Oxlint

Oxlint — High-Performance JS/TS Linter

Oxlint is 50-100x faster than ESLint. It ships with 690+ rules covering ESLint core, TypeScript, React, Jest, Unicorn, jsx-a11y, and more. It prioritizes high-signal correctness checks by default — things that are incorrect, unsafe, or useless — so teams can adopt it without drowning in false positives.

Detection

Before linting, confirm the project uses oxlint by checking for any of:

• oxlint in package.json devDependencies/dependencies
• An .oxlintrc.json file in the project root
• An oxlint.config.ts file in the project root
• An oxlint or lint script in package.json that references oxlint

If none of these exist, the project doesn't use oxlint — don't run it.

Running Oxlint

After code changes

Run oxlint to check your work. Prefer the project's npm script if one exists:

# If package.json has a lint script using oxlint
npm run lint

# Otherwise, run directly
npx oxlint

Fixing issues automatically

npx oxlint --fix

Use --fix for safe automatic fixes. Avoid --fix-dangerously unless the user explicitly asks for it — it can apply unsafe transformations.
