mwc-snackbar

:warning: These components are a work in progress. They are pre-release and should be considered experimental, as they may undergo major changes before release. We are experimenting with alternate architectures and approaches with the goal of allowing us to bring the most correct and optimal implementation of Material components to the widest possible audiences. Visible progress may be slow, as this research is across teams and repositories so is not consistently reflected in commits to this codebase. :warning:

Getting started

• The easiest way to try out mwc-snackbar is to use one of these online tools:

  • Runs in all supported browsers: StackBlitz, Glitch

  • Runs in browsers with JavaScript Modules: JSBin, CodePen.

• You can also copy this HTML file into a local file and run it in any browser that supports JavaScript Modules.

• When you're ready to use mwc-snackbar 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-snackbar to your project:

     npm i @material/mwc-snackbar

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

     <script type="module" src="@material/mwc-snackbar/index.js"></script>

     Or into your module script:

     import {Snackbar} from "@material/mwc-snackbar"

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

     <mwc-snackbar></mwc-snackbar>

  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-snackbar 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-snackbar 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-snackbar.

Supported Browsers
