Lifecycle

Symbiote-component - is an extension of a native Custom Element, so it has all regular native lifecycle stages:

Additional lifecycle callbacks

renderCallback() - is a most regular and convenient place to describe component's logic:

class MyComponent extends Symbiote {
 
  renderCallback() {
    // You have an access to data and to the all DOM API methods here
  }

}

If you DO NOT planning to permanently remove your component from DOM and destroy it - set readyToDestroy property:

class MyComponent extends Symbiote {

  readyToDestroy = false;
  
}

Otherwise, component will be destroyed in case of DOM detachment, if you will not return it back with a synchronous DOM API call.

Than means, that you able to take Symbiote component from the one place in DOM and move it to another place synchronously (f.e. for the list ordering), without any additional action from your side.
