What are standalone components?

Q: What are standalone components?

**Core concept.** A standalone component (also directive/pipe) sets standalone: true and declares its **own imports ** — so it doesn't need to be declared in an @NgModule . You bootstrap a standalone app with bootstrapApplication(AppComponent) . Since Angular 17+ standalone is the **default** for new projects. standalone: true imports: [CommonModule, ...] CommonModule <text class='d-sub' x='230' y='131'

A standalone component + bootstrap

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { bootstrapApplication } from '@angular/platform-browser';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule],                 // declares its OWN dependencies
  template: `
    <ul><li *ngFor="let t of todos">{{ t }}</li></ul>
  `,
})
export class AppComponent {
  todos = ['Learn standalone', 'Drop NgModules'];
}

// No AppModule needed:
bootstrapApplication(AppComponent);
