Automate Angular Application Deployment via AWS CodePipeline - 👨🏻‍💻 👷🏻

In this article, I will show how to automate your deployment of the angular app to AWS S3 service by creating a pipeline on AWS Codepipeline service or in short we will do CI/CD for an angular project. In Case, you are wondering what are these AWS services,

AWS Codepipeline

AWS CodePipeline is a fully managed continuous delivery service that helps you automate your release pipelines for fast and reliable applications. Read more here


Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. Read more here.

As this article is more focused on automating deployment I will not discuss these AWS services in detail. So, enough talk, let's see it practically, which I had break-in steps.

So the first step is,

1) Create an Angular Project

Most of the time, you probably have a project which you want to deploy, but if you just want to play with it you obviously have to create it by typing in the command prompt:

ng new angular-aws-app
Enter fullscreen mode Exit fullscreen mode

where angular-aws-app will be your app name.

Now after successfully creating your project, go to and create a repository for your app and push your code to your repo master branch.

2) Create Pipeline on AWS Code-Pipeline service

After pushing your initial code on Github, we need to create a pipeline or an automated process that will be responsible for deploying our code to Amazon S3 from Github repo. But for this, you will need an AWS account so that you can access their services. Here you can create your account for free tier which will be free for 365 days. After creating your account you will see a dashboard console.

Alt Text
Type code pipeline and click to that service and go to pipelines in the sidebar to create a new pipeline for our app. You'll see an orange button on the top right corner to create a new pipeline.

Alt Text
First, we set up our pipeline name to ng-app-pipeline and select New Service Role for setup role service as it is our new brand pipeline. After setting the pipeline name, click next for the next step.

Alt Text
In step 2 of pipeline creation, we have to provide our source control from where it will get our code to build and deploy to s3. In our case, we will select Github as we pushed our code to Github. After selecting Github, click on the Connect to Github button and provide your repository with its production branch which is usually master for most of us and click next for the next step.

Now in Add Build Stage step, we have to provide which service we are using for creating a staging build, so we have selected AWS CodeBuild service which is a service for AWS, you can select Jenkins if you are using it. Select your region and create new project for it. A new window will open and you will provide details of your build project.

In project configuration,

provide a project name for your build project. It could be any name you want.

In Environment,

Select the
operating system: ubuntu,
Runtime: Standard,
Image: aws/codebuild/standard:1.0,
Image Version: always use latest image for this runtime version,

Now click on Continue to CodePipeline for creating the build project.
After successfully creating a building project, click next for the deploy stage.

Alt Text
Now Select s3 as deploy provider as we will host our app on AWS s3. You can choose which region you are using and for bucket option, we have to create a new bucket or select an existing bucket where we will host our application build files and check Extract file before deploy because after build process our build files have archived and we have to extract build archive to files for storing in s3. After these steps, click next for reviewing all of the configuration steps which you have made before.

After reviewing, click on the create pipeline button and you'll see your pipeline for source, build & deploy.

We just have done set up the automation process in AWS code pipeline service, now we have to create buildspec.yaml file in the root folder of our angular project. This is an important part of Continuous Integration, so we have to add our scripts carefully, otherwise, the build process will not succeed.

Here's what buildspec.yaml file looks like,

version: 0.1

      - echo installing nodejs...
      - curl -sL | bash -
      - apt-get install -y nodejs
      - echo installing yarn...
      - curl -sS | apt-key add -
      - echo "deb stable main" | tee /etc/apt/sources.list.d/yarn.list
      - apt install --no-install-recommends yarn
      - echo installing dependencies...
      - npm i -g @angular/cli
      - npm install
      # - echo testing...
      # - echo building...
      - ng build --prod
    - "**/*"
  discard-paths: no
  base-directory: dist/your-app-name

Enter fullscreen mode Exit fullscreen mode

Buildspec.yaml consist of phases of scripts, like in phases part first script is for installing nodejs with yarn. Let's look it one by one.

1) curl -sL | bash -

This command is responsible for downloading node.js version 12 tar file in the ubuntu container (environment for hosting our app)

2) apt-get install -y nodejs

If you're familiar with ubuntu, you'll know what apt-get does. It will install node.js in our container from that downloaded tar file.

3) curl -sS | apt-key add -

This command is for downloading the yarn package manager tar file. It's not mandatory to do it but I prefer it over npm commands.

4) apt install --no-install-recommends yarn

This command is for installing the yarn package manager.

Now in Pre-Build section,
We have to provide commands for installing dependencies of the project,

4) npm i -g @angular/cli

This command will responsible for install angular cli globally so that we can create builds by typing ng build. It's a mandatory step, otherwise it will not create a build.

5) npm install

This command will install all project-related dependencies which is required to run our app.

Now in build section,
We have to provide commands for creating a build of our project,

6) ng build --prod

It will create a production build of the angular project.

Now in artifacts section,
We have to provide files and base-directory name from where it will get build files after creating production build.

7) files "*/"

By this command, it will get all build files and upload it into AWS S3 services from where it will be hosted.

8) base-directory: dist/your-app-name

This will be the directory where your build files are.

Now after creating buildspec.yaml file in root, push your code to your repository's master branch, and it will automatically get your source code, create a build and deploy it to S3.

You can see from the above image, it will start building our project and you can see the logs from the details button.

Alright, when everything goes perfect, go to S3 service from AWS console and search your bucket. By going to your bucket you'll see your build files. Now go to the Properties tab and click static website hosting card. Check on Use this bucket to host a website option and write index.html in index and error document fields and save it. You'll see an endpoint of your application, open it new chrome tab and Boom, your site has been live on AWS S3.

Do try some changes in your code and push again to master, after creating build and deploy, it will show you the latest changes in your live app.

So that's it guys for automating your angular app to deployment.
BTW this process is same for react, vue or any framework, you just have to manipulate buildspec.yaml file scripts according to your scenario.

I hope you have learned something out of it. Please follow me here for more content like this.
