The first release candidate of Angular 2 Material Design Lite (angular2-mdl) is out

angular 2 Material Design Lite

The first release candidate of my angular 2 component library has been released (demo github). This library provides components and directives that can be used in angular 2. The comppnents are based on material design lite (see for more information about this ui framework).

This post covers why i have written such a component library, how to use it and what components are offered by this npm module.

Update (08/24/2016): angualr2-mdl is finally released and supports now angular 2 (rc5) and material design lite version 1.2.

Why a component library for mdl

Material design lite was written as a collection of scss files and a little bit of javascript to add dynamic behavior like ripple effects, focus and blur handling and so on. It was not written with a specific javascript framework in mind. And it was also not written to match the needs of dynamic ui generation. So for example: you will not have the possibility to add menu items to a menu after the menu was created.

Until now there is no complete library for angular 2 that provides material design components. The official implementation Material Design components for Angular 2 is still in the alpha state.

That’s why i decided to write an implementation of material design components for angular 2 based on material design lite. After one month of work the npm package is now nearly feature complete and version 1.0.0-rc1 is released. For sure: any help/contribution is appreciated!

A side effect is that you don’t need to write a lot of css classes and html structures to create material design lite components.

Instead of

<div class="mdl-textfield mdl-js-textfield mdl-textfield--expandable">
    <label class="mdl-button mdl-js-button mdl-button--icon" for="sample6">
      <i class="material-icons">search</i>
    <div class="mdl-textfield__expandable-holder">
      <input class="mdl-textfield__input" type="text" id="sample6">

you just write:

<mdl-textfield type="text" [(ngModel)]="theText" icon="search"></mdl-textfield>

to create an expandle text field and get two-way-databindig for free!

How to use angular2-mdl

To get started you need to install the npm package and integrate it in your build system:

npm install angular2-mdl --save

I use angular cli with system.js as my build system. If you do the same, you have to do the following steps to integrate angular2-mdl in your project: 1. Extend the angular-cli-build.js file to include angular2-mdl as a vendor package:

return new Angular2App(defaults, {

  vendorNpmFiles: [

Next you need to configure your system-config.js file:

const map: any = {
  'angular2-mdl': 'vendor/angular2-mdl'

/** User packages configuration. */
const packages: any = {
  'angular2-mdl': { main: 'dist/components/index.js'}

After that you may use the angular2-mdl directives in your components:

import { MDL_DIRECTIVES } from 'angular2-mdl';

   directives: [ MDL_DIRECTIVES ]

You may include the material-deisgn-lite css in your html and you’re done!

<link rel="stylesheet" href="" />

Under you’ll find a customizing tool to change the theme colors.

But there is also another way. This package includes the scss files from material-design-lite. With these files you are able to change the colors and other variables in your own scss files:

First of all you need to install node-sass for your project:

npm install node-sass --save-dev

After that you need to configure the sass compiler to use the sass files from the angular2-mdl package. For that the file angular-cli-build.js needs to be extended:

return new Angular2App(defaults, {

    sassCompiler: {
      includePaths: [
    vendorNpmFiles: [

Now you can use the sass sources form angular-material-lite and change the used colors in your app:

@import "color-definitions";

$color-primary: $palette-blue-500;
$color-primary-dark: $palette-blue-700;
$color-accent: $palette-amber-A200;
$color-primary-contrast: $color-dark-contrast;
$color-accent-contrast: $color-dark-contrast;

@import 'material-design-lite';

Which components are available right now

The following components are included in the version 1.0.0-rc1:

  • Badges
  • Buttons
  • Cards
  • Icons
  • Loading
  • Shadow
  • Toggle (Checkbox, Radio, Icon Toggle, Switch)
  • Lists
  • Slider
  • Snackbar
  • Table
  • Tooltips
  • Menu
  • Layout (standard, scroll, waterfall, tabs)
  • Tabs
  • Textfields (multiline, expandable)

You’ll find demos and examples on how to use these components within the e2e test application

My next steps are: polish the api and components/directive selectors and extend the documentation.
