 We've exposed the private server-to-server Storefront API token in the Hydrogen config file. This private token is required when deploying to production, otherwise the requests to the storefront API will be rate-limited. This change will make it easier to configure Hydrogen when deploying to non-Oxygen environments. We'll also display a warning in production mode if this token is not defined.

+  plugins: [hydrogen()],
+  resolve: {
+    alias: [{find: /^~\/(.*)/, replacement: '/src/$1'}],
+  },
+  optimizeDeps: {
