## What it is
RSLint is an extremely fast JavaScript and TypeScript linter written in Rust, distributed as a CLI binary and a Rust crate. It uses parallelism, a low-memory syntax tree, and an error-tolerant parser to lint code without requiring Node.js.

## Use cases
- lint javascript files without node
- fast parallel linting of a typescript codebase
- lint code with syntax errors using an error-tolerant parser
- replace eslint with a faster native binary linter
- embed a javascript linter in a rust application
- lint code in an editor on the fly as you type

## When to choose
- you need extremely fast, parallel linting of JS/TS without a Node runtime
- you want a linter that tolerates incomplete or broken syntax
- you want a Rust crate for parsing/linting JavaScript

## When to avoid
- you need a production-ready, mature linter with a large rule ecosystem (use ESLint instead)
- you rely on ESLint plugins or custom JS-based rules
- you need actively maintained software - the project is WIP with sparse releases

## Facets
- artifact type: cli-tool
- maturity: experimental
- function: linter, parser, cli
- domain: developer-tools, web-development, frontend
- platform: windows, rust, cli
- tags: javascript-linter, typescript-linter, error-recovery, parallel-linting, rust-crate, work-in-progress, javascript, linux, macos
