@adonisjs/eslint-config provides ESLint presets used by the AdonisJS core team, offering pre-configured linting rules that work alongside Prettier. It includes two main presets - one for package development and another for AdonisJS application development - with automatic Inertia support when the relevant package is installed. This tool is designed for developers working with AdonisJS who want to maintain consistent code quality and follow the framework's established coding standards.
