Create components with typed inputs and clean templates.

Intermediate 13 min read Lesson 2 of 300 Challenge included

What you will be able to do

Use @Component with a template or templateUrl.
Declare typed @Input values.
Keep templates free of complex logic.
Use standalone imports for dependencies.

In plain English

A component owns a template and a class. Use @Input to receive data and keep the template declarative. Standalone components import what they need instead of relying on a module.

      <p>{{ minutes }} minutes</p>

  `,

  @Input({ required: true }) title!: string
