Why it matters

We look beyond stars: what problem it solves, whether it creates real utility, and what makes its approach worth noticing.

Last 90 days

Problem

A native Go implementation of the TypeScript compiler addressing performance bottlenecks of the JS/TS toolchain in large projects.

Practical value

Provides preview packages and editor extensions supporting core features like type checking and incremental builds, though the public API remains unready.

Innovation / differentiation

Porting the compiler core from JavaScript to Go explores the performance limits of language toolchains through a native rewrite.

Leverage potential

The project is planned to eventually merge back into the official Microsoft repository, currently serving as a standalone native port experiment.

Why now

The demand for TypeScript compilation performance optimization becomes critical as large monorepos and complex type systems continue to grow.

Community activity

In the last 90 days there were 248 new issues and 540 pull requests; the bounded issue/PR samples include 21 issue authors and 20 PR contributors, with 2 releases.

Maintainer responsiveness

The 98-issue window sample had a 100% close rate, and the 97-pull-request sample had a 69% merge rate. Maintainer-response observations covered 70% of that issue sample, with a 16% response rate and median first response of 1.2 days.

Key highlights

  • Compiler core rewritten in Go
  • Type checking and parsing compatible with TypeScript 6.0
  • Support for tsconfig.json and incremental builds

Quick start

How it is installed, how hard it is, and where to start.

Where it runs

Runs locally

Difficulty

Medium — some setup needed

Runs locally
  1. 01Install the preview package via npm.
  2. 02Use the npx tsgo command as a replacement for tsc to compile your project.
  3. 03To use it in VS Code, add "js/ts.experimental.useTsgo": true to your settings.

More about it

TypeScript-Go is a native Go implementation of the TypeScript compiler. By rewriting the compiler core, it aims to improve compilation and type-checking performance while maintaining high compatibility with the TypeScript 6.0 syntax and type system.

The project is currently in a preview state, with core features such as program creation, parsing, type checking, code generation, and incremental builds already implemented. It is intended to be merged into the official Microsoft TypeScript repository in the future.
