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…

This past quarter has been awash with sophisticated npm supply chain attacks like [Shai-Hulud](https://www.cisa.gov/news-events/alerts/2025/09/23/widesprea...() and the [Chalk/debug Compromise](https://www.wiz.io/blog/widespread-npm-supply-chain-attack-b...). This CLI helps protect users from recently compromised packages by only downloading packages that have been public for a while (default is 90 days or older). Install: npm install -g @dendronhq/safe-npm Usage: safe-npm install react@^18 lodash How it works: - Queries…

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…

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.

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"…

You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. Made in Haskell!

As a developer of typia, have to alive in the new typescript-go era, I made a new toolchain for tsgo. Making the ttsc, I understood that the new plugin toolchain system can dramatically reduce lint rule checking time by integrating into the typescript-go. So made `@ttsc/lint`, and its time is 600x to 1600x faster than eslint. From now on, when you compile TypeScript, lint violations would be caught in the same time. No more need to run both `tsgo` and `eslint` independently. > This repository is not v1 yet because the typescript-go has not been released yet, but if you wanna experience…

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…

Hello, we're the Treenix team. We're building typed low-code runtime where humans and agents collaborate to build applications and workflows. Write a simple TypeScript class with methods, and Treenix automatically delivers admin interface, storage, API and MCP, access rules, UI form and audit trail. Views in Treenix are reactive, data-bound, and synced across all clients. They also support display contexts: data can render differently depending on the situation — a table in one place, a list in another. You can register multiple Views for the same data type, and the view engine picks the…

We've built a new type-stripping compiler for TypeScript source: `ts-blank-space` It's: * 5.6x faster than `tsc` due to zero-codegen * Written in TypeScript * Uses the official TypeScript parser * Accurate/preserved source locations * In used in production It uses the same novel approach that inspired Node 22.6.0's `--experimental-strip-types` functionality, released last month
