What is the difference between created and mounted requests in vue?

When making a network request in Vue, the mounted hook should be used because it ensures that the component is fully rendered in the page and can interact with the user, while the created hook is not suitable for this purpose because the component's DOM has not yet been mounted. load.

The difference between created and mounted requests in Vue

In the Vue life cycle, created and mounted are two key hooks used to perform specific initialization tasks. However, the difference between using these two hooks is important when you want to make network requests after the component is mounted.

created

created The hook is called after the instance is created and properties and data are observed, but before the DOM is mounted. This means that at this stage, the component's DOM elements have not yet been added to the page.

Sending a request: Initiating a request in a created hook may be too aggressive. Because the DOM has not yet been mounted, the requested results may arrive before the component is actually displayed, causing potential flickering or inconsistencies.

mounted

mounted The hook is called after the component DOM is mounted and can interact with the user. At this point, the component is fully rendered and the results of the request can safely update the DOM.

Sending a request: Initiating a request in a mounted hook is a more appropriate time to initiate a network request, as it ensures that the DOM is ready to handle the result of the request.

Summary

• created The hook is not suitable for making network requests because the component's DOM has not yet been mounted.
• mounted Hooks are the preferred time to make a network request because the component is fully rendered in the page.
