Why Standalone Components?

Standalone components let you build Angular apps without NgModules. A component declares its own dependencies, making the building blocks self-contained and easier to understand.

The NgModule Era

Traditionally every component, directive, and pipe had to be declared inside an @NgModule. Modules grouped declarations and managed imports/exports.

This added boilerplate and an extra layer of indirection.

Problems NgModules Caused

NgModules introduced common friction: forgetting to declare a component, declaring it in two modules, confusing imports vs declarations, and large shared modules that pulled in too much.

The Standalone Idea

With standalone components, each component lists exactly what it needs via its own imports array. There is no central module that must know about it.

import { Component } from '@angular/core';

@Component({
  selector: 'app-hello',
  standalone: true,
  template: '<p>Hello</p>'
})
export class HelloComponent {}

Self-Contained Dependencies

Because a standalone component declares its own dependencies, you can read a single file and know everything it relies on. This improves clarity and tooling.

Less Boilerplate

No more matching declarations and exports across modules. You import a component directly where you use it, similar to how ES modules work.

Better Tree-Shaking

Standalone components make the dependency graph explicit, which helps bundlers remove unused code and can lead to smaller bundles.

Lazy Loading Made Simple

Routes can lazily load a standalone component directly with a dynamic import, without needing a feature module wrapper.

// route: loadComponent: () => import('./page.component').then(m => m.PageComponent)

The New Default

In recent Angular versions, standalone is the default for newly generated components. NgModules still work, but standalone is the recommended path forward.

Interop with NgModules

Standalone and module-based code interoperate. A standalone component can be imported into an NgModule, and an NgModule-based component can use standalone imports, easing migration.

What You Still Configure

Application-wide setup (like the router or HTTP client) is provided through bootstrapApplication providers instead of a root module, which you will see later.

Recap: Why Standalone

Standalone components eliminate the NgModule boilerplate by letting each component declare its own dependencies. This brings clearer code, easier lazy loading, and better tree-shaking. Standalone is now the default. Next: creating one.
