Bart Blast

This week in the Hologram Showcase: Combat Log by Dillon O'Connor, goal tracking and reports for software teams. He started it on LiveView, then clicked around the Hologram website, found that it felt instant, and moved his app over page by page. hologram.page/showcase/com...

Usually I'm the one on stage talking about Hologram. This November it's someone else, and that feels great :) @jamauro.bsky.social is speaking at ExMex in Austin, Nov 12-13: "The Future of Full-Stack Elixir: Building Local-First Apps with Hologram". Details and tickets in the replies.

The first project in the Hologram Showcase is... Hologram's own website :) 62 pages, 96 browser tests, and every page I add to it is a test of the framework. It's also the first chance to see what a Showcase entry looks like: hologram.page/showcase/hol...

Apps shouldn't pay for features they don't use. Hologram's local-first data layer is on the way, and this week I made sure an app without a data model gets none of its code. The compiler's whole obsession is shipping as little as possible. Dozens more ideas lined up :)

Most Elixir devs I talk to already know about Hologram. But before they give it a try they want to see who else is using it and what's possible. So I'm starting a Showcase! If you've built an app with Hologram or a library for it, I'd love to have it there: hologram.page/showcase/sub...

Small confession. Smaller bundles in Hologram v0.12 took me two tries. The first was a 12,600-line data flow analysis. I threw it away. That hurt a bit... What shipped just checks what the server sends. On a 9,000-module app the runtime went from 5.6 MB to 660 KB, 133 KB gzipped in production :)

Hey Elixir friends! :) Hologram v0.12 is out, now with much faster compiles and much smaller bundles. It builds a 9,000-module app that v0.11.1 ran out of memory on, and that app's runtime bundle went from 5.6 MB to 660 KB, 133 KB gzipped in production. hologram.page/blog/hologra...

Last week at Goatmire Elixir I showed a local-first app in pure Elixir on a theatre stage from 1895. I stayed in a hotel with 15,000 books and a spa named after Lenin, and came home wanting to play with hardware. Thank you @lawik.bsky.social and Stina for organizing it! New Hologram release soon :)

Hey Elixir friends! :) My ElixirConf US talk "Hologram: Building Local-First Apps in Pure Elixir" is live. A trip planner goes offline in one window, then catches up. How it works: the compiler works out what each page syncs, and edits merge per column, no CRDTs. www.youtube.com/watch?v=jdg_...

Hey Elixir friends! :) Hologram v0.11 is out, now with Elixir regexes running in the browser and client errors that read exactly like server errors, stacktraces included. Plus dynamic tags, attribute and prop spread, and umbrella support. hologram.page/blog/hologra...

Hey fellow alchemists! @mikehostetler.bsky.social built a Slack clone with Jido and Hologram - agents and people in the same rooms, UI in Elixir running in the browser. Great writeup, and exactly what I hoped Hologram would be used for :) jido.run/blog/jido-as...

I was on the BEAM There, Done That podcast, talking Hologram with Francesco Cesarini and Allen Wyma. Francesco called the idea "Joe Armstrong stubborn" - the browser speaks JavaScript, I made it speak Elixir instead. Happy to own that :) www.youtube.com/watch?v=BOsS...

Hey Elixir friends! :) I just published a post that matters more to me than most - where Hologram's funding stands, what sponsorship built this year, and why what comes next depends on a few companies stepping in. hologram.page/blog/backing...

Yesterday I wrote the first line of code for Hologram's Local-First data layer. After months of research instead of code, that felt good :) Heads-down for 2-3 weeks now, so I may be slow on bug fixes. Epic: github.com/bartblast/ho... Branch: github.com/bartblast/ho...

Hey Elixir friends! :) My ElixirConf EU 2026 talk is online. Hologram lets you build a whole web app in pure Elixir, front end included. This one is about the next chapter - local-first - and why Elixir has an edge JS stacks can't copy. www.youtube.com/watch?v=qqpN...

Recently, I got attendee feedback for my ElixirConf EU talk about Hologram, the full-stack web framework I'm building that runs your Elixir code in the browser. One of the comments: "Bart Blast seems like a man on a mission, and we are along for the ride." You bet I am! Glad to have you along :)

Most frontend code isn't UI. It's data plumbing - caching, syncing, loading states, and more. Hologram's new Local-First data layer takes it over: declare what the data should be, it syncs itself in the browser, offline included. Pure Elixir. Teaching it hands-on at ElixirConf US, Sept.

Soon I start building the most ambitious thing I've attempted with Hologram (my full-stack Elixir framework): the Local-First data layer. Your app keeps its data locally, syncs in the background, and keeps working offline - all of it written in Elixir.

Hey Elixir friends! :) Hologram v0.10 is out, now with a real event system. To show it off, I rebuilt Space Invaders in pure Elixir, running in the browser with no game engine. There's a new server-side middleware layer too. hologram.page/blog/hologra...

After going quiet for way too long, the monthly newsletter for Hologram (my Elixir web framework) is back. Shorter issues now, tied to the release cycle so it should stick this time. First one's out next week: hologram.page/newsletter
