Vue is removing a DOM node during the created lifecycle hook to set up a component

I am currently working on understanding the issue with this example that is not behaving as expected. My goal is to initialize my ContentView using the server-side rendered HTML in the DOM. I plan to check if init__main-content exists and then initialize the component with its innerHTML. However, when attempting to delete the initial node, the content ends up displaying twice.

I believe there may be some Vue "magic" at play here that I am unfamiliar with. Can someone please explain this behavior to me?

Answer №1

It seems like there might be an issue in your code where you are utilizing the created hook instead of the mounted hook.

After mounting, Vue completes all of its operations on the DOM, allowing for any changes to be saved into the DOM structure.

If you use the created hook, Vue may interpret the inner HTML as a template and try to re-render it onto the DOM, assuming that the previous HTML doesn't match the current HTML upon instance creation. This could cause unexpected behavior if you are already removing that particular element. By using the mounted hook, your application should function properly. Give it a try!
