In the previous article, when we talked about the task model, we mentioned blocking tasks, so how is this formed in the workflow? What is the relationship between blocking tasks and task models? Let’s do a simple analysis below. Here is still the simplest process as an example: Process definition Process Description node name display […]

About my realization of the vue functional pop-up window overflowing the project
vue functional pop-up window I have read a lot of articles before, and I always wanted to make my own, mainly based on secondary packaging and Vue.extend. I will share the pitfalls I stepped on and how to deal with them. The main functions are as follows: support title Load child component rendering Provides a […]
Workflow engine design and implementation · Parsing process definition files
In the previous article, we manually built a process object and simply printed and executed it. The way to build a process object is not very friendly. In order to build process objects more conveniently, we adopt a new method, that is, parse the process definition files mentioned in the basics and convert them into […]
Workflow engine design and implementation·Simple execution of process
Foreword The model has been highly abstracted above, and this article will further explain the model behavior. Here begins with a question: How to let the process go from the start node to the end node according to the arrow point? StartModel(start)->TaskModel(apply)->TaskModel(deptApprove)->EndModel(end) Execution process analysis Object graph: Timing diagram: Description of execution process: The start […]
Workflow engine design and implementation · Conditional process execution
In the simple execution of the process section, we let a common sequential process go from the start node to the end node. What if it is a conditional process? How should we deal with it? Process definition The flow chart rendered in the figure above can be generated from the following two process definition […]
