A visualisation utility for Europeana API data.
Make sure you have node version 14.7.8 and npm version 6.x:
node --version
npm --version
Get the npm dependencies:
npm install
To facilitate containerisation the standard angular way of setting environment variables has been amended.
The standard environment.ts file exists under src/app/environments/ but its contents define a function that can load variables from an external source, in this case src/assets/env.js.
The file src/assets/env.js should therefore be modified before starting the development server.
Run npm run start for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
The main branch for development is the develop branch. But do NOT use this branch directly! Use a new branch for features/bugs and give it a descriptive name containing the user story code, like:
feat/MET-1535-chart-styling
bug/MET-3245-dashboard-not-loading
If you push a branch or commit to GitHub, it will automatically be tested by Travis CI. This will take about 5 mins and the results will be shown in GitHub, e.g. in the pull request page.
Make a pull request in GitHub for code review and merging.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
To run the unit tests in development (watch mode):
npm run test:dev
To run the cypress tests:
npm run test:e2e
To run the cypress tests in development (watch mode), start the dev server in one terminal window:
npm run start:ci
...start the dev data server in another terminal window:
npm run start:ci-data
...and then run cypress in another window:
npm run cypress
To run the accessibility tests:
npm run test:accessibility
We use jenkins to deploy. Make sure you can access https://jenkins.eanadev.org/ and use the following jobs:
statistics-dashboard-teststatistics-dashboard-acceptance
To make a (parameterised) docker image of the app first run this command:
npm run dist-localised
and then copy the output of that command (from the dist directory) into a docker nginx image:
docker build -t statistics-dashboard-app-image:version .
The image runtime configuration is only set on container startup, so environment variables have to be passed when it's run. Here they are passed using the (local) project env_file:
docker run -it --rm -d -p 8080:8080 --env-file=deployment/local/env_file --name stats-dash statistics-dashboard-app-image:version
As with the src/assets/env.js file for the development server, the env_file file should be adjusted before the nginx server is started.
Note: by default the docker image's nginx is configured to redirect the browser to the https protocol. To run the image locally or in environments that haven't been configured for https the image can be run with the nginx.conf file mapped to a non-https variant by using the -v (volume) option, i.e.:
docker run -it --rm -d -p 8080:8080 --env-file=deployment/local/env_file -v deployment/local/nginx.conf:/etc/nginx/nginx.conf --name stats-dash statistics-dashboard-app-image:version
Running the script:
./deployment/k8s-deploy.sh -i myDockerImage
will deploy the app to a local Kubernetes cluster.
The script accepts the parameter flags:
- -c (context) the kubernetes context
- -d (delete) flag that the app should be deleted
- -h (help) shows a help message
- -i (image) the application image to deploy
- -r (replicas) hyphen-separated integers defining the min / max number of replicas
- -t (target) the deploy target: local, test, acceptance, production
- -u (utilisation) the CPU usage threshold for autoscaling
so the command:
`./deployment/k8s-deploy.sh -d -t acceptance -i myDockerImage`
...will delete myDockerImage in the default context with the acceptance namespace.
