Workflow of rendering <polymer-element>

[Oleksii Khliupin]

Hi,

Please, could someone to help with a topic.

I need to understand the workflow of rendering process in case when the native shadow dom is not available.

The most important place - When the root element is replaced with pre-rendered html?

thank you.

I'm not sure what you mean by pre-rendered html?

The basic idea of the SD polyfill is that each shadow host gets an associated renderer. When the logical dom is changed in a way that effects a renderer this renderer gets invalidated. Invalidated renderers get scheduled to be updated using requestAnimationFrame. You can also force all invalidated renderers to update synchronously by reading a property that depends on layout information, such as offsetWidth for example.

When a renderer is rendered it produces the composed tree (visual dom) which is what the browser uses to paint.
