Is there any way to check if a instance is up-to-date

What do you mean by update instances? Which API specifically can you not find?

When I use Figma for design, if a instance has a newer component version in team library, it show symbol like this:

And I was wondering if there a API that can check if a instance “can update”.

You know, for my Figma plugin development.

Unfortunately there is no direct API for that but it’s possible to do.

To find if instance is up to date:

• Get its main component ID and import it
• Check if importedComponent === instance.mainComponent
• If they are different, the instance can be updated

To update the instance:

• instance.swapComonent(importedComponent)

OK, let me try it later

It’s work!
I post my function code in case someone needs it

async function checkIfInstanceIsUpdated(instance: InstanceNode) {
    try {
      const asyncMainComponent = await instance.getMainComponentAsync()
      if (asyncMainComponent != null) {
        const importedComponent = await figma.importComponentByKeyAsync(asyncMainComponent.key)
        if (importedComponent != null) {
          return (importedComponent.id == asyncMainComponent.id)
        }
      }
      return null
    } catch (error) {
      console.log("error ! " + error)
      return null
    }
  }
  async function checkAndUpdateInstance(instance: InstanceNode) {
    try {
      const asyncMainComponent = await instance.getMainComponentAsync()
      if (asyncMainComponent != null) {
        const importedComponent = await figma.importComponentByKeyAsync(asyncMainComponent.key)
        if (importedComponent != null) {
          if (importedComponent.id != asyncMainComponent.id) {
            console.log("update")
            instance.swapComponent(importedComponent)
            return instance
          }
        }
      }
      return null
    } catch (error) {
      console.log("error ! " + error)
      return null
    }
  }
