Show HN: Automate Expo QR Code Previews in GitHub PRs https://ift.tt/Ezs9TIu

Show HN: Automate Expo QR Code Previews in GitHub PRs Hey HN, Inspired by Vercel’s automated preview deployments, I built a GitHub Actions workflow that generates an Expo QR code per PR—so mobile previews are as easy as scanning a QR code. How it works: • Every PR triggers a GitHub Action • The action starts an Expo server • It posts a QR code in the PR comments for instant testing on mobile No more manually starting Expo. No more copying links. Just open a PR and scan the code. Full guide here: https://ift.tt/jF1ZlQM Would love to get feedback—how would you improve this workflow? https://ift.tt/jF1ZlQM February 17, 2025 at 10:03PM

Show HN: Hackyournews.com v2 https://ift.tt/oHhIwvF

Show HN: Hackyournews.com v2 A year and a half after I published https://ift.tt/7tSDiYc , I've rewritten it to be neater and added support for more news sources. HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors. There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries. This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going! Someday, I hope to use the Batch API [2] to drive down costs even further. Enjoy. [1] https://ift.tt/GmcSjfV [2] https://ift.tt/lJ6LGxj February 16, 2025 at 06:16AM

Show HN: I got frustrated with CRMs, so I'm building my own for startups https://ift.tt/yhHEwCi

Show HN: I got frustrated with CRMs, so I'm building my own for startups After trying a bunch of CRMs for my startup, I kept running into the same issues—overpriced plans that scale aggressively or bloated features that just slow me down. I wanted something simple, affordable, and actually built for startups, so I decided to build it myself: Leadchee.com. Fixed pricing, no nonsense. Curious—how do you all handle CRMs? Do you stick with the big players, go for niche tools, or build your own? Would love to hear your thoughts! https://leadchee.com February 14, 2025 at 09:25PM

Show HN: Open-Sourcing My LLM Drag and Drop Website Builder https://ift.tt/Q0StYNc

Show HN: Open-Sourcing My LLM Drag and Drop Website Builder Hey HN - OP here. I wrote some about this project in the following link, and there's a video demo as well: https://ift.tt/456gJcz... This has been one of my favorite things I've ever worked on - the way the LLM collaborates with the user to accelerate tedious and hard work, the way you can directly edit the code instead of dealing with a panel of visual editing toggles - I think it has a lot of potential but I don't have time to pursue it anymore so open-sourcing it. The idea for this came out of conversations with a few people who were struggling with frontend development. For technical people, strictly using an LLM to write code can be tedious. To combat this, LLM usage is limited to getting started quickly, improving design, and wiring up frontend state. On the other hand, writing frontend code feels less efficient than just moving things around on a screen. Hence the drag and drop interface that makes it fast to build. Finally, I despise the visual editing toggles on Figma / Bubble / Squarespace / etc. The amount of hunt and peck to simply adjust a font a bit and change some colors or add a shadow is a huge time suck. So I built a way to directly edit the underlying React code when styling - just add or remove tailwind classes. IMO the craziest thing is that all of the code is just stored on the frontend in a config language of sorts. It is inflated at runtime and can be updated without any hot reload. There is no "underlying React code" for the app you're building here - in order to edit the code, I convert the config into React code, then convert back to a config, which triggers updates in the dom. Anyways, I think there's a lot of clever stuff in here, but then again I wrote it. Happy to answer any questions and hope this is interesting/helpful to someone else out there. https://ift.tt/XcqeQit February 14, 2025 at 11:38PM

Show HN: Dev SSO IdP, a mock single sign-on provider as a development aide https://ift.tt/PzAKiyD

Show HN: Dev SSO IdP, a mock single sign-on provider as a development aide Hi HN! This project grew out of my want for the development of my web UIs to not get hung up on integration with OpenID Connect single sign-on. SSO was only available in our stage and prod environments. Getting this integration laid down and tested fast, without having to jury-rig something in stage, would've been huge. And so I decided to build a solution myself. Hence, Dev SSO IdP. The vision for it is to mock all the features of an OIDC SSO server that would be pertinent to the development of web apps. To try it out: 1) Create a file called `.production.env` and paste in it the following 2 lines to start with: DEVSSOIDP_PERCENT_ENCODED_REDIRECT_URIS=http%3A%2F%2Flocalhost%3A5173 DEVSSOIDP_CLIENT_IDS=my_cool_app 2a) (with Node) Clone the repo with `git clone https://ift.tt/Qj4LtU9 `, then overwrite the project's `.production.env` with yours, then in the project's folder run `npm install`, then `npm start` 2b) (with Docker) Run `docker run -p 3000:3000 --rm --env-file .production.env bmcase/devssoidp:1.0.0` You can then see it at (and have your app redirect to) http://localhost:3000/authorize?response_type=code&client_id... You can add or change environment variables in `.production.env` in the likely case that its defaults don't apply to you. The GitHub readme goes into more detail on all of this. They say "be flexible in what you accept and strict in what you output". But Dev SSO IdP is intentionally strict in what it accepts so that I could catch issues faster. It raises an alarm in dev so you don't later get one in prod. This version I am comfortable designating v1.0.0. It has all the features needed for the OIDC code flow. I'd appreciate any advice, and in particular am interested in: * Would this actually be useful in your projects? Is there anything else it would need? * Do you use the OIDC implicit flow? I've never had reason to, and I understand it's regarded as a bad practice. But I worry I may be in a bubble and so I want to know if there's in fact a lot of folks out there who use the implicit flow. Aside, I'm open to work, and would be interested in bringing my full stack skills to your team (or the team of someone you want to do a favor for), in the Austin TX area or remotely. I'm happy to hear from you by email (ben@benswords.com) or LinkedIn ( https://ift.tt/EKjq7lY ). https://ift.tt/tX8TGSM February 14, 2025 at 01:53AM

Show HN: A no-build fullstack SSR TypeScript web framework https://ift.tt/zLumJBA

Show HN: A no-build fullstack SSR TypeScript web framework Hi HN family! I'd love to seek your insights on a fullstack web framework that employs a different approach: no build. It's not a new concept. The folks as Preact mentioned it: https://ift.tt/aztdijP However, in the Web Framework market, I've yet to find many that support both "no build" and "SSR". There's always some sorts of "client mount" and "server mount" and either has (or both have) to go through a build (bundling) process. With the build process, there comes additional maintenance efforts and cognitive load. I've enjoyed wrestling with tsconfig, webpack config, all sorts of presets and plugins countless times... When things work, they just work, but when we need sth a bit custom or unconventional, then we're almost always in for a tough ride. (or it's just me ) Not to say I'm against any existing build workflow. In fact I benefited a lot in the past from webpack, and i'm very positive about modern bundlers like Parcel 2, Turbopack, rspack, etc. I just feel it'd be fair to save some slots for the "no build" route :) To this end, I spent the last month working on a prototype of a TypeScript fullstack SSR web framework. It's compatible with Deno and Bun runtimes. I'd love to make it compatible with Node.js as well (at some point). The framework registry page ( https://ift.tt/ge0xmyp ) summarizes the motives expressed so far. An example deployment is available at: https://ift.tt/Kwh9dVN The code behind the deployment above: https://ift.tt/c903OtX PS: you may see Preact being used & mentioned everywhere but I'm positive that React is 100% supported as well (just drop-in & use). I just happened to choose Preact to experience it more for myself. I look forward to your thoughts :) and learning if this might (or might not) be a feasible idea at scale. And perhaps, which future directions you would see this (or something like it) goes. Thank you much for any insight! https://ift.tt/ge0xmyp February 13, 2025 at 01:24AM

Show HN: Sort lines semantically using llm-sort This is a small plugin I made for Simon Willison's llm utility. You can do things like: cat names.txt | llm sort -q "Which one of these names is best for a pet seagull?" cat books.txt | llm sort -q "Which book is more related to basic vs. advanced CS topics?" I see a lot of potential marrying LLMs with classic UNIX interfaces. https://ift.tt/cmjHiLu February 11, 2025 at 08:55AM
