The ComposerPostPreview component renders Markdown as HTML using the TextFormatter library, polling a data source for changes every 50ms. This is done to prevent expensive redraws on e.g. every single keystroke, while still retaining the perception of live updates for the user.

Attrs

  • composer The state of the composer controlling this preview.
  • className A CSS class for the element surrounding the preview.
  • surround A callback that can execute code before and after re-render, e.g. for scroll anchoring.

element

element: Element

The root DOM element for the component.

state

state: undefined

Class component state that is persisted between redraws.

Updating this will not automatically trigger a redraw, unlike other frameworks.

This is different to Vnode state, which is always an instance of your class component.

This is undefined by default.

updateInterval: undefined | Timer

Methods
