TurboLint

TurboLint is a fast Rust CLI for JavaScript and TypeScript linting.

Install

npm install turbolint-cli

Then run the published binary:

turbolint ./src

What it does

• Recursively scans .js, .jsx, .ts, and .tsx files
• Ignores node_modules and .git
• Flags eval(), var, and console.log()
• Exits 1 when violations are found, 0 when the tree is clean

Build the native binary

cargo build --release

Run locally

./target/release/turbolint ./src

The npm package ships the same command name and falls back to a local Cargo build if a native binary is not already present.

Need a fast second opinion?

Buy a $1 TurboLint Express Audit for one JavaScript or TypeScript file. You receive the findings with line, column, rule, and one concrete fix recommendation. Start the audit in Stripe.

Flags

• --config PATH: load rule toggles and extra ignore patterns from a JSON file
• --ignore-file PATH: load extra ignore globs from a text file
• --json: emit structured JSON output with scan stats and violations
• --fix: apply safe autofixes for no-var by rewriting var to let

The repo also ships a lightweight public site in site/. The live hostname is turbolint.ideatr.dev; GitLab hosts the public source and docs, while Vercel serves the live site.

Paid Microservices

TurboLint is free and open source. Paid support starts at $1 through a focused Express Audit, with additional repo review and agent services available when you need them.

Live paid surface:

• $1 Express Audit for one JS/TS file
• repo-level configuration reviews
• live NEAR Agent Market services
• direct USDC or ETH support on Base, Polygon, or Ethereum

Architecture

• Streaming directory traversal: paths are pushed through a bounded channel, avoiding full-tree materialization.
• Fixed worker pool: worker count is bounded by logical CPU availability.
• Memory-mapped file reads: source files are mapped read-only and parsed without copying the entire file into a new buffer.
• Parallel directory crawling: traversal uses the ignore crate's parallel walker instead of a single recursive loop.
• Per-file memory lifetime: source text, line index, Oxc allocator, AST, and rule state are dropped immediately after each file is processed.
• Bounded queues: the path and result queues provide backpressure under very large repositories to keep memory usage predictable.
• Single-pass file counting: the directory walker records scanned files while streaming paths to workers.

Release

Install it from npm with:

npm install turbolint-cli

That gives you the same turbolint command used by the native build.
