Apostrophe refrains from loading most of its JavaScript and CSS for logged-out users. This is a good thing because it renders pages faster.
However sometimes those features are really useful for anonymous users. For instance, our apostrophe-moderator module lets the public submit new events, articles and so forth. That depends on the ability to present schema-powered forms and edit content the same way a logged-in user would.
To do that in your own code, just use the apos.requireScene method in your browser-side JavaScript code. The code in your callback is guaranteed to have access to all the JavaScript, CSS and DOM template assets that logged-in users see:
apos.requireScene('user', function() {
// Do great stuff like using `apostrophe-schemas` to process forms
});
It won't take long to for Apostrophe to load the extra assets and start running your callback. However, always make sure you have set minify: true in data/local.js on your production server so that your CSS and JavaScript are as compact as possible.
