spiff-arena

SpiffArena is a low(ish)-code software development platform for building, running, and monitoring executable diagrams. It is intended to support Citizen Developers and to enhance their ability to contribute to the software development process. Using tools that look a lot like flow-charts and spreadsheets, it is possible to capture complex rules in a way that everyone in your organization can see, understand, and directly execute.

Please visit the SpiffWorkflow website for a Getting Started Guide to see how to use SpiffArena and try it out. There are also additional articles, videos, and tutorials about SpiffArena and its components, including SpiffWorkflow, Service Connectors, and BPMN.js extensions.

Backend Setup

First install python, poetry, and mysql. Then:

cd spiffworkflow-backend
poetry install
./bin/recreate_db clean
./bin/run_server_locally

If you want to run all locally:

If you're on a Mac and trying to run native (might translate elsewhere) running python 3 and get errors with mysqlclient and psycopgen2 when running the Poetry install, you may need to install mysql-client, pkg-config, mysqlclient, and psycopgen2 first, remove mysqlclient and psycopgen2 from the pyproject.toml (or Poetry will try to build them and crash), and run the Poetry install again.

brew install mysql-client pkg-config
export PKG_CONFIG_PATH="$(brew --prefix)/opt/mysql-client/lib/pkgconfig"
pip install mysqlclient
pip install psycopg2

Python3 also won't recognize MySQLdb as a module. After the above installs (which you would do pre-Poetry), add these lines to init.py in the backend project:

import pymysql; pymysql.install_as_MySQLdb()

On a Mac, port 7000 (used by the app) might be hijacked by Airplay. See the Docker section below.

Remember, if you don't need a full-on native dev experience, you can run the docker image, which saves you from all the native setup.

Keycloak Setup

You will want an openid server of some sort. There is one built in to the app that is used in the docker compose setup for simplicity, but non-compose defaults use a separate keycloak container by default. You can start it like this:

./keycloak/bin/start_keycloak

It'll be running on port 7002 (if you want to log into the keycloak admin, localhost:7002). Creds = admin/admin (also logs you into the app if running the front end)

Frontend Setup

First install nodejs, ideally the version in .tool-versions (but likely other versions will work). Then:

cd spiffworkflow-frontend
npm install
npm start

Assuming you're running KeyCloak as indicated above, login will be admin/admin.

Run tests

./bin/run_pyl

Run cypress automated browser tests

Get the app running so you can access the frontend at http://localhost:7001 in your browser by following the frontend and backend setup steps above, and then:

./bin/run_cypress_tests_locally

Docker

For full instructions, see Running SpiffWorkflow Locally with Docker.

The docker-compose.yml file is for running a full-fledged instance of spiff-arena while editor.docker-compose.yml provides BPMN graphical editor capability to libraries and projects that depend on SpiffWorkflow but have no built-in BPMN edit capabilities.

Note: For those who upgraded to MacOS 12.1 and are running everything locally, your AirPlay receiver may have started on Port 7000 and your docker (or anything requesting port 7000) may fail due to this port already being used. You can disable this port in System Preferences > Sharing > AirPlay receiver.

Contributing

To start understanding the system, you might:

  1. Explore the demo site via the Getting Started Guide
  2. Clone this repo, cd docs, run ./bin/build, and open your browser to http://127.0.0.1:8000 to view (and ideally edit!) the docs
  3. Check out our GitHub issues, find something you like, and ask for help on discord

Monorepo

This is a monorepo based on git subtrees that pulls together various spiffworkflow-related projects. FYI, some scripts:

ls bin | grep subtree
