I’m working on a mobile app where offline-first is a real requirement (not just caching).The tricky parts are:
– optimistic updates
– temporary client IDs
– retryable request queues
– keeping UI responsive while syncing in the background
– avoiding tight coupling between networking and domain stateI’ve seen apps turn into a mess once these concerns start leaking everywhere.For those who’ve built offline-first mobile apps at scale:
– how do you usually structure this?
– what breaks first?
– what would you not do again?I’m experimenting with my own approach, but I’m very curious how others solved this in production.

Hello HN,I built Mindwtr because I wanted the speed and polish of apps like Things 3, but with the data ownership of Emacs Org-mode.It is an open-source (MIT&#x2F;AGPL), local-first implementation of the Getting Things Done (GTD) methodology.The Stack:
- Desktop: Tauri v2 (Rust) + React. It runs heavily on Arch Linux (my daily driver).
- Mobile: React Native (Expo) on Android.
- Sync: It treats the file system as the source of truth. Data is stored in JSON&#x2F;TOML, allowing you to sync via Syncthing, Dropbox, or Git.Key Features:
- &quot;Copilot&quot; Capture: Uses local regex and logic to auto-tag contexts&#x2F;projects as you type.
- Privacy: No cloud servers. Your data never leaves your device unless you sync it yourself.
- AI Hooks: Optional integration (BYO Key) to break down vague tasks or review stale lists, but completely functional offline without it.I am a PhD student and this has been my side project to manage my own research chaos. I&#x27;d love feedback on the architecture or the workflow.Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;dongdongbh&#x2F;Mindwtr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dongdongbh&#x2F;Mindwtr</a>

I&#x27;m a solo webdev working on a simple multiplayer game site. My tech stack consists of a Next.js frontend and node.js backend. I use socket.io to handle multiplayer interactions.As the title implies, I want to make a mobile app for the site. I was looking into React Native at first, but then learned about webviews from this great blog post by Puzzmo[0]. Webviews seems appealing because I would be able to reuse many existing components (though I am aware of next.js related challenges from having to export a static build) and be able to stay comfortable and productive™ in a webdev context. I don&#x27;t mind losing that &quot;native&quot; mobile UX goodness either since the tradeoff of better DX seems worth it given that I&#x27;m working on this alone. There also seems to be some neat tooling for webviews to streamline the development process e.g. Capacitor by Ionic[1].Anyone have any opinions&#x2F;insights&#x2F;horror stories on all this?[0] https:&#x2F;&#x2F;blog.puzzmo.com&#x2F;posts&#x2F;2025&#x2F;06&#x2F;01&#x2F;ios-app-architecture&#x2F;[1] https:&#x2F;&#x2F;capacitorjs.com&#x2F;

For the last two weeks, I was struggling to make Agents SDK work with React-Native. The problem is they never made support for it. After two weeks of trying different approaches, using a server as a proxy, or trying to make my own web socket, I almost gave up. Then I decided to do a little bit of digging and found out that actually someone in July tried to propose a PR with a fix to make React-Native work with Agents SDK. However, the maintainers ghosted that PR. After some digging, I have made my own patch, and successfully made Agents SDK work with React-Native.Secondly, I&#x27;ve reached out on every platform possible to both maintainers for the Agents SDK repository, and finally got a response through Instagram, surprisingly.The lesson is that I&#x27;ve learned is:
- I can patch any open source library to make it work for my purposes. 
- Second, as a nobody, you can reach out to people through many, many channels, and they will respond to you through one of them.P.S. It&#x27;s a TestFlight App, so you might wanna open it on your iPhone.

Hey everyone! I just built a mobile app using Expo (React Native) for a platform that moves $6M&#x2F;month. It’s a neobank used by 6,500+ nonprofit organizations across the world.One of my biggest challenges, while juggling being a full-time student, was getting permission from Apple&#x2F;Google to use advanced native features such as Tap to Pay (for in-person donations) and Push Provisioning (for adding your card to your digital wallet). It was months of back-and-forth emails, test case recordings, and also compliance checks.Even after securing Apple&#x2F;Google’s permission, any minor fix required publishing a new build, which was time-consuming. After dealing with this for a while, I adopted the idea of “over the air updates” using Expo’s EAS update service. This allowed me to remotely trigger updates without needing a new app build.The 250 hours I spent building this app were an INSANE learning experience, but it was also a whole lot of fun. Give the app a try, and I’d love any feedback you have on it!btw, back in March, we open-sourced this nonprofit neobank on GitHub.

Hey HN, and happy new year!I&#x27;m Hampus Kraft [1], a 22-year-old software developer nearing completion of my BSc in Computer Engineering at KTH Royal Institute of Technology in Sweden. I&#x27;ve been working on Fluxer on and off for about 5 years, but recently decided to work on it full-time and see how far it could take me.Fluxer is an open source [2] communication platform for friends, groups, and communities (text, voice, and video). It aims for &quot;modern chat app&quot; feature coverage with a familiar UX, while being developed in the open and staying FOSS (AGPLv3). The codebase is largely written in TypeScript and Erlang.Try it now (no email or password required): <a href="https:&#x2F;&#x2F;fluxer.gg&#x2F;fluxer-hq" rel="nofollow">https:&#x2F;&#x2F;fluxer.gg&#x2F;fluxer-hq</a> – this creates an &quot;unclaimed account&quot; (date of birth only) so you can explore the platform. Unclaimed accounts can create&#x2F;join communities but have some limitations. You can claim your account with email + password later if you want.I&#x27;ve developed this solo, with limited capital from some early supporters and testers. Please keep this in mind if you find what I offer today lacking; I know it is! I&#x27;m sharing this now to find contributors and early supporters who want to help shape this into the chat app you actually want.~~~Fluxer is not currently end-to-end encrypted, nor is it decentralised or federated. I&#x27;m open to implementing E2EE and federation in the future, but they&#x27;re complex features, and I didn&#x27;t want to end up like other community chat apps [3] that get criticised for broken core functionality and missing expected features while chasing those goals.I&#x27;m most confident on the backend and web app, so that&#x27;s where I&#x27;ve focused. After some frustrating attempts with React Native, I&#x27;m sticking with a mobile PWA for now (including push notification support) while looking into Skip [4] for a true native app. If someone with more experience in native dev has any thoughts, let me know!Many tech-related communities that would benefit from not locking information into walled gardens still choose Discord or Slack over forum software because of the convenience these platforms bring, a choice that is often criticised [5][6][7]. I will not only work on adding forums and threads, but also enable opt-in publishing of forums to the open web, including RSS&#x2F;Atom feeds, to give you the best of both worlds.~~~I don&#x27;t intend to license any part of the software under anything but the AGPLv3, limit the number of messages [8], or have an SSO tax [9]. Business-oriented features like SSO will be prioritised on the roadmap with your support. You&#x27;d only pay for support and optionally for sponsored features or fixes you&#x27;d like prioritised. I don&#x27;t currently plan on SaaS, but I&#x27;m open to support and maintenance contracts.~~~I want Fluxer to become an easy-to-deploy, fully FOSS Discord&#x2F;Slack-like platform for companies, communities, and individuals who want to own their chat infrastructure, or who wish to support an independent and bootstrapped hosted alternative. But I need early adopters and financial support to keep working on it full-time.I&#x27;m also very interested in code contributors since this is a challenging project to work on solo. My email is hampus@fluxer.app.~~~There’s a lot more to be said; I’ll be around in the comments to answer questions and fix things quickly if you run into issues. Thank you, and wishing you all the best in the new year![1] <a href="https:&#x2F;&#x2F;www.linkedin.com&#x2F;in&#x2F;hampuskraft" rel="nofollow">https:&#x2F;&#x2F;www.linkedin.com&#x2F;in&#x2F;hampuskraft</a>[2] <a href="https:&#x2F;&#x2F;github.com&#x2F;fluxerapp&#x2F;fluxer" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;fluxerapp&#x2F;fluxer</a>[3] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46376201">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46376201</a>[4] <a href="https:&#x2F;&#x2F;skip.tools&#x2F;" rel="nofollow">https:&#x2F;&#x2F;skip.tools&#x2F;</a>[5] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=40533484">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=40533484</a>[6] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=37502258">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=37502258</a>[7] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39569843">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39569843</a>[8] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46383675">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46383675</a>[9] <a href="https:&#x2F;&#x2F;sso.tax&#x2F;" rel="nofollow">https:&#x2F;&#x2F;sso.tax&#x2F;</a>
