Server-side rendering

Every pagepal entry point can be imported in Node, and createPal() can be called there. Without a document, the pal is inert:

• nothing renders, no listeners are added, and nothing is patched;
• every method still works: react(), on(), use() and destroy() don’t throw;
• pal.element is null, and pal.mood still tracks moods you set yourself.

So code like this runs unchanged on the server and the client:

import { createPal } from 'pagepal';

export const pal = createPal({ requests: true });

That said, a module-level pal on the server is shared by every request. In SSR frameworks, create the pal on the client instead: in an effect (the React and Vue components do this for you), a client-only plugin, or a <script> that runs in the browser.

Analytics on the server

analytics() installs nothing without a window, but summarize() is a pure function and is meant to run on the server, over the events you stored:

import { summarize } from 'pagepal/analytics';

const report = summarize(await loadEvents());
