Incrementally hydrating editor state based on visible nodes

[runnedrun]

Hi! I have an application that stores fairly large documents (about 4000 lines of text). In order to make things smaller and faster I store each "line" as it's own entry in my DB that has it's own foreign key, and then I display each line as it's own LineNode in Lexical, which a foreign key pointing to the line in the DB. When saving my Lexical EditorState to my DB I replace each line with a simple reference to it's foreign key. Now, I don't want to hydrate all 4000 lines at once when I load the document the first time, instead I'd like to hydrate each LineNode with it's corresponding text, from my DB, when the node is scrolled into view.

I have this kind of working right now, but it feels quite hacky. Are there any examples or plugins that can help with this? Thanks!

Have you figured it out?
What's wrong with "just" appending the next line to the editorState? Not sure what you're doing but maybe you'd need to actually place something like DecoratorNodes as placeholders with the line.id and then replace with actual node and content once its time comes so that people can already start editing, maybe even make your placeholder nodes non-removable, (this might help)
