volto-base

A common place to put Volto common stuff. A replacement for the Volto server providing a builtin CORS proxy.

To use it, replace your index.js with:

import start from 'volto-base/start-server';

const reloadServer = start();

if (module.hot) {
  reloadServer();
}

In the config.js file, add a new key to the settings variable, named allowed_cors_destinations. This is an array of strings, each string being a hostname that will be allowed as proxy destination. For example, to allow embedding files from the eea.europa.eu domain, set the settings like:

settings.allowed_cors_destinations = ['eea.europa.eu']

Another option is to provide a system environment variable named ALLOWED_CORS_DESTINATIONS, which is a list of comma separated hostnames.
