    We're excited to announce Lowdefy V4, a full-stack web framework built on top of Next.js that simplifies building web applications, internal tools, admin panels, BI dashboards, and CRUD apps using YAML or JSON configuration files. New in V4: Next.js: Lowdefy now runs on top of the Next.js framework. All of Auth.js: App auth is now handled by Auth.js supported providers, adapters and callbacks and events, easy to configure, but all of which can be customized. Plugin extensibility: Apps can now be extended with any npm or pnpm workspace plugins. Our story: We have developed a simple…

    Hey HN! I built Typebase, a library that gives you Convex's DX with Supabase's openness. After trying Supabase I liked how fast it is to spin up a DB and auth, but really didn't like using RLS and SQL for authorization. With Convex I loved how your server "lives" in your code, but disliked the DB model and the realtime-first defaults. With Typebase you just write TS files inside a typebase/ folder in your existing repo. You can define your DB tables inside a schema.ts file and export server functions that your frontend calls like local functions, fully typed. Auth is built in. Then one…

    Hi Hacker News! My name is Sagar, I’m working on a startup called Speakeasy - we’re making all APIs self-service. The platform is currently in beta, but we’re independently launching this tool which you can use to generate language-idiomatic, statically-typed TS SDKs from any public OpenAPI schemas. We hope to continue iterating on this to give devs a way to easily generate high fidelity client SDKs for all the major languages. Inspiration for this product is from past experiences struggling with OpenAPI. I was originally optimistic about using the OpenAPI tools to build out our offering,…

    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…

    Hi HN! 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://preactjs.com/guide/v10/no-build-workflows/ 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…

    Hey there HN! I just wrapped up an all-day documentation spree for Instant API, a JavaScript framework for easily building web APIs that implements type safety at the HTTP interface. It uses a function-as-a-service approach combined with a slightly modified JSDoc spec to automatically enforce parameter and schema validation before HTTP requests make it through to your code. You just write comments above your endpoint functions and voila, enforced type safety contracts between your API endpoints and your developers. OpenAPI specifications are generated automatically as a byproduct of simply…

    About a year ago, I stumbled upon a new Nodejs language called "Imba", I found this language to be interesting and it seemed like it had a lot of potential. Doing a bit of digging, I realized no one had created a framework for it, so what did a normal dev do? Well, a normal dev went ahead and created another Nodejs Framework, only this time it was meant for Imba. So what did I create? I created a batteries included Framework heavily inspired by Laravel but it runs on Nodejs, and uses Imba as the default language, but you can actually use TypeScript or JavaScript. In fact, when creating a new…

    Hi HN, I built Titan, a backend framework where you write routes and logic in JavaScript, and the CLI compiles everything into a single Rust + Axum binary using the Boa JS engine. No Node.js is required in production. The idea is to keep JS developer experience while getting Rust performance and a self-contained deployable server. Current features: JS route DSL Action system mapped to Rust esbuild bundling Generated Rust server with Axum Hot-reload dev server Single-binary output Repo: https://github.com/ezet-galaxy/-ezetgalaxy-titan Would love feedback on the…
