How to use Elsa designer tree control

[GreenShadeZhang]

When I use Elsa designer tree, I find that some of its data comes from state, but I use it in some front-end frameworks, such as Vue, so how can I pass in the data in state, such as state.activitydescriptors, to ensure normal rendering?
If activitydescriptors are not included, an error will be reported.

Indeed. It would be better for the <elsa-designer-tree> component to directly accept things it's getting from state as properties, rather than getting from state.

Please feel free to open an issue for this, and even better, a PR that changes this.

Until then, what you might be able to do is simply include state from your own application and setup the state similar to the way the `elsa-workflow-definition-editor-screen- component does:

import state from '../../../../utils/store';
import {createElsaClient} from "../../../../services";

// From some "onload" method or whichever initialization method is applicable in your own framework:
const client = createElsaClient(''); // Provide URL to Elsa Server.
state.monacoLibPath = ''; // path to monaco lib.
state.activityDescriptors = await client.activitiesApi.list();
state.workflowStorageDescriptors = await client.workflowStorageProvidersApi.list();

When I use the latest NPM package 2.1.14, the rendering interface data activities lacks the outputs field. When I manually render an empty array, it is normal. However, some events given by < Elsa designer tree > are abnormal. I speculate whether it is because my background interface data is too old, resulting in some rendering exceptions, so some events will take effect. Activityselected is normal, and others do not respond. The Vue registration method I use should be OK. I'll try the method you give.

this.$refs.treeview.addEventListener(
    "activityContextMenuButtonClicked",
    (event) => {
      console.log(event);
      console.log("activityContextMenu Button Clicked");
    }
  );

  this.$refs.treeview.addEventListener("activitySelected", (event) => {
    console.log(event);
    console.log(event.detail.activityId);
    console.log("act select");
  });

  this.$refs.treeview.addEventListener("workflow-changed", (event) => {
    console.log(event);
    console.log("workflow-changed");
  });

  this.$refs.treeview.addEventListener("activityDeselected", (event) => {
    console.log(event);
    console.log("activityDeselected");
  });

When I check the source code related to the designer, I find that some tool classes in the utils directory do not have the index.ts file, that is, they seem not to be exposed. Is there any good way for me to use it?

We can export the functions from utils too. Do you want to submit a PR?

I found that the front-end UI of version 2.2 has made a lot of changes. I need some time to try to use it in Vue and solve the problems encountered in the use process. When I use it skillfully, I will improve some things. At that time, if I think it is easy to use for everyone, I will submit it to pr.

Sounds good. Thank you.
