24 alternatives to es6_maps, new Elixir syntax feature via runtime compiler hacking
Hi HN! I thought you might enjoy this even if you don't know much about Elixir. `es6_maps` is a small library that introduces a "shorthand" map creation syntax, similar to shorthand object construction in JavaScript/TypeScript. For those unfamiliar with Elixir, the most interesting aspect might be how it achieves this. `es6_maps` takes advantage of BEAM (Erlang's VM) hot-reload capabilities to amend the Elixir compiler bytecode at runtime, adding functions that expand the shorthand syntax for further compilation. I think it's a nice showcase of the power you can wield (with care) when…

I'm Robbert, the creator of DataGridXL.js. Last month I released version 2 which includes many new features. DataGridXL is a free (and commercial) editable data table library written in ES6. My goal is to develop the most performant & user-friendly spreadsheet-like data table out there: - It has zero dependencies. You don’t need any framework to use DataGridXL. - It is lightweight (~250kb) and easy to use. It does not even require messing with CSS. - It has its own Virtual DOM implementation to prevent DOM errors. - Developer friendly. Supports all modern web browsers Please take a look at…

QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM. If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code. QuickBEAM runs that JavaScript inside OTP supervision trees. Each runtime is a process with a `Beam` global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system state It also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.). This makes it usable for: - SSR…

Hello, folks. I'm Jiang, the author of ESInfer. I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system. To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript. It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes. It is still in the very early stage, which offers…

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 applications like electron or tauri. It has rich ESM and typescript support. It has good DX and cli UX. I made it bc i didn't like using pkg or nexe, they cause a lot of problems with esm. LIMITATIONS: Now it has problems compiling projects with depencides containing binaries (e.g.…

Hey HN! Esolang Park is an online visual debugger interface for esoteric programming languages, that I've been working on for the past few months. For every supported language, Esolang Park provides the powerful Monaco code editor, syntax checking, debugging functionality and a visualisation of the runtime state. The core is language-agnostic - a "language provider" only needs to implement the esolang's parser, interpreter and visualisation UI (and some other little stuff). Apart from trying to boost DX for esolangs, the idea is for this to grow into a platform where people can discover and…

Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…
