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 D…

HN discussionYjs is nice. Easy to get p2p results. Yjs backend, its persistence, eventual conflict resolution (one of editors stayed too long offline), history rewind seems like a tough engineering challenge to crack. Always wanted to have a nice experience with block editor like Platejs https://platejs.org/ There are nice attempts simplify dev experience with solutions like Liveblocks https://liveblocks.io/text-editor However m…

HN discussionWow, Sacha! 10 years already. Meteor was one of the first Javascript frameworks which gave me joy. Maybe the closest to that today is Imba. Realtime all the time was performance heavy for sure but so much fun. I recently saw https://liveblocks.io/ which is trying to do realtime primitives for the current wave. Discover Meteor was one of the first "modern" programming framework books I bought and I still remember the…

HN discussionI know Liveblocks.io has been making this very easy and accessible over the last few years. They recently introduced AI, and are promoting that of course, but as I understand it multiplayer collaboration ( https://liveblocks.io/multiplayer-editing ) is their meat and potatoes. Not affiliated with Liveblocks, just aware of its existence.

HN discussionGood question! There are still a lot of specialized editors that are not text-based nor collaborative yet. In the creative space, we can imagine 3D collaborative editors (think Figma but for 3D). Here is an example built with liveblocks: https://liveblocks.io/examples/3d-shoe-builder Filling a form can also be a collaborative experience: https://liveblocks.io/examples/collaborative-logo-builder Building a form can a…

HN discussionFrom our experience, live cursors positioning depends on the use case and the content behind them. For a "canvas app" (like Figma), the positioning will be absolute with an offset depending on the panning. For a responsive website, if it makes sense to add live cursors, it depends on how the content "flows". For example, if your content scrolls vertically and is centered horizontally, you can use percentage on the "…

HN discussionHi! Great questions :) Liveblocks does not come with a specific UI. We're providing APIs to create rooms and share states between users. The state can be volatile (like cursors, focused input, selection) or persisted even when the session is over, like a figma file or a google document (this part is still in private beta). We're using custom CRDTs for the persisted state. We only have a javascript client and react c…

HN discussionHi Gys, co founder of Liveblocks here! Our goal is to help companies create collaborative products like Figma or Google Docs with API and guides. Multiplayer infrastructure and conflicts resolutions can be challenging to build in-house and we think it will become a commodity (like logging or analytics systems). If our marketing video didn't convince you, maybe our examples page and documentation will give you more i…

HN discussionReally impressive experience! Great work Next.js! Love the work 0xcaOa did with Three.js to create this multiplayer light effect. Glad to see https://liveblocks.io was able to help them prototype this out to get a feel for that experience. And… it’s great to see the web become a place where people can hang out and feel like they’re together in the same space!

HN discussionAbsolutely! 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. 0: https://liveblocks.io/
