Migrating from lucide-angular ⇒ @lucide/angular

What changed

@lucide/angular moves from a module + single component based API to a more modern Angular approach:

• The library defines modern signal-based, standalone components, without zone.js based change detection.
• Icons are consumed as standalone imports (one component per icon).
• Dynamic icon registration is done via provideLucideIcons(), not using NgModule.
• Static icons use per-icon components for better tree-shaking.
• Dynamic icons still use a single dynamic component (svg[lucideIcon]).
• Global defaults are configured via provideLucideConfig().

Step 1 – Update dependencies

Remove lucide-angular, add @lucide/angular, see http://lucide.dev/guide/packages/angular#installation

Step 2 – Replace LucideAngularModule.pick(...) with provideLucideIcons(...)

Notes:

• Old imports like AirVentIcon / AlarmClock from lucide-angular should be replaced with the new per-icon exports LucideAirVent and LucideAlarmClock.
• If you mostly used static icons, you may not need to provide them at all, please refer to Step 3.

Before

NgModule based

import { BrowserModule, NgModule } from '@angular/core';
import { LucideAngularModule, AirVent, AlarmClock } from 'lucide-angular';

@NgModule({
  imports: [
    BrowserModule,
    LucideAngularModule.pick({ AirVent, AlarmClock }),
  ],
})
export class AppModule {}

Standalone

import { ApplicationConfig } from '@angular/core';
import { LucideAngularModule, AirVent, AlarmClock } from 'lucide-angular';

export const appConfig: ApplicationConfig = {
  providers: [
    // ...
    importProvidersFrom(LucideAngularModule.pick({ AirVent, AlarmClock })),
  ]
};

After

import { ApplicationConfig } from '@angular/core';
import { provideLucideIcons, LucideAirVent, LucideAlarmClock } from '@lucide/angular';

export const appConfig: ApplicationConfig = {
  providers: [
    // ...
    provideLucideIcons(
      LucideAirVent,
      LucideAlarmClock,
    ),
  ]
};

Step 3 – Replace <lucide-angular> / <lucide-icon> / <i-lucide> / <span-lucide>

The legacy package rendered everything through a single component. All of these selectors must be migrated to <svg> usage.

A. Static icons by name

If the icon is known at build time, just use a static import:

Before

<lucide-angular name="circle-check"></lucide-angular>

After

<svg lucideCircleCheck></svg>

B. Static icons with icon data binding

Before

import { CircleCheck } from 'lucide-angular';

<lucide-icon [img]="CircleCheck"></lucide-icon>

After

import { LucideCircleCheck } from '@lucide/angular';

<svg lucideCircleCheck></svg>

...and import LucideCircleCheck from @lucide/angular.

C. Dynamic icons

If the icon varies at runtime, use the dynamic component:

Before

<lucide-icon [name]="item.icon"></lucide-icon>

After

<svg [lucideIcon]="item.icon"></svg>

Step 4 – Replace LucideIconConfig with provideLucideConfig()

Before

import { inject } from '@angular/core';
import { LucideIconConfig } from 'lucide-angular';

inject(LucideIconConfig).size = 12;

After

import { provideLucideConfig } from '@lucide/angular';

providers: [
  provideLucideConfig({ size: 12 }),
]

Where to place it

• App-wide: AppModule.providers or bootstrapApplication(...providers)
• Feature-level: feature module providers
• Component-level (standalone): component providers

Troubleshooting

The icon is not being displayed

If using per-icon-components:

1. Ensure that the icon component is being imported, if using per-icon-components
2. Check that the icon name matches exactly (case-sensitive)

If using the dynamic component:

1. Ensure the icon is provided via provideLucideIcons() if using string names
2. Verify the icon is imported from @lucide/angular and not the legacy package

TypeScript errors?

Make sure you're importing from @lucide/angular and not lucide-angular.

Icons render with wrong defaults

Ensure provideLucideConfig() is used at the right level.

TL;DR

• LucideAngularModule ⇒ static: removed; dynamic: LucideIcon
• LucideAngularModule.pick(...) ⇒ provideLucideIcons(...)
• <lucide-angular name="foo-bar"> ⇒ <svg lucideFooBar>
• <lucide-icon [name]="expr"> ⇒ <svg [lucideIcon]="expr">
• <lucide-icon [img]="expr"> ⇒ <svg [lucideIcon]="expr">
• LucideIconConfig ⇒ provideLucideConfig(...)
