Operational Monitoring: Zeebe Cloud Canary

Designing a resilient system means planning for, and alerting on various failure states. The Zeebe Cloud Canary npm package adds alerting to your Node.js Zeebe applications. There are a few things that can go wrong in a Zeebe system that you definitely want to surface operationally. Your client applications might exception and halt. The broker might fail – whether due to a hardware failure or some edge-case condition that puts it in an infinite restart loop while recovering (it could be memory constrained, for example, and rescheduled by K8s before it can recover its state on boot up). Both of these cases can be detected by probes. The broker has a readiness probe that can be monitored for this, and…

Coming in Zeebe 0.22: Awaitable workflow outcomes

The upcoming 0.22 release of Zeebe includes a feature many users have been asking for: the ability to start a workflow and retrieve its outcome with a single command. The new gRPC command CreateWorkflowInstanceWithResult is available for testing in the current SNAPSHOT Docker image of Zeebe and the zeebe-node-next version of the Node.js client. This command starts a workflow instance and returns the outcome when the workflow completes. Use-cases A common scenario is to start a workflow in response to a REST request, and send back the outcome from the workflow in the REST response. Previous implementations of this relied on a polling worker to retrieve the outcome, and the use of subscriptions to correlate it with the REST request…

Transactional Email Microservice with Zeebe and NestJS

NestJS is a JavaScript Microservices framework for Node.js inspired by Angular. For some time now, front-end developers have been able to get the benefits of configuration by convention, dependency injection, and composition using decorators to build code bases whose structure can scale. Now it’s time for backend developers to get the same benefits. NestJS is a framework that clearly meets a need felt in the community – it was the fastest growing Node.js framework in 2018 (measured by GitHub stars). NestJS leverages TypeScript, decorators, and the MVC architecture to enable developers to build applications that communicate over REST, WebSockets, gRPC, and GraphQL. With a new library from Dan Shapir – nestjs-zeebe – you can now integrate Zeebe into a NestJS…
