This article will give you example of angular 10 global variable for all components. i would like to share with you global variable in angular 10. This post will give you simple example of dynamic global variable in angular 10. This tutorial will give you simple example of angular 10 access global variable. you will do the following things for angular global constants.

We always need to declare global variable file for our angular 10 application because we can set some global variable there like site title, api url etc so you can easily access any where in our application easily.

So, in this example, we will create GlobalConstants file for adding global variables in our application. in that file i added two variables as apiURL and siteTitle. I will access those variable value in my AppComponent file. you can also access all the component as you want.

Now, bellow we will create GlobalConstants as like created bellow and We will use that variables as like used in AppComponent file.

src/app/common/global-constants.ts

export class GlobalConstants {

public static apiURL: string = "https://itsolutionstuff.com/";

public static siteTitle: string = "This is example of ItSolutionStuff.com";

}

src/app/app.component.ts

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

import{ GlobalConstants } from './common/global-constants';

@Component({

selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css']

})

export class AppComponent implements OnInit{

title = GlobalConstants.siteTitle;

constructor() {

console.log(GlobalConstants.apiURL);

}

ngOnInit() {

console.log(this.title);

}

}

Now you can check this project and run it.

It will display as like bellow:

Output:
