Show HN: BookaBooka, a multilingual picture book app for children 2-8 https://bit.ly/3X4Pwjv

Show HN: BookaBooka, a multilingual picture book app for children 2-8 BookaBooka is a child friendly app with a library of 150+ picture books available in 20+ languages. Books can be read in single, or dual language mode. Any language combination is possible. Research shows: - clear benefits of children that are being read to from an early age. - parents should read to their children in the language they are most proficient in, which might be a different language from the one used in school, and therefore a language that is harder for them to acquire books in. With BookaBooka I hope to provide all children in the world, including immigrants, expats and refugees with a library in their native tongue, and the privilege of being read to, even if parents aren't willing or able. I work with a growing network of language enthusiasts that help me translate / narrate our collection. These people work on a semi-voluntary basis (royalty model + low revenue currently resembles volunteer work). You can try BookaBooka out for free, it is available in all major appstores: - iOS: https://apple.co/3lc0jLi... - Android: https://bit.ly/3DFCqCm... - Microsoft: https://bit.ly/3DHC0LT https://bit.ly/3jwfq1P February 4, 2023 at 02:19PM

Show HN: Mass Dissent – Easily send a letter to U.S. Congress representatives https://bit.ly/3jzt4Bh

Show HN: Mass Dissent – Easily send a letter to U.S. Congress representatives Hi HN! I just launched the MVP of Mass Dissent, a website that provides an easy way to send a short message as physical mail to your representatives in the U.S. Congress. The site reduces the effort required to send a letter to an elected official, hopefully resulting in more people writing to their representatives regarding the issues they care about. Originally, the idea was to allow users to select Tweets to print onto a postcard that would be sent to their representatives. However, last fall the Twitter OAuth API stopped working (for me at least), so I decided to pivot slightly to allowing users to compose a message directly on Mass Dissent. This has a side benefit of allowing users to write longer messages than what would be available using Tweets. Some notes on the technologies used: - The code is written in TypeScript[1], uses Next.js[2] and the MUI[3] React component library for the UI, and the backend APIs are created using tRPC[4]. - The site is hosted on Vercel[5] and it's using Supabase[6] for the DB. - The messages themselves are printed and mailed using Lob[7]. I also store the representatives' addresses in Lob so I don't need to maintain a separate DB table for this. - I'm able to get congress member data from the Congress.gov API[8] (though some post-processing is required because, for example, a few members are missing a headshot image). I created a little CLI tool using Rust[9] to fetch the data from Congress.gov, normalize it for usage by the site, and upload the addresses to Lob. The representatives data is pretty static so I just store it as a big JSON file on the server-side. - Payments are processed using Stripe[10] and payment notification emails are sent using Sendgrid[11]. - Previously, when the site was integrated with the Twitter OAuth API, it was also using NextAuth.js[12], but there currently isn't much need for auth so I removed it for now. At my day job I'm mainly a backend dev working with Java/AWS, so it's been a lot of fun playing with all these different technologies!

Show HN: I built open-source suite of tools to streamline Microservices https://bit.ly/3HU3W1k

Show HN: I built open-source suite of tools to streamline Microservices I have been dedicating my time and efforts to a project in the world of Node.js development. This project simplifies and streamlines the creation of microservice architecture, utilizing NestJS as its main backend framework. It is packed with a plethora of tools and features, including code generators for services and libraries, a user-friendly CLI for seamless local deployment, Terraform code generation to effortlessly set up the infrastructure on AWS, an NX monorepo solution that keeps all services organized in one place, a Github CI generator that streamlines the deployment process to AWS, and enforces event-driven design through the reliable RabbitMQ message broker. Additionally, strict folder structure is imposed to maintain a clean and well-organized monorepo. The entire project is open-sourced, accompanied by extensive documentation and a demo project to provide a hands-on experience. The purpose of this project is to empower developers by guiding them towards the right approach when building their applications and eliminating the fear of the perceived complexity associated with microservice architecture through the use of powerful code generators. https://bit.ly/3DF5SZj February 3, 2023 at 01:12PM

Show HN: Dev-Docs – A tool that helps you document as you code https://bit.ly/3JFRNyq

Show HN: Dev-Docs – A tool that helps you document as you code Hi all, Super excited to share that I am building Dev-Docs, and I wanted to create a post to get other developers' thoughts. Background: Developers know how important it is to document their codebases, but often, it's an afterthought that ends up taking a lot of time and effort. That's where Dev-Docs comes in - a solution that helps developers document as they code, making the process easier and more efficient. Features: Dev-Docs handles both internal documentation for teams and external documentation around APIs and codebases for customers and partners. Internal Documentation: Dev-Docs makes it easy for engineers to document their code, right within their editor. This way, they can easily document the code they're working on, without having to switch between multiple tools. Think of it as a mini local notion that lives within vs code. External API and Codebase Documentation: Developers can also use Dev-Docs to document their external APIs and codebases, making it easier for their customers and partners to understand how the code works. Quick demo(From December): https://youtu.be/fmcgw3MkW4E Currently it is live but I am going to try to refine it a bit during this month and hopefully market a more open launch. In the meantime I would love some feedback on the video/product(hopefully none that obliterates my identity and all of my self-esteem). :') Additionally feel free to dm on linkedin if you have direct feedback or want to start using the rough version of it: https://bit.ly/3HU7p0a .

Show HN: Using Google Sheets to manage localization strings across platforms https://bit.ly/3DsK56U

Show HN: Using Google Sheets to manage localization strings across platforms As an app developer, I noticed that smaller teams frequently run into the hassles of managing translation strings across iOS, Android and web, and keeping them in sync and up to date. To make this a little easier I've been working on a small utility that allows you to use Google Sheets to manage these translations. Perfect for small teams that do not need any of the advanced features that paid platforms offer, but still want to have an easy to use centralised place to edit these strings. Without creating any account or whatsoever, you can use the Localeasy endpoint to convert your sheet into translations files for multiple platforms: iOS/macOS, Android, Rails, JSON, or YAML. I would love to hear your feedback! https://bit.ly/3JANbcS February 1, 2023 at 01:41PM
