Hello! This is Jeane and Samuel and we’re building RecipeUI. RecipeUI is an open source Postman alternative that uses TypeScript to statically type and autocomplete requests. We built this because current API tools don’t deal with the fact that some APIs are just painful to work with. For us, it’s usually error after error as we try to figure out how to properly form the first request. We recorded a demo to show you how TypeScript helps us autocomplete a request correctly. https://youtu.be/O_Mly_p-g5s How does our platform improve the developer experience? The analogy is…

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…

Hi HN - Peter from DBOS here with my co-founder Qian (qianl_cs) Today we want to share our TypeScript library for lightweight durable execution. We’ve been working on it since last year and recently released v2.0 with a ton of new features and major API overhaul. https://github.com/dbos-inc/dbos-transact-ts Durable execution means persisting the execution state of your program while it runs, so if it is ever interrupted or crashes, it automatically resumes from where it left off. Durable execution is useful for a lot of things: - Orchestrating long-running or…

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…

Wrote a thing about what makes Elysia stand out in a performance benchmark game Basically, there's a JIT "compiler" embedded into a framework This approach has been used by ajv and TypeBox before for input validation, making it faster than other competitors Elysia basically does the same, but scales that into a full backend framework This gave Elysia an unfair advantage in the performance game, making Elysia the fastest framework on Bun runtime, but also faster than most on Node, Deno, and Cloudflare Worker as well, when using the same underlying HTTP adapter There is an escape hatch if…

Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers. This is something I've built to make implementing Go-style "control loops" feasible in JavaScript, but there are many possible applications. Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol"…

I built Morph, an experimental fullstack HTML-first library for Deno, Node, and Bun. Everything returns HTML, not JSON. No React, no Vite — just plain HTML with server-side rendering. No build steps, no preprocessors, no complex configs — everything runs from a single file. Perfect for Telegram Web Apps, internal tools, simple admin panels, dashboards, or anywhere a full-blown SPA feels like overkill. Important: I built this entirely for myself — to solve my own problems. I hate complex frontend. I hate writing it. And I don’t want to waste time on it. But maybe it’ll help you too.

Spent a week in the break building a pre-compiler that brings type safety to runtime. Still pretty early, but generally does what it says. Looking for feedback, code that breaks it (check out the playground), ideas etc.

I wanted a safer alternative to RegExp for TypeScript that uses a linear-time engine, so I built Regolith. Why: Many CVEs happen because TypeScript libraries are vulnerable to Regular Expression Denial of Service attacks. I learned about this problem while doing undergraduate research and found that languages like Rust have built-in protection but languages like JavaScript, TypeScript, and Python do not. This library attempts to mitigate these vulnerabilities for TypeScript and JavaScript. How: Regolith uses Rust's Regex library under the hood to prevent ReDoS attacks. The Rust Regex library…

Next.js has APIs to read and update search params (the /?foo=bar part of the URL), but they lack type-safety for consistent keys and proper parsing/serializing of JS data types. I found myself repeatedly building the same custom hook to get a React.useState-like approach. In 2021, I published it to NPM and then forgot about it. Since then, the `nuqs` package has gained popularity and is now used by companies like Vercel, Auth.js, Gitbook, and Midday.ai, with 200K weekly downloads. It's been fun building this as a side project and automating as much as possible to ensure a…

I've built a type-safe semantic layer in code, for ClickHouse. If you're building analytics off ClickHouse in TypeScript, I would love your feedback. With hypequery there is no platform to adopt, no YAML sprawl. It runs where your app runs. Key features: - Define metrics once, reuse them everywhere: Declare dimensions and measures in one place and then pull from the same source of truth. - Compiles to ClickHouse SQL: No service, no proxy, no extra runtime to deploy. It's a library that generates SQL and runs where your app runs. - Multi-tenancy & Authentication ready: Cross-tenant queries…

Hi HN — I am the CTO of Rierino (https://rierino.com/platform/core), a low-code backend platform built for developers, not business users. We recently launched our Developer Lite version on AWS Marketplace, and we're offering a free private trial to HN users. We built our low-code platform while working with scale-ups, out of frustration with how painful and expensive backend logic can be to implement and maintain in high-speed, distributed environments. It either meant hand-coding everything or relying on rigid tools that abstract away too much. We tested a range of LCNC…
