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.
