• Lightning Fast — Built with Go and typescript-go, 20-40x faster than ESLint
• Minimal Configuration — Typed linting enabled by default, minimal setup required
• ESLint Compatible — Compatible with most ESLint and TypeScript-ESLint configurations
• TypeScript First — Uses TypeScript Compiler semantics as the single source of truth
• Project-Level Analysis — Cross-module analysis by default, more powerful than file-level linting
• Monorepo Ready — First-class support for large-scale monorepos with TypeScript project references
• Batteries Included — Ships with all TypeScript-ESLint rules and widely-used ESLint rules out of the box
• Extensible — Exposes AST, type information, and global checker data for custom rules

Notes

• rslint is currently in an experimental phase but under active development by the web-infra-dev team (ByteDance)
• It is a fork of tsgolint, building upon the innovative proof-of-concept work by @auvred
• rslint performs cross-module analysis by default, enabling more powerful semantic analysis
• Use --help to see all available commands and flags
