older browsers

To support older browser, you should import webcomponentsjs/webcomponents-bundle.js and ./vendors/lit/polyfill-support.js

A possible solution is to copy the file from your node_modules folder into a directory exposed by your server using postinstall scripts

In package.json

"scripts": {
  "postinstall": "mkdir -p ./vendors && cp -R node_modules/@webcomponents/webcomponentsjs ./vendors/ && cp -R node_modules/lit ./vendors/",
}

<script defer src="./vendors/webcomponentsjs/webcomponents-bundle.js"></script>
<script defer src="./vendors/lit/polyfill-support.js"></script>

Such strategy as been implemented in the docs directory.

Design Considerations

These design aspects aim at simplifying future wrapping of the components in an editing tool.

Attributes

All components must expose a width and height attribute, for squared components (e.g. <sc-bang> and <sc-toggle>) the last attribute set wins

Events

all components should at least expose an @input or a @change event.
they can expose additional events, e.g. button @press and @release
payload should always have e.details.value

@todos

new elements

<sc-range>
<sc-multislider>
<sc-volume> (slider and number w/ db and lin output)
<sc-pan>
<sc-select>
<sc-radio>
<sc-dial> (maybe we just have to accept some people like that sort of thing...)
