Tips for NUXT

This is a plugin that works only on the client side. So please register it as a ssr-free plugin.

Usage

Please refer to the examples folder for details on usage using dynamic import.

Rehydration

Torus uses window.sessionStorage to store user details.

So, if the user reloads the page, all his data would be rehydrated and the user doesn't need to log in.

The samples provided in the examples folder illustrate the above case.
