To run interactive Cypress tests npm run e2e:open

NOTE: before running the e2e tests the following env vars need to be set:

CYPRESS_AAD_TENANT_ID=
CYPRESS_AAD_CLIENT_ID=
CYPRESS_AAD_APP_CLIENT_SECRET=
CYPRESS_TEST_USER_EMAIL=
CYPRESS_TEST_USER_PASSWORD=

To generate GraphQL hooks npm run codegen

Development Setup with other @lcacollect packages

You can use npm link to set up live reloading of the other @lcacollect packages.

• Clone the package that you wish to enable live reload on.
• In the terminal, go the root folder of the cloned repo and write npm link in the terminal
• Go back to this repo's root folder and write npm link @lcacollect/{PACKAGE} to link the package.

Example of a oneliner for linking the project package (executed from lcacollect/frontend/):

npm link ../shared-project-frontend && npm link @lcacollect/project

• When you make changes to the package, that you wish to see in this app, simply run npm run build in the package and the changes will available here.
• To enable hot reloading for a linked project, go to vite.config.ts and remove the comment // for the linked project you want to enable hot reloading for (NB! Only 1 project at a time). Then open a new terminal in the directory of the linked project and run npm run build:watch, to see changes live locally.

Example where the project package is enabled for hot reloading:

optimizeDeps: {
    exclude: [
      // '@lcacollect/assembly',
      // '@lcacollect/documentation',
      '@lcacollect/project',
      // '@lcacollect/core',
      // '@lcacollect/components',
      // '@lcacollect/e2e-testing',
    ],
    ...
}
