24 alternatives to Oxidase – Transpiles TypeScript at the Speed of Parsing
Hi HN, Oxidase is my experiment to build a TypeScript transpiler that works like ts-blank-space[0] and Node.js' built-in type stripping[1], but also supports enums and namespaces. I've tried some optimizations on it and am surprised to find that it's now as fast as oxc, the TypeScript parser it's based on. Check the link for the benchmark results and details on how I make this possible if you are interested. The name pays homage to oxc (same prefix) and sucrase[2] (name for another type of enzyme), where I borrowed the idea of no AST allocation optimization. [0]…

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

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.…

eno [1] - A modern plaintext language w/ libraries [2] for JavaScript, Python, Ruby & soon more! We migrated a big relational research database to a file-based solution - requirements were: - Super fast and easy editability for users - Highest performance for parsing/validating >10K documents on every user change. Our trials with YAML/TOML showed us that we wanted something both faster [3][4] and easier [4], something tailored for file-based content management ... and after months of research & development it's now publicly available (under MIT license) for everyone!

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…

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! While working on a project that involves frequently parsing a lot of feeds, I needed a fast JavaScript-based parser to extract specific fields from feed namespaces. Existing Node packages were either too slow or merged all feed formats, losing namespace information. So I decided to write it myself and created this NPM package with a simple API. Feedsmith supports all feed formats and many popular namespaces, including: Podcast, Media, iTunes, Dublin Core, and more. It can also parse and generate OPML files. I am currently adding support for more namespaces and feed generation for RSS,…

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 the author of SharpTS, a TypeScript interpreter and ahead-of-time compiler written in C#. *What makes it different:* - Dual execution modes - interpret TypeScript directly OR compile to native .NET executables - Full C# interop - compile TypeScript to DLLs that C# projects can reference with full type safety *What works today:* - Core TypeScript: classes, interfaces, generics, async/await, decorators - Advanced types: union/intersection types, literal types, type guards - Compiles to verifiable .NET IL with performance comparable to hand-written C# - 80+ unit tests,…

I built a cli tool that gets you started with TypeScript development with zero config. Initially created to solve my own problem but thought it might be useful for others as well. - SWC compiler - TypeScript type check support - Live reload support - .env file support - Path alias support - Typescript script runner - REPL support Please tell me I am not going down a rabbit hole.

Hello all To preface this is just something I've been making as a learning exercise, so all feedback is appreciated. This is a tool that converts JSON schemas into TypeScript utility classes for use in Deno. Automatic Type Generation: Typescript interfaces for the compressed and uncompressed versions of your data. Compression & Decompression: Compress and decompress your data. Validation: Built-in data validation using Ajv ensures your data adheres to the schema. Reusability: Once generated, the utility classes can be used in other Deno projects. It currently only supports a subset of JSON…
