    Crust – A CLI framework for TypeScript and Bun▲95

    We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

    Stripe-quality API client libraries with a single button click▲27

    TL;DR- Libninja will generate world-class client libraries for you, without you needing to fiddle with openapi-generator, maintain build pipelines, and so forth. If you just want Rust, reach out, and I'll create your client library at no cost, because I want to help Rust's ecosystem grow. -- Hi HN, I got into Rust in a big way about 9 months ago. While the language is quickly maturing, one large gap in the ecosystem is immature or non-existent client libraries for common API services like Plaid, Stripe, Twilio, Github, Slack, and so on. The existing openapi-generator templates create Rust…

    Turn OpenAPI to Universal TypeScript SDKs▲27

    Hi HN! We’re excited to share our new code generator that lets you ship high-quality TypeScript SDKs, that your users will love, from your OpenAPI documents. Our ongoing goal is to help you build one SDK that runs anywhere modern JavaScript runs. This includes new runtimes like Deno and Bun in addition to the ever-popular Node.js. Additionally, the popularity of AI has meant server-sent events and file streaming are also commonplace - we wanted to cover these use cases too. This explosion in new runtimes and ways of interacting with APIs shifts cognitive burden on API developers often having…

    A tool to Convert JSON schemas into TypeScript Deno classes▲43

    Hello all To preface this is just something I've been making as a learning exercise, so all feedback is appreciated. This is a tool that converts JSON schemas into TypeScript utility classes for use in Deno. Automatic Type Generation: Typescript interfaces for the compressed and uncompressed versions of your data. Compression & Decompression: Compress and decompress your data. Validation: Built-in data validation using Ajv ensures your data adheres to the schema. Reusability: Once generated, the utility classes can be used in other Deno projects. It currently only supports a subset of JSON…

    Bebo – run Clojure scripts on Deno▲48

    Made this little thing: https://github.com/borkdude/bebo In the spirit of deno it allows you to install a script from an https location but for Clojure(Script, .cljs). Why would you use this? I love Clojure and I'd love to see it in more places than the JVM and browser. Maybe you do too. It is similar to the idea of nbb which allows you to run .cljs scripts on Node.js via the SCI interpreter: - https://github.com/babashka/nbb - https://github.com/babashka/sci I posted this project yesterday but forgot to add "Show HN"... I hope that…
