Angular 4 Display Current Time

Have you ever wondered how to display the current time using Angular 4? Well, you're in luck! In this article, we'll walk you through a simple guide on how to achieve this using Angular 4. So, grab your coding tools and let's get started!

To begin with, we need to create a new Angular component where we'll implement the logic to display the current time. Let's name our component 'current-time'.

Within the component, we first import the necessary modules. We'll require the 'Component' decorator from '@angular/core' and set up our component shell. Here's a snippet to get you started:

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

@Component({
  selector: 'app-current-time',
  template: `
    <div>
      <p>Current Time: {{ currentTime }}</p>
    </div>
  `
})
export class CurrentTimeComponent {

  currentTime: string;

  constructor() {
    this.getCurrentTime();
    setInterval(() =&gt; {
      this.getCurrentTime();
    }, 1000);
  }

  getCurrentTime() {
    const date = new Date();
    this.currentTime = date.toLocaleTimeString();
  }
}

Inside the component class, we have a property 'currentTime' which will hold the current time value. In the constructor, we call the 'getCurrentTime()' method to get the initial time value. We then use the 'setInterval()' function to update the time every second.

The 'getCurrentTime()' method creates a new Date object and assigns the current time in a human-readable format to the 'currentTime' property using 'toLocaleTimeString()' function.

Next, let's make sure to include our newly created component in the app module. Open up your 'app.module.ts' file and import the 'CurrentTimeComponent'. Add it to the 'declarations' array to ensure Angular recognizes our component.

import { CurrentTimeComponent } from './current-time.component';

@NgModule({
  declarations: [
    CurrentTimeComponent
  ],
  ...
})
export class AppModule { }

Finally, to display the 'current-time' component on our main app component template, open up the 'app.component.html' file and include the selector for the 'current-time' component.

That's it! You've successfully created a component that displays the current time using Angular 4. When you run your Angular application, you should now see the current time updating every second on the screen.

Keep in mind that this is a basic implementation. You can further enhance the functionality by customizing the time format, adding styling, or integrating with other features based on your requirements. Happy coding!
