It's possible deatch instance imported?

Yes, the method you mentioned does what you need.

Also, your code snippet is missing a function with this method.

Yeh, I know.

Instance import is working, but I need to change for frameNode after import.

Thanks for the video, but I know how the “Detach instance” function works.

In this video, I didn’t see where the detachInstance method is used in your code.

As I understand it, it should be here:

Note that your prototype constant stores an array of InstanceNode, not the InstanceNode itself.

Now the last instance from the array will be detached, otherwise you will get an error on the last line.

Yeah.

I managed to do what I wanted, but I don’t know if this is the best way.

1const protoComponent = "id";
2      const importProtoComponent = await figma.importComponentByKeyAsync(
3        protoComponent
4      );
5
6      const instanceProto = importProtoComponent.createInstance();
7      block.appendChild(instanceProto);
8
9      const prototype = figma.currentPage.findAll(
10        (n) => n.type === "INSTANCE" && n.name === "name"
11      );
12
13      const lastPrototype = prototype[prototype.length - 1];
14
15      if (lastPrototype && lastPrototype.type === "INSTANCE") {
16        const newFrame = figma.createFrame();
17
18        newFrame.x = lastPrototype.x;
19        newFrame.y = lastPrototype.y;
20        newFrame.resize(lastPrototype.width, lastPrototype.height);
21
22        for (const child of lastPrototype.children) {
23          newFrame.appendChild(child.clone());
24        }
25
26        block.appendChild(newFrame);
27
28        lastPrototype.remove();
29      }

I don’t know why you abandoned the detachInstance method, but I would use it, with the error handling in the previous example.

Because it was wrong… but I checked and it was just a typing error \o/.

1Property 'detachInstance' does not exist on type 'SceneNode'.
2  Property 'detachInstance' does not exist on type 'FrameNode'.

Thank you again!
