helpwave tasks

helpwave tasks is a modern, open-source task and ward-management platform tailored for healthcare - designed to bring clarity, efficiency and structure to hospitals, wards and clinical workflows.

⚠️Pre-release — not for productive use. This project is still under active development and has not been released yet. It is not ready for production or real patient data, and no stability, security, or data-safety guarantees are made at this stage. We expect this to change over the coming month. Until then, use it for evaluation and development only.

Quick Start

If you simply want to test the application without modifying code, use the production compose file. This pulls official images and runs them behind a reverse proxy.

1. Run the Stack

   docker-compose up -d

2. Access the App

   • App URL:http://localhost:80
   • User:test / test

Development

This section covers setting up the local environment for coding. You need PostgreSQL, Redis, Keycloak, and InfluxDB running to support the backend.

Environment Configuration

The application relies on the following services. Ensure your environment variables are set:

DATABASE_URL="postgresql+asyncpg://postgres:password@localhost:5432/postgres"
REDIS_URL="redis://:password@localhost:6379"
ENV=development
INFLUXDB_URL="http://localhost:8086"
INFLUXDB_TOKEN="tasks-token-secret"
INFLUXDB_ORG="tasks"
INFLUXDB_BUCKET="audit"

Option A: Manual Setup (Docker Compose)

Use this if you prefer managing your own Python and Node versions.

1. Start Infrastructure Start Postgres, Redis, Keycloak, and InfluxDB:

   docker-compose -f docker-compose.dev.yml up -d postgres redis keycloak influxdb

2. Run Backend

   cd backend
   python -m venv venv
   source venv/bin/activate
   pip install -r requirements.txt
   alembic upgrade head
   uvicorn main:app --reload

3. Run Frontend In a new terminal:

   cd web
   npm install
   npm run dev

4. Run Simulator (Optional) In a new terminal:

   cd simulator
   python -m venv venv
   source venv/bin/activate
   pip install -r requirements.txt
   python -m simulator

Option B: Nix flake

Requires Nix with flakes enabled. The flake provides pure packages, a side-effect-free nix develop shell, and a NixOS module. Infrastructure (Postgres, Redis, Keycloak, InfluxDB) still comes from Docker Compose in the develop shell.

Develop

nix develop
# or from anywhere:
nix develop github:helpwave/tasks

First time only for the frontend checkout:

(cd web && npm ci)

Then:

run-dev-all
# optional:
run-simulator

Helpers on PATH: run-dev-backend, run-dev-web, run-dev-all, run-alembic, run-alembic-upgrade, psql-dev, redis-cli-dev, start-docker, stop-docker, clean-dev, run-simulator, lint-dockerfiles, run-act.

The develop shell does not create venv/ or run npm install into the tree.

Run / install from GitHub

nix run github:helpwave/tasks # usage help
nix run github:helpwave/tasks#backend
nix run github:helpwave/tasks#web
nix run github:helpwave/tasks#simulator
nix run github:helpwave/tasks#proxy
nix profile install github:helpwave/tasks#backend
nix profile install github:helpwave/tasks#web

Standalone packages expect configured Postgres, Redis, Keycloak, and InfluxDB (or use the NixOS module below).

NixOS module

{inputs.helpwave-tasks.url="github:helpwave/tasks";outputs={nixpkgs,helpwave-tasks, ... }: {nixosConfigurations.example=nixpkgs.lib.nixosSystem{system="x86_64-linux";modules=[helpwave-tasks.nixosModules.default{services.helpwave-tasks.enable=true;# services.helpwave-tasks.backend.environmentFile = "/run/secrets/tasks.env";# services.helpwave-tasks.keycloak.issuerUri = "https://auth.example/realms/tasks";}];};};}

Local Postgres and Redis are enabled by default. Optional InfluxDB 2 and Keycloak can be turned on with influxdb.createLocally / keycloak.createLocally. Put secrets in backend.environmentFile.

Access & Credentials

Once the development environment is running:

Service	URL	Description
Web Frontend	http://localhost:3000	The user interface (Next.js/React).
Backend API	http://localhost:8000/graphql	The GraphQL Playground (Strawberry).
Keycloak	http://localhost:8080	Identity Provider.
InfluxDB	http://localhost:8086	Time-series database for audit logs.

Keycloak Realms & Users:

• tasks Realm:http://localhost:8080/realms/tasks (Redirects automatically from app login)
  • User: test
  • Password: test
• master Realm (Admin Console):http://localhost:8080/admin
  • User: admin
  • Password: admin

Project Structure

• backend/ - FastAPI backend with GraphQL API (Strawberry)

Testing

Running Tests Locally

Backend Tests:

cd backend
python -m pytest tests/unit -v
python -m pytest tests/integration -v

Frontend Linting:

cd web
npm run lint

E2E Tests:

cd tests
npm install
npx playwright test

Running GitHub Actions Locally

You can run GitHub Actions workflows locally using act. See .github/workflows/README.md for detailed instructions.

Quick start:

# Install act (requires Docker)
brew install act # macOS# or download from https://github.com/nektos/act/releases# Run all workflows
act
# Run specific job
act -j backend-tests

Docker Images

Images are built from Nix (scratch rootfs). GHCR tags on main:

• ghcr.io/helpwave/tasks-backend:latest
• ghcr.io/helpwave/tasks-web:latest
• ghcr.io/helpwave/tasks-simulator:latest
• ghcr.io/helpwave/tasks-proxy:latest

Build locally via stream:

nix build .#backend-docker && ./result | docker load
nix build .#web-docker && ./result | docker load

Or via two-step Dockerfiles (nixos/nix → scratch), from the repo root:

docker build -f backend/Dockerfile -t helpwave-tasks-backend .
docker build -f web/Dockerfile -t helpwave-tasks-web .
docker build -f proxy/Dockerfile -t helpwave-tasks-proxy .
docker build -f simulator/Dockerfile -t helpwave-tasks-simulator .
