how to add props to nodes?

[r6m]

Hi, I'm trying to handle RTL format. is there any way to do it?

I've come up with a solution, but I'm having trouble to do it:
adding dir to paragraph props just works (adds 'dir' attribute to the node in html):

createParagraphPlugin({ props: { dir: 'auto' } })

but it does not work on headings (does not add 'dir' attribute to the node in html):

createHeadingPlugin({ props: { dir: 'auto' } })

Because the heading plugin is composed of many plugins, you need to use overrideByKey: { h1: ... } }

thanks @zbeyens , saved a day. I used reduce to apply it on all headings

{ overrideByKey: KEYS_HEADING.reduce((acc, key) => ({ ...acc, [key]: { props: { dir: 'auto' } } }), {}) }
