I built a package that provides a feature-flag service powered entirely by GitHub issues and NextJS. Define a list of app features and environments in an issue description, then simply toggle a feature on/off by ticking a checkbox - without having to redeploy your app. It can be used directly inside a NextJS app or be deployed as a standalone service and consumed by any client over HTTP. Plus it supports react server-side components right out of the box. The architecture leverages GitHub Webhooks to invalidate the NextJS cache whenever there is a change. The next time a user reloads a…

Hi. We just open sourced Bullet Train, a Feature Flag and Remote Config platform. It's a collection of tools: server API, admin front end and clients for a bunch of different platforms. Together they allow you to control feature flags and remote config across projects, environments and users. We realised that we were building ad-hoc feature flag stuff into individual projects over and over, so we had a look around to see if there was a way of doing this in a more formal manner. There are a few commercial solutions around but they were quite expensive and seemed to be aimed more at the…

Hey everyone! I've been working on something called Afterburner: a fast, embeddable JS/TS runtime written in Rust, with a capability sandbox baked right in. Scripts run locked down by default: no network, no filesystem, no environment variables. You explicitly grant whatever access a script actually needs, and every call gets hard caps on CPU, memory, and time. The goal isn't to replace your existing stack. It's to fit cleanly into it: Embed a JS/TS engine in your Rust app with a single crate. Run user scripts, plugins, business rules, or edge logic, each call fully sandboxed. Wrap…

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.

Hello I'm Jack, I was previously a Site Reliability Engineer and i've been working on monitro.dev which makes log monitoring simple for individuals or small teams. It allows you to easily forward any logs to multiple channels such as Slack, Discord & Telegram. The events are also viewable though the admin dashboard and are easily filterable. Currently there is only an NPM package with javascript / typescript support but i have plans to expand this to other languages such as Python, Rust etc. The package has many options, one of them is forwarding any uncaught exception and as an event…

I first shared Caravan on HN in 2024[0]. At the time, I had built the initial version over the Christmas holidays. You guys seemed to enjoy it. Today, I’ve released another major update after spending the last couple of weeks working on it. [0]: https://news.ycombinator.com/item?id=42508130

Hi HN! RΞASON is an OSS Typescript framework for developing LLM apps that uses Typescript's interfaces to get structured output from an LLM. While there are other TS LLM frameworks, I think RΞASON fills a unique space in the market: it's laser-focused on only three areas and, most importantly, actively stays away from pre-made prompting & retrieval. I've been in the LLM space since GPT-3 originally came out, and I've always had problems with other frameworks, such as LangChain. I dislike that they focus a ton on out-of-the-box prompting & pre-made agents — I, as the dev, should be the one in…

I built a library that lets you find code patterns using familiar CSS-like selectors, then connected it to Claude via MCP so AI assistants can understand and refactor codebases. The Approach // Find code patterns with intuitive selectors: const asyncFunctions = tree.findAll('function[async]'); const todoComments = tree.findAll('comment[text="TODO"]'); const reactHooks = tree.hooks(); // Built-in React support // Chain smart transformations: tree.transform() .rename('oldFunction', 'newFunction') .removeUnusedImports() .toString(); Key Features - CSS-like…

This has been in use on our production systems for around two years now at Switchboard (https://switchboard.app). The problem we had was that we were using two different logging libs for our frontend and backend at the time (specifically roarr, and bunyan), and the API for the logging libs were not compatible with each other. Loglayer was designed to wrap around popular JS logging libraries where you can swap out any underlying library without re-writing your log entries to adapt to the new library. One common example is using plain "console" as a starting integration, but later…
