liveblocks VS core

Absolutely! The real complexity comes from conflict resolution. If someone edits the top, and someone else edits the bottom, which version do you go with? What if they're editing the same area? Entire companies exist to provide elegant solutions to this[0], so it's no simple task.

I can imagine, browser extensions are a pain in the butt. Are you planning to open source the code? Did you build everything by yourself or on top of https://liveblocks.io/?

For the following example, I want the gradient color to flow from "Hello World" to the "Circle", so they are synchros and match the colors. I created this snippet but I'm having trouble with the rest. https://play.tailwindcss.com/accHTivCcx. Another example would be the https://liveblocks.io/'s title, which flows through the colors in the gradient. How would I achieve this?

Does anyone have any opinions about using Liveblocks for a live collaboration application as opposed to just using Firebase?

liveblocks is great for multiplayer state sync. i was able to make my canvas redux app collaborative in a couple of hours https://liveblocks.io

Very cool use case for CRDTs! I've seen a bunch of different use cases from other products like https://liveblocks.io/ and https://electric-sql.com/. It's interesting how CRDTs are now taking hold so much for all these collaborative syncing scenarios. Wonder what's driving the proliferation now given they've been around for awhile?

Hi Tim,

I'm a bit biased but https://liveblocks.io is great for that :)

If you know how to use React, that's pretty much all you need to know. It also includes some nice hooks to enable things like multiplayer undo/redo and live cursors.

The team even put a couple of interactive blog posts about that that you might find interesting:

True! I would also include https://liveblocks.io to that list of services that help developers make multiplayer experiences.

Interesting to see more players in this space to help more and more developers do this.

Hey, author here! Glad folks are enjoying this.

A few notes:

- I post a _lot_ about tldraw on Twitter. If you're curious about how this came together, or want to follow along as we ship new features, check out my timeline (https://twitter.com/steveruizok).

- The whole tldraw project is MIT licensed and open source (https://github.com/tldraw). And it's still in development! If you'd like to contribute, join the Discord channel (https://discord.gg/SBBEVCA4PG) or drop by the repo (https://github.com/tldraw/tldraw).

- The multiplayer is using a pre-release version of Liveblocks (https://liveblocks.io/)—and honestly isn't using it in a very clever way—and so can have some desync issues. Consider this part of the app an early beta.

- We also ship a Visual Studio Code extension that lets you use tldraw inside of VS Code! (https://marketplace.visualstudio.com/items?itemName=tldraw-o...)

A little more about the project itself:

The tldraw project has a few different layers.

At the bottom, there is a renderer named @tldraw/core (https://github.com/tldraw/core) that is essentially a "put React components on a canvas UI" engine. You give it a data model along with a set of utilities to interpret that data model. Simple but very fast, very flexible, and packed with helpers for building these kinds of apps. It's already being used for some pretty ambitious projects apart from tldraw itself.

The main library, @tldraw/tldraw (https://github.com/tldraw/core), exports the whole tldraw "app" as a React component named . This component can be embedded in any React project. It can be controlled either by props or by its own API (ie `app.selectAll().duplicate()`).

The website is a very thin Next.js app that embeds the component.

There are also a few other libraries: @tldraw/vec for the vector math and @tldraw/intersect for intersections. If you like to work on these kinds of projects, definitely bookmark those libraries! They contain a lot of useful code.

As for its development, I've taken off a few months between jobs to work on this full time. Until now, the site has been accessible only to my Github sponsors, but it's now free and open to everyone. If If you'd like to support the project's continued development, you can sponsor me here: https://github.com/sponsors/steveruizok.

I'll answer questions here but if you want to contact me directly, my DMs are open @steveruizok.
