Thanks @MisterKeyboard for providing the JSON. Your project contains 10K style rules, which is a lot, but still, I'd not expect the load to be impacted that much. @mohamedsalem401 I think we need to verify if data source related changes (e...

For your case, I'd suggest creating a custom block manager where you can adapt the UI for your blocks as you wish (eg. search, DOM virtualization, etc.)

pvbergen

Huh, that would be surprisingly simple. Thanks! I'll test it out in the next few days and see how we can integrate it with our workflow.

artf

If you open Chrome's "Performance monitor"...

varadero

This is important. If not fixed, it makes GrapesJS dangerous to use especially in SPA applications.

artf

I'll check it out, but any help is welcome

diazemiliano

[Editor UI]: Replace the current View for the core editor UI components

Hi there! the currently used structure of grapesjs is based on leveraging backbonejs model-view concept for implementing the Virtual Dom inside the ecosystem of grapesjs. Virtual Dom is a great practice which has a vast area of applications and benefits; but the downside of virtual dom is the actual gap between virtua...

artf

Yes @lexoyo the final goal here would be to stop relying on Backbone's View and migrate all editor UI elements to web components. In the end, there will be @grapesjs/core (no UI) and @grapesjs/core-ui with a set of reusable and extendable...

lexoyo

Ok that's interesting :) I can't wait to see that and i will contribute as much as i can

lexoyo

Nice idea I use lit-html quite lot, it's the same approach but also adds web components when/if needed But i don't get where would backbone stop? And what would be without it. I guess it is a question that is broader about what @artf annou...

artf

You can't use SSR on GrapesJS

symmetrically

@artf We are not rendering GrapesJS server side. It is compiled with asset pipeline where it breaks causing the other server side rendering to go down as well.
