Angular JumpStart with TypeScript

The goal of this jumpstart app is to provide a simple way to get started with Angular 2+ while also showing several key Angular features. The sample relies on the Angular CLI to build the application.

Looking for expert onsite Angular/TypeScript training? We've trained the biggest (and smallest :-)) companies around the world for over 15 years. For more information visit https://codewithdan.com.

Angular Concepts Covered

  • TypeScript version that relies on classes and modules
  • Modules are loaded with System.js
  • Defining routes including child routes and lazy loaded routes
  • Using Custom Components including custom input and output properties
  • Using Custom Directives
  • Using Custom Pipes
  • Defining Properties and Using Events in Components/Directives
  • Using the Http object for Ajax calls along with RxJS observables
  • Working with Utility and Service classes (such as for sorting and Ajax calls)
  • Using Angular databinding Syntax [], () and [()]
  • Using template-driven and reactive forms functionality for capturing and validating data
  • Optional: Webpack functionality is available for module loading and more (see below for details)
  • Optional: Ahead-of-Time (AOT) functionality is available for a production build of the project (see below for details)

Running the Application with Node.js

  1. Install the latest LTS version of Node.js from https://nodejs.org. IMPORTANT: The server uses ES2015 features AND the Angular CLI so you need a current version of Node.js.

  2. Run npm install to install app dependencies

  3. Run ng build angular-jumpstart --watch to build and bundle the code

  4. Run npm start in a separate terminal window to launch the web and RESTful API server

  5. Go to http://localhost:8080 in your browser

NOTE: You'll need to supply your own Google Maps API key in the shared/map.component.ts file to see the full map functionality. Update https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY with your key.

Simply clone the project or download and extract the .zip to get started.

Once the app is running you can play around with editing customers after you login. Use any email address and any password that's at least 6 characters long (with 1 digit).

Here are a few screenshots from the app:







Running Cypress End to End Tests

  1. Run npm install cypress --save-dev to install Cypress.
  2. Run npm run cypress to start the Cypress test runner.

Running in Kubernetes

  1. Install Docker Desktop from https://www.docker.com/get-started
  2. Start Docker and enable Kubernetes in the Docker Desktop preferences/settings
  3. Run docker-compose build to create the images
  4. Run kubectl apply -f .k8s to start Kubernetes
  5. Visit http://localhost
  6. Stop Kubernetes using kubectl delete -f .k8s

Running with Skaffold

If you'd like to use the Skaffold tool to run the project in Kubernetes, install it, and run the following command:

skaffold dev

To generate the skaffold.yaml file that's included in the project the following command was run and the image context paths it defines were modified:

skaffold init -k '.k8s/*.yml' \
  -a '{"builder":"Docker","payload":{"path":".docker/nginx.dev.dockerfile"},"image":"nginx-angular-jumpstart"}' \
  -a '{"builder":"Docker","payload":{"path":".docker/node.dockerfile"},"image":"node-service-jumpstart"}'

If you wanted to generate the initial Kubernetes manifest files from an existing docker-compose.yml file you can use the following command. It uses the Kompose tool behind the scenes to create the YAML files

skaffold init --compose-file docker-compose.yml \
  -a '{"builder":"Docker","payload":{"path":".docker/nginx.dev.dockerfile"},"image":"nginx-angular-jumpstart"}' \
  -a '{"builder":"Docker","payload":{"path":".docker/node.dockerfile"},"image":"node-service-jumpstart"}'

Azure Container Apps

Build API Image

  1. Go to https://github.com/danwahlin/angular-jumpstart and fork the repo.

  2. Clone the forked repo to your machine.

  3. Run docker-compose build node.

  4. Tag the image with your Docker Hub repo name: docker tag node-service-jumpstart <YOUR_DOCKER_HUB_NAME>/node-service-jumpstart

  5. docker push <YOUR_DOCKER_HUB_NAME>/node-service-jumpstart

Create environment

az containerapp env create -n angular-jumpstart-env -g Angular-Jumpstart-RG \
--location westus3

Deploy the API Container App

az containerapp create -n angular-jumpstart-api -g Angular-Jumpstart-RG \
--environment angular-jumpstart-env \
--image <YOUR_DOCKER_HUB_NAME>/node-service-jumpstart \
--ingress external --target-port 8080

Note the fully qualified domain (fqdn) value assigned to the angular-jumpstart-api container app. You'll need this value in the next section.

Add an .env File

  1. Create a .env file in the project root.

  2. Add the following key/value to the .env file:

NG_APP_API_URL=<FQDN_VALUE_FROM_YOUR_angular-jumpstart-api_CONTAINER_APP>

Build the UI Image

  1. Run docker-compose build nginx.

  2. Tag the image with your Docker Hub repo name:

    docker tag nginx-angular-jumpstart <YOUR_DOCKER_HUB_NAME>/nginx-angular-jumpstart

  3. Push the image to Docker Hub:

    docker push <YOUR_DOCKER_HUB_NAME>/nginx-angular-jumpstart

Deploy UI Container App

Change the image name below to match your image tag from the previous step.

az containerapp create -n angular-jumpstart-ui -g Angular-Jumpstart-RG \
--environment angular-jumpstart-env \
--image <YOUR_DOCKER_HUB_NAME>/nginx-angular-jumpstart \
--ingress external --target-port 80

View the UI App

Navigate to the FQDN value shown after running the previous command.

Add GitHub Continuous Deployment

  1. Create a service principal:

    az ad sp create-for-rbac \
  --name AngularJumpStartServicePrincipal \
  --role "contributor" \
  --scopes /subscriptions/<SUBSCRIPTION_ID>/resourceGroups/Angular-Jumpstart-RG \
  --sdk-auth

  2. Add a GitHub action for the UI container app:

    az containerapp github-action add \
  --repo-url "https://github.com/<OWNER>/<REPOSITORY_NAME>" \
  --context-path "./.docker/nginx.dockerfile" \
  --branch main \
  --name angular-jumpstart-ui \
  --image <YOUR_DOCKER_HUB_NAME>/nginx-angular-jumpstart
  --resource-group Angular-Jumpstart-RG \
  --registry-url docker.io \
  --registry-username <REGISTRY_USER_NAME> \
  --registry-password <REGISTRY_PASSWORD> \
  --service-principal-client-id <CLIENT_ID> \
  --service-principal-client-secret <CLIENT_SECRET> \
  --service-principal-tenant-id <TENANT_ID> \
  --login-with-github

  3. Add a GitHub action for the API container app:

    az containerapp github-action add \
  --repo-url "https://github.com/<OWNER>/<REPOSITORY_NAME>" \
  --context-path "./.docker/node.dockerfile" \
  --branch main \
  --name angular-jumpstart-api \
  --image <YOUR_DOCKER_HUB_NAME>/node-service-jumpstart
  --resource-group Angular-Jumpstart-RG \
  --registry-url docker.io \
  --registry-username <REGISTRY_USER_NAME> \
  --registry-password <REGISTRY_PASSWORD> \
  --service-principal-client-id <CLIENT_ID> \
  --service-principal-client-secret <CLIENT_SECRET> \
  --service-principal-tenant-id <TENANT_ID> \
  --login-with-github

  4. IMPORTANT: Once the GitHub actions are added, pull the latest changes to your local repository.

  5. Open each action file in .github/workflows and change the properties under on: to the following (in both files):

    # When this action will be executed
on:
  push:
    branches:
    - main
  pull_request:
    types: [opened, synchronize, reopened, closed]
    branches:
    - main

  6. Make the following changes to each respective workflow file:

    angular-jumpstart-ui workflow

    build-args: NG_APP_API_URL=${{ secrets.NG_APP_API_URL }}
file: ./.docker/nginx.dockerfile
context: ./

    angular-jumpstart-api workflow

    file: ./.docker/node.dockerfile
context: ./

  7. Go to your GitHub.com and navigate to your forked repo. Select Settings --> Secrets --> Actions from the toolbar.

  8. Add the following key/value into the repository secrets. This is needed for the CI build that generates the UI image.

    NG_APP_API_URL=<FQDN_VALUE_FROM_YOUR_angular-jumpstart-api_CONTAINER_APP>

  9. Push your changes up to your repo.

  10. Go to your GitHub repo on Github.com and select Actions from the toolbar. You should see the actions building (and hopefully deploy successfully).

  11. Go to the FQDN of your angular-jumpstart-ui container app in the browser. The app should load if your GitHub actions deployed successfully.
