Project is in early development with minimal setup documentation. Expect rough edges and incomplete TypeScript compatibility. Best suited for contributors and early adopters comfortable with Rust toolchains.

In plain English

This project is a TypeScript type checker written in Rust. TypeScript is a programming language that adds type annotations to JavaScript, and it comes with its own built-in type checker. The goal of stc is to build a faster replacement for that built-in checker by rewriting the core logic in Rust, a language known for producing very fast software. At the time of the README, the project was in an early stage and under active development. The README is brief and does not describe the current state of compatibility with TypeScript, how much of the type system is supported, or how to install and use the tool. It links to a contributing guide and lists financial sponsors, suggesting the project was seeking community support to continue development. The README does not provide enough detail to assess how complete or usable stc is for real projects.

Copy-paste prompts

Prompt 1

I want to use stc as a drop-in replacement for tsc to type-check my TypeScript project. What do I need to install and how do I run it?

Prompt 2

How compatible is stc with the official TypeScript type system? What features or edge cases are not yet supported?

Prompt 3

I want to contribute to stc. Walk me through the Rust codebase structure and explain where the core type-checking logic lives.

Prompt 4

Compare stc and tsc: what makes Rust a better fit for a TypeScript type checker, and what are the trade-offs?

Prompt 5

What is the current roadmap for stc reaching feature parity with the official TypeScript compiler?
