Tutorials
Step-by-step tutorials for building FlowDSL flows and nodes.
These tutorials take you from zero to production-ready FlowDSL flows. Each one is self-contained and builds a real use case — not toy examples. By the end you will know how to design flow documents, choose delivery modes, implement custom nodes in Go or Python, and operate FlowDSL locally with Docker Compose.

Prerequisites
Most tutorials assume:
- Basic familiarity with YAML
- Docker Desktop installed (for local infrastructure tutorials)
- A terminal and a code editor
Node implementation tutorials additionally require:
- Go tutorials: Go 1.21 or later
- Python tutorials: Python 3.10 or later,
pip
You do not need expertise in Kafka, MongoDB, or Redis. FlowDSL abstracts those behind delivery mode declarations — the runtime handles transport configuration.
New to FlowDSL? Start with Getting Started — it takes five minutes and gives you a complete mental model before you build anything from scratch.
