angular material icons example

Angular newbie here..could someone direct me to the right way how could I replace the existing Material icons with custom ones properly, more precisely with the SVG graphics? Something like this:

So this:

<mat-icon class="mat-icon-rtl-mirror">
     {{nestedTreeControl.isExpanded(node) ? 'expand_more' : 'chevron_right'}}

With this:

<mat-icon class="mat-icon-rtl-mirror">
     {{nestedTreeControl.isExpanded(node) ? 'INSERT_SVG_1_HERE' : 'INSERT_SVG_2_HERE'}}

Unfotunatley this does not exactly solve your problem, because you will need to use the argument svgIcon on the mat-icon element instead of using the innerText of mat-icon but otherwise it works:

  1. You have to allow to angular to import from svg's by declaring the module.
  2. To import/inline the icons into javascript, you will have to override the loader. This can be achieved through using the raw-loader.
  3. Now you will be able to import the svg into angular and register them through the MatIconRegistry;

As an example:

// src/typings.d.ts

declare module '*.svg' {
  const svg: string;
  export default svg;
// src/app/app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { DomSanitizer } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { MatIconModule, MatIconRegistry } from '@angular/material';

import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

import thumbsUp from '!!raw-loader!./thumbs-up.svg';

  imports:      [ 
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
export class AppModule {
  constructor(iconRegistry: MatIconRegistry, sanitizer: DomSanitizer) {
        'thumbsUp', sanitizer.bypassSecurityTrustHtml(thumbsUp));
// src/app/app.component.html
<mat-icon svgIcon="thumbsUp"></mat-icon>
// src/app/thumbs-up.svg

Another approach would be to install @mdi/svg

npm install @mdi/svg

and then follow the steps above, with the difference to import each necessary icon as well, e.g. expand_more and chevron_right

so in src/app/app.module.ts

// src/app/app.module.ts
import expandMore from '!!raw-loader!@mdi/svg/svg/chevron-down.svg';
import chevronRight from '!!raw-loader!@mdi/svg/svg/chevron-right.svg';
export class WeddingDayModule {
    private iconRegistry: MatIconRegistry,
    private sanitizer: DomSanitizer
  ) {
      .addSvgIconLiteral('chevron_right', sanitizer.bypassSecurityTrustHtml(chevronRight))
      .addSvgIconLiteral('expand_more', sanitizer.bypassSecurityTrustHtml(expandMore));

And in the html just as a simplification... but you will get the idea...

<mat-icon [svgIcon]="expanded ? 'chevron_right' : 'expand_more'" (click)="expanded = !expanded"></mat-icon>

the down side with this approach is, that you will have to register all the icons you want to use... But at least you stay in the same domain of change. Instead of using the ligatures you can change them all through the svgIcon and you get more icons than just the icons the outdated material-design-icons library holds.

I hope that helps

  • Yes I'm aware of that approach and I managed to use it as an svgIcon on mat-icon… However I'm trying to find a way to replace 'expand_more' : 'chevron_right' with custom SVG-s, so it could be used in conditionals etc… Don't know if it's possible at all? Thanks for the effort, will award it when it's enabled
  • So if I understand correctly, the implementation you want to achieve is to find a consistent way of either using a custom svg icon or a defaultish material icon?
  • yes correct - so if I have custom let's say US-flag SVG graphic, I would like to be able to use it as 'us_flag_custom' anytime I need it
  • Okay, so how about to turn it the other way around and use e.g. @mdi/svg, and then import the material icons as mentioned above. Then they can at least be used consistently as svgIcon's. Not perfect as you would have to register each material icon that you want to use... If you think that would solve the problem, I'll update the answer
  • @Smithy btw, just figured, you can mix it without problem. <mat-icon [svgIcon]="icon">{{ icon }}</mat-icon>, if no ligature is available, the svgIcon is taken.
  • It does not seem to work like that…shows only '../folder' if I insert it like '../assets/SVG_file.svg'
