Usage

Standalone Components

import { BiComponent, provideBi, withIcons, exclamationOctagonFill, xCircleFill } from 'dfx-bootstrap-icons';

@Component({
  standalone: true,
  selector: 'app-root',
  template: ` <bi name="exclamation-octagon-fill" /> `,
  imports: [BiComponent],
  providers: [provideBi(withIcons({ exclamationOctagonFill, xCircleFill }))],
})
export class AppComponent {}

Module

import { BiModule, withIcons, exclamationOctagonFill } from 'dfx-bootstrap-icons';

@NgModule({
  declaration: [AppComponent],
  imports: [BiModule.setup(withIcons({ exclamationOctagonFill }))],
})
export class AppModule {}

@Component({
  selector: 'app-root',
  template: ` <bi name="exclamation-octagon-fill" /> `,
})
export class AppComponent {}

Configuration

Standalone Components

import { provideBi, BiComponent, withIcons, withWidth, withHeight, withColor, exclamationOctagonFill } from 'dfx-bootstrap-icons';

@Component({
  // ...
  standalone: true,
  imports: [BiComponent],
  providers: [provideBi(withIcons({ exclamationOctagonFill }), withWidth(16), withHeight(16), withColor('currentColor'))],
  template: ` <bi name="exclamation-octagon-fill" /> `,
  // ...
})
export class AppComponent {}

Module

import { BiModule, withIcons, withWidth, withHeight, withColor, exclamationOctagonFill } from 'dfx-bootstrap-icons';

@NgModule({
  declaration: [AppComponent],
  imports: [BiModule.setup(withIcons({ exclamationOctagonFill }), withWidth(16), withHeight(16), withColor('currentColor'))],
})
export class AppModule {}

Configuration parameters

Component

@Component({
  // ...
  selector: 'app-root',
  template: ` <bi name="exclamation-octagon-fill" width="16" height="16" color="currentColor" clearDimensions="false" ariaLabel="Icon" /> `,
  // ...
})
export class AppComponent {}

Parameters

Width, height and size??

BiComponent picks the size for the icon in the following order based on which params you inject and pass.

const width = Input_Size ?? Input_Width ?? Injected_Size ?? Injected_Width;
const height = Input_Size ?? Input_Height ?? Injected_Size ?? Injected_Height;

CDN

You are not required to include every used icon in your bundle. Instead, you have the option to utilize a CDN URL, allowing you to load your icons dynamically at runtime, either exclusively or in addition to bundling them.

When providing multiple URLs, dfx-bootstrap-icons is going to pick a single one randomly at app start.

Configure a pool of CDN URLs:

import { provideBi, withCDN } from 'dfx-bootstrap-icons';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withCDN('https://playground.dafnik.me/bootstrap-icons/icons'))],
}).catch((err) => console.error(err));

Don't forget to add the HttpClient and biCacheInterceptor

HttpClient Interceptor

When using CDNs you can use the biCacheInterceptor to prevent the duplicate fetching of icons.

import { biCacheInterceptor } from 'dfx-bootstrap-icons';
import { provideHttpClient, withInterceptors } from '@angular/common/http';

bootstrapApplication(AppComponent, {
  providers: [provideHttpClient(withInterceptors([biCacheInterceptor]))],
}).catch((err) => console.error(err));

Using your assets folder as the CDN

You can bundle all icons into your assets folder so they will be included in your bundle but not get loaded unless you use actually them.

// main.ts

import { provideBi, withCDN } from 'dfx-bootstrap-icons';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withCDN('/assets/bootstrap-icons'))],
}).catch((err) => console.error(err));

// angular.json, project.json or nx.json

{
  "options": {
    "assets": [
      {
        "glob": "*",
        "input": "node_modules/dfx-bootstrap-icons/icons",
        "output": "/assets/bootstrap-icons"
      }
    ]
  }
}

Examples

Provide imported icons application wide

// icons.ts

import {
  apple,
  // Import more icons
} from 'dfx-bootstrap-icons';

export const ICONS = {
  apple,
  // Import more icons
};

// main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { provideBi, withIcons } from 'dfx-bootstrap-icons';
import { AppComponent } from './app/app.component';
import { ICONS } from './app/icons.ts';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withIcons(ICONS))],
}).catch((err) => console.error(err));

Import all icons (not recommended)

import { provideBi, withIcons, allIcons } from 'dfx-bootstrap-icons';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withIcons(allIcons))],
}).catch((err) => console.error(err));
