Prerequisites

1. Install the protobuf compiler using a package manager of your choice or using a binary from the github release page. The selected version has to match (or be older than) the version of protobuf-kotlin dependency used in build.gradle.kts.
2. Install Java JDK 17. If you use a later version, it has to be compatible with the configured Gradle version. Check the Gradle Compatibility Matrix for details.
3. Open the root project in IntelliJ.

Frontend

Frontend Setup

1. Install Android SDK via the Android plugin or Android Studio
2. Install fvm (flutter version manager)
3. Install flutter dependencies

cd frontend && fvm flutter pub get

4. Open IntelliJ settings and
   • Install the Android plugin and set the Android SDK path
   • Install the Dart plugin and set the Dart SDK path
   • Install the Flutter plugin and set the Flutter SDK path
5. Install app-toolbelt

npm install --unsafe-perm -g https://github.com/digitalfabrik/app-toolbelt/archive/refs/heads/main.tar.gz

Note: IntelliJ needs access to environment variables to run these commands successfully.

Run Frontend

1. Forward ports. As there are several services running and interacting some ports need to be forwarded. This includes the backend port 8000 and the map tiles port at 5002. The command has to be run every time a device is connected.

adb reverse tcp:8081 tcp:8081 && adb reverse tcp:8000 tcp:8000 && adb reverse tcp:5002 tcp:5002

2. Run the app
   • Bayern: Run (env:local+buildConfig:bayern)
   • Nuernberg: Run (env:local+buildConfig:nuernberg)
   • Koblenz: Run (env:local+buildConfig:koblenz)

Administration

Administration Setup

1. Create directory administration/src/generated

mkdir administration/src/generated

2. Install node_modules

npm install

Run Administration

Run Start administration (env:local+buildConfig:all) from Intellij run configurations

Backend

Backend Setup

1. Install docker and docker-compose
2. Setup docker-compose

docker-compose rm
docker-compose build
docker-compose up --force-recreate

3. Open the IntelliJ "Project Structure" and set up the required SDK called "entitlementcard-jdk" and point it to your JDK installation.
4. Run the backend migration (Migrate DB)

cd backend && ./gradlew run --args "migrate"

5. Create a backend account with one of the run configurations or the following command:

./gradlew run --args="create-admin <project> <role> <email> <password> <region>"`

Run Backend

1. Start docker-compose

sudo docker-compose up --force-recreate

2. Run the backend (Run backend (env:local+buildConfig:all))

./gradlew run --args="execute"

Optional Backend Setup

The following setup is only necessary if you work with the corresponding services.

Local Backend Configuration

The backend configuration file config.yml is checked in git and should therefore not be modified for development purposes. Instead, you can create your own local copy:

1. Copy config.yml to ~/.config/entitlementcard/config.yml

mkdir ~/.config/entitlementcard
cp backend/src/main/resources/config/config.yml ~/.config/entitlementcard

2. Adjust config

Map Styles

1. Clone the submodule inside backend/ehrenamtskarte-maplibre-style
2. Initialize all submodules by running git submodule update --init --recursive in the root directory

Matomo

0. Use the docker desktop client
1. Set up the matomo instance http://localhost:5003. The public version is available at https://matomo-entitlementcard.tuerantuer.org
2. Create an access token at localhost:5003/settings
3. Add localhost:5003 to matomos trusted_hosts at /var/www/html/config/config.ini.php
4. Add your matomo config for each project as described in Local Backend Configuration

projects:
  - id: ...
    # ...
    matomo:
      siteId: 1
      url: http://localhost:5003/matomo.php
      accessToken: <matomo-access-token>

Inspecting Services

• Adminer: http://localhost:5001 The credentials are:

  Property	Value
  Host (within Docker)	db-postgis
  Username	postgres
  Password	postgres
  Database	ehrenamtskarte

• Martin endpoints: http://localhost:5002/tiles/accepting_stores/index.json and http://localhost:5002/tiles/accepting_stores/rpc/index.json. The data shown on the map is fetched from a hardcoded url and is not using the data from the local martin!
• Map styles: http://localhost:5002/map.html

Dumping and Restoring the Database

docker exec -ti <container_id> pg_dump -c -U postgres ehrenamtskarte > dump-$(date +%F).sql

To copy the dump to your local machine:

rsync root@ehrenamtskarte.app:dump-2020-12-23.sql .

To restore the dump

docker exec -i <container_id> psql ehrenamtskarte postgres < dump-$(date +%F).sql

Using ehrenamtskarte.app as Database

ssh -L 5432:localhost:5432 -L 5001:localhost:5001 team@ehrenamtskarte.app

That way the Adminer and postgres will be available locally.
