Installing

npm i workit-bpm-client

How to use

    import { BasicAuthInterceptor, Client as CamundaExternalClient } from 'camunda-external-task-client-js';
    
    const basicOauth = { username: 'admin', password: 'admin123' };

    const config = {
      maxTasks: 32,
      workerId: 'demo',
      baseUrl: `http://localhost:8080/engine-rest`,
      topicName: 'topic_demo',
      bpmnKey: 'BPMN_DEMO',
      autoPoll: false,
      interceptors: [new BasicAuthInterceptor(basicOauth)]
    };

    const clientLib: ICamundaClient = new CamundaExternalClient(config);
    const client = new CamundaBpmClient(config, clientLib);
    
    await client.deployWorkflow('deploy-your.bpmn');
    await client.createWorkflowInstance({
        bpmnProcessId: "BPMN_DEMO",
        variables: {
            amount: 1000,
            hello: "world"
        }
    });
    await client.subscribe(async (message, service) => {
      // do something
    });
    
    // client contains other useful methods

Start a worker

    import { NodeTracer } from '@opentelemetry/node';
    import { BasicAuthInterceptor, Client as CamundaExternalClient } from 'camunda-external-task-client-js';
    import { FailureStrategySimple, SCProcessHandler, SuccessStrategySimple, Worker } from '@villedemontreal/workit-core';

    const clientLib: ICamundaClient = new CamundaExternalClient(config);
    const client = new CamundaBpmClient(config, clientLib);
    const successHandler = new SuccessStrategySimple();
    const failureHandler = new FailureStrategySimple();
    const tracer = new NodeTracer();
    const processHandler = new SCProcessHandler(successHandler, failureHandler, tracer);
    const worker = new Worker(client, processHandler);

    worker.start();
    worker.run();
