Temporal Graph Workflow Worker

Temporal worker application for executing graph-defined document workflows.

What Runs Here

  • Workflow type: graphWorkflow (src/graph-workflow.ts)
  • DAG execution engine: src/graph-engine/*
  • Activities: src/activities/* (registered through src/activity-registry.ts)

Backend starts executions through:

  • apps/backend-services/src/temporal/temporal-client.service.ts

Setup

npm install
npm run db:generate
npm run build

Start worker:

npm run dev

or

npm start

Common Scripts

  • npm run build
  • npm run dev
  • npm run start
  • npm run test
  • npm run type-check

Testing Scope

  • Graph workflow integration: src/graph-workflow.test.ts
  • Graph engine unit tests: src/graph-engine/*.test.ts
  • Validator/expression tests
  • Activity tests: src/activities/*.test.ts

Static Assets

osd.traineddata

This file is Tesseract's Orientation and Script Detection trained model, required by the document.normalizeOrientation activity. It must be present in apps/temporal/ at runtime.

Without it, createWorker("osd", OEM.TESSERACT_ONLY) will fail when the activity attempts to detect page rotation. Tesseract.js can download language data at runtime, but committing this file avoids network dependency in containers and local dev.

Do not delete this file.
