Skill Service

The Competence Repository Service allows content creators / teachers to develop their own competence repositories (i.e., taxonomies), share them with others, and use them to model required and offered competencies of a course.

Installation

npm install

Configuration

The service can be configured via the .env file placed in the root of this repository. These parameters may be overwritten by environment variables, as environment variable takes precedence over the parameters defined in the configuration file.

Database operations

# Start the dev-db docker container
npm run db:start

# Reset db without applying seed (e.g., after db is in inconsistent state but seed not needed)
npx prisma db push --force-reset

# Apply sample data (without clearing existing data)
npx prisma db seed

# Clear data and seed (e.g., after db is in inconsistent state and seed data is expected for local tests)
npm run db:redeploy

# Create and deploy a new db migration (after the db schema has been changed), will also seed the db (applying sample data)
npx prisma migrate dev

# Run the web-based client to browse and manipulate the dev-db
npx prisma studio

Running the app

# development
npm run start

# watch mode
npm run start:dev

# production mode
npm run start:prod

Test

# unit / integration tests (requires empty DB)
npm run test

# e2e tests
npm run test:e2e

# test coverage
npm run test:cov

Release Management

1. Merge all stable branches into main, which shall be included into the release.
2. Create a new data base migration, only if the prisma schema was changed since the last release: npx prisma migrate dev --name <a_concise_name_describing_the_db_change> Replace <a_concise_name_describing_the_db_change> with an appropriate name that describes the change.
3. Create a new tag in the Git repository, use semantic versioning according to our guide line. Also add a description to the tag that describes the change of the new release. Push the commit (depending on the tool, it may require some additional parameters to include tags).
4. Log into Jenkins and build the new release, it must not fail. Otherwise fix and prepare a new release
5. Log into GitHub and prepare a new release based on the given tag. Also add here the release description and add the link to the Docker container, which was built by Jenkins.
6. Ideally: Test the container + migration locally.
7. Increment the version number inside the package.json before adding any further changes to the main branch.
