I am a developer from Spain. I **have been building software for years** as a freelancer and contractor, helping startups ship their SaaS products, mobile apps and all kinds of projects. Below you will find a timeline with the products and open-source libraries I have launched, **the notable releases I ship for them**, and the changes to this site. ## Elsewhere - [X (@IAmAlbertAdler)](https://x.com/IAmAlbertAdler) - [GitHub (TheNaubit)](https://github.com/TheNaubit) - [Medium (@AlbertAdler)](https://medium.com/@AlbertAdler) - [Substack (albertadler)](https://albertadler.substack.com/) - [YouTube (@HeyAlbertAdler)](https://www.youtube.com/@HeyAlbertAdler) ## Latest posts - [How to update an expired Personal Access Token (PAT) in Git?](https://albertadler.com/blog/guides/how-to-update-an-expired-personal-access-token-in-git/) (2025-04-03): A quick guide to update an expired Personal Access Token in a non-destructive way using Git CLI. - [How to solve the ReferenceError Document is not defined issue?](https://albertadler.com/blog/guides/referenceerror-document-is-not-defined-react-router-7-mantine-cloudflare-workers/) (2025-03-30): The quick fix to make work React Router 7, Mantine and Cloudflare Workers all together. ## Timeline ### expo-stable-id v2.0.4: Expo SDK 58 support November 8, 2026 · Release v2.0.4 expo-stable-id now **supports Expo SDK 58**, with updated dependencies and the open security alerts resolved. In the same sweep I shipped maintenance releases for the rest of my libraries: make-url, color-to-hsla, react-aurora-background, tailwind-dot-grid-backgrounds, expo-cloud-settings, expo-native-toast and icon-composer-mcp. They bring dependencies up to date and fix every open security advisory.

Installs now go through Bun's supply-chain protections: a minimum release age and a security scanner on every install. The blog moved back from Notion to plain Markdown in the repo, so images never expire and there are **no build secrets** anymore. Every page now has a **Markdown twin** (append `index.md` to any URL), and there is an `llms.txt`, a full schema.org graph that ties the site to all my profiles, and a new generated Open Graph image per page. It scores 100 in every Lighthouse category and ships under 3 KB of JavaScript. ### Released astro-bun, a Bun-native Astro adapter October 19, 2026 · Launch I wanted to run Astro on **Bun without a Node compatibility layer in the middle**, so I built my own adapter for Astro 7. It is static-first, with opt-in SSR where you need it, and **opt-in ISR** with stale revalidation, invalidation helpers and a persistent SQLite cache. It also handles the server side properly: native static serving, Brotli/gzip precompression, TLS, Unix sockets, Linux worker supervision, SSE timeout controls, authenticated WebSocket endpoints and experimental HTTP/2. By v0.1.4 every release is published through **npm trusted publishing with signed provenance**, and the GitHub release is created automatically.

It pauses when off-screen, recovers evicted GPU contexts, follows page colors, and shows a still aurora when the user prefers reduced motion.

Size utilities now accept CSS variables and decimal opacity, and custom theme values generate valid utilities. The 1.x line stays available for Tailwind v3.

On iOS they are built with SwiftUI and **Liquid Glass** (and grow out of the Dynamic Island), and on Android they are a Material Snackbar. Each toast plays a semantic haptic and **announces itself to the screen reader**, because accessibility should not be an afterthought.

It arranges SVG or PNG artwork into layers, materials, fills and dark variants, and renders **native iOS and macOS previews in six appearances** using Apple's own renderer. It works with Claude Code, Claude Desktop, Codex, Cursor and VS Code, and ships with 58 automated tests and explicit workspace boundaries.

Contributions are welcome. [Check it out on GitHub](https://github.com/TheNaubit/awesome-react-native) ### expo-stable-id v2.0.0: now a pure JS module February 7, 2026 · Release v2.0.0 Removed the App Transaction ID feature (use `expo-app-integrity` for that) and dropped the native code, so the library is now **a pure JavaScript module**.

It has a hooks-first React API with change listeners, a config plugin so you don't touch Xcode entitlements, and an Android no-op so the same code runs on both platforms.

It keeps the ID in two places: iCloud key-value storage, so it syncs across devices, and the Keychain or Android Keystore, so it **survives app reinstalls**.

Sure, it works, but **managing images was a pain** and I wanted a better writing experience. So I decided to move the blog to use Notion as the CMS. Now I can write posts with a proper rich editor, upload images directly, and **focus on writing** instead of file management. So, basically, it fetches posts from Notion's API and transforms them for static generation. I also added proper categorization with **category-based URLs** like /blog/[category]/[slug]/ which makes much more sense (and hopefully more SEO friendly). I also switched to Shiki (well, I was not using any before, so not really a switch) and now code blocks look **much better** - with a header with the used language, a copy button, and support for tons of languages including Python, TypeScript, you name it. Finally, I fixed those annoying layout shifts when images load by fetching their dimensions server-side. **The little details matter** (plus Google Search Console was complaining about it all the time...) ### Moved to Astro March 30, 2025 · This site I decided to move this blog to Astro, now it is a static site, it does not ship any JavaScript and it is much faster. I am using Cloudflare Pages as a hosting service, making it free and even faster. Also, I am taking advantage of Astro plugins to generate things like sitemap, RSS feed and even the OG images for social media and even for accessibility (everything should be accessible now in this website). Finally, this allows me to just write the content in Markdown and not worry about the rest (I am also able to use MDX in case I want to use some components here and there). I am also playing with the idea of using some headless CMS in the future. ### Upgraded this blog to Next.js 15 & SSG February 1, 2025 · This site This blog was running on Next.js 14 and SSR in Cloudflare Pages but I felt it was a waste of resources since all the content was static. Since it was time to upgrade to Next.js 15 and React 19, I decided to also migrate it to be **fully static**. When using Cloudflare Pages for non-static sites, every request made to the server (even requests to static resources like images) **go first through a worker** so each page load could be much more requests than 1 for your free requests count in Cloudflare. I didn't like it so I decided to migrate to SSG and now the site is much faster and **it is basically free to run** since static resources are free to host in Cloudflare Pages. ### Built a boilerplate for SST v3, Next.js and SST Auth August 20, 2024 · Launch The project had the goal of showcasing how to use the new version of [SST](https://sst.dev) with Next.js and the new SST Auth library. I did this since right now, the new version of SST was launched, but **the docs for the SST Auth in that version didn't exist yet**; so I wanted to create a basic example for everyone until the official docs and examples were out. It was a fun adventure, **diving into undocumented source code**, testing, trying, breaking and trying again until it worked. But the efforts paid off and the result is here, a working example!

So I had the idea of looking for a Docker image already created for it in the Docker Hub. Sadly, the only image I found there was not really "production-ready". It had almost no security, **it was really outdated**, no logs... I thought about pushing an update to the repo but I saw that it was really inactive, with no one answering multiple issues and pull requests. So... I had to build my own one! At first, I thought about forking it and just update the stuff I needed. But it was more work than building it in the right way from zero. So now we have a new Docker image containing **a production-ready**, heavily optimized and secure web server containing a dashboard for monitoring Bull and BullMQ queues. It has lots of features like some basic authentication, CSP policies, privacy compliance, informative logs and it is running with Bun and Elysia, **for the best performance!** For all the details and also to check the documentation, feel free to check the GitHub repo (also I am open for contributions!): [Bull Board Dockerized](https://github.com/TheNaubit/bull-board-dockerized) P.S: It has some really nice GitHub actions so when I push to the main branch a new release, a new release is generated with semver version codes and then **a new multi platform Docker build** is published to Docker Hub with the semver and latest tags! [Check it out on Docker Hub](https://hub.docker.com/r/nauverse/bull-board) ### Created this site June 3, 2024 · This site With this entry, I started my new website. Although the design is not final (when is it?), I am trying to focus on making it minimalist and accessible. I like to build beautiful front-ends but everything has its time, and for this website, at least for now, I don't need a website with lots of animations, or cool effects... I just want a place where I can post little **articles about things I find interesting** and also a place where I can have a timeline showcasing my projects. And this version accomplishes both things. So we are ready to start. 🫡 ### Released color-to-hsla May 20, 2024 · Launch A tiny, **dependency-free** TypeScript library to convert any CSS color into HSLA.
