Calathea

Templates and rendering

Calathea uses the Tera templating engine. To combine Tera and HTMX, the template directory has the following structure:

• components contains components used to build views. Components are defined as Tera macros.
• views contains view templates that make use of the components.
• updates are templates returned from e.g. POST requests. Tbey usually directly wrap a component, e.g. a plant li item.
• base.html defines the skeleton for each page. Each view is rendered with this as its surrounding HTML.

When a page is requested from the server, it inspects the HX-Request and HX-History-Restore-Request headers to determine whether a full page should be returned or only the inner view. Using this, the server cn support direct routing to pages and caching properly while still supporting partial rendering using HTMX.
