Angular material switch between mat-icon-button and mat-button

Question

Is there any prettier way to switch between mat-icon-button and mat-button, depending on media queries? I've made a demo of my current solution, but it needs two independent button.

<button type=button mat-icon-button fxHide fxShow.lt-sm (click)="onEdit($event)">
  <mat-icon>edit</mat-icon>
</button>
<button type="button" mat-button fxHide.lt-sm (click)="onEdit($event)">
  <mat-icon>edit</mat-icon> Edit
</button>

Got the same problem, currently using this solution.

Component.html:

<button
        mat-button
        [ngClass]="isBigDevice() ? 'mat-stroked-button' : 'mat-icon-button'"
        color="accent"
        type="button"
        (click)="coolMethodToDoStuff()"
        [disabled]="isSelected() && contextTypeIsSomething()">
    <span *ngIf="isBigDevice()">Edit</span>
    <mat-icon *ngIf="!isBigDevice()">edit</mat-icon>
</button>

There is a problem/annotation: You need to add the base button style/property mat-button. If you dont, you will get an error that color is no property for this kind of html-element. The advantages are, if you have multiple properties on one button or conditions for disabled, hidden or *ngIf you dont need them twice. I know with *ngIfthe readability is lacking, but currently its the best way to avoid a huge junk of duplicate code.

Next step for me: I will build an directive for things like this.

Edit:

More over this is my MediaQueryService:

import {Injectable, OnDestroy} from '@angular/core';
import {BreakpointObserver, Breakpoints, BreakpointState} from '@angular/cdk/layout';
import {Subject} from 'rxjs';
import {takeUntil} from 'rxjs/operators';

@Injectable({
    providedIn: 'root'
})

export class MediaQueryService implements OnDestroy {

private _breakpointArray = {
    isXSmall: false,
    isSmall: false,
    isMedium: false,
    isLarge: false,
    isXLarge: false,
};
private _destroy$ = new Subject();

constructor(
    private _breakpointObserver: BreakpointObserver,
) {
    this._breakpointObserver
        .observe([
            Breakpoints.WebLandscape,
            Breakpoints.WebPortrait,
        ])
        .pipe(
            takeUntil(this._destroy$)
        )
        .subscribe((state: BreakpointState) => {
            _breakpointObserver.isMatched(Breakpoints.WebLandscape)
                ? this.webOrientationChangeLogger('landscape')
                : this.webOrientationChangeLogger('portrait');
        });

    this._breakpointObserver.observe([
            Breakpoints.XSmall,
            Breakpoints.Small,
            Breakpoints.Medium,
            Breakpoints.Large,
            Breakpoints.XLarge,
        ]
    )
        .pipe(
            takeUntil(this._destroy$)
        )
        .subscribe((state: BreakpointState) => {
            this._breakpointArray.isXSmall = _breakpointObserver.isMatched(Breakpoints.XSmall);
            this._breakpointArray.isSmall = _breakpointObserver.isMatched(Breakpoints.Small);
            this._breakpointArray.isMedium = _breakpointObserver.isMatched(Breakpoints.Medium);
            this._breakpointArray.isLarge = _breakpointObserver.isMatched(Breakpoints.Large);
            this._breakpointArray.isXLarge = _breakpointObserver.isMatched(Breakpoints.XLarge);
        });
}

public ngOnDestroy(): void {
    this._destroy$.next();
    this._destroy$.complete();
}

public get isSmallDevice(): boolean {
    return this.getBreakpointBoolean('isXSmall') || this.getBreakpointBoolean('isSmall');
}

public get isBigDevice(): boolean {
    return this.getBreakpointBoolean('isXLarge') || this.getBreakpointBoolean('isLarge');
}

public getBreakpointBoolean(breakpointName: string): boolean {
    return this._breakpointArray[breakpointName];
}

private webOrientationChangeLogger(orientation: string) {
    console.log(orientation);
}

}

And inside the component where I am using the button I just call the isBigDevice() method and return the boolean.

Component.ts:

public isBigDevice(): boolean {
    return this._mediaQueryService.isBigDevice();
}

You could also try use this the fxShow, fxHide properties of angular material.
