{"library":"xo","type":"library","category":null,"description":"XO is an opinionated JavaScript and TypeScript linter that wraps ESLint, providing a zero-configuration setup with strict, readable code defaults. It aims to streamline code style enforcement and eliminate style-related discussions in pull requests. The current stable version is 2.0.2, with a relatively active release cadence to incorporate updates and maintain compatibility with its underlying dependencies. Key differentiators include its batteries-included approach, which bundles many useful ESLint plugins (e.g., `unicorn`, `import-x`, `n`), automatic caching for performance, first-class TypeScript support, and flexible integration options, including optional Prettier usage. It mandates an ESM-only project structure for optimal functionality.","language":"javascript","status":"active","version":"2.0.2","tags":["javascript","cli-app","cli","xo","xoxo","happy","happiness","code","quality"],"last_verified":"Wed May 27","install":[{"cmd":"npm install xo","imports":["import xo from 'xo';","npm init xo","/* configured via 'react' option or implicitly */"]},{"cmd":"yarn add xo","imports":[]},{"cmd":"pnpm add xo","imports":[]}],"homepage":null,"github":"https://github.com/xojs/xo","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/xo","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/xo/compatibility"}}
