SEO Meta Tags and Static Site Generation

Web Apps need to list detailed meta information about content in order to maximize SEO and provide good social media embed experiences.

One of the benefits to Rindo's prerendering is that most DOM apis are available in the NodeJS environment too. For example, to set the document title, simply run document.title = "Page Title". Similarly, meta tags can be set using standard DOM APIs as found in the browser, such as document.head and document.createElement('meta'). For this reason, your component's runtime can take care of much of this custom work during prerendering.

That said, the Prerender Config also includes options that allow individual pages to be modified arbitrarily during prerendering. For example, the afterHydrate(document, url) hook can be used to update the parsed document before it is serialized into an HTML string. The document argument is a standard Document, while the url argument is a URL for the location of the page being rendered.

In the example below, the afterHydrate(document, url) hook is setting the document title from url's pathname.

import { PrerenderConfig } from '@rindo/core';

export const config: PrerenderConfig = {
afterHydrate(document, url) {
document.title = url.pathname;
},
};
