How to develop an uploadable theme template function?

[the-content]

I am developing an e-commerce system for a client. How can Payloadcms design a backend that can switch the front-end theme template, just like the theme switching of WordPress. The backend can directly change the front-end template theme. For example, the backend creates a theme switching configuration page, and then you can upload the packaged front-end nextjs build code and upload it. It also includes a theme configuration file, such as theme.json, which contains the theme thumbnail preview and theme name. The backend can display all the information of this theme, just like WordPress displays a thumbnail and an installation button, and then clicks on the installation and use, the front-end theme will change. How to design such a function, and how can the front-end dynamically switch according to the theme selected by the user? I found a website that seems to have implemented similar functions, but it is not open source: https://cornerrr.com

Cool project!!!

You can take inspiration of the multi-tenant template/plugin of payload.
https://payloadcms.com/docs/plugins/multi-tenant

For setup, create a kind of global where you define the settings of a tenant.
It is also possible to add an upload field where you only accept JSON.
And in a hook on upload read the JSON and update the settings accordantly.

Where can we follow your progress?
