Show HN: Shadcn/pro – Advanced Next 15 and React 19 SaaS starter kit https://ift.tt/BD2GFph

Show HN: Shadcn/pro – Advanced Next 15 and React 19 SaaS starter kit Hey HN, Hope you are doing well! As a fellow founder, I've got something that could save you 2-5 months of development time. I'm excited to share shadcn/pro, a SaaS starter kit for building modern web apps. It’s built with Next.js 15, React 19, Auth.js (next-auth v5) and shadcn/ui. The primary focus is on the core aspects of the web application, including authentication, billing, onboarding, organization management, member invites, profile management, email integration, dashboards, master/detail pages, API keys, webhooks and more. As you probably noticed Next/React/Auth.js is currently stuck in an upgrade limbo. There are major changes in Next 15 regarding caching and new action hooks in React 19. Furthermore Auth.js got rewritten to fit the app router model. What if you could use the latest versions, but make it some else's problem (me). I'm committed to keeping all dependencies up-to-date and adding features you need but don't have time to build while you can focus on your product domain. The application is well-designed, fully responsive and built using server actions and React Server Components (RSC). Some of the libraries used are - next-safe-action - nuqs - nice-modal-react - react-email - dnd kit - zod As for the auth you get - A FULL implementation of the credentials provider including everything necessary from OTP to password resets. - Google and Microsoft logins - Connected accounts - Session management The license is very business-friendly. Unlimited developers, projects, and commercial use. No strings attached. Website: https://shadcnpro.com/ Demo: https://ift.tt/7hrTyX3 What's your biggest pain point in SaaS development right now? Tell me what you think! https://shadcnpro.com/ August 14, 2024 at 11:36PM

Show HN: My Care Voice – We Help You Prepare for the What Ifs https://ift.tt/JWn9tKe

Show HN: My Care Voice – We Help You Prepare for the What Ifs We are excited to introduce My Care Voice to the HN community! It's been a personal quest of mine to develop a process to ease the burden of creating advance directives. Everyone needs them, but few think about it until it's too late. Typically, it requires an expensive visit to an attorney or the cumbersome, impersonal process of filling out paperwork. In 2016, my sister had a sudden heart attack in the middle of the afternoon. She was rushed to the hospital with no way to speak or respond. That was when I fully grasped the importance of having these wishes recorded and available. Her family, including her two kids in their early twenties, were in the hospital waiting room, not knowing her wishes during those terrifying moments. The doctors were completely in the dark about how far to go with life-sustaining measures. My Care Voice is the simplest way to create these invaluable advance directives, so your loved ones and caregivers won't have to guess your wishes if something unexpected happens. With My Care Voice, you can: Be informed with definitions and examples in an easy-to-follow journey that you can complete in minutes or over time. Receive reminders and status updates. Complete one or more of your advance directives at your own pace. Securely share your completed documents with care professionals and loved ones. Make updates or amend at any time as your life changes. Try My Care Voice now, and don't hesitate to share your feedback to help us build the ultimate advance directive experience! https://ift.tt/Yldxk3r August 15, 2024 at 02:34AM

Show HN: SlateDB – An embedded storage engine built on object storage https://ift.tt/RjptkX4

Show HN: SlateDB – An embedded storage engine built on object storage SlateDB is an embedded storage engine built as a log-structured merge-tree. Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage (S3, GCS, ABS, MinIO, Tigris, and so on). Leveraging object storage allows SlateDB to provide bottomless storage capacity, high durability, and easy replication. The trade-off is that object storage has a higher latency and higher API cost than local disk. To mitigate high write API costs (PUTs), SlateDB batches writes. Rather than writing every put() call to object storage, MemTables are flushed periodically to object storage as a string-sorted table (SST). The flush interval is configurable. To mitigate write latency, SlateDB provides an async put method. Clients that prefer strong durability can await on put until the MemTable is flushed to object storage (trading latency for durability). Clients that prefer lower latency can simply ignore the future returned by put. To mitigate read latency and read API costs (GETs), SlateDB will use standard LSM-tree caching techniques: in-memory block caches, compression, bloom filters, and local SST disk caches. https://ift.tt/kGOD3hR August 15, 2024 at 12:47AM

Show HN: I've open sourced DD Poker https://ift.tt/FR2LzN4

Show HN: I've open sourced DD Poker I'm the original author of DD Poker, a Java-based computer game that ran on Mac, Linux and Windows and originally sold in stores in physical boxes. I shut down the backend servers in 2017 but the game is still functional and people can still play each other online even though the central lobby and find-a-game functionality no longer work. I've been asked over the years to release the source code, especially during the pandemic, and again this year. I finally got motivated to clean up the code and put it out there. The code is 20 years old and uses some ancient Spring, log4j, Wicket and other dependencies, but it still works on Java 1.8. https://ift.tt/e1znqip August 14, 2024 at 04:04AM

Show HN: I built a tool to try artworks on your own wall https://ift.tt/Lm1pjr6

Show HN: I built a tool to try artworks on your own wall Simply upload a photo of your wall, upload the artwork images, position them, and download the result. It's very lightweight and nothing is uploaded to a server - everything runs directly in your browser. Why I made this: Existing apps (like Artrooms) fell short for me because they only offered stock wall images and limited 3D positioning, especially if your wall isn't perfectly frontal. I wanted something more flexible that would allow me to experiment with more scenarios, even when the photo is taken at a weird angle. The objective is to get a feel of how'd it look like, without the result being super realistic. Details: - Built with Three.js. - It's a static site hosted on Cloudflare. - Uploaded images are stored in IndexedDB. - Some effects, like shadows and blending, work intermittently. Sometimes they really work, and sometimes they fail horribly. - I've included a few galleries from classic artists and default wall images so you can test it out right away. - I tried to make the UI as intuitive as possible, but that was surprisingly hard - especially in mobile where the space is limited. Any feedback would be greatly appreciated :-) https://ift.tt/9CstZ0Y August 14, 2024 at 02:17AM

Show HN: AI Bartender in a Virtual Bar Note: The avatar will talk to you, so make sure you check your volume! Hello HN! I've seen a bunch of AI character type stuff online, but all of them were boring chat interfaces. I thought it would be more fun to give the characters an avatar and a 3d environment to interact with. The stack I'm using is Claude 3.5 for the LLM, OpenAI TTS, Stable Diffusion for generating drinks, and three.js for rendering. I exposed the prompt I'm using so people can play around with it by clicking the robot icon. If people find it interesting, I might add more environments, character customization options, etc. Hope you enjoy and let me know your thoughts/questions in the comments!

Show HN: Wannabe – A versatile Go tool for generating mock HTTP APIs https://ift.tt/FqgkSfE

Show HN: Wannabe – A versatile Go tool for generating mock HTTP APIs Hey HN! Half a year ago, I decided to learn the basics of Go and create something useful along the way. Thus, I created Wannabe, a tool that's useful for generating mock HTTP APIs used in integration and all the other kinds of testing. How it works? Wannabe functions as a standalone server. Upon receiving a request, it generates a cURL command from it based on the request matching configuration you set and generates a hash from the prepared cURL command. When in "proxy" or "mixed" mode, Wannabe proxies the request to the external provider and stores the request/response pair as a record in the configured storage provider using the generated hash as a key. When in "mixed" or "server" mode, Wannabe looks up the matching record in the configured storage provider using the generated hash as a record key and responds with the stored response if it finds a matching record. Of course, similar tools already exist, but this is the one I started, and I'm already implementing it into testing flows at the company I work for. ;) I'm kindly inviting you to check out the repository and documentation on GitHub. All comments and potential contributions in the future are highly welcome. If there’s enough interest, I’m more than ready to develop it further. Take care... and keep creating! https://ift.tt/y0elEPT August 12, 2024 at 12:38AM

Show HN: Index and search *all* your documents https://ift.tt/kj3IAFy

Show HN: Index and search *all* your documents Hey HN! I've build a simple tool to index and search your documents. This uses two great open source libraries: apache tika (for extracting content from docs) and apache lucene (for searching). It's been built with kotlin ktor as a web framework. You can index all kind of files (i.e doc, docx, xls, ppt, pdf, txt, html even ORC pdfs) and then search them using very advanced queries like "always contain X", "never contain X", "X near Y", wildcard search, proper stemming support etc. We're using it on my work where we have hundreds of thousands of doc/docx/pdf files and it works flawlessly! https://ift.tt/a3nqr1d August 11, 2024 at 03:44PM

Show HN: Rust GUI Library via Flutter https://ift.tt/iYGoJFL

Show HN: Rust GUI Library via Flutter Hi, I made a bridge ( https://ift.tt/968BbR2 v2.0.0) between Flutter and Rust, which auto translates syntaxes like arbitrary types, &mut, async, traits, results, closure (callback), lifetimes, etc. The goal is to make a bridge between the two, seamlessly as if working in one single language. Then, as an example, I showed how to write Rust applications with GUI by utilizing Flutter. That is discussed in the link in details. To play with it, please visit the GitHub repo, or refer to the end of the article for detailed folders and commands. When I first released 1.0.0 years ago, it only contained few features compared to today. It is the result of the hard work of contributors and me, and many thanks to all the contributors! https://ift.tt/UubqynM August 11, 2024 at 08:25AM

Show HN: Made an anonymous feedback app TeamSays https://ift.tt/BVjeazU

Show HN: Made an anonymous feedback app TeamSays Hi HN, it’s Kaz. I’m a dev/solo founder here with my startup TeamSays [0], which is an anonymous feedback channel for improving workplace experience. Put simply, it’s like a founder/HR manager’s always-on sidekick. The product idea grew out of personal experience in startups and ~600 employee org, and me learning the shocking stats of the costs for replacing talent. To those of you who have a job: replacing you would cost your employer ~20% of your annual salary [1]. If you’re highly specialized (which is very likely) it can cost up to 4x your annual salary [2]. So, keep that in mind when you negotiate your compensation or work-life balance. Here’s how TeamSays works: 1. Once you create an account you get a link to a minimal chat-like UI, you only have to create categories and questions. 2. Then you share link with your team announcing a new channel for tracking feedback/issues. 2. Team members visit and share something, you can then see their conversations get analyzed, and turned into a positive or negative report that becomes visible in the dashboard. 3. That’s it. Nothing else to do other than update or remove questions/categories over time — minimal maintenance. 4. Get weekly/monthly reports on the state of positive/negative reports and take action. Over time you can track progress of issues as active questions get rotated, so on a long-term timeframe you can derive progress stats and see where things went right/wrong. Essentially, it’s a channel for your team members to express their true concerns and opinions (possibly in explicit manner that otherwise wouldn’t be possible), which simplifies work of HR department if you have one or becomes one if you don’t. Personal conflicts, stress/anxiety, or simply not feeling safe/confident enough are possible reasons to have this channel. The chat is fully anonymous and it does not provide any way to identify participants other than a simple browser-based ID. I’ve personally experienced bad managers in otherwise good enough organizations. As a remote team member building personal connection for transparency is hard. We all know the old saying “people quit managers, not companies” which might not be 100% true [3] but I do find it to be true enough to base TeamSays around it. Obviously, TeamSays is not for every team/organization out there but for those that value transparency and simply want to make sure they have a safe, and private channel that is remote-friendly for their colleagues, clients, or employees I believe it’s a good tool in the arsenal and I hope you consider giving it a go. Improving team experience, and providing space where everyone can truly share their concerns and keep their privacy/anonymity. Even a simple fact of sharing issues could be beneficial if there is no alternative at all. Here are some stats: 1/3 of modern day workers wouldn’t accept a job if they didn’t agree with the views of the leadership [4]; managers must use meaningful interactions to build engagement [5] as remote employees’ connection to their organization’s purpose is declining. Lots of metrics point to a high expectations of modern day workplace, and I’m here to offer help to HR process — there is a free 7-day trial, and setting it up should take only a few minutes. I made sure TeamSays supports numerous languages, and am doing my best to add more. Please share your thoughts. Thank you. [0]: https://teamsays.com [1]: https://ift.tt/DH8AvXq...
