React Miami

Let's run it back!! Tickets for React Miami 2027 officially on sale now! Lock it in: tickets.joinshowup.io/event/n-a-5isf…

Congratulations again, @_christinacodes, on your first ever conference talk! It was inspiring 👏

'React Router v8 and Beyond' from the incredible @BrooksLybrand of @Shopify

We asked developers: what are you excited about right now? @ReactMiamiConf

React Miami's first ever Spanish talk, 'El futuro de React es ahora', delivered by the incredible @midudev!

How are developers upskilling now that everything is changing? We asked at @ReactMiamiConf, and the answers weren't what we were expecting to hear.

This year's impactful keynote delivered by @aurorascharff on 'Designing the In-Between States with Async React'

The iconic React Miami shirts designed again this year by our talented friends at @basementstudio 🔥

inspired by @_christinacodes' talk at @ReactMiamiConf, i built this website for my mom and my wife. thank you @_christinacodes for reminding us devs why we started doing software in the first place.

@ReactMiamiConf genuinely one of the most fun conferences I’ve attended. Met some super cool people after being pretty isolated over in corporate big tech for a while. Still looking to keep that momentum and connect with more women in tech 💕

Outstanding job by the whole @g2i_co crew at @ReactMiamiConf for organizing such an amazing event. I highly recommend it for learning and networking with some of the best React developers in the community. Will definitely be back next year 🫶🏼 Peace out.

This the level of joy @ReactMiamiConf brings

Massive thank you to our small but powerful team of volunteers! We couldn't have done this without you! A special shout out to @lrusinou, our Head of Volunteers, whose been helping since the first ever React Miami!

The people are truly what make React Miami so special - not their job title but the amazing energy and positivity they show up with!

Hallway? You mean runway? 💅

As promised, yapping more on @jazz_tools After launching the v2 alpha at @ReactMiamiConf our focus has been polish and perf, and there is a lot to do. Often, refactoring and nailing down semantics go hand in hand with performance. We realized this again over the last couple days, working on clarifying the difference between “batches” and “transactions”. Jazz v2 is unique in that it offers both globally consistent MVCC-style ACID transactions as well as local-first, eventually consistent writes (this is actually the default). But then we realized that even for the eventually consistent writes, it sometimes makes sense to group them into units, which we called “batches”. Initially, we thought of this as a pure perf optimization primitive and were quite loose with their semantics compared to transactions, where strictness really mattered. For example, in transactions you clearly want all-or-nothing and rollbacks, but we didn’t really think this was important for batches. But then, trying to actually implement the perf optimizations, we realized that per-row bookkeeping in large batches made them basically pointless. So perf guided us towards a clearer meaning for batches: they should also be all-or-nothing, now only being separated from transactions by one clear distinction: multiple concurrent batches can all be accepted and participate in merge-previews, while only one of multiple transactions gets accepted, resulting in global consistency and linearizability. With all the rows per batch sharing one fate, the bookkeeping overhead disappears and the decision for which tool to use in each case becomes crisp: - eventual consistency ok but need operations to have truly independent fates? Use separate batches. - eventual consistency ok and operations sharing fate ok or even desired as a logical unit? Use one batch. - need global consistency? Use a transaction. It’s fun to see how this loosens up complexity throughout storage format, query subscription updates, sync protocol etc.

React Miami wouldn't exists without our Founder, @gabegreenberg! Thank you for everything you do for our incredible community!

I love this because it all comes down to being around amazing people at a conference like @ReactMiamiConf and everyone in the video emphasized that.

Honored to have @sethwebster, Executive Director of the React Foundation, make a surprise appearance and talk about the future of React 👏
