oxlint.json in Preact source code.

I found a file named oxlint.json in Preact source code. I wanted to learn more about this. In this article, you will learn what this file is about.

Oxlint is a linter

oxc-project is an organization that provides a collection of JavaScript tools written in Rust. Oxlint is a linter.

The below information is picked from oxc docs.

Oxlint is designed to catch erroneous or useless code without requiring any configurations by default.

Note: 

At the current stage, oxlint is not intended to fully replace ESLint; it serves as an enhancement when ESLint’s slowness becomes a bottleneck in your workflow.

We recommend running oxlint before ESLint in your lint-staged or CI setup for a quicker feedback loop, considering it only takes a few seconds to run on large codebases.

Features

• 50–100 times faster than ESLint, and scales with the number of CPU cores (benchmark).

• Over 480 rules with a growing list from eslint, typescript, eslint-plugin-react, eslint-plugin-jest, eslint-plugin-unicorn, eslint-plugin-jsx-a11y and many more.

• Supports

1. .eslintignore.

2. ESLint comment disabling.

3. Partial ESLint v8 Configuration in json format
