Rslint is a high‑performance linter for JavaScript and TypeScript written in Go that aims to replace ESLint/TypeScript‑ESLint with 20‑40× faster, typed‑first analysis. It provides out‑of‑the‑box compatibility with existing ESLint rules, cross‑module/type‑aware checking, and first‑class support for large monorepos, targeting developers who want fast, low‑config linting while staying in the TypeScript ecosystem.
