Angular Lazy Loaded SVG Icons Library with Material Icons

Use the cool icons from Material in your app, fully tree-shaked and only loaded when necessary. Injected into the dom, and therefore IE compatible.

Deprecated!

Unfortunately material icons are not provided in a nice format that we can parse into a library anymore. Therefore I'm deprecating this library. Just use the official: https://material.angular.io/components/icon/overview

Live Demo

The live demo can be found at https://material-icons.akehir.com.

Getting Started

If you just want to use the library, follow the following 4 simple steps. For contributing, or building the library locally, see the section on building the library.

Supported Angular Versions | Angular Version | Library Version | | --------------- | ------------------------ | | 9.x | 1.0.0 | | 10.x | 2.0.0 | | 11.x | 3.0.0 | | 12.x | 4.0.0 | | 13.x | 5.0.3 |

Step 1: Install

Install the npm package.

npm i @triangular/material-icons

Step 2: Add to NgModule Imports

Then, add the MaterialIconsModule to the imports of your module(s).

import { NgModule } from '@angular/core';
import { MaterialIconsModule } from '@triangular/material-icons';

@NgModule({
    declarations: [
    ],
    imports: [
      MaterialIconsModule,
    ],
    providers: [],
    bootstrap: [],
})
export class AppModule { }

Step 3: Register the Icons in the Registry

The tree-shaking magic happens when you import icons from @triangular/material-icons/icons and register them in the MaterialIconsRegistry. By explicitly importing the icons where they are required, the tree shaking can ensure they are loaded when they are needed. If an icon is not required, it will not be bundled in your application. If an icon is required in a feature module, it will be bundled with the feature module. And if the icon is bundled in multiple feature modules, it will be bundled with the common bundle - in order to not download the same icon multiple times.

import { Component } from '@angular/core';
import { MaterialIconsRegistry } from '@triangular/material-icons';
import {
  materialIconAnkh,
  // add more icons here
} from '@triangular/material-icons/icons';

@Component({
  selector: 'app-some-component-with-icons',
  template: '<material-icon name="ankh"></material-icon>',
  styles: 'svg { color: #ccc; fill: currentColor; width: 5rem; height: 5rem; }',
})
export class SomeComponentWithIcons {

  constructor(private registry: MaterialIconsRegistry) {
    registry.registerIcons([
      materialIconAnkh,
      // add more icons here
    ]);
  }
}

Step 4: Enjoy using the Icons with a Peace of Mind

Once an icon has been registered, it can simply be used in your template. If you get the error can't bind to 'name' since it isn't a known property of 'material-icon', you need to include the MaterialIconsModule in your module.

<material-icon name="ankh"></material-icon>

Building

As a pre-requisite to build the library, you need to install all the dependencies via npm install or yarn. Furthermore, you will need to sync the projects submodules git submodule sync --recursive and git submodule update --init --recursive.

Building the Library

Before the sample app can be run, you need to build the library itself.

npm run build:lib

Building the Sample App

After building the library, it is either possible to build the sample app, via

npm run build:app

,or to run the sample app with a local dev server:

npm run start:app

Checking the bundle of the Sample App

You can verify how the application is bundled with the following command:

npm run analyze

Running the tests

Unit Tests

There are not many tests, but those that are can be run with:

npm run test -- --no-watch --progress=false --code-coverage --browsers ChromeHeadless

And coding style tests

The project follows the angular style guide and lints with the following command:

npm run lint
