Development

Local setup

Clone this repository, install deps and create an .env.local file by running:

yarn
cp .env.example .env.local

Adjust values in the created .env.local accordingly.

Start dev server

Start the frontend with a dev server by running:

yarn start

Build production bundle

yarn build

Run unit tests

yarn test

Run integration tests

We use cypress for handling integration tests. To run the tests locally, first make sure to have a local dev sever running:

yarn start

If you want to start the cypress UI run:

yarn cypress:open

If you want to run the tests from the CLI, run:

yarn cypress:run

Per default cypress expects the frontend running on http://localhost:3000. To change that run:

CYPRESS_BASE_URL=http://localhost:3333 yarn cypress:run

Important CSS values

Z-index

Navbar - 1000 Toast - 99999 Modal - 99998
