Elsa intrinsically supports triggering events that starts new workflows and resumes halted workflow instances in an easy to use manner. E.g. workflowHost.TriggerWorkflowAsync("HttpRequestTrigger");"will start and resume all workflows that either start with or are halted on the HttpRequestTrigger.Elsa has a web-based workflow designer. I once worked on a project for a customer that was building a huge SaaS platform.
One of the requirements was to provide a workflow engine and a web-based editor.Although there are commercial workflow libraries and editors out there, the business model required open-source software. We used WF and the re-hosted Workflow Designer. It worked, but it wasn't great.
五、源代码编译构建
项目源代码地址：https://github.com/elsa-workflows/elsa-core
通过VS2019，使用克隆的方式，将代码克隆到本地编译构建。
项目使用了Angular，在调试运行前，本地需要完成NPM包安装和JS 编译，所以本地需要先安装NodeJS
切换到XX\src\dashboard\Elsa.Dashboard\Theme\argon-dashboard, 执行NPM Install
安装过程中，涉及到Python相关的组件和环境变量配置，所以可能会安装失败，出现异常：
checking for Python executable "python2" in the PATH Can't find Python executable "python2.7", you can set the PYTHON env variable.
此时，先删除delete node_modules文件夹， 然后执行： npm install --global windows-build-tools
python组件安装完成后，执行以下命令：
npm config set python C:\Users\zhougq\.windows-build-tools\python27\python.exe npm install
