@anywhichway/quick-component v0.0.15

quick-component

A small utility for rapidly creating remotely loadable, on-demand, isolatable web components

Script Tag Usage

The easiest way to use @anywhichway/quick-component is to load both it and the component it is using from a CDN, e.g.

<script src="https://cdn.jsdelivr.net/npm/@anywhichway/quick-component.j" 
        component="https://cdn.jsdelivr.net/npm/@anywhichway/repl-host@0.0.14"></script>

If you are using JSDelivr, by default the tag name will be the file or terminal directory name of the component without a version number. Component versioning is currently only supported for JSDeliver.

You can provide an alternate tag with the 'as' attribute:

<script src="https://cdn.jsdelivr.net/npm/@anywhichway/quick-component.js@0.0.5" 
        component="https://cdn.jsdelivr.net/npm/@anywhichway/repl-host@0.0.3" 
        as="hosted-repl"></script>

These additional attributes are available:

import - An array of CSS selectors that allow importing component elements into the head of the requesting document. This is sometimes necessary to support styling or JavaScript libraries that were not necessarily designed to run in a shadowDOM. If import is not specified it defaults to ["link","style","script"].

isolate - Takes the value "true" or "false". The value "true" places the actual contents of the component into an iframe and creates a proxy around the iframe to support automatic resizing.

If isolate is "true", you can configure the iframe security using the same attributes used by an iframe, i.e. allow, allowfullscren, allowpaymentrequest, referrerpolicy, csp, sandbox. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe.
