Dependencies

• Angular (requires Angular 2 or higher, tested with 2.0.0)
• Angular Material

Installation

Install above dependencies via npm.

Now install mat-progress-buttons via:

npm install --save mat-progress-buttons

---

SystemJS

Note:If you are using SystemJS, you should adjust your configuration to point to the UMD bundle. In your systemjs config file, map needs to tell the System loader where to look for mat-progress-buttons:

map: {
  'mat-progress-buttons': 'node_modules/mat-progress-buttons/bundles/mat-progress-buttons.umd.js',
}

---

Once installed you need to import the main module:

import { MatProgressButtonsModule } from 'mat-progress-buttons';

The only remaining part is to list the imported module in your application module. The exact method will be slightly different for the root (top-level) module for which you should end up with the code similar to (notice MatProgressButtonsModule .forRoot()):

import { MatProgressButtonsModule } from 'mat-progress-buttons';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [MatProgressButtonsModule.forRoot(), ...],  
  bootstrap: [AppComponent]
})
export class AppModule {
}

Other modules in your application can simply import MatProgressButtonsModule:

import { MatProgressButtonsModule } from 'mat-progress-buttons';

@NgModule({
  declarations: [OtherComponent, ...],
  imports: [MatProgressButtonsModule, ...], 
})
export class OtherModule {
}

Usage

Spinner Button

import { Component } from '@angular/core';
import { MatProgressButtonOptions } from 'mat-progress-buttons';

@Component({
  selector: 'app-home',
  template: '<mat-spinner-button (btnClick)="btnClick()" [options]="btnOpts"></mat-spinner-button>'
})
export class SomeComponent {

  // Button Options
  btnOpts: MatProgressButtonOptions = {
    active: false,
    text: 'Stroked Button',
    spinnerSize: 19,
    raised: false,
    stroked: true,
    flat: false,
    fab: false,
    buttonColor: 'accent',
    spinnerColor: 'accent',
    fullWidth: false,
    disabled: false,
    mode: 'indeterminate',
    customClass: 'some-class',
    // add an icon to the button
    buttonIcon: {
      fontSet: 'fa',
      fontIcon: 'fa-heart',
      inline: true
    }
  };

  // Click handler
  btnClick(): void {
    this.btnOpts.active = true;
    setTimeout(() => {
      this.btnOpts.active = false;
    }, 3350);
  }
};

Spinner button FAB

You can use the spinner button with a mat-fab with an icon. Both mat-icon and font awesome are supported.

To set up fontawesome to work with mat-icon you can see instructions here

Use the icon property on the options object

Note: Bar Button does not support the fab style, currently.

  btnOpts: MatProgressButtonOptions = {
    active: false,
    text: 'Stroked Button',
    spinnerSize: 19,
    raised: false,
    stroked: true,
    flat: false,
    fab: true, // set fab to true
    buttonColor: 'accent',
    spinnerColor: 'accent',
    fullWidth: false,
    disabled: false,
    mode: 'indeterminate',
    icon: {
      color: primary,
      fontSet: 'fa',
      fontIcon: 'fa-save',
      inline: true
    },
  };

Icon API

interface MatProgressButtonIcon {
  color?: ThemePalette; // icon color (primary or accent)
  fontIcon?: string;    // name of the icon (for fontawsome, use 'fa-[icon_name])'
  fontSet?: string;     // if using fontawesome, use 'fa' (omit for material icons)
  inline?: boolean;     // automatically size the icon
  svgIcon?: string;     // name of the icon in the SVG icon set.
}

Bar Button

import { Component } from '@angular/core';
import { MatProgressButtonOptions } from 'mat-progress-buttons';

@Component({
  selector: 'app-home',
  template: '<mat-bar-button (btnClick)="btnClick()" [options]="btnOpts"></mat-bar-button>'
})
export class SomeComponent {

  // Button Options
  btnOpts: MatProgressButtonOptions = {
    active: false,
    text: 'Stroked Button',
    buttonColor: 'accent',
    barColor: 'accent',
    raised: false,
    stroked: true,
    flat: false,
    mode: 'indeterminate',
    value: 0,
    disabled: false,
    customClass: 'some-class',
    // add an icon to the button
    buttonIcon: {
      fontSet: 'fa',
      fontIcon: 'fa-heart',
      inline: true
    }
  };

  // Click handler
  btnClick(): void {
    this.btnOpts = { ...this.btnOpts, active: true };
    setTimeout(() => {
      this.btnOpts = { ...this.btnOpts, active: false };
    }, 3350);
  }
};

Global Options

Optionally pass default MatProgressButtonOptions in forRoot in side your app.modlue.ts for each button as an array.

const button1: MatProgressButtonOptions = {
  id: 'button1', // Id should match the [buttonId] input
  ...
};

const button2: MatProgressButtonOptions = {
  id: 'button2', // Id should match the [buttonId] input
  ...
};

@NgModule({
  imports: [
    MatProgressButtonsModule.forRoot([button1, button2]),
  ],
  declarations: [HomeComponent],
})

NB: add the id above should match the id provided in the [buttonId] input.

<mat-bar-button
  (btnClick)="someFunc3()"
  [buttonId]="'button1'"
  [active]="buttonState"
></mat-bar-button>

[options] will override Global Options provided in forRoot

Overriding default CSS

To override CSS (color and background color of spinner buttons), you can write CSS for particular component and use ViewEncapsulation.None

Example:

CSS:

.class-name {
    background-color: red;
}

TS:

@Component({
  ...,
  encapsulation: ViewEncapsulation.None
})
class MyComponent {}
