Version Details and Security Vulnerabilities

eslint-config-next provides a shareable ESLint configuration specifically designed for Next.js projects, ensuring code quality and consistency. Comparing versions 12.0.0 and 11.1.4, developers will find subtle but important distinctions. Both versions rely on core ESLint plugins like eslint-plugin-react, eslint-plugin-import, and eslint-plugin-jsx-a11y for React-specific and general JavaScript linting. They also share dependencies like @typescript-eslint/parser which enables ESLint to understand and lint TypeScript code. The most notable difference lies in the version of the @next/eslint-plugin-next dependency, aligning it with the respective Next.js versions (12.0.0 vs 11.1.4). This plugin offers Next.js-specific linting rules, ensuring best practices for performance, security, and accessibility within the Next.js framework.

Essentially upgrading from 11.1.4 to 12.0.0 is important when upgrading your nextjs version as the peer dependencies of eslint, typescript and nextjs remain compatible, ensuring a smooth transition. Both versions maintain the same peer dependency requirements for minimum versions of Next.js, ESLint, and TypeScript, meaning that the upgrade's main focus is compatibility for Next.js 12. Developers should upgrade to the eslint-config-next version that matches their Next.js version to leverage the most relevant and accurate linting rules for their project. The MIT license ensures flexibility and freedom in using and modifying the configuration.
