How to Contribute to this Project

Development server

DSP-APP is built with Angular and uses NPM.

You have to install the corresponding packages with npm i. Now you have to possibilites to run the application in developer mode:

  • With a local installed DSP-API environment run ng serve or npm run start.
  • If you want to connect to the DSP-API on our test server run ng serve --configuration=test-server or npm run start-with-test-server. Please consider which version of DSP-API is currently running on the test server (see webapi: With this solution you will also have access to all the representation files.

In both case navigate to The app will automatically reload if you change any of the resource files.

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.


Run npm run build to build the app. The build artifacts will be stored in the dist/ directory. Run the command npm run build-prod for a production build.


The following tests (unit, e2e and lint) are part of the Github Actions (CI) workflow and has to be run successfully before the code can be merged into the main branch.

Running unit tests

Run npm run test-local to execute the unit tests via Karma on your local computer.

Run npm run test-ci to execute the unit tests via Karma without a browser. It is used in the Github Actions (CI) workflow.

Running end-to-end tests

Run npm run test-e2e-protractor to execute the end-to-end tests via Protractor.

Running code linter

Run npm run lint-local to execute the lint service via ESLint. This command uses the --fix flag which fixes simple errors like redundant type if you have default value assigned. In the Github Actions (CI) workflow the linter runs as npm run lint-ci.

To integrate ESLint with Visual Studio Code, do the following:

  • Install the ESLint extension.
  • Create a task via the Tasks: Configure Task command and select npm: lint-local.
  • In the resulting tasks.json file, configure the problem matcher to be $eslint-stylish.
