The latest update includes a new way of connecting your local host to Pages that simplifies and accelerates the front-end development workflow. Starting from JSS version 22.1, you can connect to Pages using the metadata approach, which gives you the following benefits:
Eliminating the need for tunnelling using Ngrok and complex CORS configurations.
Allowing easy use of an external editing host with your hosting provider (such as Vercel).
Faster editing experience when working locally with Pages.
If you are using the latest version of JSS, metadata is the default experience. Simply connect your local host to Pages and start developing.
