Astra – a new js2exe compiler

In plain words

Astra is a Node.js to executable compiler designed for building command-line tools and server applications. It uses esbuild and Node SEA with postject to bundle code into Windows binaries. The tool offers strong ESM and TypeScript support with an emphasis on developer experience. Unlike similar tools like pkg or nexe, Astra handles ESM modules more reliably. Currently, it has limitations with dependencies containing native binaries and only supports Windows compilation.

🚀 Fast, reliable and easy-to-use js-to-exe compiler. - astracompiler/cli

It's aiming to compile servers (express, fastify) or CLIs (commander) so it's not replacement of electron. For now it only compiles windows applications. (I'm working on macOS and linux) Different than the others - Astra is a new approach to compiling JavaScript/TypeScript applications. It uses a different method than other compilers like pkg or nexe. Compile newest versions of Node.js - Astra supports the latest Node.js versions. Fast build time - Powered by esbuild , Astra ensures the fastest possible compilation speed. Improved support for ECMAScript - Astra supports compiling ESM-based applications, with workarounds for limitations in Node.js SEA. Delightful DX - With signale , inquirer…from github.com

In the maker’s words, at launch

Hi everyone I'm new here and i wanted to introduce my project i've been working on. Astra is a simple but powerful node.js to exe compiler. It uses esbuild and Node SEA. It uses postject to inject your code to nodejs binary. It focuses more on compiling cli and Servers like pkg or nexe (express) than fullstack…

  I made a CLI tool to create web extensions with no build configuration2024 · github.com · ▲381

  Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

  Nub – A Bun-like all-in-one toolkit for Node.jsJun 2026 · github.com · ▲277

  Colin here, creator of Nub. I’ve had the general shape of this in mind for years. Nub runs your code with stock `node`, augmented with a `--require` preload hook[0] that adds a transpiler (oxc-powered, packaged as a Node-API add-on), registers a module resolution hook[1], and injects polyfills as needed for APIs like `Worker`, `Temporal`, etc. All purely additive, your code ultimately runs using Node’s actual engine & stdlib implementations.

  Asdf Clone Written in Rust2023 · ▲79

  I think that asdf (https://asdf-vm.com) was a great idea for a project. It helps consolidate installing and running different programming languages into a similar UX. It also is built with a plugin interface that makes it easy to build support for new languages. However it is so slow. I was just testing `node -v` and it was taking ~900ms. That kind of overhead is completely unusable. My shell prompt uses runtimes inside of it for various things so this effectively makes every command take multiple seconds to complete. So I rebuilt it in Rust but using the same plugin ecosystem so…

  Ad Astra – scripting language platform for Rust2024 · github.com · ▲6

  Ad Astra is a dynamically typed scripting language designed for embedded use in Rust programs. It belongs to the same category as languages like Rhai and Rune, where developers expose APIs implemented in Rust to a dynamic, domain-specific scripting environment, enabling a rapid edit-compile-run cycle. Informally, you might think of Ad Astra as a "Lua" for Rust. Such systems have many applications, including the development of plugin platforms based on scripts for video game engines. Ad Astra primarily focuses on ergonomics, both for the scripting platform developer and the script user: 1.…

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
