Drupal
A full FlowDrop backend shipped as a Drupal module — node definitions, workflow storage, execution, and triggers.
The Drupal server implementation is a complete FlowDrop backend packaged as a Drupal module. It serves node definitions, stores workflows as configuration entities, runs executions, and authenticates requests — everything the frontend–backend contract expects, integrated with the entities, users, and content you already have.

How it maps to FlowDrop
Everything you learned in Concepts carries over — the Drupal module is the backend that gives those workflows meaning:
| FlowDrop concept | In the Drupal server |
|---|---|
Node definitions (GET /nodes) | 25+ built-in node processors (data, control flow, entity operations, HTTP, AI), defined as PHP plugins |
| Workflow storage | Workflows are Drupal configuration entities — exportable to YAML, versionable in git, deployable with drush cex/cim |
| Execution | Runs every workflow the editor produces, recording results per node |
| Authentication | Standard Drupal permissions and session/token auth behind an AuthProvider |
What it adds on top
Beyond the core contract, the Drupal server brings backend-side capabilities the editor surfaces but does not itself implement:
- Execution modes — Synchronous (in-request), Asynchronous (queue-based background), and StateGraph (checkpointed, resumable).
- Triggers — start workflows automatically on entity changes, user events, or cron.
- Human-in-the-loop — pause execution for confirmations, choices, or free-text input.
- Pipelines and jobs — every run produces a pipeline record with one job per node for monitoring and debugging.
- Node Types — pre-set node variants site builders configure without code.
- Port shapes — name a domain data type (
Order,User), give it a JSON Schema, and every port carrying it gets a color, a badge, compatibility gating, and field-level template autocomplete. Declared in code by a module or in the UI by a site builder, and served to the editor as a data type schema.
