Development

Requirements

• Node.js >= 20.0.0
• Docker (Redis dependency)
• npm 7 or greater
• strapi (see below)

Strapi

Three options:

1. A local strapi instance:

   • Start strapi locally,
   • configure .env with CMS=STRAPI and STRAPI_API pointing to your local strapi instance (cp .env.example .env should do the trick)

2. Using the the deployed staging strapi instance:

   • Set STRAPI_API=<STRAPI_STAGING_URL>/api and set STRAPI_ACCESS_KEY to your token (create a new key in the strapi GUI at "Settings" > "API Tokens" > "Create new API Token")

3. Use a local content file:

   • Set STRAPI_API and STRAPI_ACCESS_KEY to point to staging like in option 2.
   • Set CMS=FILE
   • Run npm run build:localContent (should have generated a content.json file)

Locales

For each Strapi page, there are two locales: Staging (sg) and Production (de). This is because while we're able to feature flag code changes in PostHog, we aren't able to feature flag content changes in the CMS. E.g. If we want to test out content changes, like different components on the same page, we must use Strapi's Locale feature, as Multi-Environments is only supported by Strapi Cloud.

The App first checks to see if valid staging data exists, and if not, pull the requested data from the production environment. By default, we develop features in the Production environment.

Run Server in Development Mode

npm install
docker compose up -d
npm run dev

This starts your app in development mode, rebuilding assets on file changes. Open the app in localhost:3000

Tests

Unit tests

• run: npm run test
• run in watch mode: npm run test:watch
• run with coverage: npm run test:coverage
• run subset: npm run test -- -t "STRING_TO_MATCH"

E2E tests

• run: npm run test:e2e
• UI: npm run test:e2e:ui
• debug (F10 to step over): npx playwright test --debug

Note

Remember to install playwright cli and set the environment variable GERICHTSFINDER_ENCRYPTION_KEY.

Write E2E tests

• getting started writing tests
• use codegen as an aid: npx playwright codegen localhost:3000/kitchensink

Debug E2E tests in CI

1. download playwright-report.zip artifact from GitHub action summary page (only present on e2e failure for 30 days)
2. unzip
3. npx playwright show-trace <DOWNLOAD_PATH>/data/<HASH>.zip

Git Hooks

We use lefthook for running several pre-commit hooks,install them using npm run init.

The git hooks check formatting, linting, unit tests, typecheck (see lefthook.yaml for more details). You may execute them before commiting using lefthook run pre-commit.

How to add a new "Antrag" or form pdf to services/pdf/

1. Create a new folder for example: prozesskostenhilfe
2. Store the antrag or form pdf there: prozesskostenhilfe/Erklaerung_Verhaeltnisse_Prozess_oder_Verfahrenskostenhilfe.pdf
3. Run npm run build:pdf

After running the command, a new file named prozesskostenhilfe.generated.ts will be generated in the specified directory. You can use this file to fill out the PDF based on the input fields defined within it.

How to add a new Array page to a form flow (UNDER CONSTRUCTION)

(This section is still under construction, as there are still open questions about what the generic array case is [or should be] and how to document it) Form flow arrays should, generally speaking, be defined like the following inside of flow.json:

"<Plural name>": {
   "initial": "<Plural name>-frage",
   "states": {
      "<Plural name>-frage": {
         "on":
            {
            "SUBMIT": [
               {
                  "guard": "hasOther<Plural name>",
                  "target": "uebersicht"
               }
            ],
            "BACK": "<Previous step>"
         }
      },
      "uebersicht": {
         "on": {
            "SUBMIT": [
               {
                  "guard": "hasOther<Plural name>AndEmptyArray",
                  "target": "warnung"
               }
            ],
            "BACK": "<Plural name>-frage",
            "add-<Plural name>": {
               "guard": "isValid<Plural name>ArrayIndex",
               "target": "<Singular name>"
            }
         }
      },
      "warnung": {
         "on": {
            "BACK": "uebersicht",
            "SUBMIT": "<Next Step>"
         }
      },
      "<Singular name>": {
         "initial": "daten",
         "states": {
            "daten": {
               "on": {
                  "BACK": "#<Plural name>.uebersicht",
                  "SUBMIT": "#<Plural name>.uebersicht"
               }
            }
         }
      }
   }
}

Note the following:

• The step begins with a ____-frage step, usually a yes/no radio page, indicating whether or not to show the ArraySummary page at all. E.g. "Do you have any additional income you would like to report?"
• The uebersicht page is the ArraySummary, which will display all the items the user has added, along with an "Add item" button
• warnung is necessary as a type of form validation, to ensure that the user has entered >= 1 item (actual form validation would be tricky here, so displaying a warning to the user is the next best thing)
• Finally, the <Singular name> step is basically a placeholder for the data entered per item (daten), so that the url reads as <Singular name>/<item number>/daten e.g. arbeitsausgabe/0/daten

After these steps have been entered in flow.json, we need to define the matching ArrayConfigServer in index.ts of the respective flow:

config: _.merge(<flow>, {
   meta: {
      arrays: {
         <Plural name>: {
            url: "/<flowId>/<stepId>/<Plural name>/<Singular name>",
            initialInputUrl: "daten",
            event: "add-<Plural name>",
         },
      } satisfies Partial<Record<AllContextKeys, ArrayConfigServer>>,
   }
})

(If multiple ArrayConfigServers are being added, it might be sensible to add them to an arrayConfigurations.ts file and spread them in)

Storybook

We have a storybook instance running. On the Staging and preview environments it can be accessed via /storybook. In development mode, run the npm run start:storybook command.
