Camunda Node.js External Task Client 0.1.0-alpha Released

We are so excited to announce what the team has been cooking for the past few weeks: camunda-external-task-client.js, a Node.js client for Camunda External Tasks! The main features set includes: Fetch & Lock Tasks Globally Task Completion Lock Time Manipulation Fetch & Lock Tasks Globally A detail about the Camunda Engine API worth pointing out is that it’s possible to fetch external tasks as a batch independently of their specific topics.

Custom Queries

Why Custom Queries? The process engine offers a pretty straightforward and easy to use Java Query API. If you want to build a task list you just write something like this: @Inject private TaskService taskService; public List<Task> getAllTasks() { return taskService.createTaskQuery().taskAssignee("bernd").list(); } Easy as it is, there are basically two catches: You can only build queries that the API supports. You cannot add constraints on your domain objects. Let us give you a simple use case example, which we implemented in the custom-queries example: You have a process variable “customer” holding the customerId You have your own entity “Customer” with all the details So far, a pretty common situation (please note that the object diagram has been simplified to show…
