Environment Variables

The following environment variables are recognized by the frontend process.

Name Possible Values Description
HD_BASE_URL Any URL with protocol, domain and optionally directory and port. Must end with a trailing slash. (e.g. http://localhost:3001/) The URL under which the frontend is expected. Setting this is mandatory so the server side rendering can generate assets URLs. You only need to set this yourself if you use the production mode.
HD_RENDERER_BASE_URL Same as HD_BASE_URL You can provide this variable if the renderer should use another domain than the editor. This is recommended for security reasons but not mandatory. This variable is optional and will fallback to HD_BASE_URL
NEXT_PUBLIC_USE_MOCK_API true, false Will activate the mocked backend
NEXT_PUBLIC_TEST_MODE true, false Will activate additional HTML attributes that are used to identify elements for test suits.

Variables that start with NEXT_PUBLIC_ will be compiled into the build. You can't change them at after compilation. You shouldn't need to set them yourself. Use the designated npm tasks instead.

UI Test

Curious about the new look and feel? We provide a demo of the new UI on hedgedoc.dev. This version uses mocked data and has no data persistence.

The UI test is hosted by netlify. Please check their privacy policy as well as ours.

Running Tests

Unit

Unit testing is done via jest.

  1. Run yarn test

End2End

We use cypress for e2e tests.

  1. Start the frontend with yarn start:dev:test (or use a test build using yarn build:test which you can start using yarn start). The usage of :test is mandatory!
  2. Run yarn cy:open to open the cypress test loader
  3. Choose your browser and start a test suite

To run all tests in a headless browser use yarn cy:run:chrome or yarn cy:run:firefox

Bundle analysis

You can inspect the generated production-bundle files to look for optimization issues.

  1. run yarn analyze. This will overwrite any existing builds!
  2. Open the generated .next/server/analyze/server.html in your favourite browser
