Exploring Angular2 and TypeScript for the first time. Attempting examples like the one below:

  @Component({
  selector: 'counter',
  template: `
    {{ value }}
    <button (click)="increase()">Increase</button>
    <button (click)="decrease()">Decrease</button>
  `
  })
  class Counter {
    value: number;

    constructor() {
    this.value = 1;
    }

    increase() {
    this.value = this.value + 1;
    }

    decrease() {
    this.value = this.value - 1;
    }
} 

Encountering the "Cannot find name 'Component'" error during compilation.

Inquiring about the issue at hand. What steps should I take to resolve it?

Answer №1

In TypeScript, it is crucial to import necessary elements as the language won't recognize certain decorators without them. However, within Angular, you have the capability to provide these imports.

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

Additionally, don't forget to export your class in order to use it in other parts of your codebase.

export class Counter
