I’m now on GitHub Sponsors. I’ve been building Inbox a privacy-first personal note-taking system with Telegram bot integration, voice transcription, and calendar sync. Runs on a Raspberry Pi. If this project makes your life easier, you can support its ongoing development. github.com/denisfl/inbox

denis.leaflet.pubWhy I built Micra.js

micrajs.devMicra.js — reactive UI for server-rendered appsA 7 KB reactive UI library that drops into any server-rendered app. Reactive state, components and directives — no build step, no SPA.

Shipped micrajs.dev 2.7.0 yesterday — better @htmx.bsky.social support in it. A few thoughts on htmx itself: what it's good at, how it works, and where it has a gap.

For a large class of apps — CRUD, admin panels, dashboards, forms — that's enough, with no separate front end. htmx's gap is the state that lives only in the browser: whether a dropdown is open, a form draft, the active tab.

The server doesn't need it. That's the seam Micra fills: htmx delivers the markup, Micra holds the local state on top. In 2.7.0 the wiring is three lines — mount on swap-in and one autoCleanup() for teardown.

The browser already did server-driven UI — through links and forms, but those replace the whole page. htmx lifts that limit: any element can send a request, with any method, and the response replaces the piece of the DOM you point it at.

A whole layer goes away — no client model to keep in sync with the server. Behavior is written on the element itself: hx-get, hx-target, hx-swap are right there in the markup, no hunting for handlers across JS files (htmx's author has an essay on this — locality of behaviour).

I remember when jQuery sat on almost every site — just to reach the DOM. Then the frontend grew: React, Vue, Svelte. For good reasons, but not for everything. Plenty of sites are still simple: server HTML plus a little interactivity.

Change the state, the markup follows. No "look up the node by selector, poke style.display." Only the state changed. A switch works the same: a boolean in state, a method that builds the class string, one binding re-rendered on click. The same trick drives a dark-mode toggle.

Micra isn't a replacement for React, Vue, or Alpine — a tool for a narrow niche, ~7 KB, MIT. If htmx, Stimulus, Alpine, or something else fits better, use whatever fits your work.

For those, a full framework with a build step is a lot. And reaching for nodes by hand to mutate them gets old. I tried everything from Vanilla.js to React, and the tricks I kept reusing settled into one small thing. That's how micrajs.dev came about.

22 June

The idea is plain: you write ordinary HTML and mark it up with attributes. Classes stay for styling; data-* carry behavior — data-component (where a component lives), data-show (when to show it), @click (what to call).

I’ve added LLM benchmarks for github.com/denisfl/micr.... It’s clear that smaller models struggle to retain long specifications, but on ~90% of the typical solutions Micra was created for, the results are more than satisfactory. On frontier models, I expect solid perf. even for complex solutions.

I certainly wasn’t planning to write code on a Saturday evening, but it just sort of happened…

So it's time to say hello to Micra.js denisfl.github.io/micra.js/ — a reactive UI framework. Most pages don't need a 45 KB SPA framework. They're server-rendered (Rails, Laravel, Django) and just need a sprinkle of reactivity: modals, forms that validate, etc.

27 May

Benchmarks are live: denisfl.github.io/micra.js/ Still verifying whether my Alpine.js adapter is written correctly — but I tried to be fair and honest in comparison. Early results show Micra.js performing extremely well in reactive scenarios — especially list updates and state writes.

And here is the result coming soon 🚀

How is your weekend going?

Small quick win this week. It was an interesting task that I worked on.

В пуско-наладочном режиме начинаю тестировать онлайн мониторинг с алертами в телегу. Хочу за выходные допилить мелкие баги. Если кто хочет потестить на своих серваках, напишите.

So, I thought about it for a while and ended up rewriting everything in Go. Now it’s a proper cross‑platform solution. github.com/denisfl/sumi

Made a little monitoring setup for my Raspberry Pi, but it works on a Mac too. Just in case someone finds it useful. gist.github.com/denisfl/3001...

Working on how to integrate evergreen notes into my existing system. So far it’s all trial and error. The tricky part is that there are notes and there are documents. I don’t want to separate them as different entities, but merging them doesn’t feel quite right either.

18 Mar

Released a small batch of Inbox improvements. Mostly subtle refinements like better alignments and a cleaner calendar grid with the timeline.

Delivered new awesome UI github.com/denisfl/inbox

Being a big fan of 37signals, I borrowed their circular progress bar that shows how many tasks for today are done out of the total. I love noticing these tiny details that make an interface feel human. AI can’t invent things like that.

6 Mar

Switched my Inbox transcription from Whisper to Parakeet v3. The speed boost on a Raspberry Pi is insane — short voice notes now transcribe almost instantly.

5 Mar

I made some small design changes in the Inbox. It feels super cozy on mobile now.

4 Mar

Since yesterday, I released my open source solution that I use instead of Evernote, etc. Honestly I was big fan of Evernote and Obsidian for a long time, but I was needed to make some customizations. In one day I just got my Raspberry Pi and install RoR and configure Whisper for my needs.

And this made sense for me. The system collects information from multiple sources, processes it in the background, and presents everything through a clean web interface. github.com/denisfl/inbox

21 Feb

I haven’t taken any notes or looked at my to‑do lists for over a week. Now I’m just sitting here with a notebook and a pen, and my mind’s completely blank.

22 Jan

Instead of creating a native app I decided to use PWA.

19 Jan

Incomes section has been delivered this morning 🎉 Now you can see invoices incomes and add some income manually.

open.substack.comTrueNorth for Making Your Work VisibleSince December of last year, I’ve been working on a couple of projects that go hand in hand.

18 Jan

Wrote about TrueNorth on Substack open.substack.com/pub/denisfl/...

17 Jan

Yay, I finally put together a simple PWA 🎉 The hardest part is still ahead — coming up with an icon and actually drawing it. And yes, that’s exactly the part I’ll procrastinate on until the very end 🙈

17 Jan

It also supports keyboards shortcuts

16 Jan

Started working on new Create Invoice flow for True North. The first prototype was good, but had some limitations. So now I am trying to extend the flow.

14 Jan

Added quick task save to truenrth.app — just press Enter to reset the timer and start a new task. Tiny feature, but surprisingly satisfying.

12 Jan

Alright, here we go. The landing page still has AI‑generated text for now. There’s a lot to polish and refine. But one thing I’ve realized: it’s impossible to finish everything. truenrth.app is finally taking shape — slowly, quietly, but in the right direction.

11 Jan

Yesterday I spent a lot of time experimenting with handwriting recognition. So far the conclusion is this: my cat reads handwriting better. Cyrillic characters are recognized especially poorly. But as a challenge, it's incredibly engaging. Five hours flew by without me noticing.

The 2025 recap is ready. Running, projects, paper, guitar, and steady forward movement. open.substack.com/pub/denisfl/...
