dmstr/flowable-bundle

Reusable Symfony bundle that exposes a Flowable BPMN engine as Doctrine-less API Platform pass-through resources, a per-request HTTP client and matching flowable:* CLI commands.

The bundle owns no database tables: every resource reads from and writes to a remote Flowable REST engine at request time. Connection details (base URL and credentials) are resolved per request from an ApiConfiguration of type flowable (provided by dmstr/api-configuration-bundle).

Requirements

• PHP >= 8.4
• Symfony 7
• API Platform 4
• A reachable Flowable REST engine (flowable-rest)

Installation

composer require dmstr/flowable-bundle

If you do not use a Symfony Flex recipe that registers the bundle, add it to config/bundles.php:

return [
    // ...
    Dmstr\Flowable\FlowableBundle::class => ['all' => true],
];

The bundle is self-wiring: it ships its own service definitions (FlowableBundle::loadExtension()), registers a dedicated flowable Monolog channel and needs no entry in the application's services.yaml. API Platform discovers the resource classes automatically from src/ApiResource.

Configuration

Create an ApiConfiguration of type flowable. Its configJson is validated against schema.json:

{
    "base_url": "http://flowable-rest:8080/flowable-rest/service",
    "auth_type": "basic",
    "username": "rest-admin",
    "password": "..."
}

auth_type is either basic (requires username + password) or bearer (requires token).

API resources

All resources are served under /api/flowable/*:

Resource	Notable operations
FlowDeployment	GET /deployments, GET /deployments/{id}, POST /deployments/upload, DELETE
FlowProcessDefinition	GET /process_definitions, POST /process_definitions/{id}/start
FlowProcessInstance	GET /process_instances, POST /process_instances, DELETE
FlowTask	GET /tasks, POST /tasks/{id}/complete, GET /tasks/{id}/input_schema
FlowExecution	GET /executions, POST /executions/{id}/trigger
FlowHistoric*	read-only history: activities, process instances, tasks, variables

The input_schema endpoint returns the per-task input JSON-Schema, resolved at runtime from either an authored <formKey>.schema.json deployment resource or by converting inline Flowable form-data — via the pluggable flowable.task_form_source chain.

CLI

Every REST operation has a matching command; command IDs mirror the resource URLs:

flowable:health
flowable:deployments                 flowable:deployments:upload
flowable:process-definitions
flowable:process-instances           flowable:process-instances:create
flowable:tasks                       flowable:tasks:complete
flowable:executions                  flowable:executions:trigger

Security

Reading is open to any authenticated user. Starting, triggering and completing (all write operations) require ROLE_FLOWABLE_ADMIN. The acting user is taken from the authenticated identity (JWT sub) and propagated to Flowable — see docs/tenant-and-user.md.
