🔧 Configuration

Worker Architecture

import { OrkesClients, TaskHandler, worker, simpleTask, ConductorWorkflow } from "@io-orkes/conductor-javascript";
import type { Task, TaskResult } from "@io-orkes/conductor-javascript";

// 1. Define workers with @worker decorator
@worker({ taskDefName: "my_task", concurrency: 5, pollInterval: 100 })
async function myTask(task: Task): Promise<TaskResult> {
  return { status: "COMPLETED", outputData: { result: "done" } };
}

// 2. Connect to Conductor
const clients = await OrkesClients.from();

// 3. Build and register workflows
const wf = new ConductorWorkflow(clients.getWorkflowClient(), "my_workflow")
  .add(simpleTask("my_ref", "my_task", { key: "${workflow.input.key}" }));
await wf.register();

// 4. Start workers + execute
const handler = new TaskHandler({ client: clients.getClient(), scanForDecorated: true });
await handler.startWorkers();
const run = await wf.execute({ key: "value" });
await handler.stopWorkers();

Environment Variables

Variable	Description	Default
`CONDUCTOR_SERVER_URL`	Conductor server URL	Required
`CONDUCTOR_AUTH_KEY`	Authentication key ID	—
`CONDUCTOR_AUTH_SECRET`	Authentication secret	—
`LLM_PROVIDER`	LLM integration name	`openai_integration`
`LLM_MODEL`	LLM model name	`gpt-4o`
`EMBEDDING_PROVIDER`	Embedding model integration	`openai_integration`
`EMBEDDING_MODEL`	Embedding model name	`text-embedding-3-small`
`VECTOR_DB`	Vector DB integration name	`pinecone_integration`
`VECTOR_INDEX`	Vector DB index name	varies
`MCP_SERVER`	MCP server integration name	`weather_mcp_server`

🐛 Common Issues

Workers don't pick up tasks

Ensure CONDUCTOR_SERVER_URL is set correctly
Workers must be started (handler.startWorkers()) before executing workflows
Check the taskDefName matches between @worker and simpleTask

Decorator errors (TS1206)

Add "experimentalDecorators": true to your tsconfig.json
Or use npx ts-node --compiler-options '{"experimentalDecorators":true}'

Express example requires express

Install: npm install express @types/express

AI/LLM examples fail

Requires an LLM integration configured in Conductor (e.g., OpenAI)
Set LLM_PROVIDER and LLM_MODEL environment variables
Verify the integration is active in the Conductor UI

Vector DB examples fail

Requires a vector DB integration (e.g., Pinecone, Weaviate)
Set VECTOR_DB and VECTOR_INDEX environment variables
