6 days ago - SWC (stands for Speedy Web Compiler) is a super-fast TypeScript / JavaScript compiler written in Rust. It's a library for Rust and JavaScript at the same time.

May 15, 2020 - There is logic in Rust to deal with identification of "type substitutions" for TypeScript files. For example if you are loading a JavaScript file, but you want to use type definitions for the compiler to type check against instead of the JavaScript file, Deno supports using things like X-TypeScript-Types header to identify those files.

SWC is an extensible Rust-based platform for the next generation of fast developer tools. It’s used by tools like Next.js, Parcel, and Deno, as well as companies like Vercel, ByteDance, Tencent, Shopify, Trip.com, and more. SWC can be used for both compilation and bundling. For compilation, it takes JavaScript / TypeScript files using modern JavaScript features and outputs valid code that is supported by all major browsers.

June 24, 2020 - SWC is a compiler for typescript and javascript written in rust and is being developed by a 22 year old South Korean student.

June 4, 2024 - Rust and TypeScript are both statically typed languages. This means the compiler tries to infer the data type during compilation.

February 14, 2023 - Rust has so many similiarities to JavaScript/TypeScript that it's quick and easy to get the core concepts down. Start learning Rust today, and develop a foundation for creating web services and more.

November 24, 2020 - The latter is a JavaScript/TypeScript compiler and bundler written in Rust. Swc claims to be 20 times faster than the Babel compiler on a single thread — and 70 times faster on one four-core benchmark.

May 13, 2018 - TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. ... Chat about javascript and javascript related projects. Yes, typescript counts. Please keep self promotion to a minimum/reasonable level.

April 26, 2020 - The analogy that comes to mind is that Rust is a really nice sports car with a great engine. It handles like a dream and you can feel the powerful engine humming while driving it. With the right open road, it's a great time. You can really optimize code, make great abstractions and work with ...

March 26, 2025 - After the TypeScript team announced their transition to Go, all my social channels were filled with either complaints about “Why not Rust” or the victorious “Go is beating Rust.”

May 29, 2023 - Donny (kdy1 on GitHub) is rewriting TypeScript in Rust hoping to speed up tsc which is slow due to its TypeScript base.

December 4, 2024 - Rust allows you to be more expressive in the syntax, and depending on the background, this may be more than the developer is used to thinking about, so in comparison, Typescript will be a “lighter” syntactic load. As mentioned above, Rust's compiler is strict; it uses the borrow checker to enforce memory allocation rules, which prevents data races, use-after-free errors and memory corruption errors, all common causes of security vulnerabilities.

September 28, 2025 - A high-performance compiler that transforms TypeScript code into idiomatic Rust, supporting all TypeScript features including advanced types, generics, decorators, and async/await patterns.

March 11, 2025 - The guy who wrote SWC did try to write a TSC in Rust, and then abandoned it. TypeScript is an engineering monster if you know TypeScript good enough, as is any complex-typed (to some extent) compiler, and rewriting such a compiler in Rust is a whole lot of effort.

1 week ago - The Oxidation Compiler is a collection of high-performance tools for JavaScript and TypeScript written in Rust.

December 17, 2022 - But then I find some third party code which seems to use the kitchen sink approach to typing, AKA the "look at how smart we are" approach, and it's a nightmare to understand. A type system is supposed to make code easier to work with, by the time you're spending more time understanding the ...

March 20, 2025 - “Do a complete from-scratch rewrite in Rust, which could take years and yield an incompatible version of TypeScript that no one could actually use…” · “Just do a port in Go and get something usable in a year or so and have something that’s extremely compatible in terms of semantics and extremely competitive in terms of performance.” · In a comment on Hacker News, Cavanaugh reminded readers that in 2022 the SWC (Speedy Web Compiler) project also chose Go for a port of the TypeScript type checker tsc.

May 15, 2020 - This is a massive undertaking. TSC is a moving target. I occasionally contribute to it. It’s a fairly complex project. Even the checker + binder (which is the core of TS) is pretty complex · One idea that comes to mind is to work with Typescript team that they are only using a subset of ...
