How to deploy an Angular application to GitHub

In this article, we will follow a step-by-step approach to deploy an Angular application to a GitHub. We will create a project using Angular CLI  and then deploy that to GitHub. Let us get started.

Step 1

To create a project using Angular CLI. Run the command:

ng new demo

 You need to make sure that Angular CLI is installed globally on your machine.

Step 2

Change directory to demo and open project in VS Code or any other IDE of your choice.  Modify AppComponent to add, subtract, multiply, and divide two numbers as shown in the below listing:

export class AppComponent {
    title = 'Calculator App';
    num1: number;
    num2: number;
    result: number;
    add() {
        this.result = this.num1 + this.num2;
    }
    substract() {
        this.result = this.num1 - this.num2;
    }
    multiply() {
        this.result = this.num1 * this.num2;
    }
    divide() {
        this.result = this.num1 % this.num2;
    }
 
}

As you can see, that AppComponent is very simple and it contains code to perform basic calculator operations.

Next, modify the AppComponent template

<div class="container">    <br />    <div class="row">        <h1>            Welcome to {{ title }}!
        </h1>    </div>    <br />    <div class="row">        <div class="col-md-6">            <input type="number" [(ngModel)]="num1" placeholder="Enter Number 1" class="form-control" />        </div>        <div class="col-md-6">            <input type="number" [(ngModel)]="num2" placeholder="Enter Number 2" class="form-control" />        </div>    </div>    <br />    <div class="row text-center">        <div class="col-md-3">            <button class="btn btn-info" (click)='add()'>Add</button>        </div>        <div class="col-md-3">            <button class="btn btn-info" (click)='substract()'>Substract</button>        </div>        <div class="col-md-3">            <button class="btn btn-info" (click)='multiply()'>Multiply</button>        </div>        <div class="col-md-3">            <button class="btn btn-info" (click)='divide()'>Divide</button>        </div>    </div>    <br />    <div class="row">        <div class="col-md-5 col-md-offset-4">            <h2>Result = {{result}} </h2>        </div>    </div></div>

Like the component class template, it is also very simple. It uses:

  • ngModel for two way data binding between input controls and properties
  • event binding to call a function on click of the button
  • interpolation to display the result

Step 3

 Before we publish this application to GitHub, let us run it locally. To run it locally, run the command

ng serve

Your application should run on default port 4200 of localhost as shown in the image below:

Step 4

To deploy Angular application first create a repository on GitHub. To do that navigate to https://github.com/ and click on New Repository.  I am creating a repository named  “demo9“.  

 After the repository is created, use git command to add this repository as remote to the local project. For that run command as below :

git remote add origin https://github.com/USERNAME/PROJECT_NAME.git

Do not forget to change username and project name. Once the remote repository is added, you can verify that using the command

git remote -v

As output, you should get repository listed as below:

Step 5

To deploy the Angular application to GitHub, you need to first install the angular-cli-ghpages globally:

 npm install -g angular-cli-ghpages

 After installing that ghpages, use Angular CLI to build the project. For that run command as shown below:

ng build --prod --base-href https://debugmodedotnet.github.io/demo9/

Make sure that you are using your GitHub user name and repository name.  After successful execution of the command, you should get bundle.js created as shown in the image below: 

As the last step, run command ngh –no-silent to publish the application as shown in the image below:

After successful publish navigate to  https://<username>.github.io/<reponame>/ to navigate to the application.  This is all you need to do to deploy the Angular application to GitHub.
