mwc-formfield

A Material Components formfield implementation using Web Components

Getting started

• When you're ready to use mwc-formfield in a project, install it via npm. To run the project in the browser, a module-compatible toolctain is required. We recommend installing the Polymer CLI and using its development server as follows.

  1. Ensure the webcomponents polyfills are included in your HTML page

     • Install webcomponents polyfills

       npm i @webcomponents/webcomponentsjs

     • Add webcomponents polyfills to your HTML page

       <script src="@webcomponents/webcomponentsjs/webcomponents-loader.js"></script>

  2. Add mwc-formfield to your project:

     npm i @authentic/mwc-formfield

  3. Import the mwc-formfield definition into your HTML page:

     <script type="module" src="@authentic/mwc-formfield/mwc-formfield.js"></script>

     Or into your module script:

     import { Formfield } from "@authentic/mwc-formfield"

  4. Create an instance of mwc-formfield in your HTML page, or via any framework that supports rendering Custom Elements:

     <mwc-formfield></mwc-formfield>

  5. Install the Polymer CLI:

     npm i -g polymer-cli

  6. Run the development server and open a browser pointing to its URL:

     polymer serve

  mwc-formfield is published on npm using JavaScript Modules. This means it can take advantage of the standard native JavaScript module loader available in all current major browsers.

  However, since mwc-formfield uses npm convention to reference dependencies by name, a light transform to rewrite specifiers to URLs is required to get it to run in the browser. The polymer-cli's development server polymer serve automatically handles this transform.

  Tools like WebPack and Rollup can also be used to serve and/or bundle mwc-formfield.
